I'm sure this is has been covered but I can't find it anywhere. Is there an easy way to cut body tube? I build low power stuff so the biggest body tube I will be using is BT-80. I have a razar saw and miter box that I use for small stuff but it isn't big enough to cut anything bigger then BT-50. Even with the miter box I have had problems with the body tube moving in the miter box so it doesn't cut straight. What am I doing wrong or is there a better/easier way to cut body tube?
