To find my ideal bench height, I started by finding the seating surface I wanted to use.
I ended up settling on a 24" bar stool.
Then, I decided how high I wanted my reloading press. For my Rock Chucker and Dillon 550, a 36" bench height seemed perfect.
(However, my Redding T-7 has different dimensions, and would be better at a height of about 34".)
Lastly, I decided how big I wanted the work surface to be. I determined that 30" deep, by 48" wide was ideal. (My bench was made to be movable, as we were in an apartment at the time.)
But... that 30" depth was a mistake. I hadn't thought about it at the time, but once the work surface was framed in, the bench was too wide to pass through most interior doors. What's worse, is that the bench was made out of a door slab, so that should have been an obvious consideration!
Having that extra depth is fantastic, but it's a nightmare to move (versus the seemingly standard depth of about 24"). I have to take door frames apart, to get my bench through.
If I were to do it again (and I might have a second bench built by Crankylove), I would go with a depth of no more than 28", unless I knew the bench wouldn't have to go through a small door for for a while (if ever).
Here, you've got a shot of the bench being stripped of all reloading gear, so it can be moved out of the house. ...Nothing special, but people like pictures.
The bottom shelf is for bullet storage. Having several hundred pounds of lead on there makes the bench very stable.
