I finally finished the carriage stop for my mini-lathe that I've been working on intermittently for some time. I've had occasion to use it now and don't know how I lived without it. It's funny... Stuart and I were working on almost the same project...

Nice work man! You already said it- you won't know what you did without it!

I made a replacement front sight base and blade for my Crosman 2300T air pistol, using my Big Dog (Real Bull) 7x14 lathe and Grizzly G8689 mill.





The blade is held in the slot with a Loctite brand rubber-filled cyanoacrylate glue.

It's not quite finished. I need to run out tonight and by a set screw assortment then drill and tap a hole for one in the bottom of the base, then blacken the sight blade.

I needed a small lens cap

Great cap. What tool do you use on the lather for the internal grove? Where did you find the specifications for the grove size for that Oring?

I have had some of my tooling for over 30 years...most still had plasticote on them....last week i opened them all up now that i finally have a lathe of my own and i found a nice carbide id groove cutter..

i just measure the oring thickness and cut minus 5 thou

If you have a Parker distributor nearby, request a ORD 5703. It's a booklet that is a great guide for designing seals. The number may have changed, but the counter guys ought to know what you want. There is also an online version of you don't have a distributor handy:

A bit lengthy video of a column mounted pulley speed change for my 1930's atlas lathe. I didn't do it today, but what the heck. Here it is. Skip to about the 5 minute mark to get to just the pulley part.
