... as mentioned in the other PTFE-thread, i made moulds with a high-temp 2K-silikone. With a shortcut to another discussion about virtual stone (made from sand and epoxy) i would say that a perfect replacement for concrete (because of the brittleness) and/or PTFE (because of poor thermal stability) would be a compound of sand and this 2K-silikone.

Hi sid, ... main problems here would be first: - the friction in the hoses and second: - the displacement of the winding-path on the winding-axis. For relative short ranges wouldn't be a problem, but when you want to move longer distances, then you have to wind some ten to houndred turns and the wire-coils would 'travel' along the roll, so it's not linear in tension/length and can 'overlap' atvon VDX - Mechanics
