Other lexan vs. optix

[Pablo]

I'm for sure not a composites guy and claim to know very little. For those that are:

I made my last TL mount plate out of what I thought was Lexan 1/4" thick polycarbonate. Does anyone know if the Optix version of the same stuff is as durable? It's listed as only a 1/10 as strong as lexan, but didn't know if that refers to shatter resistance or what. I'm want to redo my TL plate this off season and can't find Lexan local, but can find the Optix. Lexan is stated as 250x stronger than glass, where Optix is stated as 20x stronger. I have it mounted against the bulkhead above the FFH. I try to buffer the plate with rubber grommets between the mounts and the plate and use large diameter washers on the front side to lessen the stress load on the mount holes.

I have Lexan plates at my house right now... I think Shane used one of these for his TL backing plate but I can't remember for sure.

lexan is a trade name for polycarbonate

what your looking for is polycarbonate sheets, so long as it says its polycarbonate you should be good

you will soon find out if its not polycarbonate cos it will crack

i just googled your optix stuff, its acrylic.... thats the stuff that will crack..

Lexan is different from your typical poly sheet, Lexan can be sheered and bent easily and your typical poly sheet will shatter and crack but not at bad as acrylic.

I used mcdog's scraps to make my TL plate last year, but wanted a fresh piece to fab my own how I wanted. I didn't think bout mcmaster for the lexan. I assumed the optix stuff was crap for this application. I found a 30"x30" piece on fleabay for $20. Thx for the heads up boys.
