Default cutting end slots in aluminum tubing



Circular saw with a thin wheel grinder/cutter.



You mean like a small cutting disk on a Dremel Tool?

That would be ok as long as the combined width of the slots will allow the
larger tubing to be clamped to the smaller tubing. I have always just used
a hacksaw, and made slots 90° apart, making the slot length about twice the
diameter of the tubing.

I was figuring on making only one set of slots, 180 degrees opposite.
This tubing is quite close fitting ( a 9/1000 " difference between inside
and outside diamters ) and will require very little compression of the
slotted end to make a tight fit, I would think.

If slots 180° apart clamps it fine, you're done. If not, more slots or
widening of the two slots are in order.

No. I meant a normal 6 1/2 0r 7' power saw with a thin grinding blade
or steel cutting blade. The cut width will be better than a hack saw
which I have found often to be to narrow as well as difficult to
control
