I do these 1/6th brake rotors and most of the need the “hub” painted which to me is a pain. So I bought the circle template

Once the circle is cut out I apply the tape to the rotor

Next I spray it all with Tamiya Fine Surface Primer (white), in most cases the rotor is chrome and the primer this helps the color stick to the chrome, this has worked in most cases for me and saves stripping the chrome.

After the primer is cured well I shoot the color

I’m also testing the insert photos in text trick…LOL 🙂

Great trick, my friend @bikequeen! Also the chrome painting technique is equally great!

i have been using a wad punch, but your method looks the better way to go.

Hmm. Seems an sensible obvious solution to a PITA problem. I use a compass cutter occasionally. Combine this with a roto cutter...😎. Thanks. Nice one.

@bikequeen - I have the same question as @gblair... where did you get that? I have a crappy plastic one myself...

Here is a photo of the templates the one on the left is heavier steel (both stainless steel) the one on the right has more hole options but if not careful the blade will ride up over the edge, once again I got them on Amazon forgot how much I paid

Hi All,
May I suggest a rotary circle cutter. A bit on the pricey side but this is one tool I'm glad I purchased.
Quick, easy, smooth, crisp edged circles with no hole in the middle. There are different manufacturers but this is similar to the one I have.
