Hi Folks,

Here is an introduction video for the Rose Engine, a companion machine to the Straight Line Engine for generating Guilloché. Much like the recent SLE video I have put this video together without narration, as more of a chill out thing. The plate material is fine silver, the pattern is sometimes referred to as 'Escargot' and the pendant is an anniversary gift for my lovely wife. The enamel is from Milton Bridge, 263 Series K62 Jade. More detail on the casting & finishing of the pendant structure in a later video.

Do please enjoy!

Cheers,
Chris.

$Spare Parts #13 - Making A Square Broach Making A Square Broach, by Clickspring. Its not necessarily a common event, but when you need to make a square hole, it can be difficult to get a precise result. One of the best methods to achieve a professional cut is to use a custom made broach, so in this video I go through the process of making one from scratch.

And the other key feature is the pilot diameter, which must be centered on the square, so Im taking care to center the raw stock prior to forming that cylindrical shape. 01:48 I have the work reasonably well centered to begin with, so that when I position the dial indicator, the error that I see for each jaw is quite small I then use 2 chuck keys in opposition to each other, to move the work, so that the dial reads directly between the original 2 readings for both jaws. 02:13 Once its close, I move the zero reference to that point, so that becomes my target when I start to center the other two jaws. Once the work gets close to being centered, the errors start to sit nicely either side of that zero reference, and it gets easier to pull it into position. 02:53 But even doing this quickly, you can see that it will take a fair amount of time to do this for every cut, so theres a strong incentive to bypass this centering process if we can. For now though, the work is centered, so I can make a start on cutting that pilot diameter. 03:39 Next Im using the first groove position to register the tool after extending the work, and then Im using the hand wheels to advance the tool the required amount to form the next groove. Now inevitably I will have introduced a small eccentricity to each of these cuts, and the teeth wont be precisely spaced either. But as I mentioned before, they dont really need to be. 04:14 Providing I dont introduce any gross errors, Its close enough for the final result, and by accepting a small error, I can move through this part of the process very quickly. 05:14 The total amount of metal to be removed, is determined by the difference between the pilot diameter and the diameter of the circle that just encloses the final square. That metal removal must now be shared across all of the teeth, so it determines how much I feed out before cutting each tooth, and that in turn ends up determining the broach depth of cut. 05:32 The diameter difference also gives an indication of how many teeth are required to keep the chip load manageable. 06:15 At this point all of the features of the broach have been formed, so it can now be quench hardened, and on this occasion Im using the tray that I recently made for the current clock project. 07:07 In an industrial setting a broach is far more likely to be pulled through the work rather than pushed like this, and theres a real risk of fracture using an arbor press in this way, so be sure to take it carefully. 07:19 Make sure the broach is perfectly vertical before you push it through, and as always have your eye protection on. But even with all of the compromises, its still a great way to use home shop tools to quickly shape a precise square hole. Making A Square Broach, by Clickspring.$
