Here are more of my bench.
I have an LnL AP, and it is the only thing permanently mounted. It is solid as a rock.
I kept my bench from being too deep - one because I have limited room, the other because I wanted to be able to easily reach the pegboard on the wall and to keep the bench from becoming too much of a clutter station. Narrower on a reloading bench, to me anyway, is better than deeper. Seems counter intuitive, but I have been very happy with the dimensions.
On the long side, the very end that sticks out was supposed to house my filing cabinet, but I completely missed the measurement and it doesn't fit. The white bins that are on the bench top now are beneath it - I keep my brass and some towels/rags in those. I have a shelf under about 2/3 of the entire length of the long side and the entire length of the short side for storage, and where the two plastic bins are now is where my machinists chest sits that houses tools.
I've installed more shelves above the long side, and another one above the short side where I keep dies and reloading manuals as well.
Like every bench, it's always a work in progress and will continue to be so.
Framing Up:
1-1/8" thick birch/beech (can't remember which) top I got at Ikea:
Urethane finish - first two coats were satin finish, didn't like it so the last 3 were gloss. Sanded each coat between applications with 300 grit. Yes, I did not cut the corner joint correct at all. I still hate my lack of thought to this day on that one.
I added some trim to dress up the looks, and a little paint on the legs.
Short side - LnL AP permanently attached. The pegboard on this side pretty much houses anything and everything LNL related.
With the shelf added:
Long side - removable tools here, storage shelf underneath.
