The colson wheels have a round sidewall, i suspedct the used the scraper like a lathe and flattened out the side wall.

I have used this method before to drill holes, I just would like to issue a warning to people considering doing this. You need to make sure you have a center mark on the holes, then center punch them. Using just the exterior of the hole to line them up can cause issues with proper spacing. Otherwise this is a good solution/use of cad for teams without CNC or machine tools to build parts, It works especially well for sheet metal whole locations and anything that has a flat surface. It can also be used to make cut lines on parts.
I have used colson wheels before for other applications and they are very durable, but the major advantage comes from the weight and price of these wheels, the tread is 65A durometer, similar to the wheel chair wheels.
