[TowerTalk] 3" Boom Joints

[Dan]

Andre: I had the problem of repairing a 57 foot 3" boom which had 
buckled. I removed the damaged section. I measured the ID of the 
undamaged tube and went to our local aluminum supplier. They had an 
aluminum pipe(not tube) which was just right to slip inside the boom. I 
have also had success using a piece of  3 inch irrigation tubing to 
connect sections of the same material. I cut a slot lengthwise in the 
splice tube, compressed its OD and slipped it inside the 2 pieces. You 
can use a piece of wood to drive it in.
