Cutting around a dash kit

**londonena** · 26th September 2015, 07:01 AM

I need to cut off about an inch from each side of the kit as pictured below. It is made of fiberglass and comes out looking rough after the cut. My first attemp was a total failure and I now have to buy another one to work around it.

I bought a rotary tool and hsed that to cut around it. The fiberglass kind of melts and I am wanting to know the best route. I foind a workshop that is offering to teach me for $36 and a install shop which will do it for me for around $20-35. Any thoughs?

Die grinder with a carbide burr, router, multi-tool with a saw blade, jigsaw... the problem is the abrasive cutting disks on the Dremel are too narrow, and the disk speed too high, meaning the resin gets heated up to the point where it starts gumming the kerf up during cutting. If you have a 3mm carbide burr for the dremel, that would also work, but buzz it into wax first to stop it loading up. You could use a steel burr, but it'll go blunt pretty quickly.

And do it outside preferably with a dust mask, you don't want to sit there breathing in silica dust.
