[TowerTalk] Pipe Cutters

[Bill Cotter]

Richard,

I think Steve's answer in an earlier post (using a file to clean 
the cutoff wheel) adequately solves the aluminum 
loading-up-the-wheel problem. A similar problem occurs when using a 
grinding wheel, and using a diamond tool to restore the wheel. Of 
course, you sacrifice the wheels, but so what. They are very 
inexpensive.

For years I have used a Delta bandsaw for cutting tubing sections. 
The fact that you have to push the work through the blade, makes 
the case for Mike's suggestion of using a cut-off saw. Not to 
mention, you can 'chop' any length, since there is no throat-depth 
issue (ie: bandsaw). A blet grinder and tapered reamer make the cut 
complete, and ready for telescoping.

And, yes, reading the manual says what to cut and what not to cut. 
I think you have to put the manual into perspective. It is written 
for the lowest common denominator walking into Harbor Freight, not 
for those who have the experience and skills to be innovative.

I just added this cut-off saw to my Christmas-request list! Thanks 
Guys!
