plan on going a bit deeper than that. you have to cut a long enough slot so
that the hose clamp can easily clamp it down and provide enough surface area
to prevent slippage. i would plan on about double the tube diameter for the
length of the slot.

After you cut the slot use a round or half round file to take off the burrs
inside or they can get between the tubes and make it hard to get them apart.

Just received my order of telescoping aluminum tubing rods from Texas
Towers. Sizes range from 1" OD to smaller and all 6 feet long. I plan
on
using them as a collapsible verticle on the motor home. Before I start
hack-sawing away on the ends to cut slots around which I will place my
hose
clamps, does anyone here have any particular tips or techniques to do
this? I figure I'd just cut two slots with a hacksaw about 1" or so
deep.
If there's a better suggestion, I'd like to hear it before wacking away on
my expensive tubes.

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
