I put the reloading bench to the first real test yesterday! The whole bench remained stable during the various operations, and especially when I was seating and crimping!
Unfortunately, I had to stop after a few rounds as my scale seemed to be way too inconsistent for my comfort. Probably my lack of familiarity with the scale, but I did make sure to place it where vibrations would be minimized and my various electronics would not interfere.
Nevertheless, it turned out to be a good test of the workbench. I have plenty of space to do the various operations, as long as I am mindful to only put the tools I need for that operation on the workbench at any given time. I was also able to place some plywood across the lower part of the frame to use as a storage space and staging area. The ability to use that vertical space really helps with keeping everything in a compact footprint. In sum, I'm happy with it so far!
