G12 and G10 question?

[AfterBurners]

Does anyone know off the top what the thickness is of each type of fiberglass?

You can order whatever thickness you desire.

G10 and G12 are essentially the same thing, the G12 being 'fire resistant".

They don't sell G12 now, though they used to. I always used G10 and it worked fine.

G10 is laid up cloth, G12 is filament wound.

Ok,

Any suggestions as to whether or not there are some scroll saw blades that can stand up to G10? I whack a blade after a few cuts. (Blade gets dull.) I unfortunately don't have access to a bandsaw but the scroll saw allows for tighter turns.

Table saw with composites blade or dremel with cutoff wheel.

They make carbide coated scroll saw blades that would probably do the trick. I am not good on posting links on my phone, but if you google "carbide scroll saw" there seem to be a few options.

Thanks. I need to check a pack of my blades and see about the sizes. Kurt

Most metal cutting blades work fine....i.e. hack saw type blades.
I have cut many a fin with those.

A number of years ago I did some performance testing of G10 and G12 samples in an oven comparing their strength vs. temperature for the company where I worked. Their performance was nearly identical. The G12 was *slightly* better but not enough for us to justify the extra cost of replacing G10 construction with G12 except where the customer was willing to pay a premium for a *very* minor increase in heat resistance.
