Erik, take your pick. NBR Works 2025-08-15 | I was invited to Toolroom Takeover 2025 and, lucky me, I was chosen to gift the Boss.Some say the draw wasn’t rigged, but after running that Python script five times and getting the exact same output, I have my doubts.Anyway, I had big plans for the Boss — only challenged by the fact that 2025 is one of those years with only 12 months. That, and the videos had to be out in August. Mid August, "not the end" - I was told. Oh, and there was something about the shipping time...Between the drawing and sending my "gift", I had 1 week to make this project. I feel like it was more like 5 days. Part time. Don't expect much.For the same reason, there wasn't much time to make a proper educational video, so today you're getting something else. Call it entertainment?500V is a lot to play with, especially when you have a very basic understanding of electronics."Safety first" is not only a great motto, but also something I didn’t have time to address in this *entertainment* video.Seriously, building amplifiers is cool, but you can die. If you do, I had nothing to do with it.Finally, I got something from Alec Steele, and got my MK1 Mini out of the garage for the first time in 5 years. Would you like to see it more often?

How a Solid Tool Post Mount changed my lathe NBR Works 2023-09-21 | Parting or cutting off steel has always been a challenge on my lathe. Issues range from heavy chatter to broken inserts and tools which end up stalling the motor and sometimes damaging the work done on a part.Today we're making a solid tool post mount to replace the compound (top slide). The compound on small lathes is known to have rigidity issues and that's what we're looking to upgrade.Tools I use: nbrworks.com/toolsHave a look at these other videos that served me as inspiration for mine:Robin Renzetti's: youtube.com/watch?v=pG3YSfgyJPIPhil Vandelay's: youtube.com/watch?v=Y3N5k4rmf9oStefan Gotteswinter's: youtube.com/watch?v=bLn0Ch1_KQMTimestamps:00:00 The why01:07 Squaring cross-slide register slots02:23 (Kind of) Squaring a cast iron block03:24 Solid mount registration feet05:25 Improving top/bottom parallelism07:20 Machining angled ends07:48 Fitting the Quick Change Tool Post11:20 Cold blueing11:36 Replace the compound with the Solid Tool Post Mount13:27 Parting off tests (12L14, 4140, 304 stainless)#lathe #diy #machineshopyoutu.be/kJhBPm7hkec

Lathe rebuild Pt.2 - The apron, a quick change tool post and something about the gearbox NBR Works 2023-05-14 | Hi everyone. This is the second part of my HBM lathe rebuild.We'll go through the apron where I spent hours deburring all the parts (but that's boring, I'm saving you from that), then we'll replace the 4 way tool post with an Aloris replica (wedged quick change type) and finally we'll look into the gearbox that allows to reverse the direction of the lead screw and easily select one of 3 feeding speeds according to the change gears mounted.We'll also briefly look into the compound, which was thoroughly deburred, but not lapped (I didn't feel the need to).Since I had too many hours of footage to process and squeeze in a short video, I've chosen to go over some clips in fast forward. If you have a similar lathe and want to look into something specific in detail, leave a comment down below, I might have the footage and I'll be glad to help.Finally a note to my colleagues at work: I hope this serves as proof as to why on Monday mornings I was showing up at work with blue fingernails - No, I'm not 'having fun' during the weekend.Tools I use: nbrworks.com/toolsTimestamps:00:00 First chips00:14 Meet my lathe's apron00:45 How the apron works02:51 Getting the apron back together03:35 The new Quick Change Tool Post (QCTP)06:24 The gearbox06:43 Something about crash type gears08:02 Closing the gearbox08:35 Adding magnets to the gearboxes oil plugs08:54 A steel plate and rigidity09:35 ClosingLathe: HBM 250x550 Profi VarioLathe rebuild playlist: youtube.com/playlist?list=PLQmkDSE3SwYu6sWilKMYVBtqX7Vr8Qr-_#machining #lathe #diy youtu.be/0ktNqw_muUY
