Headstock casting - cleaned and ready to bore

(Chris Small) #1

Evening all.
I’ve been tied to home for the last couple of weeks so I’ve used the time to continue work on the headstock casting that I posted a couple of weeks ago. It’s been filed to fit the ways and the clamps have been made for the box-slide ways.

Temporary mountings for the boring bar have been completed. I assembled the thing to test that it’s going to run, approximately, as required, and to run the temporary bearings in a bit. I also need to shape the grooves in the pulleys to a more reasonable profile before I start this exercise, and need to do some work on the extra pulleys so that the lead screw rotation is geared right down.

It’s getting there.


I am in awe !!!

I didn’t know how to include a video, the other day, when I posted this. :smiley:


Today I acquired some 24.8mm threaded rod from a Men’s shed cleanup.

Thread is pretty clean/sharp and straight rod. 1x1500mm and 1x2100mm.

Made me think of your project…and dreaming of a project for myself.

Would any of that thread be useful to you?

Hi spanner888,
Thanks for your consideration! I still have a couple of bits of that size that I haven’t used, yet - well, roughtly, (3’x1" 8tpi) (I tend to work in inches because I’ve found it easier when working from American doco, though not always - parts availability is sometimes an issue).

I bought those when Masters was finishing up, and, because I was looking at building a Yeomans-styled concrete lathe. I opted, in the end, to try to build something that’s a bit more of a hybrid that steals from Yeomans, G.B. Round, Romig and Gingery. The idea/design is sound, enough, but I’m still finding alignment and boring difficult.
Cheers, Chris.
