Well, I must admit, much of what I know about modeling I learned from others on this site, and I've only been a member for the past 2 months. Anyway, I'm glad I could be of assistance.

Sully,
When cutting or sanding resin is is best, if possible, to do it under water. That may be difficult when sawing, but try to wet sand resin.
I know the first time I had to cut off a big pour plug on a resin kit, I went outside with my Dremel, a couple of cutting wheels and sanding drums. Boy, did that put a ton of dust in the air.
I found a good way to wet sand resin. Get one of those cheap plastic picture frame boxes, I got a 9" x 12". Use double sided tape and stick wet or dry sandpaper to the bottom.This is usually available at an auto parts store. I got 220 grit. Put water in the picture box, enough to cover the bottom, and sand away. Be sure to put the whole thing on a sturdy surface.

I bought myself a belt/disk sander last year it has a hookup for a vacuum hose . So Ibought a cheap vacuum fo when I'm sanding or shaping.I keep the nozzle nearby when using the dremel and it draws in most of the dust.
