Hi folks,

This is a general question regarding the strength and rigidity of a wet layup. Would there be any mechanical difference in the finished item using fewer laminations of a heavier weight glass than more of a lighter weight, i.e. 3 @ 200g as opposed to 2 @ 300g.




Cheers, Marty

Hi Warren,

Thanks for that.  The tail pylon section is about 500mm long and the OAL of the model is 1840mm - see attached. 

I've done another pull of it yesterday but laid a 50g twill down first. It's so thin that I could check for air pockets even though the resin was tinted. I then let this tack off for an hour or so and then followed up with one 100g and three 200g layers alternating their weave direction. I had a gentle heat on (70*) it for 8 hours The finish is perfect but it still feels a bit flexi? Might do one in clear resin and compare.

Cheers, Marty
