Okay, I'm starting to understand. I thought those fibers were just the glass exposing itself as I ground off the resin, thinking that the glass would go slower than the resin would.
Darn - I was so happy about 15 posts ago when I was "1/2 done" . I tell my self - I love to grind, I love to grind, I love to ...... |

Seth,
I happened to be talking to Greg by phone yesterday and the conclusion was I need to go visit my eye doctor for a new set of glasses! Yes, do some more grinding untill you get closer to the matting/cloth in your hull. I went back and looked closer at your pictures and you have spots with quite a lot of resin on top. The resin is simply a glue to hold the fiberglass together. It's the glass that gives the hull strength as the resin is really pretty brittle. |

Is this more what we are after???
EDIT: the first one any way. It's so much easier for me to see it here in a photo than on the boat. ME thinks it's a pretty picture here - but a lot of grinding back in reality...... |

I agree with Pete.
I would think that Seth should be able to lay a nice mat and epoxy mix for the Stringer in that 1st picture. Will want to lay a well soaked mat under that stinger to eliminate any voids. |

Greg, get those glasses everytime Insurance will pay for a pair.... That way you have a pair at work, in the house, in the garage, and in the shop.
And Eric will thank you for it... |

You're so bad Roger! LOL
Seth, I think you would have had a good repair before...now you'll have a better one! There's also an OCD quotient to be factored in. The dust will tend to hide what you're looking at; if you haven't already, give the area a good wipe down with a wet rag. I actually rigged some scrap gutter under mine so I could rinse it out. |

I just went back through the thread...did the stringers have glass under the cradle?
And cool fitting on the front of that port exhaust manifold! |

Greg,I'm surprised that with the shortage of rain you had when you were doing your boat,that you just didn't take one off the house Up here we just wait until the 2 foot ice dam removes them |

I now have all the pieces glassed together and put in the primary today.
Have a question, I have glassed the primary to the hull. Should I wait until that is curred to start the fillet? Do I need to wait for a cure at every layer or can I put it all together in the same day. The layers will be bond to hull, fillet, three layers of glass. I've never worked with fiberglass so any help would be appreciated. Cheers |

Seth,
Very nice work! I see some of Greg's methods have rubbed off on you with radiusing the edges. It does make it easier to lay up the glass. No you do not need to wait for each coat of epoxy to cure. Just wait for it to "kick" (set up). Acually, it's better to keep going because with just waiting for the kick, you will get a better bond. The feeling is you get more "chemical" bonding rather than a mechanical bond after the complete cure. |

Kapla - thanks.
I used #1 doug fir. I found a local mill that dries their wood to 8% then mills it. That way when it's all layed up it wont shrink and pull away from the glass. It was a lot more expensive than the construction grade stuff but worth it, I feel. I am planning on refoaming. I know it's a bit controversial but I have a young son and I think that the safety of floatation foam out weights the down sides. We'll see. I'm going to use ply in the front and glass the floor in the back - original. Cheers |

Seth, Looking good..
A comment on the foaming. I poured foam and then tried to cut it down close to the stringers using differnet saws. Could not get a clean cut. Gouged it and had to do some over. The saws bowed. I found that if I cut it down with the saw to about 1/2 above the stringers and then used my Beltsander to sand down to the stringer tops. I ended up with a nice clean finish with no gaps for water if it ever did find its wasy under the Glass and Floor. |

Along with what Roger said, I found a jitterbug to be the tool to get it close. I also used a belt sander, but it doesn't have a full surface bottom and wants to clog. For the final touch-up, use a straight and square 2x4 or the like and glue 60 grit paper to it...makes an excellent screed!

For leveling longer surfaces, I made two aluminum angles than bolt to the sides of my belt sander flush with the belt surface. Starting with the high spots then you can get down to the level of the stringer tops. The only problem as Greg mentioned you can't get into tight spots. A couple lengths of angle would help.
The 2x4 with the 60 is probably just as fast! |

Talk about me over-engineering things?
After I saw how the screed worked to finish up the first side, I used it for most of the other. If the foam is poured in borderline low temps, it would't work so well. |

Thanks everyone for the tips and encouragement. I'll try to remember the sanding tips for when the time comes. Currently I am only half finished on the stringer part. Got 2" glass tape on both main and secondary on the drivers side yesturday. I have the next nine days off. I think that after I get the 4" glass on the drivers side there will be enough rigidty to the hull to cut out the other side. Hopefully I can accomplish this and get them back in by the end of the month. The weather is starting to turn nice and my wife and I are getting anxious to get on the lake.

Well, I ran out of time before the snow hit the ground. I have all the stringers in, but that is it. I should be moving it to a heated garage in Feb and will be able to resume the work. Right now I'm working 90 hr weeks - no time for the restore

Well I'm back at it.
All stringers in with CPES, couple of layers of matt, fillet, 2" then 6" then 8" e-glass tape. Still have to finish some of the 8". Question - Should I do more than one layer of each or do I need to double up on the 6" and 8". Plan on final one or two layers of Biaxial on mains. |

Looks nice. I bedded the first main on my 82 today. Does not look as nice as yours yet, but I think it will look much better when the fillets are in.
I plan to use single layer of 2,4, 8 tape. Couple of layers over the top. FWIW. BKH |
