Title: Machine question
Post by: Pellet Fun on October 28, 2021, 08:37:29 PM

Bob I just went back over your .25 Carbine and Millennium pumpers.

How did you machine the slot in the Disco compression tube for the pump arm? Silly question but since the material is so thin I keep wondering how you achieved this.

I'll read your build again for knowledge and enjoyment. As others have described it was an amazing build.

I used the milling attachment on my lathe, with an end mill in the chuck.... I started with a row of holes and then changed to the end mill to change that into a slot.... With a real milling machine it would have been a lot easier.... My milling attachment only has 6" of travel, so I had to reposition the tube to get enough length....
