I bought a 40m old beam that needs to be dismantled. With screws out the elements do not move. Any idea what to do? Ignacy, NO9E _______________________________________________ ______________________

IgnacyTry heating the larger diameter tubing portion close to the joint while simultaneously cooling the smaller diameter portion which is telescoped inside of it. Tom H K0SN ________________________

A few years ago, I was dis-assembling a bunch of old aluminum elements that were VERY stuck together. I tried the recommended soaking in solvents and heating up parts. I didn't have much good results

Combining the pipe hitch/come-along method with heating is very effective. I have done this. K4TO _______________________________________________ _______________________________________________ Tower

I consider myself to be very innovative or resourceful, while i dont recall a time where i have faced the stuck pipes together situation, Rich i like this idea and will not forget it, i await an oppo

Since aluminum tubing is thin and it has very high thermal conductivity I question how effective this method is. John KK9A Tom Hellem K0SN IgnacyTry heating the larger diameter tubing portion close t

Yes, but even if both pieces end up at the same high temperature, when they cool the seized surface between them will probably break loose. At least that's been my experience with heating a seized tu

Since he said the elements were held together with screws I suspect that the problem is actually the hole deformation anyway.  Screws push material from one tube into the other tube, making a kind of
