Trimming fiberglass

[ntrsandman]

I need to trim some glass from my rails seats. About 1/4 inch thick and about a 15 inch cut. I have read about using a saber saw with metal cutting blades, dremel tool with a cut off bit, and your basic cutoff wheels. The cuts do not need to be perfect, but close. There is some extra for practice cuts. Any Ideas? Thanks!

(I know, saber saws usually have metal blades)

Saber saw with a wood/plastic rated blade works great

Just use an axe. Kenscolors would.

The glass content in the material is extremely abrasive, so it will wear out blades fast.

Good thing you don't have much to cut.

If you're going with the rotozip, a carbide tool will hold up pretty good on the fiberglass.

Just make sure you wear a breathing mask. Glass is not good for the lungs. itchy too.

Also, you can have someone hold a shop-vac with a fine filter during the process for the dust.

Good luck,

One additional thought, when you cut it center masking tape on the area to be cut, mark line on the tape! This will give you a good solid line that you can see and helps with splintering of material. Hope that's helpful!

if i have to do big cuts (like cutting a Peterbilt truck cap in half ) i use a "dry" cut diamond blade (same as for cutting ceramic tiles) in a 4.5" angle grinder......works very fast (watch your fingers :argue: )

oh yes; dont be as silly as me .....: use a mask!!

If you are trimming a lot of fiberglass you would want a diamond plated blade, because the glass would eat up the teeth on any other blade. But if you are not trimming a lot you might be ok, but it my still wear off the teeth just a little bit, maybe.

USE a thin cutoff wheel on a die grinder :freakin_nuts: best cut for fibrerglass, and like ken said use masking tape to make your line keeps the edge clean also

Thanks for all the suggestions! Since I have access to all the cutting devices mentioned, I will try each and find out which works best. There is enough to try them all.
