When using mast/boom spar joiners

Prepare alloy tubes and joiners by cleaning all matching surfaces with solvent (acetone, alcohol).

Prepare carbon tubes and joiners by thoroughly abrading and cleaning all matching surfaces with solvent (acetone, alcohol).

Use normal 24 hours epoxy resin – thicken as necessary to prevent the resin from draining out of poor fitting joints before curing – and ensure the parts are correctly aligned during cure.

Simplify cleaning by allowing the resin to partly cure – between 1 and 3 hours depending on temperature – and then use solvent to clean off the excess resin from the joints. Check alignment again before allowing to fully cure.

Carbon tow wetted out with epoxy resin should be wrapped around the joined ends of the tubes for additional reinforcement in highly stressed spars.
