I keep a G10-ruined bandsaw blade around for cutting more G10.
I cut a bunch of scales out just before I replace my bandsaw blade.

Which grit belt and speed you use ?
This is an interesting idea. Is it the normal cut off wheels for steel that you are using? Do they hold up in the wet?
Well I try ............ Just little smoke and light burn......worse become as thickness increase..........lengthwise cut better . I don't like it , for short cut is OK for long cut no it can be dengerous. I found that cutting disk for stainless last longer for cutting carbon steel ........It's micarta that I have a problem with. It wants to burn and smoke if I don't use the right technique with the grinder. I have to touch, release, touch release, because if I just press and power through the cut (like I can with G10) it creates a cloud of smoke that stings the eyes. I really need to find some googles, these safety glasses aren't cutting it.
Micarta definitely burns easier than G10. Maybe it's because the laminating layers are canvas, linen, or paper, none of which deal with heat very well compared to fiber glass. As far as cutting it goes, does no one else use a bi metal blade on a metal cutting bandsaw? It doesn't seem to dull mine.
Do not confuse the working characteristics of factory made material with home-made material. If you think material made with a wood die and hand pump hydraulic jack is the same as material made on a 300 ton press with steam heated platens, you are mistaken.
Micarta just sucks to grind. It's like Willy says, try sanding your jeans. Canvas, linens, paper they're not stiff enough to support the tool pressure required to grind compared to the fiberglass in G10. Ask any boat builder. It's not dissimilar to how a blade edge forms a burr.
I bought a full sheet of canvas Norplex micarta years ago and I only use it when requested because I just hate working with it.
G10 on the other hand, I love working with.
If you're using micarta use sharp belts at low speed. Even better, rough it out with a router flush cut bit and corner rounding bit.
Willie why not use the diamond blade on the tile saw?

I cut scales on both the bandsaw and mitre saw. I use the mitre saw when I want a perfectly straight or angled line, for example when making multi part handles. But that saw is 6300 rpm with a 216 mm blade.. It gets the job done and is faster than the band saw (18 tpi bi metal) but it sure is a little hot and the dust is all over even with the vaccum connected. It's like starting a jet engine.
I want to update my mitre saw anyway and was looking around and found that Festool has a variable speed (1300-3500 rpm) one, and also has a 64 teeth speciality blade for "hard and fibre-reinforced plastics". Saw has a little over 12" capacity. That may be something for cutting G10 and micarta sheets and scales, dust collection also looks better than on my current Dewalt (but still, dust collection is never GREAT on mitre saws..).Just a thought on the topic.
