500 gallon tank

post #1 of 14
Thread Starter 
I had a 500 gallon propane tank given to me that had formerly been used for a volume tank for a air compressor. What I am thinking is that yhis is larger than I need so I am going to cut the dome off one end , cut out a three foot section reeled the dome end back . Then cap both ends of the 3 foot piece for the fb . Planning on building a reverse flow smoker. I know this mite be extra work but since i have more time than money trying to save a few bucks where I can. Any comments advice or suggestion are appreciated . The cc should be about 83 inches long with a diameter of 37 inches the fb 36 inches long by 37 inches in diameter. First time build and new to this site

Welcome to SMF!

 

Glad to have you aboard.

 

If you go to the reverse flow build section, there is a calculator at the top to help you with the sizes you need.

Good luck!

You might consider welding the 2 rounded ends together after you cut off the end.  If you watch Aaron Franklins youtube video of making a propane tank smoker, you'll see a simple way to mark & cut the hole.  It would be less welding to do it that way.  Then you have a flat end for the firebox door end & a flat end for the plenum/chimney.

Do it once and do it right.  These smokers last years so make sure it is how you want it or you will be kicking yourself each time you look at it.

 

You may want to brace that door so it stays flat and seal the door gaps well.

 

Easier to ask questions here first than spend an afternoon grinding off welds.

I am going to trim around the door with 1/4 by 2inch strap to help seal it then brace the back of the door with angle iron to help prevent warping. I have been reading other posts for about a 6 months I have got some great info from here.
