Single stage press upgrade

[Smoothride]

I have an old Lyman Comet. I wanted to use Hornady Lock N Load bushings but it had odd 1.1-28 thread. Chucked it in the Bridgeport and bored out for the correct hole for a 1 1/4"-12nf thread and tapped it. Total cost was the Hornady bushings and $20 for the tap on eBay.

Nice work!

How difficult was it to tap the threads?
That large size in cast iron must have taken quite a bit of torque to turn that tap?

My experience working in a machine shop, the big ones usually tap pretty easily with a sharp tap and some lube. Cast iron taps pretty easily, it kind of flakes apart like powder.

Pretty slick. Nice job.

Great job giving an old girl new life.

Would love to do that with my RCBS Jr but my mill is way too small.

Tapped really easy. And I had to offset the head on the mill to let the press hang off the table to get the necessary clearance.

UuuZzz wooined it!

Cool so many older presses go to rot in the corner if a shed because of the older thread styles

A true genius operation!

This guy seems like the type on a fixed income not actually a skinflint

With access to the tooling and machines, I'd say he is someone who enjoys the challenge of the job.

I can easily afford locking rings for my dies but I did a cad model and printed out a bunch of rings because I enjoy the work.
Same goes for many of the designs I have out on Thingiverse - would have been cheaper/faster to just buy instead of making the parts

My comment was a rare opportunity to bust the ops . He is a personal friend. Also very talented

It was 1 1/4"- 12..... Not small nor do I think it would break.
