It could work fine with inexpensive minor modification. 1st, go to your local tire store where you should be able to talk them into giving you a damaged wheel/ rim. 15/ 16 inch preferably. Now go to your local Lowe/ Home depot store and purchase 2 sacks of qwikcrete, pre-mixed concrete. Now. on a piece of plywood, sheetrock or heavy cardboard, take your bench stand, remove the top , set the wheel over the stand pipe with the deep dish side up, mix the concrete according to directions, and fill the wheel level with the mixture.
I am typing this on my coffee table that is made from a manhole cover bolted to a 4" steel pipe that has a flange on one end and the other is fastened to a 4X4 X frame mounted on casters and tastefully painted to match my decor. It weighs 216 pounds. I use it for reloading my handgun and small rifle ammo also.
