Hey yall. I got the bright idea of doin a homemade stack and was gonna use a 6" tube out of a grain auger. i know its galvanized so i didnt know how well it would hold up against rust with the heat cycles and such... any input? :confused013: if its not such a good idea does anyone have any other ideas on what to use? haha

Thanks for any input!
-Austin :thumbsup:

I think it would be ok. Just make damn sure to use a fan to blow all welding smoke well away from the welder (and anyone else too), as galvanized stuff puts out pretty toxic smoke when being welded on.

Im not sure how long galvanized would last. For what I do for work, underground water and sewer, we never use galvanized fittings because they disintegrate in a year or two when exposed to moisture. But I'm sure if you gave it a good coat of some sort of high heat paint it would hold up alright. Just food for thought.

Thats what i was told... i think i will try it and paint it with high heat paint and see if it will holdup. Im thinking about starting it with the 6" pipe where the downpipe hits bottom. so it will be about 3 foot of down pipe then 6" to the stack

I made my own miter cut 7'' a while back. Got it from local metal shop. It was galvanized and I used a flap wheel on grinder to get it off, then painted it and primed it. Looks amazing. Dads a welder weve got the right stuff for protection though.

What is a flap wheel? im pretty sure im gonna go with the galvanized. as long as i take good care of it i should be fine i think. and i have up to 2000 degree paint! :wings:

I believe it is seamless. It is just plain straight pipe. no welds no nothing. why?

Awesome man and pumped to see it. Love stacks. A flap wheel is like sand paper on a grinder wheel. Lowes, Ace or your local metal-welding store should carry them. Youll want 80 grit. Just smooth it and paint that thing!
