Thanks Jeff. I got the Harbor Freight planer. I removed the exhaust transom wood without it though. Ground around the edges then gently popped them out with a flat bar. Actually both sides where solid. The center transom piece seems to be as well so I'm thinking I'm going to leave that in as well as the newer swim platform pieces.
I think I'm mostly through with the grinding. Minus the main stringers. Cleared out the gel from the bilge. Got the wood out from the water pickups. Will have to get the rudder wood out once a main is out. Also have one of my secondaries scribed and cut. Think it went pretty well, seems to fit. Have to adjust the height and embed. All my USC materials are here now. Eric you out there? I assume you got my transmission???? |

I popped out the freeze plugs in the block yesterday so I can replace them with brass. If y'all recall, the previous owner had put a temporary rubber one in that failed on me last year causing overheating. The hole for that plug is rusty and not smooth at all like the rest. I assume it should be pretty smooth when I install the new ones. Any tips?
Thanks! |

Thanks Eric!
You refaced your deck at your house with it? I was thinking about doing the same. Mines only about 8x10 so I wouldn't think it would take to long. Probably better than sanding down. Looking forward to having a healthy transmission this year. |

Shouldn't the tops of all the stingers be straight and level? Minus any notches. If I lay a straight edge on top of my original mains there is quite a dip in them. I would think for the floor to lay flat the stringers should all be straight on top.

I now have my secondaries ready to install. First I have to CPES. Question, how long should the CPES set in before I bed the stringers? The instructions say let it dry 2 days before applying epoxy. What do you guys think? I would like to get them installed this weekend but that won't happen if I have to wait 2 days.
I also sanded the stringers with 80 grit. Do they need to be roughed up any more? |

I think you will be fine to install them this weekend as long as its not too cold and the cpes is not still sticky. I did not do any roughing up so you should be good there too.
Maybe its not such a big deal for the stringer tops to be nice and level if you build the floor like they did from the factory. With a ply floor I would think the more level it is the better it will turn out. |

I seem to have gotten the tops of my secondaries nice and straight. Going to base the mains off of that. I've based my height off of the current engine mount points. On the original mains, from the mounting points, the stingers taper down towards the stern. Strange, guess it didn't matter with all the foam. My new ones will all be on the same level.
Yes I have the warm weather CPES. Seems like it would not be a big deal since the CPES is epoxy and I will be bedding them in epoxy. But what do I know.... Saturday's high is 90. Do you all think I can treat tomorrow morning and bed Sunday? Thanks guys! Making some progress. |

CPES contains epoxy, but it also contains solvents. This is what gives it such a thin consistency, allowing it to soak into the wood. Its important to let the solvents flash off before you glass over it. You only want the epoxy part of the CPES to be left behind. |

Thanks, that makes sense. So if it's not sticky would that mean it's good to go? |

All CPESed.
My goals by this weekend is to have them bedded and one of the mains cut out, ground down, scribed, trimmed to fit and CPESed. I was going to epoxy some fiberglass to the bottom of my drainage hole before bedding. After I bed, how do I handle the drain area as far as running tape and wrapping the stringers? Go over the hole and cut out? Leave a space then come back over the wood on top of the drain so there are no week areas? Ideas? |

I glassed the drain holes just like you are showing above before bedding. When it came to glassing around them, well it was one of the trickier areas. I think I tried glassing over and then cutting away once and it was a huge PITA. Then I just used that as a stopping point for the tape to the hull, and wrapped from the top.
That trans looks sweet! I have a feeling Eric is going to end up with mine at the end of the season. At least I hope it makes it through another season... Here is a pic of the drain area. You can kind of see how I broke up the pieces in that area and around the notches. The notches are a real pain! |

David,
Wrap the first layer of glass into the drain holes as you go. Since you're pre glassing the holes, one extra layer of glass from the sides is fine. Then subsequent layers just do a half moon cutout. That's some nice look'n wood!! |

I think I left them overnight. Only really takes a couple hours to kick and be done. Looks great, dude.

On the primaries, make sure you radius the tops with a 1/4 round bit on your router. It makes wrapping the biax easier, since it doesn't like to make sharp turns. With your secondaries, they'll only get biax up the sides, and cloth over the top. You'll want to watch the tops to make sure the cloth stays in contact with the wood.

David,
Look'n great! Yes, I agree with Mike - all that's needed is for the epoxy to kick (start turning to a solid). BTW, who's patio did you have to rip up? |

Thanks guys. I rounded over the secondaries with a 1/4 inch bit and will do the same for the primaries.
Pete that was part of my back patio, since has been replaced with a deck. I have about a ton of brick as well that was half buried in my back yard. I knew it would eventually come in handy |

What do you think guys? My old stringers were 1.5 thick and these are 1.75 thick. I set my templates up so that the new stringer would fall in the center of the old stringer. So there would be an .125 inch extra on the outside and inside. Now I'm thinking I might need to adjust so that the inside distance between the two new mains is the same as the old ones. Put the extra .25 inch towards the secondaries. I say this because the starter bump in the bellhousing is about .125 from the new stringer when centered up.

David,
Kick the mains outward so you have the same amount of room for the engine. Keep in mind you'll probably end up with slightly more glass on them that what came out of the factory. Also, get a measurement between the mains and secondaries to make sure there's enough room for the exhaust. There should be because you aren't putting mufflers in correct? |

Thanks for reminding me about the exhaust! No mufflers, keeping the fiberglass tubing as is.
That brings me to another question. There was almost like a fiberglass sleeve built up around the stainless exhaust tips where they went through the hull. I probably have a pic somewhere. Should I rebuild like that? |
