How To T-Ball Your Mast

Before starting this process, review your mast layout and spend some time preparing.


  • Use a T-Ball fitting that is the high load type. This has a lip the entire way around the opening and spreads the load better.
  • Mark the bearing point of your T-Ball.
  • Scribe the T-Ball hole allowing for the lip and cut the hole. Make it fit neatly.
  • If you're using a twist drill to cut your holes, drill the hole undersized and enlarge it to the correct size with a file to get a neat hole.

  • Once it's a good fit as seen below, drill holes that will secure the T-Ball backing plate.
  • Prepare all surfaces to be glued by cleaning with Acetone/Solvent. Mix up Epoxy with some Microfibre glue-powder until a thick paste is formed. Consistent enough so it will not drip off a paddle pop stick.
  • Apply Glue to the T-Ball backing plate. Put the backing plate through the hole and move into position with a thin piece of wire. Put a T_ball through the hole and backing plate to hold it in position while you rivet it in place. Rivet the bottom rivet first.
  • Remove excess glue with acetone or solvent.
