Default How to cut perfect wheel circles?

How do you guys cut such perfect cutouts? I use an ofna circle cutter and it's not enough to get it perfect. What's the trick?

Some people use a dremel to make the edges perfect after they cut it with the scissors... But since i work with sheet metal all day i dont have to i can cut a perfect circle.. practice practice practice

I use the Hobbico Circle Cutter on my sedans. It's cheap, but I've never had a problem cutting out the wheel wells of my cars.

Get some good curved tip lexan scissors, and slowly cut from the inside, while pointing the body to a light, to be able to see the marked lines. The trick is to take your time.

here is a tip that i picked up from rctvlive -

cut with scissors as best you can.. but go a little smaller than what you have to.


take an old wheel.
cut a strip of sandpaper and glue that to the wheel's surface.
put a bolt thru the wheel and then use a drill to spin it!

I mount the body before cutting the wheel wells so that I know where they need to line up. With the car sitting at ride height, I use a sharpie to mark the center of the axle on the body and then mark the front and rear of the tire through the body. Most bodies have the wheelwells stamped and so I use that as a GUIDE and cut with curved body scissors. When I have used the hobbico circle cutter, I only use it to score the front and rear of the tire. Using it to do the whole circle will make the wheel well too tall.

i saw Hagberg once, and he put the body on and wheels on. and then he cut with a regular curved scissor and cut where the wheels where. and the circles was perfect. i tried myself, but i couldnt do it haha. But i guess it needs practice.

I cut as close as I can, then use a drum sander about the same radius as the wheelwells mounted on a power drill to get the final, smooth radius.

How can you not get a perfect circle using a compass cutter like the Olfa?

As do i! Sort of... I first cut it coarsely, then i use a pen to mark or highlight the shape of the arch, and use a drum sander as TAorama does. Using a Dremel to do this makes in my opinion many small bumps in the arch instead of one nice even curve as the drum sander have such small diameter.

just use the circle cutter and score it about halfway through with the sharp blade.. then rip the lexan out. you do not have to cut through the lexan. once it is scored, then it will tear at that spot.

This is how I do it and it works like a charm. Only problem is that sometimes with TC you don't want perfect circles.
