hello,

is there a great tool for cutting the fiberglass cowl other than a dremel. i am trying to cut muffler holes and cutout the air exit holes of my cowl. need a tool that can make fine round corners.

thanks in advance for your time.

Usualy a dremel can make just about any cut you want with the right bit/attachment. Its all Ive ever used.

Use the dremel sanding drum for corners.

I use a dremel and a combination of purpose made sanding blocks for all my cowl work.
I normally do the rough shaping with the dremel and one of the sanding drums and then once I have the holes close but slightly smaller than needed I will use various sanding blocks made from things like PVC pipe, etc with self adhesive sandpaper stuck to them. A hard wooden block with self-stick sandpaper can made a nice straight edge and a piece of PVC pipe of the correct size
with self stick sandpaper can leave a beautiful radius or a nice round hole. All you really need to do is mark the openings carefully and work slowly to get a great looking job..

I don't go that crazy with it because I usually hit a big junebug or something on one of the first few flights and it cracks and starts looking crappy anyway.
