It sounds like you are able to make you tanks like I am. I made a small tank 3x4x12 and then two that are 3x4x34 that way I can do small parts and receivers and also be able to do barreled FAL receivers.
if you can fab your own tank then the proper size tank will change with what you are going to cook. yes at least 3 tanks is a good start. I have found myself cooking all kind of parts now that I am set up. tools at the fd even motorcycle parts, and some parts for my dozzer. like any other tool once you have it you will find many uses for it. It works great and is prety easy to get good results. As for heavy guage,,, it sounds like what you have will be just fine. personaly I want my tank to be rigid, and I do not want it to go "TUNK" when it gets hot and warp out of shape. this could be very bad if acid were to spill out or fly when the tank popped.
I know, I know , TUNK is not a word, but you will know it if it happens due to a flimsey tank. again it sounds like you are all set.
oh yes do you have a blaster to clean with?? or are you going to do something else?
thanks for asking,
sorry to hijack this thread so I will be short. my hand is MUCH better I have what seems like a few layers of dry skin now. it is not as thick or tough as the other one. still redder that the other one with very clear line ware the red stops. it is very sensitive to texture. my biggest complaint is the big nuckels hurt deep inside. I am told they are still swolen and even that will get better. the only scar is ware I put on a glove too soon and it took the thin new dry skin back off. all in all much better. I would say about 80 % back. again thanks for the consern. the hotbarrel
