Crosman sells replacement parts. As for machining one from scratch it depends on exactly how detailed it is and the meterial it's to be made from. You got pics? Part number?

Finding an existing part is usually cheaper, although it is quite and old model. Parts list here.

I don't think job weld is going to hold. It is pretty detailed and you guys are right, it will be cheaper to just purchase it. I found a website called jgairguns that has the part I wanted. :D A bit more expensive than I thought though.

How is it broken? JB Weld on its own won't help, but you could maybe drill a hole through both halves and insert a pin.

It would be too tedious, and I already ordered a replacement.

I have been printing gears as well, but machined a set of gears too. Trying to make my HPA pump electric.

wyz, 1:1 ratio, hmmm. Can't help but notice those teeth are roughed out a bit. Besides all the setup and time to get an accurate gear I can't imagine having to grind an HSS blank into the correct cutter profile.

Was building a M4 GBBR, wasn't very satisfied when the WE bolt carrier arrived. So I googled some images of custom AR bolt carriers and started drilling/milling mine to make it slightly more acceptable. (my camera doesn't really demonstrate how good it looks in person)

Hey guys, Its been a while!

I've grown up a little and gotten off my lazy bum and now have a job, with a small amount of money saved up. Ive made the decision to buy a lathe and am looking into the sherline! It should be perfect for starting out and small, airgun related builds.


Hit me with tips and tricks! Things to keep in mind and remember to do. Maybe things you wish you woulda known when you first started machining.


Maybe we could start a new sticky like "Beginner Spud-Machinist's Handbook"...? If not, hey. Just a thought.

Well, back in 1980 when I first used a metal lathe (South Bend model A10 IIRC) I wish there would have been home PC's and websites like Spudfiles with a 69 page long machinist thread to study from just 'chucked' full of tips and tricks and links to learn from. :bigsmurf:

Save more money or shop used, but get something bigger. 1" through the spindle is IMHO a minimum.

Used will likely come with tooling which would other wise have to be purchased separately...which adds up...trust me.
