Im new to this, but Im building my 1st board, dont know what HPL is ??, and I tried to find a local source of small amounts of ABS strip and gave up, was trying to find an easy way round the ABS rail thing and finally came up with 17 mm x 4 mm hardwood moulding which is really cheap about Ã‚Â£ 3 for 2.5 metres at B&Q, and when cut in half along its length makes a great 4mm rail, bonds well to a formica base / glass and is realtively hard wearing specially if coated with resin (Im guessing !).
By the way:
Ive laminated a 20mm thick foam / glass core the Eric H way (but not vacuumed) and it looks great but now its cured Ive just found out it flexes like a wet stick.
I thought it would be stiff
.... Any ideas what went wrong ?? I cant believe the deck laminate when added will stiffen it that much.
