RickK's 170 rebuild

[seabob4]

Rick, let me tell you, when you have stringer forms that measure 1/4"...damn, after glassing and foam filling, you could run her into a brick wall and she'd just ask for more!  Excellent, bud!

[wingtime]

Looking good Rick!  She's gonna be a stout little boat!

[Callyb]

Wow Rick, those are very impressive! You have set the bar pretty high so far with the cleanliness of your build. It looks picture perfect.

[RickK]

Thanks Cally - I only get one shot at this so....

Looks good Rick   You have some CCP stringers in that girl

[RickK]

Thanks John, only get stronger from here.

Got a little more done today - again too windy to put up the tarp - sun was smoking.
So I made the braces to keep the stringers where I wanted them


The inside is the critical spacing


The front brace was a lot of finagling, again the inside is the critical spacing


Laid the fuel tank on top and marked the places to cut it in - from the back


From the front


I decided to start the fuel tank at the back of the console and let it run forward .  I figured that with all the batteries right above the back portion it should act like it used to. We took the plunge.


Next step is to create the fill pieces to enclose the notch. Also need to build a seat for the tank - from the back.


From the front


I got overheated and had to go chill for a while. Then we decided to drill the drain hole in the transom so I don't have to bail 150 gals of water again.  Drilled it and then sealed it with one coat of epoxy.  Will sand that and put another coat on it.  The thickness of the transom core was amazing - at least to me

The dark part to the right is the transom glass before the core - 3/4", then the 1.5" of wood (we needed to drill all of this in 3 shots so the core got damaged as we pryed it from the hole saw. The portion to the left is the lams on the inside of the transom.  Total, almost 3" thick at the bottom of the hull.

Dang, Rick, you do good work!

Nice clean and good progress Rick

[Aswaff400]

so rick, with a transom that thick and stringers that beefy, you plan on hanging a 250 or 300 optimax on that transom?

maybe not... but its nice to know you can

 - I think I'm max'd at a 115 without sinking.  Sitting at idle or the hole shot on these things with a huge motor is not the problem, it's coming off plane where they sink due to the water coming over the back.

Today I wanted to build the molds and lam up the filler for the cut-outs in the stringers.
I decided to use one of bulkheads I had lam'd earlier as a mold to make the filler - it has one 90 degree side and a flat top.  I just needed to "dam" it off for the ends.  When I cut the notches I allowed 3/8" for expansion front to back (I emailed INCA for advice or installation instructions and got no reply - understand that the tank is 12 years old already but.... just saying) so I used that measurement and marked the mold.  I used some scrap Jasper board and cut them to fit.  I'll show you one end of the dams.  My intention was to build the dams with big fillets of poly so the cloth would bend easier.  I started by laying some visquene down and then taped the jasper board on the lines I'd marked and then layed in a big fillet.  Not too easy to do in a 5" spot and I only needed the 90 degree side and the bottom but ended up going up the other side just to make it transition right.






I head out to get a sandwich for my wife and I and waited for it to cure.
I popped them out and this is the dam before I cleaned it up. Before:


After:


I then taped the dam back in


I then lined the entire mold with visquene and started dry cutting the 1708 in - 3 layers. The blue line is 1" more than I need in height so I knew where to stop the resin.


This is what one of them looked like in the mold


and out - with visquene still on


and with it peeled off.  I will trim it down at least an inch in height and about 2-3 inches in depth. The stuff at the end is a little pile of the paper thin poly resin that was stuck to the visquene that I broke off and left in the corner.


Next weekend I'll pull the stringers out and grind the inside down a bit, scribe the fillers in, grind the fillers and then epoxy them in.

Looking deluxe

Looking really nice Rick!!!!   Did you see what Joel posted back on bateau about foaming then cutting the sides out?

[RickK]

Yup.  You saw my reply too, right?
