Don't have the luxury of building over a room (which I'd much rather do), and was going to build my own bench until I found this lovely unit at Costco.....
For unde $400, I got a rally good, heavy, smooth worktop, lockable storage for powder/primers, space to put smithing/reloading tools, dies, bullets, brass, etc. Bar chairs are about the right height, it's got heavy locking casters and moves around easily when unlocked on a smooth floor, but when locked, stays sturdy in one spot. Ample storage, lots of bench top work space, and for the price, I couldn't have built one similar for the same. Love it.
That the one I was looking at when I was in Moncton. I wasn't in a position to purchase at the time(No way to get it back to the island) So how firm is it when using the press? Move or give any? And do you have it bolted directly to the table top or are you using a plate of sorts for support?
