Fire Piston

EA put up a few threads about fire pistons. In answering his question as to why I didn't have one, I just didn't - no particular reason. Then when he posted the videos of making one, I thought - I could do that.....sort of.

Materials list:

1/2" copper pipe
1/2" copper end cap
1/2" dowel
#8 rubber o-ring
scrap wood

I cut the pipe and dowel, made the slot for the o-ring with a file, used a 1/4" drill bit for the recessed end.

We've been getting some pretty impressive afternoon thunderstorms lately. Here's the view from outside my workshop while I was working.
