Hi Jack, the tubing is a polyurethane impregnated glass fibre tubing, bought is some time ago when I was building hifi valve amplifiers (needed to be heat resistant). I'm sure I bought it from Farnell but it's expensive stuff, http://uk.farnell.com/hellermann-tyton/sbs6-black/sleeving-braid-6mm-black-25m/dp/1346821 The biggest I can see is 28mm but it's way too expensive http://uk.farnell.com/pro-power-formerly-from-spc/spc14524/sleeving-insulating-28-575mm-black/dp/1000819 All brackets are made from 1/16" thick aluminium angle and shaped accordingly regards David Fry On Monday, March 3, 2014 5:54:53 PM UTC, JackRubin wrote:
