Involute Gear Cutting on the Shaper final
updated
A quick update video as we install the 25mm foilboard external insulation to our compact cottage.
We are hoping to get the roof and two end wall colourbond steel panels installed before heading back to work next week!

Every time I go to refill my Dewalt battery powered grease gun i keep thinking there must be a better faster cleaner way to refill the bulk cartridge.
Well today I think I have finally figured out how to avoid the total and absolute failure that occurs every time I try to draw grease into the tube from a bulk grease tub.
Let me know what you think!

the floor level of our slab is 5 metres below the rainwater tank, so we do not need a pump to provide pressure to the water supply.
Our hunches led us to suspect a fuelling issue, so I suspected a fuel cut solenoid.
The only electrical component anywhere near the diesel injection pump was located in a nasty location, out of reach of normal tools.
Thus some major disassembly of the pump and engine mount bracketry was required to get enough access to undo the part.
Next step was to try to find a replacement, but this was discontinued! So the last resort was to attempt a repair on what remained of the part.
Join us as Bruce Whitham and me get up to our usual hijinx, lose the patient a couple of times on the operating table, have a brief intermission to repair Bruce’s laser tape measure, then get back to work with Bozo ever vigilant to catch us out at a moments notice!

Happy new year, may 22 be the year that 20 was meant to be.
We highly recommend Hugh’s pizza dough recipe from River Cottage and this design is inspired by the wood fired pizza oven built on that show
A quick video showing a number of small jobs completed recently that help to keep our Backhoe fighting fit and ready for work. A small leak at the lift pump was resulting in the motor stalling at inopportune times. The front boots had seen better days, the starter solenoid was no longer throwing far enough to engage the starter, so it needed a screwdriver to start, and the centre tooth root had fractured and was no longer keeping the tooth. All in all a quick few hours work, with some great results :-) thanks for watching
After nearly 30 years on the machine without any lubrication on the top pins of the stabiliser legs, the workshop manual instruction to “remove bolt, then remove pin, then lower leg” ended up becoming a 3 day ordeal!
We did overcome however, here is some footage of how we did it!
I’m sorry it’s been so long since my last video, I’ve had some personal issues I’ve needed to work through.
I’m happy to say we are now back on deck, and pushing ahead with new content, new life goals, and lots of fun and hopefully interesting content.
In this video we start to work on a Perkins Diesel Generator that we purchase site unseen.
We were told it was 25kva, 3 phase, and that it did run.
As most of the machines we have are 3 phase, and there is no chance the street power will ever be 3 phase here, we jumped at this chance to have a decent sized site power supply.
To see more of our Site Power Shenanigans, I hope you enjoy this video :-)
It’s been a while between videos my friends, lots going on and trying to catch up on the regular duties once we got the slab down on the house has kept me busy
Autumn is here, and the garden is looking great, we have had some pretty nice yields from our tiny space garden.
Hope you enjoy!
This is a quick video to capture for posterity the really nice Chinese lathe that we acquired with the Precision Machining Workshop batch of gear recently. Dad has spent some time cleaning and checking through, and this showed its class very quickly. The machine is solid, and mounted on a heavy cast iron base, certainly much better than the cheaper end of the market we are used to seeing!
Thanks for watching
The dynasaw has been acting up a little, with the starter solenoid only engaging with the engine in specific locations (where the ring gear meshes with the starter pinion) thus the old hitting with a hammer or bump starting to rotate the engine has been the method of choice lately.
As dad recently sold the green Chinese lathe, and was delivering it with the truck, being able to start it trouble-free became this weekend’s job.
I had purchased a repair kit, however the starter ended up being a slightly different model, so the kit didn’t fit, so instead, we shimmed up the copper contacts with some cardboard to allow the solenoid to engage earlier in the stroke, solving the problem.
Unfortunately footage of the cardboard was lost, so you will have to trust me that this was the fix we employed, sorry!
Today we caught up with Adrian who has a 1958 Austin Champ for sale
Suitable as a parts car, or for the super keen, a ground up restoration?
Located in the leafy suburbs of Perth Western Australia, should anyone be interested to discuss further with Adrian let me know and I can put you in touch with him.
Vehicle rolls on its own suspension, motor is a Rolls Royce motor and claimed to be in good condition.
Apparently in this era all the wiring is shielded (grounded) to protect from EMF for this vehicle
I will leave it to a prospective purchaser to take their own assessment of condition value and suitability for any purchase!
If you know of anyone who might be interested please let them know
Thanks team :-)
In this video we make a start on clearing a space for the machinery, underneath a stack of what was once gorgeous lengths of 100mm square (4”) Jarrah posts, now just so much termite poop :-(
We also get the Colrol truck mounted crane fixed on the Dyna-saw... and clear some room at home for the next project there!
Mates Rates - machinery moving mission
Not the beer fridge!
After many years of faithful service the kegerator insulation had degraded to the point where a massive iceberg was developing on the outside of the freezer compartment.
In this video we attempt a DIY insulation repair, and waterproof seal, to save our beer!
With a strict deadline to meet and a number of challenges with machinery, I have been very fortunate to have help from many quarters.
In this video Reg T again features with assistance on plumbing and general set out
The usual suspects once again pitched in, and my cousin Daren kicked in with advice and hard graft on the concrete pour and finish
We have chosen black concrete and a troweled finish.
As the pour was in high temperature and reasonable winds, and with little chance of keeping the slab wet using ponding techniques, we selected a chemical membrane to slow down the curing process of the slab and reduce the likelihood of cracking
We have also included a network of vent pipes 100mm openings through the house with the intention of drawing from a subterranean heat sink field, to provide year round passive air conditioning
Stay tuned for more progress as we build out this project!
In this video we manage to break and fix the backhoe many times over, deal with stubborn pins, carby problems on the baby plate compactor, and the increasing temperature as we head into summer.
In the end and with the help of good friends, we get the earthworks completed, the successful compaction test and a plan for set out, plumbing pre-lay and concrete preparation.
At this stage we are making good progress, with our goal to complete foundations by end of December to qualify for the state grant.
Huge shout out to:
Reg T, advice, supplies, and old fashioned hard work
Max Grant, for the loan of his whacker-packer, form boards and support
Bruce Whitham, for not one, but 2 getter-outs on stuck dowel pins on the backhoe hydraulics
Ed Donnelly for the use of his workshop, his beers, and many days on site fixing and driving machines
Mal Wilson for hard work dedication and good times
Jaimie Hill for help on the levels and set out
Everyone else along the way providing support assistance and encouragement thank you!
After long and careful consideration we have finally had our building permit approved, so now the fun begins.
We started clearing the topsoil with the skid steer, however due to a hydraulic issue, we had to switch to plan B
This means some repairs to the Backhoe, which had sprung a couple of leaks in the steering ram and main lift ram.
Bruce Whitham gave us a quick hand removing a recalcitrant dowel pin, which was stopping us from replacing the seals and rebuilding the ram.
Thanks for watching!
Thanks for joining us on this quick glimpse of the home garden. Seph has been planting out the wicking beds we made earlier this year, along with lots of great mulching, water retention strategies, companion plantings and organic (pesticide free) options for building soil fertility and garden health.
We are seeing a great diversity of birds, reptiles, insects, bees and a huge variety of symbiotic plants species we are seeing the ongoing benefits to our lives
The summer shade of the bottle brush has been missed this summer however the massive mulberry continues to provide afternoon shade from the worst late day heat, and the morning sun into the kitchen in summer is blocked readily by the apples, plums, pomegranates and Lilly Pillies.
Soon I will have some videos of progress out at the farm, the last 6 months since deciding to build a tiny house have been jam packed with excitement and organisational demands.
We finally got our slab on ground yesterday, so taking a breather today, as I prepare to edit all the footage from this next project
Thanks for watching!
This is a blessing in some ways, as I can see things others may not, and I am open to new teachings, where others may not be.
Robert M Pirsig in 'Zen and the Art of Motorcycle Maintenance' taught me a philosophical approach to my life,
"In a rush to change the oil on the protagonist's motorbike, the drain plug is stripped, now instead of going for a ride, the rest of the day is spent trying to fix that mistake. Had the first operation been approached with more care and respect, mindfulness of the future impact of that operation, the mistake would be avoided."
This he calls a "Block". Blocks creep up on us when we least expect them, travelling along then suddenly BAM.. block.
I believe Joe hit such a block when he went to set the alignment of the flange once the centre was locked.
There was no way to avoid the error caused by the earlier machining operation. the choice left to him was:
1. Align one hole centred to the flange, and have the other well off centre, or
2. Have both holes off centre to the flange.
The third option he claims was not available... to centre both holes to the casting ears, was no longer available due to his earlier operation, machining the boss to final dimension.
It would have been available if he had been mindful of the features the centreline was referencing in the drawing, set the part to the centre prescribed by those features, and then proceeded with the pressure turning operation.
The oversized centre boss is not shown on the drawing.
The old adage 'Measure Twice - Cut Once' is also fitting.
In the rush to complete a part, a critical positioning error was made in locating the centre of this part without considering the outermost features most impacted by positional error.
By working from the outside in, errors scale down not up.
Few are the teachers that can not learn something from their students.
Joe has answered the question I was asking in comments on his video (massive thank you Joe!):
My Question: Assume the print indicated the machined features to be centred on the casting, how would you accurately position the machined features to the remaining un-machined faces on the part.
Joe's answer:
"There are several ways to align the gland before machining. One is you incorporate what is called the inscribed circle. Find a pin or turn a blank that sits tangent to all 4 sides of the gland body and establish the boss concentricity that way."
(my summary) This would thus position the part, pressure turn and continue other operations.
My suggestion: using the same slug Joe used, scribe a cross hair passing through the centre of the part.
Instead of bumping the part to centre on the (later to be machined, non reference surface of the finished part, boss);
Align the part by eye, so the outermost arc features are bisected by one axis of the cross, and the centre arc of the gland bisecting the other arc. this is a fast, accurate way of getting the best outcome using the exact same fixturing Joe used.
Once aligned to the cross hair, proceed to lock the centre hole and boss to that circle, and minimising the positional errors seen on Joe's part.
By working from the outside in, errors scale down not up.
Joe presented a list of 10 points for me to address, to do the response justice, I have recorded a follow-up video.
These same questions were repeated by another commenter on my video (gday
@ShopTech! hopefully this addresses all of your questions, if not, please be sure to let me know!)
Hi, I’m “That JB Guy”.
You might know me from such films as
‘What’s in your box 2016'
‘Gear Cutting on a Shaper’
‘Rebuilding an AL960B lathe’
'Servicing and repairing industrial embroidery machines'
'Rebuilding earthmoving equipment'
'3D printer builds and upgrades'
I’ve published over 300 videos over 5 years, on this amazing democratising happy place called “YouTube”
Not far off 50 years old, I’ve had a lifelong interest in electrical, mechanical, and organic systems.
My early years saw me printing up to1200 shirts per hour (one every 3 seconds) up to 110 hours per week during the 80’s - fast - accurate - manual positioning.
Full bare metal rebuild of a 1959 Austin Healey, then driving it 3,000 miles across Australia, where Geoff Healey drove my car at the national rally.
I’ve worked 10+ yrs as design manager/R&D manager for a 5th generation precision print business, responsible for accurate design of tooling, print masters for membrane switches up to 7 layer laminations, embossing, resin doming, LEDs, tactile domes, and electroluminescence
5 years as prod. mgr, implemented digital order confirmations systems to eliminate scrapped work due to poor client comms.
My last 10 years has me delivering workflow automation. e.g. short term project delivering $500k/year additional output, no extra inputs
In short, I grok profitability, accuracy, speed, and cost.
Questions asked, Questions answered, Thanks Joe!
This weekend we took some more time to become acquainted with the internals of the stepper drive configuration.
Really excited to see the NVCM4 motion controller coming together.
This motion controller supports 4 axis steppers and a spindle output (0-10V) to drive the VFD spindle speed controller.,
This video shows us figuring out where the stepper drives will sit.
We have 2 supply voltages off the toroidal, 24V and 65V.
the Z Stepper drive is a high voltage unit, and will run off the 65V, the X and Y will be run off the 24V.
The NVCM4 board will be running on 24V, the stepper drives usually expect 5V to the opto-isolators, so we will need to use 2kohm step-down resistors on the step and direction lines.
Space is pretty tight inside the 2RU box, and a fan would be a useful addition to the boxes to keep airflow over the stepper drives.
We will be replacing the PC originally used to run the Sieg, with a 2RU Motium rack-mount box, and with the bluetooth pendant, it should make for a nice little upgrade!
Recently we have seen a couple of talented YouTubers drawn into a somewhat disturbing outcome.
As you will know from my videos, I am a mere hack, my knowledge is presented for entertainment, and I make no claims to be a journeyman machinerer, educator or sage.
For what it is worth, I feel Quinn also presents herself warts and all as she shares with us her machining adventures.
Joe Pieczynski has a long history of production machining and brings us a high quality information driven channel, with many very cool theoretical and practical hints tips and tricks.
Unfortunately there is a gap between sharing and teaching, and taking down others, it leads an audience to be more critical of the teachings being given.
I am uncomfortable with the results shown most recently by Joe, so I called him on this.
In fairness, his response indicates a degree of pragmatism borne of production realities.
My concern is that when "All you have is a hammer, everything starts to look like a nail".
In his response, Joe clearly states aesthetics has ZERO to do with the function of the parts he demonstrated.
So really the question is, are you making a batch of parts? or building a display model of a steam engine?
I know why I pulled down the working Stuart Models James Coombes engine I have, for a rebuild, and it wasn't because it ran badly.
It was the aesthetics.
Why keep building this engine if you don't care what it looks like Joe?
You seem to have missed the point.!
So today, to test the theory, a 24V switch-mode supply with plenty of grunt was thrown at the problem, which promptly vanished in a puff of PEBKAC and RTFM!
With that quick result, I’ve also added a few short clips of progress on Dad’s Sherline installation, we spent a few days sorting through a stack of boxes, mating up appropriate parts, dry fitting and finessing the collection. It looks like once all is said and done there will be a manual lathe, a manual mill, a long bed CNC lathe, and 2 CNC mills.
We needed a few more stepper mounts so I 3D printed a set on the Prusa SL1, including printed 10/32 UNF thread straight off the bed!
It will be interesting to see how these parts stand up to use.
Thanks for watching!
After watching Mark Preso doing some magic on his CNC, we realised this is all stuff we could and should be doing in the DesignLab workshop.
In this video we have added in the Tool Height Probe and MPG pendant (both I ended up purchasing from Banggood) and also commenced working with the Novusun NVCM4V2.1 USB Motion controller.
Being a dyed in the wool Mac user, most of my machines have never heard of a parallel port, and opens up a much wider array of potential host "PC's" for future.
We succeed in getting Mach 3 installed, adding the drivers included on the MPG and NVCM4, and then start with config/setup in Mach.
The Tool Probe looks smart, and after translating the chinese instructions (translation included at the end of the video) we see that the positional accuracy is 0.001mm, very tidy!
By wiring the "over distance" to the E-Stop, any over extension of the tool probe should fire off an immediate stop all to the motion controller.
Next up we attempted to get the motion controller driving a stepper in anger, however due to some voltage mismatch issues, we will come back to this in the next video,
Finally we verified the "spindle output" voltage 0-10V standard range for frequency control, means that we have an additional cool feature, Mach3 spindle speed and direction control
Thanks for joining us on this upgrade, dont forget to hit that like button, and ring that subscription bell.
see you soon!
This video shows progress on our new wicking beds in the front gardens, along with a temporary setback with a burst water main on the front verge!
Hopefully the Lemon Myrtle will survive, its taken years to get established without supplemental watering, and is getting a bit of extra attention at the moment.
Thanks for watching! see you soon :-)
Lots going on at the moment, so here is a very quick update of the swale and surrounding plantings.
Everything is much greener now, as the water soaks everything, and the dam retains a bit of moisture.
Thanks for watching!
Around six months ago I laid out my thoughts on a great way to provide regional funding, schools funding, and support the continuing rollout of community rooftop solar power
Today the WA premier announced a massive new program that targets pretty much every area that we hoped would be included in such a program.
Thanks for watching!
Here's the first attempts to play with this tool, and running short of time it does not show a finished result, however its a lot closer to the right spot than it was before!

Now we are getting serious about our off grid small spaces rural home, the question of heating, cooking and hot water supply arose.
Never one to do things the easy way, we have decided to restore this old oven back into full working condition.
Ok, so looking at what we have, there seemed to be a few critical pieces missing, and some damage that was a bit confusing, as to how all the bits come together.
As we were looking for more information, a pair of Rayburn 620 ovens appeared in marketplace, not too far from us.
Between these 3 we know we have enough good bits to make a really nice oven for the house.
So follow along, as we commence the first in a series of restoring a Rayburn 500 slow combustion oven.

With the recent changes proving “work from anywhere” does indeed work, commuting to town twice a week now becomes an option. So here we go! Site survey, bushfire assessment, site inspection, drawings and engineering. It’s going to be a busy few months ahead!
Wish us luck!
Cheap DIY Tiny House
We have entered each year, the first year was our Gear Cutting on the Shaper video, which has been one of the most popular videos on my channel.
This year, I attack the Blue LED Laser with some left-over Reprap printer parts. At first I thought an existing option might work for me, but the more I progressed, each item was different, so drove me to re-engineer from first principles.
I use my old favourite OpenSCAD, as it sits right in my wheel-house of programmatic 3D modelling.
By breaking out all critical dimensions as parameters, it is possible to recompile the design for whatever parts you have lying around.
LM8UU bearings? 8mm rods, different pulleys? belts? bearings? tweak and print!
I also constrained the sizes of all parts so they can be printed on my SL1 Prusa 3D printer, and tweaked a little for strength and support-free printing.
I hope you find this interesting, if there is demand for more information on any component of this build, please let me know, this video kept deliberately short to fit within the entry rules.
Thanks Emma, all the other #TMC2020 entrants, and of course, you, my valued subscribers, who are the reason I continue to make content for you here.

3 of these were roosters! Well that’s ok, a mate (G’day Luke!!) offered to hatch out some of the eggs for us, which resulted in 10 new babies, and we were hooked.
He hatched another batch for us, and eventually we purchased our own incubator to allow us to continue.
Our birds were in a large 2 section fox proof enclosure at our 15 acre permaculture property, and they thrives in the hot, dry conditions.
There’s a couple of pictures of the variety of egg colours and sizes, and also some of the offspring lost the naked neck trait, however producing some really beautiful roosters in the process.
We later acquired a frizzle rooster, hoping to produce some frizzle naked necks, but that was not successful.
Unfortunately our flock was destroyed when a couple of dogs broke in through the fence and laid them to waste :-(
Around our town property we had a couple of pairs of Bantam Silkie hens, who have now moved on to another home.
We do not have any birds at the moment, possibly considering some quails around town house, but the shock of losing our entire flock was pretty sad.
Maybe once we are settled out on the farm permanently we will consider starting again
The egg production was great, and they handled the hot dry summer heat in Australia wheatbelt very well
We are expecting a 1 in 10 year storm this afternoon so have spent the last couple of weekends pruning some of the bigger at-risk trees to make sure they survive without major damage.
We also make further progress on the new wicking beds, and extending the deck out between the two new beds.
One issue was apparent with the gear selector/throttle assembly, it was very vague and had trouble throttling whilst locked into neutral.
Here we go through what we learned whilst tackling this project.
But! With the trusty rodeo on side, and a steel bed tray, we can use this to hold the mesh firm while applying liberal percussive motivation in just the right spot!
Turned out Bonza Rippa Bewdy Mate!
Thanks for watching, stay safe, be happy
That anything is alive, much less thriving is a testament to the water capture function that swales on contour provide to hydrate landscape, and host trees. We have had many losses, but we have some good successes. Unsurprisingly, the olives are thriving. All of the Pomegranates surviving is very exciting! The ground mulch is starting to build up, and it is clear this is providing valuable protection for the remaining survivors.
This summer has been 6 months straight without precipitation, and with site temperatures in the 40s regularly, that anything survived at all is heartening
I hope you found this update useful.
Thanks and peace!
