re-visiting racks

Today I’ve been tidying up some paperwork and I came across some old cut plans for making racks. The thing that I was working on was – how much can I get from a 8 by 4 sheet of 18mm ply?

My initial rambling drawings show that I can get 3 4u racks from a sheet or a 14u rack from a sheet. But I thought seeing as I have a few spare moments I’ll draw up the cut sheet and then I thought why not actually work out what the maximum size I could get would be? Lowe and behold apparently I can get 3 5u racks from a sheet or 1 18u rack, which is better than I thought possible.

Anyway – here’s a quick model I knocked up in SketchUp, and a pdf cut sheet for making three of the racks (with lids) from one sheet of ply.
