[se7enthdevil]

bought a few blocks of this stuff on ebay and the seller thinks its tufnol.

 

can anyone identify it???

 

here it is turned, seems to go a dark colour but the center is this yellowish hue.

Possibly Tufnol, but more likely to be Edam or perhaps gruyere.

Hope this helps.

if its tufnol it will give off a lot of yellow dust when machining and i think that after years of being used as an insulator its now banned

 

but i may be wrong

[BigNick]

it also looks like it is tufnol as its made up of cloth and the yellow resin

Hi Steve can't say I have worked with it but quite a few boat fittings used to be made of it due it's self lubricating properties and yes it definitely looks like Tufnol. Think the dust will be pretty nasty stuff so hope you have very good dust mask.

Looks like Tufnol , or possibly Paxolin a similar thing . As said resin bonded cloth used on early circuit boards and as a insulator . I have machined it in the past .

Definitely looks like tufnol. Was a poor mans substitute for Lignum Vitae when my father used to use it to manufacture ship propeller bearings.

We used it in manufacturing for jigs, fixtures and the like - you can still get it here - Tufnol Sheet - Direct Plastics Limited

yes it gave off lots of yellow dust when it was being machined and i wasn't taking any chances. i had my blue 3m mask on and two 14" fans blowing the dust away from me.

 

what a mess.
