DX Engineering should have the lowest costs. There's no chance this will work and filing the hole larger is a nightmare. You cannot slide a 1" OD tube into a 1" ID tube. You can use hose clamps on the slit ends or sheet metal screws to hold the pieces.Īll the DX Engineering tubing has 0.058" walls which allow the next size up or down to telescope without binding. I don't know where the ham antenna manufacturers get their swaged tubing from but you can get telescoping tubing from DX Engineering with/without end slits. The tolerances would need to be tight though. My other option would be sleeving 1" ID over 1" OD. Which would be just under 8 foot that would be even better as the off set between the swages would increase by quite a bit.ĭoes anybody have any links to suppliers that specifically sell swaged aluminum tubing? Or if the supplier would cut the maximum length allowed that would not require freight. It would give a little over 2 foot offset which may be enough to prevent any sagging. So my plan to save on the shipping is to use 6' swaged tubing and oppose the swaged ends. The CM-1160A is long and uses swaged tubing. The booms on the 1100 are just over 11 feet long. The basic problem is that if I purchase 12 foot lengths of 6061-T6 or any tubing of that length the shipping pops up to over 125.00.Ĩ' falls under the bump freight charges as well. I have been going to various tubing suppliers and am not have any success in locating the product. I am in the process of preparing for a full rebuild of a CM-1100.
