RCIGN1,
Where can I get some of this G10? What is it (i.e. metallic substance, composite, etc)? How do you machine it?

I'm absolutely not afraid of doing a little fabrication.
For what it's worth... I've used MDF, soaked with CA, to build a thicker spacer for the carb on my ZDZ 80 (yup, just go to HomeDepot and buy some MDF from the building dept). MDF is great cuz it's dense and doesn't compress too much, especially when soaked in CA, but it isn't strong enough to hold the threads of a 10x32 bolt.

bake, I'm sorry to hi-jack your thread... but I think this is still relevant... may come in handy for similar situations in the future.
