Thanks, Al! All good suggestions and I'm going to note them for the future. I ended up temporarily just putting the mast INSIDE the 3.5" OD pipe (it is 3" ID and the OD of my mast is 2.25") and it is working fine for now, but it spins in the wind (not good :-), and is a little crooked.
I ended up finding the perfect clamp at Talley which Andrew (KG6END) at Santa Barbara Electronics Supply can order for me at 1/2 the cost that I'd have to pay direct to Talley. That said, I haven't ordered it yet, so if anyone has one they want to sell, I'm still looking.

You can try back to back 'U' bolt clamps in a pinch. It'll take 4 if one of the mast is free to prevent it from tipping to one side. Fence company's have more appropriate clamps for$$. Might try Home Depot or OSH. When all else fails use some good baling wire and a large nail to form a figure 8. Do it 2 places., one shoulder high and one ankle high. For temporary nylon rope will work.

I am trying to attach a 2-1/4" O.D. push-up mast to a 3-1/2" O.D. pipe that I have cemented into the ground (my old 9-foot "big ugly dish" mounting pole). Does anyone have anything they want to get rid of or sell that might accomplish this? Old, rusted, and used is fine.

How about pulling it out, then drill and tap the 3.5 pipe and put in some setscrews? You could go big with 1/4-20. Two sets of three setscrews a few inches apart would give some pretty fine control of centering and straightness.

Great idea... thought about similar, but I like your idea better. Even better, weld nuts on the outside of the 3.5" pipe for more threads than what could be tapped into ~1/4" of steel! (Just need a welder :-)
