Next up are the sliders, lots of them. I made a jig out of plexiglass.

It set up each slider with the same holes.

This is how they slide out. Each drawer is design to support at least 100 pounds.

13 drawers times two sides times lots of screws equals a lot of effort.

It's time for the handles.

These need to be aligned precisely because any deviation would be obvious with 13 in a row.

So I made another jig.

And that turned out great.

Now it's time to make a huge jig for the holes that hold the sliders in the cabinet.

Every alignment point was indicated with a marker, one color for each side.

Then I drilled a guide hole for each.

A great thing about this bench is that its surface is sacrificial. When this was over, I used wood filler for the holes and dumped another coat of primer on it — as good as new.

Here's transfering the pattern to the walls of the cabinet by striking a sharp punch through each hole in the jig.

This part wasn't in the plan. I didn't know exactly how much room to allocate for the width of the sliders, so I added a little extra. Having too much room is far better than too little. The sliders have some freedom to expand, but not the 1/7" total that was left over. I had to find something to shim each side, but this is such an off size. Ultimately I settled on 14-gauge cold-rolled steel. This was way overkill (and very heavy), but it worked perfectly in the end, after quite a bit of extra effort.
