Attaching the mast step

Wharram seems to like interesting mast steps, and the Hitia 17 is no different. The mast as feet that lock it to the beam fore and aft and "locating chocks" that locate the base of the mast laterally. The front block also prevents the mast from rotating and the middle portion gives a curved initial contact point for the foot of the mast to hook onto as the mast is rotated up into place.

So here is the plan for the front block, I have made it a bit wider than the sketch which I think looks better and will give more epoxy surface area to prevent shearing along the glue joint.

Now the mast step doubling block and the block are epoxied on. The sequence here was fillets, doubling block then mast foot block.

The block liked to slide around particularly with the clamps on the angled faces. It took some adjusting but eventually it sat centered and flush with the top surface.

Now that the epoxy has cured it's time to make sure the proportions and shapes look right.

Overall I'd say the mast step is looking pretty good and I seem to be getting the hang of the fillets. The second round worked out much neater than the first though you can see that i need to go back and clean up some of the excess.

We're still struggling to find a free day with good weather to do the hulls, but they are poised and waiting should the opportunity arise.
