The plug completed, I then did a little programming and made the barrel band on the Taig CNC mill.
A piece of 3/8" thick aluminum mounted in the vise. |
Notice it's supported on parallels well away from the center of the piece. |
Interpolating the barrel and plug holes with an end mill. While not as good as drilling and boring, it's close enough. |
Staring the contour cut. |
I took several passes around. |
In the end, the part dropped free. |
A bit of filing, sanding and general deburring and the part is done. |
I assembled the band on the plug and barrel. |
Drilling the end cap. |
Counterbore for #10 screw. |
The screw will sit flush with the end of the cap. |
Cutting off to length. |
Wait! I decided to angle the end first. Just to make it pretty. You'll notice the weird way the tool is clamped to the top slide. Well a customer had an emergency and needed to replace the toolbit clamp for his top slide. So I sent him mine and forgot to order a replacement one from Taig...thus this kludge. |
Turning the taper. Notice the groove from starting to part off and then reconsidering. This is not a planned, rather an evolving, project. |
Then I parted it off, and flipped the part around and mounted it in the full circle jaws on the 3 jaw chuck. I then faced it flat as parting often isn't perfect due to flex in the blade. |
I bored a slight relief on the face. |
All done! |
I assembled everything. It pleases me, and is a start to the sci-fi look I think the gun will end up with. |
One assembly done, how many more to go? |
