Hi SB,
That engine is looking great with the colors on it.
I have a question: I want to create the tyres for my model teh same away as u do.
When using the circle cutter are u rotating it at high speed or slow speed.
Right now i have the circle cutters like the one u used on the Moby Dick car and tried it for the first time.
I dont have a fixed drill so it wasnt a straight cut but that can be solved.
The bigger problem was the "grabbing" from the drill into the foam and not getting a "clean" cut.
I guess using the adjustable circle cutter u might have the same problem but solved it somehow.
