Under construction, again. But what I've done for my reloading bench tops is used scrap/leftover glue lam beams. These pictures are the new bench they measure 3.5" thick X 12" X 96". I've taken 2 beams this size and bolted them together with 16" timber screws to make a 24" deep bench. The nice thing becides being heavy, is there's lots of meat to bolt into. This is the upgrade, I used to have a 6" thick X 24" wide glue lamb top but in the new room height was tight. Needed evey inch. Also I used Craftsman work benchs with drawers to rest the bench on top of. The drawers on the Craftsman left a lot to be desired. These new drawered benchs I think they are Kolbolt sold at Home Depot, not sure, I'll check, but drawers are on bearings and they come all the way out, rather than 2/3's.
As you can see from this picture my height problem, low ceiling. Besides bolting to the benchs and the wall, I stack a layer of bullets in factory boxes to additionally weight the top down. I'll next post my "new' and under construction casting bench.
The oil stains on the floor are because this room used to be our generator room. lived off grid from 1975 to 1997.
