Got rigid polyurethane foam...

for free! The guy that produces rigid PU foam gave it for free, because the block was cracked, i guess for shaping the holds will do! There are 2 densities of foam i got, the 40kg/m3 and the 100kg/m3.

Above there are the first 2 shapes i did. Don`t know yet which foam will give the best friction, we will see...coming soon!
