So I have found the perfect budget build for me. We removed a Pylon sign today that had and 18" diameter 0.250" wall pipe, and managed to get me a piece of it. My goal for this build is keep the cost down as low as I can without sacrificing quality. That being said I am planning on using the 18" pipe for the FB too. The stand and stack I should be able to salvage from the steel in old signs. I for see needing to buy the plate for the RF plate and end, and misc. thermometers, handles wheels, etc. I look forward to sharing this build. I will post pictures as I have them.
