RickK's 170 rebuild

[Aquasport Commodore]

I LOVE old skool. I talk to my kid all the time about doing math that way. I tell her the same as my grandfather told me "How will you figure out something if that dang battery goes dead and you need an answer now!" She looks at me like I lost my mind Kids I tell you now days... But she holds a 3.75 gpa

How'd you like that actual math - old style without a phone or calculator  

When I was engineering school they sold some Jeff Foxworthy spinoff "you might be an engineering student if.." shirts and one of the things were "if you can solve differential equations but can't remember how to do long division". When I saw that I jotted some numbers down and and almost had to research myself how to do it! Every once in a while I'll do it by hand just to make sure I remember

Looking good Rick   Are you using the vacuum bagging system for these lams?

[RickK]

Nope, "cinder block compression method".  

[CLM65]

I guess I should have figured that out from the picture .  You seem to get the glass to conform well to the beveled edge of the plascore.  Good work!

[RickK]

I didn't fill the honeycomb on the edges this time so there is a little air at that spot.  The rest it tight.  I was more worried about how the cloth would follow the curve of the edge.
Here was the lam schedule:
1 layer 1808 against the lid and up the edge of the outer lip
1 4" wide 1808 strip along the front edge of the lid to support it better - had a cracking problem there before
1 3/4oz matt the size of the plascore to give the 1808 and 1708 a little grip
1 1708 the size of the plascore
1 piece 3/4" plascore wet out on both sides
1 1708 the size of the 1708 on the outer side
1 layer 1708 to cover it all and up the edge of the outer lip

Should be stout as can be.  Took every bit of 50oz of epoxy to lam it up.
I just removed the blocks and plastic and it's looking pretty good.  Weighs about 10 lbs now.

I that how you do that?
I have forgotten how to do math without a phone or calculator :!:  
Looks great Rick.  

I could loan you a slide rule...

I wish I could find mine. Got the directions though.

Oh man, with all the overbuilding, is that boat going to float or are you taking on the navy as it is a battleship     Looking good

[RickK]

CB, no wonder the missus is squawking at you for being a pack rat - not 1 in 10 people remember what one of those things are yet you still have the books on it - go figure  

86 - you're right, maybe I do have a tendency of over building  

Anyway, in Carl's name I completed grinding today  

[RickK]

I added some backer coosa where the swivels will be for the front wood on the front side of the casting deck

[RickK]

Then I hoisted the casting deck into the boat to see how it fit  ----  drum rolll




 

[RickK]

It's about 1.5" short all the way around, 'cept the front




Based on how the casting deck is sitting, looks like I raised the deck about 4" in the front of the boat    Didn't seem to measure that much.

[RickK]

Well, I would reckon I'm not done with grinding either

It looks like you may need more caulk.
