Re: Installing rivets: pre-heat or cold!
The important result of whatever technique you use to drive rivets is that the rivets fill the holes with no inter-layer expansion.
I have tried using a 3X rivet gun and two different size rivet squeezers (AKA lobsters) to drive steel rivets in Model "A" frames without heat. Hole filling was uncertain, so I strongly recommend heating the rivets to cherry red.
