Got it! I took bits of some of the suggestions: Using a forstner bit, I drilled out a cavity in a small block of white oak sized to fit over the pad on the screw part of an "F" clamp and epoxied a short piece of 3/16 brass rod in a hole through the block. The brass projected about ¼”. I epoxied the block to the pad. I didn’t make the rod any longer to reduce the possibility that the clamp pressure would push the rod over or come loose entirely. I wanted to move the wing nut enough to get some purchase on the bolt head.
I was able to move the nut about 1/16” and thought that I would able able to grab the bolt well enough to get a vice-clamp on it. I tried to get it to move a bit further, but when I put more pressure on the nut, the rod separated from the block.
It turned out that the bolt was a carriage-type and I was able to get a purchase on the square neck just behind the head using the “Jam-Bar”. I have no idea where that came from or any memory of having used it before. While picking the v-g off the tool board, I noticed it only because I had removed a couple of tools from the peg in front of it for a different job.
A little heat and the block came off quite easily.
My apology for not replying to the reply posts more quickly, but I had to deal with a little plumbing emergency first.
Thanks for your help. Now to find a length gauge.
