Hi STR,
Thanks for a very informative sub-forum. What tool do you normally use to cut the G-10 after tracing the outline of the scale? Do I need a bandsaw to do it? I currently own a Dremel and an orbital Jigsaw. Will these be sufficient? I might do it as a hobby as well so the getting the proper tool to do it is no problem, as long as it is not too expensive. Thanks.
 
I have two bandsaws and either one will do it fine. I use the smaller $99 Delta I bought at Lowes for Micarta and Wood cutting and my floor model 14" for my titanium, G10, and metal cutting since its set up with a bi metal band saw blade most all the time. You will dull a regular band saw blade pretty quickly cutting G10 since there is so much glass in it but it will work. If you get the cheaper saw it will cut it with the right blade but I've found that the blade tends to drift more on that smaller saw so I much prefer my bigger one for precise jobs. I wonder sometimes if I just got a bad saw with that smaller one but I did get that one for my wife and don't use it as often. Its night and day for quality difference though.

Also, G10 dust is particularly caustic and can cause serious lung problems. Don't even cut G10 or G11 or work it to where a lot of dust is coming off it like when it is sanded without first getting proper lung protection via a good respirator with proper filtration for that particle size. Those glass fibers on any of the glass filled resins and polymers can seriously damage the cells in your lungs over time if you make a habit of working it without protection.

For that matter some of the other dust producing things in an enclosed space can be problematic also so get a good respirator if you don't already have one and of course safety glasses and some kind of vest or something that can cover the front of your clothing when working this material is also good. I use a shop vac on my band saw when cutting G10 or G11 and also make sure I turn on all the suck fans to ventilate the shop as best I can.

Finally. A scroll saw would most likely cut G10 or G11 fine but these to me are a lot more effort for the more precision cutting. The one thing I hate about them is that if you let up on the hold for half a second you end up with a lot of slapping on the surface of the table or a broken blade and it just slows me down. I have a scroll saw and a fairly good one but hardly ever touch it these days because a thinner 1/8" band saw blade or a good bi metal in a 3/8 size can do the same job but not as precisely. The G10 works very well with a dremmel and a 1/2" drum but again the dust can be a problem so its best to limit the sanding when I can being that I have asthma and have had some bad experience with the dust anyways. I buy my G10 in 1/8" thick sheets from Sheffield supply to aid me in reducing the amount of sanding I have to do on it. It also eliminates some additional cutting or ripping to make thinner sheets myself that way so you might look into that as well.

Thanks for stopping by my forum and asking and for the compliments.

Ooops. Double post. Damn enter key got hit twice there. I can never figure out how that happens when you are supposed to have an automatic one minute between posting thing on these forums.

Sorry.

Thank you so much for the info STR. I'm glad I asked the question since I didn't know that cutting G-10 is not very good for your health if you don't take the proper precautions. I don't think I have a workspace that can handle the fiberglass dust. I'll probably start with woods for now and leave the G-10 work to the experts. Thanks again.
