No. The 1-1/4 inner tube will not necessarily fit inside the 1-1/2 in tube
because of nominal manufacturing tolerances.

Subject: [TowerTalk] Small mast design - comments?
OK, I just submitted an RFQ to Industrial Metal Supply for the following:
Two 12' lengths of 6061 Aluminum tube, 1-1/2" outer diameter, 1/8" wall
thickness.
One 6' length of 6061 Aluminum tube, 1-1/4" outer diameter, 1/4" wall
thickness.
The thick inner tube will be placed inside the joint and pinned. We will use
drive-on steps at the very bottom, a mast bracket at the 2' level, and a
"guy" holding the two masts together over the roofline of the RVs.
Does this sound reasonable? Any additional tips or suggestions before I buy
the materials would be appreciated. Thanks for the help you've already
provided. :-)
Ross, NS7F
