[Insufferable]

Thanks, I got some input from here and others. In the end, I took a bunch of ideas and did this. I used a PVC electrical conduit with a flared end, inserted it into the hole from the bottom. With a little well placed duct tape, the hole is plugged from the bottom and there is a 1/8 " gap all around. I poured epoxy down the outside, using the pvc as a form, much like Bushwhacker's rig. but the pvc is easily removed without drilling, leaving a 1 1/8" smooth hole of epoxy. I'm going to put in the brass insert bedded with 5200. Thanks again for the help and suggestions!
