Another project: '73 Tsunami

[CHANCE1234]

Nice work. Did you inset bare wood and than glass it or did you glass it first and than add more once it was in place

Thanks Chance. Im really excited about the project. Ive done other boats but always wanted a 23' for myself. A few years ago I rebuilt a Sabre sailboat from bottom up which I still have. Sailboat may be on the market this spring but I am so far undecided.

The order of operations was something like this: First I ground down the inner skin which was left intact. Next I mixed up some cabosil and chopped glass with epoxy and troweled it with a 3/16 notched wall trowel. I added the first layer of MDO (after rouging the surface) and screwed two dimensional strongbacks from the inside. I then filled any voids around the edges with those empty calking guns from west system and the same filler mixed up like putty. After roughing the second transom cut of MDO, I thinned out the epoxy with heat and rolled it on to saturate the surface of the MDO. I coated both sided of ply with thickened epoxy and pre-drilled/ screwed the two together. The glass cloth you see is layer one. I just rolled and applied that on to get proper build up. One more layer and then I should be able to glass into the hull sides and fair in.

Engine beds are next and all the grinding is already done. Anyone have anything to say about using treated landscape timbers for engine beds?

more progress pics of transom tear down/build if you have them please. So your going to wrap the glass around the sides of the hull to tie it all together?

Finally... The last layer has hit the transom. This is the fifth layer of glass. All 1708 biaxial/ stitchmat combo and epoxy. I would approximate the glasswork is 1/4" thick.

In the last pic Chance, you can see how I wrapped all the edges onto the hull sides and bottom- not too much, just 3 1/2 or 4". I just wanted to tie into the sides if even marginally. I've got more progress pics- i need to get them off of mine and my buddies phones (i'll figure it out someday) easy to take the pics with my phone. PITA to get them off.

This transom is so strong it is almost ridiculous, when you knock on it it sounds like you are knocking on a piece of granite. Though I suppose it should, there are five gallons of epoxy already in the transom.

All thats left to do is fair in with some epoxy filler and we are ready to paint the hull!

Last night, my nephew, brother in law and I spent some time prepping the hull cap for fiberglass (which happens later today). Here you can see the "mold" that was created from above.

First order of business was bracing the mold from side to side and front to back while on the boat using 2x4 8' and 16' screwed thru the hull cap from above, then we pulled the cap, flipped and started grinding...







Pretty soon it will start to look the part. Pilothouse is coming along nicely as well.

looking good, any plans for a anchor hatch on the bow?

Major work! looks real nice. Keep the pics coming.....

Got glassing Sunday afternoon and finished up around 1:00 am... :-O (went out for pizza in between) Was able to glass in backing plates of plywood for the rod holders that will be fighting giants.

Mold worked out beautifully, just one strip to glass and some fairing from the top. Definately alot of work but worth it for the outcome. Took almost exactly 5 gallons of polyester STYPOL CCP unwaxed resin, lots of yards of 1708 and two 24x48 sheets of 3/8 balsa core.

Here are some shots:

Kneedeep- anchor hatch will stay as stock. That wouldn't allow me the space to mount a rod holder in the bow! ;-) I am going to replace the forward bulkead and door though.

Here are a few shots of the Nason Ful Poxy Primer and then three coats of Nason Ful Cryl II (catalyzed) single stage. Decided this was an easy paint to lay down and repair etc. Shot with a Devilbiss Finishline FLG 3 1.5mm tip. Color is Dupont Fleet line Commercial Blue.




Going with white boot stripe and green bottom like this: (boat used to belong to my brother in law)
