I built a tool rack a few months ago. While I did a lot of lay out and measuring, the rack was not successful. The angle the tools were held was too shallow so they were prone to fall over knocking all the other tools off the rack. First time was funny. Second time, not. The tools are too close together so now I have to alternate space them.
I found that I like to have everything on the rack -- tools, finishing supplies, measuring devices, rags, knockout bars, centers. But the current rack doesn't have that much space. Probably means adding a shelf.
What does your's look like?
Thanks,
Burt
