JD, I don't weld either and I use 3/4" close nipples. Get a 1 9/32" Shower Valve Socket Wrench from the plumbing department to tighten the conduit nuts.
I thread a conduit nut with the points facing out as far as it will go on the close nipple, then thread it through the drum from the inside and put another conduit nut on the outside with the points facing in so they grab the drum and the nut on the inside grabs the drum. Doing it this way the inside one did not move and was pulled towards the drum so I was able to do it by myself since it is rather hard to reach both conduit nuts by yourself.
I have also done this with my exhaust, using a 2"x4" black pipe with two conduit nuts.
The shower valve socket is the way to go for the 3/4" pipe, for the exhaust I use the same procedure, but since you can handle both sides of the lid pliers work just fine.
