: Hi,

: I'm ready to fasten my 1 3/8" aluminum inserts into the aluminum 1
: 1/2" outer sections to make a take apart mast similar to the Balogh
: masts. The outside part of the mast should be free of rivits or
: obstructions as I am using Sunfish sail slide rings that have very little
: clearance. I think someone told me that Balogh epoxied the insert into the
: mast but that the aluminum must be sanded and quickly epoxied before
: oxidation took place. Any ideas about this or has anyone epoxied aluminum?

: John

Hi John,
Acid etching would be best to take off the oxidation but as Mike Cluskey said, sanding will do fine. As soon as you have sanded the tubing, apply epoxy straight away. This will stop oxidation right away and you only have to worry about the epoxy setup time.

Another method is a pure interference fit. Warm the outer tube and freeze the inner one, fit together and let them reach the same tempetature. Kind of like shrink-fitting. But this method needs close tolerances to work.
