I see there's a blade version and disc blade version too - when looking for tools, I tend to buy the best I can afford - in my real job, cheap tools won't do!A quick Amazon search pulled up a couple, I had the off brand "HobbyLine" copy of the Olfa and it was a piece of C#@P!!! Maybe the olfa brand one is better, and it's not much more than I payed for the HobbyLine one.
A bit extreme there @zathros - I'll at least have a go with one before I resort to industrial methodsI have curved scissor I used that I got from Michael's Craft stores. I never have luck with compass cutters. I had to cut a pile of wheels, I got so frustrated, I stock a nail through some paper, mounted it on the metal lathe, and cut way too many. I needed 8 wheels, had about 40. You could do the same with an electric drill, nut and bolt, to tighten paper, and a file to form the circle.![]()
