Pins to weld on to oil tank ?

[Cjadamec]

I welded nails to the sides of my fire box to hold the insulation blanket to the sides. Any common nail you have should work just fine. They even have a nice flat head to make it easy to tack in place.

I too just welded nails in both of my oil tank evaporators. They're cheap and they hold well. I also cut the tin from a 55 gallon drumto lay over the nails after I placed the rock wool insulation. It made a good bed to lay firebrick on.

Hunt4sap nice looking arch and sap shack. Now from experience I can say that everything that leaves your shack out the flue stack or out the copula has to be replaced by incoming air. That air is going to come thru all those openings in the walls and if you over insulate your arch your going to freeze standing around stomping your feet.

Been looking too. I welded the stick rod to the walls and am planning to just slide the washer over that. Got special ones for cast iron from work for my wood stove kit door.

Pieces of tin or stove metal might be what I end up doing too. Got this link today and will call tomorrow. I looked for a few hours so far then someone on here sent me this link. stud.midwestfasteners.com/category/weld-pins

Bit of a dumb question maybe, considering not many seem to suggest or use them, but what is the issue with using small brad nails and some cheap washers both just tack welded?

Nothing wrong with tack welding nails to hold the insulation. It works great. You may want to step up the size of the nail just to make it a little easier to hold and weld. A common nail with a head makes it pretty easy.

I didn't even bother with washers I just bent the nail to hold the insulation in place.

used stick weld rod on a different arch. got insulation washers from an insulation contractor. found it easier to make the pins up and put on stinger to push thru insulation to the tank wall. after a bit of spark i just pull the ground and un clip the stinger. push the washer on tighter then. this leaves some rod sticking into hot area so we'll have to see how that goes. i could grind or nip off the rod too but it may just break it off too.
