These is much better made and fit then I would ever have thought
Materials and fit to my pt-31 tourch is outstanding. One day prime delivery. Did try it and will have to make smaller wheels for the short tips, but ordered longer tips to try, I think that may do it

Big learning curve
It helps you follow a nice circle, but I went through 4 tips and 3 porcelain cups making 4 cuts on some 3/8 inch plate steel. If you do not have it adjusted exactly perfectly you'll stick and have to stop cutting and mess up your cut or you're too far from the steel and burn out the tip of the torch. When trying to make a 3 inch circle the roller wheels are too tall and lift the pivot pin off the steel and make it impossible to work right. The only way this will work good is cutting thin metal in 8 inch or larger diameter circles.
