'Forming' Tufnol strip

Genuine Tufnol is Synthetic Resin Bonded Fabric in one of a few grades, Paxolin is Synthetic resin Bonded Paper.

Both will soften with heat, our transformer bobbin guy used to heat sheets of Paxolin over a hot plate before punching to stop it shattering.

Try boiling water first and see what that gets you, if more heat is needed then either hot oil or open flame but the stuff will burn so be careful.

Tufnol are in Perry Bar, Brum and their technical guys are quite helpful.

Only an Idea, but can you sneak SWMBO's iron into the garage for a bit

Thermostatcally controlled and temps from low to quite high wih minima burning risk.

Erm! I need to iron them round rather than flat IYSWIM.

Boiling water was only marginally effective but a brief sojourn in SWMBO's oven at 115 degrees C seems to have done the trick and, hopefully, no discernible olfactory evidence remains!

Sorry, I wasnt clear in my suggestion, I ment to heat them with th iron, and then form them around the curve afterwards, Ive had to d this recently wit some veneer I needed to steam.

minimal

:) good job it didnt catch fire... :0

It is common practice when Tufnol is to machined to tight tolerances to 'cure' the workpiece first. This reduced creep or relaxation during and after machining. A temperature of 150 degC is used - but not more as this tends to reduce strength.
