Well, here it is, my first update in quite awhile.....
I finally got my air tank finished up, still need to do brackets on the frame.....
First, a reminder of what I started with:
I welded the end caps on (mig with s/s wire) and made some plates out of 3/8" stainless plate for all my fittings, drilled pilot holes in the plates, welded them on, drilled and then tapped to 3/8" npt. Then made some mounting tabs, and welded those on too.
You can still see the air fitting and plugs I put in it to leak check it....only had one small leak near one of the mounting brackets, easy fix
More coming.......
