The technology to join aluminium to steel does exist.

However for someone with machining and fabricating skills they should be able to make an aluminium flange to weld the IMC to. One could cut a off the nipple connector and side of a rigid junction box then shape the side like the flange then simply screw IMC or Rigid into it. After that attach it to the engine.

This is the small stick welder I have. I've also got a small MIG welder which is currently at my nephew house. I may even get a tig welder after the first of the year. Nothing big just something to do simple things with.

just having one does not mean you know how to properly use one.. much less a quality made one ... now again what are the settings and gas mix for aluminum??
 
I do believe I've mentioned in previous post in past, what I've welded is steel. I do plan to learn how to weld aluminium next year. The IMC suggestion was to suggest a safer tubing to weld on other than galvanized EMT. What was offered was options. Aluminium can be bonded to steel with a special welders. You may have to go to a welding shop to have that done. There's several aluminium frame bicycles which have steel drop outs for the wheels. I also posted a couple of videos of methods to reduce risk when bonding galvanized steel.

So IbedaYank if you know of a non galvanized steel tubing which can be bent in a hand conduit bender please tell us what it is. If you want to share with us how to fab an aluminium flange then weld it to IMC we're listening. The important thing here is to give the OP safer options to welding on galvanized steel or at least ways of reducing risk.
 


Ok this video should be the answer we're looking for. Let me apologize I made a mistake about IMC. It had been a long time since I last used it. IMC is galvanized as well. It's just stronger than EMT. There is rigid aluminium and even stainless steel conduit. IMC still would be better since its thicker and would be easier to weld after the galvanized coating has been removed. There's spray on galvanizing products which can be applied after the pipe has cooled from welding and been cleaned. This will prevent the pipe from rusting. If you chose to use rigid, hickey bending would be the best way to bend it with a hand bender.
