I posted a question in the bellows section with no responses. Specifically about how champion forges and blowers were linked back in the day. I will pose a general question on what folks use to link their blowers to their forges. So how do you do it? Pics welcome please.

3" regular stove pipe that clips together lengthwise with the swivel elbows.

 

This I use for my Champion blower and cast iron forge for demonstrating.

Stove pipe with a 45º elbow.

 

The coolest one I've ever seen was a guy that took sheet brass (the thin stuff) and rolled it into piping.  The elbow was made from copper and really hammered to look rough.  It was a sexy combo - kind of steampunk and kind of retro.  And it did the job.

I actually burnt the galvanizing off (outside the shop) before I used it so it wasn't so shiny and new looking

flexible aluminum dryer exhaust hose.

That does sound cool.

Ditto on the dryer hose. I think I got 3", squeeze down to fit on my blower and hose clamped in place. Forge end is an appropriate sized coupling clamped to the hose and a jam fit onto me forge. (I disconnect the hose to put the blower inside when I'm done).

I have flexible exhaust pipe from the days it was still legal for cars.

Use stove pipe and hose clamps to squeeze an exact fit. Drill, cut then pop rivet any tapers you need. Outside diameters are easy. Rivet these first. Inside fits to flex need to have the overlapping metal cut away and be fitted before drilling to rivet. But sloppy is OK. Truth is: That air don't care. Just get it there. Consider PVC if it's away from hot stuff
