Re: 1974 Ebbtide Restoration

I set out this morning to remove the bow section. I finally got tired of thinking a started cutting. I cut out the port console and figured that getting it out would allow me to see how to get the rest of it out. I just started tapping around and could tell where the PB was so I could just cut around it. I got it out in three section as you can see minus the floor. Hopefully I can get the floor out and grind off the wood which will allow me to keep the floor section. Then I can re-assemble everything. That's the plan anyway. So hopefully I can get the floor out this afternoon. After that, I can start grinding.

IMHO, I think you did an Outstanding Job. I see nothing in your pics that won't be easily reassembled when the time comes.

Thank you sir. I'm looking forward to that part (somewhat) but we'll cross that bridge when we come to it. In the meantime I gotta do some more grinding. Fun, fun, fun. That front floor is quite a challenge. There is one spot right where I kid you not, the resin is 2" thick. Geez

Good luck with your rebuild. I hope those materials serve you well. I'm anxious to see the stringer panel in action.

Depending on where and what it is you may or may not have to grind it! Post up some pics of it so we can guide you on how to deal with it. It might be a "Hurry Up It's quittin Time on Friday" kinda thing!!!!!!

Will do Wood. I actually have today off and planned to knock out a bunch of work over the 3 day weekend. However, I have come down with the crud, not sure if it's the flu or not but I have no desire to get much of anything done at the moment.
Jason, thanks. Yep, I hope to put those materials to use as soon as i can.

Re: 1974 Ebbtide Restoration

When John Lennon sang "Nobody told me there'd be days like these" I'm pretty sure he had been grinding.

I guess all things considered, it's not that bad. I had a three day weekend and had hoped to get a lot more done. However, on Saturday, after about 2 hours of grinding, I developed a scratchy throat and thinking it was fiberglass, I went and bought out a new respirator. Did a little more grinding until I had to quit. On Sunday, i felt something coming on, and by the evening, I was laying on the couch. So I lost Sunday evening and Monday to some kind of virus. :mad-new:

After work this evening, I went out and did some more grinding and managed to get this:

to this:

As a bit of information, I had some HF 25 grinding pads. I also had some 25 grit pads from lowes. My observation was that the lowes worked MUCH better than the HF disks.

Re: 1974 Ebbtide Restoration

Re: 1974 Ebbtide Restoration

I have a couple of questions.

I purchased about 6yds of 1708 from another member. This has 3/4oz mat attached to the one side of it. Can I use this for the stringers in one layup? What are the implications of having the mat attached. Does that prohibit me from doing multiple layers?

My transom appears to be made of two 5/8" laminated together as opposed to 3/4. I'm afraid that if I went back in with 3/4", that the extra width would cause the cap to not fit correctly at the back of the splashwell. Should I go back in with 5/8" or can I make the 3/4" work as I don't think I can find Auraco in 5/8" sheets.

Thanks in advance.

Re: 1974 Ebbtide Restoration

I like to use a layer of CSM prior to the 1708 as extra bonding assurance. Some say it's not needed. Up to you. When using Poly You always use some CSM inbetween layers of Cloth...Always. What was the total thickness of your original transom..Glass Skin and ALL???

Re: 1974 Ebbtide Restoration

Re: 1974 Ebbtide Restoration

I'm showing it to be 1.69" or just under 1 3/4".

Re: 1974 Ebbtide Restoration

How thick is the existing skin of the boat?

Re: 1974 Ebbtide Restoration

Re: 1974 Ebbtide Restoration

I drove in to work so I can't check it at the moment but as a guess I would say it's somewhere between 1/16th and 1/8" (closer to the 1/8 side).

Re: 1974 Ebbtide Restoration

Re: 1974 Ebbtide Restoration

Based on what I'm hearing you'll be very close. You might use a router to rabbet an edge on the top of the transom to ensure you have enug leeway to build up the glass for waterproofing but still allow the cap to slip down and over. It's just a matter of "Doing what ever needs to be done to get the job Done" Use your best judgement.

Re: 1974 Ebbtide Restoration

Re: 1974 Ebbtide Restoration

Gotcha. I like the idea of going back in with 3/4 instead of 5/8 and just bringing it down to the desired thickness. So is the Arauco plywood acceptable for transoms or should I get some marine grade stuff?

 

[Woodonglass]

Re: 1974 Ebbtide Restoration

Re: 1974 Ebbtide Restoration

Aruaco is some GREAT stuff. Used here on the forum ALL the time. Once it's encapsulated in resin and glass it'll last for Decades!!!!

Re: 1974 Ebbtide Restoration

Ok, that's good to know. My local HD has it for $40 a sheet.

Re: 1974 Ebbtide Restoration

Re: 1974 Ebbtide Restoration

Using a 1/2" or 3/4" round over bit on a router might take enough off the forward top edge of the transom to allow the cap to slip back on too...
Added benefit is that it should help roll the fiberglass over the edge of the plywood when you're glassing

Re: 1974 Ebbtide Restoration

Re: 1974 Ebbtide Restoration

Thanks for the information guys. I have a feeling that one way or another, a router is going to come into play when trying to get the cap back on. I haven't really taken a good look at yet but I was thinking that I could take some measurements and determine if it will fit or not. If it's too tight, I'll shave some off of the transom and fill in the rest with PB... But we shall cross that bridge when the time comes.

For now, I'm just grinding. I have committed to putting in time every evening. It's about 25 degrees here tonight but i managed to get about an hours grinding in. With the suit on, it's not too bad. I started disassembling the starboard side storage shelf (not sure what you call that) being very careful not to put another hole in the hull and I see now how to separate the remaining strip of flooring from the hull. Things are starting to move along. Can't wait for Saturday.

I'm going to post a link to a really great (IMHO) thread just so I have it in here somewhere. It has all the usual suspects.

Re: 1974 Ebbtide Restoration

Re: 1974 Ebbtide Restoration

I put in a good 8 hour day today. I got the remainder of the floor out, ground the front and sides flush down to good glass and managed to get all the foam out. I found that a hand saw and crowbar allowed me to get it out in big chunks. I just made cuts along the stringers down to the hull and then made cross cuts about every 8 inches. Then just pryed that section out with the crowbar. I may try to start on the transom removal tonight if I can find the energy.

All in all this boat really wasn't in too bad shape. The rot was pretty much isolated to the rear. They did a fairly decent job of glassing in the stringers. The strange thing was that in two spots, one more aft and the other more stern, they simply cut of about a 4" section of the glass and had a raw plywood strip running from side to side across the stringers. I'm not sure what the purpose was but this exposed the stringers. Couple that with screws in the deck for the chairs and other things, water got in there and caused the damage.

So what is the consensus of screwing things to the deck. I assume it would be ok if it was sealed but I'm sure over time, that it would leak. What is the best way to fasten the seats to the deck?
