Boot cowl trimming

[cposer]

Looking for some suggestions as to how others trimmed the forward edge of their boot cowl to 3/4" without damaging it. Thanks

Dremel tool with plastic cutting disk. Flawless. I beleive a metal cutting disk works as well. Im not sure they aren’t the same thing honestly.

I just trimmed my wingtips with one of those, and agree it makes a good clean cut in fiberglass. It helps to mark your cut line with blue tape.

Thanks, I'll pick one of those up.

6” angle Grinder. I find it’s the easiest for me to keep straight lines.

My cowls came as two pieces (top and bottom). I ended up cutting both of them to make them into separate boot and engine cowls.

I used a Dremel tool, made an aluminum guide that I ran along an edge I did out of pink foam. After determining where the cut needed to be I put the blue tape on the cowl. Next I positioned the pink foam to create a lip to run the Dremel bit along the cut line. It was easy to cut a straight line by running the Dremel down the guide. I used my narrowest bit as a router.

Maybe you could do something like this with a cutting wh eel and homemade guide. I unscrewed the plastic nose piece of the Dremel to mount the aluminum home made guide. I made a hole in the aluminum the size of the Dremel nose and and mounted it on the Dremel using the threaded nose piece. Then I put another piece of aluminum with a small hole for the bit to come through. When I installed the bit I made it so I just came through the hole.
