Help needed with tubes for Smitty's pens
OK, this may be a dumb question, but before I go ordering some new pen components I would like to know if anyone sells 12 mm tubes. I am considering Smitty's Cabelero kits from Exotic Blanks. However, since I am prone to messing up I would like to order some extra tubing. The Cabelero kit says it takes 10 and 12 mm drill bits and I assume therefore 10 and 12 mm tubes. I can find 10 mm tubes but only 12.5 mm tubes. I'm assuming 12.5 is too big and even if I can drill it out the components may be loose fitting. I've looked through Exotics and PSI web sites for 12 mm and could not find any. Any suggestions or help would be much appreciated.
