In reply to DaveHK:
Looks pretty versatile, but better suited to campusing than wider spaced symmetrical deadhangs, which tend to be the meat of most fingerboard training programmes. So I'd keep this one and build another, really simple: 80-100cm wide with just two horizontal strips of 30mm and 20mm depth going the whole width. You can use small mobile blocks of wood which you simply place when required on the 30mm strip to reduce its depth to 18mm, 15mm, whatever you can hold on to. Also add maybe a 40mm deep strip with slopers of various degrees cut/rasped/sanded into it; I found that doing pull-up sessions on slopers rather than using a bar was very effective.
PS just noticed that you don't have room to expand, so maybe just replace the 2nd and 3rd lowest strips with 20mm and 30mm going the whole width of the board, and put the 40mm/sloper rung right at the bottom?
