What dremel tool to use to cut rear fender?

[FloydV]

Since I moved to Idaho and they don't have inspection stickers, I thought I would cut along the line under the license plate. It's the barely visible line that almost says follow the dots.

Question is which bit to use. Cirular saw, router type, etc. I don't want to just guess and start hacking until I find something that works.

Use the High Speed cutting wheel

I always use a zip-saw bit when cutting ABS plastic. I would suggest that if you go that route, that you get a practice piece first. The zip-saw (roto-bit) makes a very smooth cut, without heating up the plastic to the point where it melts and gets dicey to cut.

If you want to use the tried and true method, use a cut-off wheel, but watch the speed. too fast, and the plastic melts and balls up around the cut-off wheel. Take your time, and you'll end up with nice, straight cuts that will require very little clean-up in order to look clean.

I use a cut off wheel, but I leave about 1/8th" to my final shape, then finish with hand tools. The end results are clean, even and look good. Trying to just dremel it out to your final shape will result in heartache and ugly plastic.

Thanks. What hand tools? I'm thinking about files, sand paper, and maybe the small sandpaper drum that will fit a dremel.

If it is a long straight cut I use a hack saw blade with the one end handle. Slow drag, clean straight line. Better yet a slow steady razor knife along a tape edge works too. If you use a machine cut well below the line and file inward at an angle to get to the final mark. A quick deburr pass cleans up the back edge. WHen I got my current bike the undertail had been melted off with a soldering iron I think a real hack job. Just take your time for the best result and round any corners and chamfer the edgess with a fine file for that real clean appearance.

I have used a steak knife and a sheet rock knife (two Busa's) and then fishied off with a piece of sandpaper.

Good Luck but be careful, doing this mod turned me into a mod junkie!

I used a hack saw...I didn't want the plastic to melt on me...

I've cut plastic with a soldering iron before. I can imagine what it looked like

When you say file at an angle, you are saying to place the long part of the file against the long edge so that you get a flatter line?

 

[Tourbusa1]

yes, you're less likely to create a shoulder with the file and all burrs are pushed to the inside.

box cutter(straight edge razor), just be careful and take your time.

use the dremel go slow the use i low grit sandpaper and use it to clean it up will come out clean

A box cutter will do. Why make something so simple a dang on medical procedure.
