Wa'apa Build - Part 28 (wae, mast partner, seat, etc)

Been slacking on the updates a bit...so here's a dump of various things accomplished lately...


Leeboard support and seat were constructed and installed...

Three layers of ply are laminated and fit in position. This stiffens and provides support for the leeboard which will go here.

Leeboard support doubles as saddle for one side of seat support timber.

Seat top being coated in preparation for gluing down. Can just see the plywood saddle which supports other side of seat timber.


Comblete, ready for filling, coating, etc...


The drainage/scupper holes for cockpit were cut out. Three in total, one in each corner of cockpit except corner where leeboard support is...


Very thin (like card stock) piece of craft ply used as a buffer when cutting to avoid causing damage to floor...




The wae got a bit of edge rounding and shaping, then glued in...




To facilitate making and fitting the mast partner I made a quick dummy mast section of proper size...




Mast partner construction and installation...

Four layers of 6mm ply laminated together...good use for cockpit floor hatch cutouts...


Nip, tuck, plane, sand, etc...and we have ourselves a mast partner...

Since bolts are going through, and partner will be under a lot of force..I decided to wrap the wae in a layer of glass to reinforce and protect against splitting or cracking..just in case.

After glass cured and I determined position of partner, I marked and drilled holes for the bolts.

Then partner was clamped into position, the bolts inserted and tightened slightly to mark the partner for drilling. These are 1/4 inch / 6mm stainless lag bolts and washers.

Marks from the bolts let me know exactly where to drill pilot holes in partner to receive the bolts.

Using my drill guide jig, the holes were carefully drilled nice and true.

Extra bracing was constructed and bonded into place to help strengthen and take the side loads from the partner.

Then the partner got buttered up with goo and bolted into place. I used a liberal amount of unthickened epoxy in the holes and on the threads to protect/prevent against moisture ingress. Bolts were tightened just enough to be good and snug and get good squeeze out...but not super tight.

Once cured everything got a few coats of epoxy to seal it all up.




That's it, except for a couple tiny things, this half of the hull is pretty much completed as far as construction goes. Of course I have to get the other half caught up (would be nice to have room to do both at once...)..but that one should go quicker.

Wa'apa Build - Part 27 (cockpit floor, wae)

Focus of recent work has been to get the cockpit floors installed and start work on the other bits needed to complete the main hulls. This mainly involved constructing and installing three semi bulkheads, cutting holes for hatches in floor, gluing on stiffeners, epoxy coating, etc. 

Unfortunately the sd card in my phone/camera has gone corrupt and I've lost most of the in progress shots of I had of all that stuff...so not a lot to see this time round..


Floor glued in, epoxy coated, and fillets all around. Also 6mm reinforcement ply glued in where wae will pass through hull.

Can just see one of the semi bulkheads under the floor.

Mast step cut out...

Test fitting the wae. As well as a tie point for the iako/crossbeam, this wae will also have the mast partner attached to it.





Getting there, just gotta keep knocking items off the list...
