I use masking tape. I get one go-round of that perfect on one edge first. If it's not, I pull it up and do it again. Once it is I give another wrap or two over it. Then I use the edge of the tape to cut against. Once around with the Xacto to make the line, then around and around with the razor saw. Until the very last cut-though. I go back to the Xacto for that because the inside of the tubes tend to shred a bit.Originally posted by scottluther1369
How does one cut the perfect body tube section??? No mater what I do I'm off by just a tiny bit. Is there a jig I can make to make them come out perfectly round?

Yep yep, I shoulda said, thanks.Originally posted by Micromeister
Masking tape is a nice guide if its applied over a drawn line, super inaccrate for simple tube cutting, as it stretches badly with the lightest pressure. If you feel tape is your best choice at least use one with very little stretch like magic tape or adhesive backed stripping tape (at least 1" wide). Masing tape is useful for cutting odd shapes and tapered pods where you need some give in the line. .
Definitely. And I often put a ring of thin CyA on it first to stiffen it so it sands evenly.Originally posted by sandman
Oh! I forgot to mention one very important tool when cutting tubes.
Sometimes...even the best of us...we use a mandrel, use a fresh blade...we still mess up...a bit.
For those not so perfect cuts make a sanding block with 100 grit sandpaper, some contact cement, and a flat piece of wood.
Sand your not-so-perfect edge with a circular motion going around the edge evenly to fix it.
