[CS900]

hey guys, thought you'd all like to see my latest creation that me and my Taig (with a little help from my lathe) just finished up. it's a paintball part that the air regulator screws into. nothing overly special, but kind of fun to make. enjoy

Beautiful!

Care to describe how did you do it?

sure. here's the short version:

it started out life as a rectangualr piece of AL stock. it was then slapped on my lathe where the threads and internal features were made. from there it was tranfered over to my mill where it was clamped on angle blocks to achieve the angle you see in the ~nearly~ finished picture. While set up like this, the top surface, locating peg, and oring groove were machined. I then proceeded to make a custom fixture which consisted of a brass cylinder, the same OD as the oring groove's ID, with a concentric tapped hole in the center. This was placed in a 4th axis rotary table and trued to the mill's spindle. The part was then bolted to this fixture having the oring groove fit tighly over the fixture. From there it was just a matter of indexing the part while machine the outside profile. Pretty simple actually, but was alot of fun to make.

since you asked about the procedure, here are a few pics that might help visualize what I was saying:

Nice work :-)

Can I possibly bother you for some more details on how you did the internal threading and what you used to do it? I am a total nuwbie and this would be a big help! I just purchased a sherline CNC lathe and it will be here soon.

It's part #1200 ($20), and it fits in the regular toolholder, so you don't need the boring bar attachment. Drill a 1/4" (min) clearance hole, and use the hand-crank threading attachment. For smaller internal threads, use a tap.

Thanks for the reply. Can you tell me where to buy this part at?

You can buy it from sherlinedirect.com if you want the Sherline version. Or just search for 'internal threading tool' on any of the tool sites like MSC, McMaster-Carr, etc.

Thanks for the help. Got my thread tool on its way. Now to learn how to use it.

yeah, the threading on that part was done on a lathe with a single point bit.
