  1. Haha yeah - although probably easier at room temp with all the time in the world than squishing through a hole

    if we could get v0 + decent uv from unpigmented unfilled resin we would change to literally anything else in a heartbeat - I'm keen to learn about liquid caprolactam inmold polymerisation to nylon 6, there is a guy in Rotorua who apparently does it - he hung up on me immediately hahaha 

    The future sure doesn't feel bright in high tech nz manufacturing, just lots of losers wanking themselves about 3D printing and a handfull of actual g.c's who are getting old.

    (I'm sitting in a hotel with nothing to do hence the rambling)

  2. I've been meaning to have a play with zinc stearate - there is so little practical information about this sort of thing past around industry (in nz) looser consultants wanting to keep baby powder a sellable secret.

    are you familiar with tim scott/mr handley (Plexinate)? -he's good for a yarn about this stuff, we are currently using polyurethane/polyester mix to try and improve surface finish in closed mold lrtm process, multi-year battle. It's 2018 I just want to buy working solutions not know about these things!

  3. i cant see the context of what your meaning however liquid wax / wax in styrene solution is added (to polyester and vynlester atleast) due to it not curing at the interface with air, not as a release agent-

    the idea is the wax allways wets the surface enough to stop the air touching the resin directly, if you use unwaxed resin in open layup the open side stays sticky forever, in closed molding i have not seen a perceivable difference in surface finish with or without at the approx 0.5-1% (we) use it in

    im not very familar with epoxy - may be a diffirent story

    Diesel is just kero with extra lubrication additives added. 

    actually?

    i allways feel a little crook after using my diesel parts washer but not with kerosene, mabey its a placebo?

  5. If it doesnt pull far enough to release and you can't find the right pedal box you can get the pressure plate Finger pivot point moved at the same time as they increase the clamping force & skim it if you send it to old grumpy at autoclutch - it's the same price as buying a heavy duty excedy anyway 

    just make sure if it's the other way and pulls too much that you don't pull it much past being fully released or you will bend something
