Mast Joiner 11.1mm Groovy

Mast joiner – for GROOVY mast section. Aluminium.

When using mast/boom spar joiners

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

Take care to protect the track with a plug from the resin before bonding.

Use normal 24 hours epoxy resin, thickened 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, then use solvent to clean off the excess resin from the joints. Check alignment again before allowing to fully cure.
