K&S aluminum tube in 1/2" .049 wall???

[WillyK]

Folks,

For my rail launch setup I'm cobbling together a stand-off that's built around some hobby store K&S aluminum tubing. The local hobby shop had some 3/8" OD .049" wall stuff that will work. I'd like to slide/fit this into another piece of tubing. I'm wondering if the K&S aluminum metal tubing comes in 1/2" OD .049" wall thickness. The hobby store guy didn't know, and before I start running around the city hitting different hobby stores I was wondering if anyone knew if it even existed?

The K&S web-site doesn't allude to it.

Thanks.

The closest I can find is 1/2" with .035 wall which is slightly too big for a snug fit There is a 7/16" with .035 wall but that's too small for your 3/8" tube.

Hams typically use aluminum tubing in 1/8" increments with 0.058" walls when they want it to telescope. You could use 1/2" tubing with 0.058" thick walls.

They sell lots of aluminum tubing--6 ft sections can be shipped via UPS.

Thanks Zack,

Unfortunately, ...
- they only sell in minimum 6 foot lengths
- minimum $25 order
- do not handle export orders (I'm in Canada)

If however, someone has a some small lengths (i.e. under a foot), in the .375 & .500 OD. I'd be interested in paying for it and postal costs to send it USPS!!!

Thanks though.

It is ironic that you can't find what you need in Canada--they make aluminum there--presumably next to the hydroelectric plants that generate the vast amount of electricity needed for aluminum production.
