I finished my portable shooting bench. Two pieces of 3/4" plywood with 1.25" black pipe which screw in out for portability. I countersunk 2.5" grade 5 bolts and washers into the top of the wood. I then filled in with that wood bondo Minwax calls High Performance Wood Filler. The stuff is like rock once hardened. I went ahead and left it plain sealed with poly as plywood sucks for stains. I cannot believe how strong and stable this is. I could jump up and down on it. I put the rubber caps on the bottom as I shoot off my just refinished wood deck a lot. Yes, it's overbuilt like most of my projects but it was a lot of fun.
