Post your "Things I have to change to conform to the new rules" list here

I've bought my helmet but I got a SA2005. At my age I probably won't need one for more than 5 years more. I haven't looked seriously at the head restraints yet but I heard you have to go to a 2" shoulder harness. Sure hate to throw away my custom Autopower 3" shoulder harness for something smaller so I can spend a bunch of money on a restraint that is going to increase my cockpit exit time!

 You still need three inch belts. The two inch belts are made on top of the 3 inch belts to hold the Hans device.

Lexan cuts just fine with a regular jigsaw blade. Polycarbonate that is not Lexan will split and crack.     vic

Lexan is just a brand name for polycarbonate. They are the same. Wayno

After reading my post, I thunk. Of course you can have polycarbonate that is not Lexan. Krusty, have you had a problem with another brand of polycarbonate? Wayno

Wayno - Ya got me, I've only used GE Lexan in the windshields, rear windows, and side glass I've installed. What I really meant to convey (ya know, "in the spirit of" ) is that you should be careful of getting an inferior quality PLEXIGLASS product, which will crack and split (and wound you). My experience with  polycarbonates other than GE Lexan is non-existant.  Thanks for getting me straight.      vic

polycarbonate has many good brands
Plexiglas is acrylic and I wouldn't use it for anything
makrolon (with the ryno) is another good brand of polycarbonate sheets

I need to replace the wind screen on my roadster and want to use lexan instead of the plexiglas that's there.. I think I read on this site, that lexan is blue when viewed from the edge and plexiglass is clear or is it the other way around?  Trouble is, my memory is mostly gone. Appreciate any help.

Re: heat forming Lexan....I seem to recall someone telling me you have to heat it for a while at below 180 degrees to get the water out of it, first.  If you heat above that, without preheat process, the water will boil and form bubbles.  Probably some info somewhere on the net.

  Jim, water?  I wonder if that is for making a tight like 45 to 90 degree bend like a flange?
  It's my understanding that a good, even heat source like a couple of heat lamps will do the job.
  I have no experience but it sounds like a few others posting have.           Bob

That is my understanding also. Wayno

[Ron Gibson]

Me too. The way I understood it was lexan absorbs humidity and if heated to quickly the water vaporizes and makes internal bubbles which would ruin your lexan. IIRC it take quite a while to expel the water. FWIW I would do research before ruining some expensive lexan.

Just my $.02

Here is site for pre-heating lexan before bending.   http://www.portplastics.com/architect/page22.html

If one chooses to replace side windows on an ex cab pickup with a polycarbonate how would you attach them? Tabs inside the body and screw or pop rivet them?

That will work just fine,,, we used 1/8" pop rivits... you can also use screws.

are you allowed to "bed" the window and not violate "sealing & taping" restrictions?
