A bit late to the party here, however something I saw here falls into the "why didn't I think of that" category. Using a die to hold a threaded part for light finish work or bench work. Brilliant!

I love shapers. I will purchase one in the future. Thx for shaper content.

Shapers are fascinating tools and any shaper footage is welcome :) even if in Alaska where I am, a Unicorn is more likely to be found. I must look at my height gauge to see if I can change the tip. I prefer digital gauges because I work in metric, and the analog readouts do not do this stunt. Bought mine from Lee Valley so we will see.

Nice job - thanks. It was a useful reminder of a technique I was aware of but have not yet used. I was surprised that the part drove OK without a drive dog. I guess that was a live tailstock centre. Best, Mike UK

Thanks Mike, I appreciate you stopping by. I don't always use a lathe dog - you are right the live tailstock centre allows me to get away with this. I use it mostly for finishing, and since I use LH Sparey's method finishing using HSS involves about a .001" DOC - not very much load.

Well done, Justin. A nice addition for your analog CMM. :-) The bacon fat reminded me of Henley's Formulas which recommends 1 part graphite mixed with 4 parts tallow to lubricate lathe centers.

Thanks Hans. Yes, I do recall the Henley's formula as well, although I don't think I heard it from Henley's. You need it for your dead centre - otherwise you ended up with a part welded to your centre. No bearing runout with a dead centre. Of course 100 years ago dead they were everywhere. Since the introduction of the economical precision roller bearing live centres have taken over. I don't think hardly any younger folk working in the trade even know what a dead centre is.

Great video Justin, and great job on the arm! :) I agree about knurling, for those bump-style knurlers setting them at a slight angle makes all the difference in the world on smaller machines like ours. Speaking of which, how burly is that leadscrew on your lathe?? Holy smokes it must be at least twice the diameter of the one I had on my old Chinese machine. I'm glad you like the boring head, and that it worked well for you. My video will be up soon, and everyone will be able to see my boring head as well as my boring. head.

Thanks Max. I really want to make a scissor type knurling tool - it's on the growing project list. They do a much better job and reduce the force significantly. That and buy some knurling wheels that aren't made out of cheese. I just used the one that came with the import piston tool post. The lathe has a huge feedscrew, I think it's around 3/4 - 7/8 of an inch. The feedscrew is also fairly well made. It's a strange TPI though (7) so it makes for some interesting thread cutting - although it does do both metric and imperial threads. Boring head worked great. I can't wait for your music pick.

I always thought I'd make a scissor knurling tool too, until I got to use a cut knurling tool. I would make a cut knurler (or set of cut knurlers) in a heartbeat now, rather than any other design. Literally effortless, and they come out perfectly full depth in one pass.

I just looked into cut knurling. I'm kinda excited - I can make the knurl wheels myself on the shaper with a dividing head. Interesting .... I wonder how deep this rabbit hole is.

to reiterate what's been said in just about every comment so far: excellent job (&, in addition, a lovely, high-production-value, very entertaining video); been wondering about the feasibility of using boring heads instead of reamers for small-scale holes (i use a shared shop, & all of the reamers are basically miscellaneous - precise hole making basically involves spending an hour trying out likely candidates with gauge pins, to see what ones give me the for I'm looking for), & this video just about convinced me to start looking for some tooling

Thank you for the video ! Nice design, & nice work. I'm a bit jealous of that boring head. Do you down-feed manually ?

Thanks Alistair, and thanks for stopping by. Never feels like work man! I really do enjoy machining and working in the shop. To me there is something special about working with your hands, whether for pay or play.
