1960's 13' MFG carefree Rebuild (complete noob, i know nothing about this!)

Re: 1960's 13' MFG carefree Rebuild (complete noob, i know nothing about this!)

Thanks Boat ...... I started with 2 gal of Poly resin ( make sure that you use the resin without wax or you will have to sand between coats ) because I thought that all I had to do was change the transom. Along the way I found out that my keel was rotted as well so I had to repair that and order more resin. I will have to check and see how much I used all together. One thing that I noticed is that you only have a main stringer. I have a stringer on either side of the main one so you may have to add those to your boat.
Here is what my stringers looked like and they are made of aluminum:

They were bolted to the transom and to the hull with bolts coming thru the keel:

I will definitely take your advice. The only way i could get the rotted wood out of this keel would be to use a plumbers snake or something, then it would have to be totally filled with seacast... Definitely not worth my time. It would probably be cheaper to grind the keel away and totally replace it. The more i look at this boat, the more problems i see. I can count like 5 patch jobs in it that are really rough, i'd rather not work on something that has already been worked on numerous times;Improperly none the less. Its a pretty neat little boat, i really want to still work on it, but probably next year. I'm going to find a boat that only needs a floor and transom replacement, the keel was just the last straw. Thank you all for your advice and taking time out of your days to Respond to me, i really appreciate it!

Sorry ..... I posted before I read that you were giving up on her. The Keel is not that big of a deal. It is a little more work but not that bad. I just cut the top of the keel off and dug out all of the rotted wood.

Then I replaced the wood with a strip of fir from the lumber yard ( I think it cost under 3 dollars )

And then glassed it in:

You have to replace the keel because your main stringer is bolted to the hull thru the keel. Without strong wood in there your stringer is kind of just floating.

Re: 1960's 13' MFG carefree Rebuild (complete noob, i know nothing about this!)

Did you measure them both as per this:

Which boat is 21? The MFG? @19" the 28hp should be fine. When you fire it up & run the boat on plane w/ a usual load in the boat, w/ the weight distribution of your set up (fore & aft), w/ a usual # of people, there may need to be some adjustments to the motor up or down on the transom.

The 1966 16' Starcrafts Transom depth is 21 inches, the measurment of my motor from where the bracket meets the boat to the cavitation plate is about 18 inches. Now is it possible to lower a transom? The boat i'm speaking of is the one on craigslist http://burlington.craigslist.org/boa/3118053852.html

Okay, I've deided to give this boat restoration a second try. I'm just stumped on how much csm and 1708 I need to get. How is this stuff even applied, it seems like such a mystery. Do you apply csm 1708 csm 1708 csm 1708? Or what? I'm really stumped and just want to figure this out so I can order my materials. Is the layering pettern different for the keel then it is the transom? What makes the overall thickness of the glass?

The first link in my signature has drawings and the details you need.

Re: 1960's 13' MFG carefree Rebuild (complete noob, i know nothing about this!)

Perfect, now I get it! Thank you. So what would the layering pattern for the keel be? I Imagine it would need more 1708 since its the outside of the boat?

Re: 1960's 13' MFG carefree Rebuild (complete noob, i know nothing about this!)

So far I've ordered 5 gallons of #404, 15 yards of 1 1/2oz csm and 10 yards of 1708. It might seem like alot , but I'm sure ill be able to use extra stuff for other projects.My deceased father left me behind a 19 ' Renken boat, I'll probobly use the left over materials for that. Does anyone know what the shelf life of #404 poly resin is?

I do have all 3 stringers. Its odd how short your side stringers are, its as if someone cut them down because mine are much longer. Mine are about 7 feet long

Re: 1960's 13' MFG carefree Rebuild (complete noob, i know nothing about this!)

Hey Jon Sob, I changed the order to 3 gallons resin, do you think that's enough?

Re: 1960's 13' MFG carefree Rebuild (complete noob, i know nothing about this!)

All I have is a 5x1/8 pipeline type angle grinder disk, is this ideal?

These are the type of rollers that I used but I used 6" :

Re: 1960's 13' MFG carefree Rebuild (I'm back on track and ready to go!)

So I've decided it actually is worth my time to fix this boat. I've ordered all my. Materials, they should be here on Thursday. I just got out the angle grinder and cut off the two parts of the top rail on the stearn about half a foot from the back. It looks like the transom has been redone previously, in a very poor way. The person cut out the inner skin, replaced the wood, but put it in 6" from each side. It wasn't even touching the port and starboard side...... You'll see in the pictures. The inner skin was so easy to remove that I just pulled it out with my hands. So now I have the inner skin out and I'm in the process of cleaning up the outter. What would you recommend for sanding/grinding it all smooth?

Re: 1960's 13' MFG carefree Rebuild (I'm back on track and ready to go!)

I used a coarse flap sanding disk on my 4 1/2 " angle grinder. You can also use a 60 grit disk with the back pad on your grinder .
Don't forget the ppe..

Re: 1960's 13' MFG carefree Rebuild (I'm back on track and ready to go!)

Hey Boat ..... the wood in my transom was mush but if you are able to save the wood out of yours and use it for a pattern for the new one that would be great. There is a curve at the bottom of the transom that was really tricky to do. After you take out your old transom and get the glass all cleaned out then you will be able to see the curve where the stern meets the hull. I didn't see this curve until after my new transom was all glued together flat and I tried a dry fit. I didn't want to make a new one so I sanded the heck out of it until I was able to get the right shape.

Re: 1960's 13' MFG carefree Rebuild (I'm back on track and ready to go!)

How do I go about making a exact template of my boats stearn for a transom? I Had a crazy idea of turning the stearn into a concrete mold and filling it with concrete and chickenwire. The stearn would of coourse have bracing around it to hold a consistent shape. Do you guys think this idea will work? Then I should have an exact concrete template to transfer over to plywood? Its jusrt a thought, I want this to be exact.

Re: 1960's 13' MFG carefree Rebuild (I'm back on track and ready to go!)

Also, what grade and thickness of plywood should I get? I was thinking4 pieces of 1/4 Laminated together with csm and resin between each piece?

Basically you will make Three Identical Transom pieces out of 3/8" plywood (I used exterior grade, not pressure treated, fir that I picked up from a local lumber yard ) I was told not to use pine. PB glue the first one in. Then glass in a layer of mat and PB glue in the next layer and then finally the last. That way it will conform to the outer skin of the boat. I don't know if you have already seen these clamps but you might want to make a set for your transom ...... they work great.

Re: 1960's 13' MFG carefree Rebuild (I'm back on track and ready to go!)

Concrete seems like a lot of heavy, hard & messy work for a template.

If you've got scrap 1/4" luaun, run it thru a table saw & make some 1.5" strips. You can use hot glue to assemble the pieces as you score them for length & fit them along the outside (from the boats interior) edges of the transom's shape. Have you ever seen a countertop company make a kitchen counter template this way, very similar can be done for your transom:
http://www.youtube.com/watch?v=k4sY1dEuOcs

You can make a paper template out of any substantial paper: Heavy construction paper, posterboard, red rosen (sp?) paper (comes in a big pinkish colored roll in the flooring or lumber departments) or even cardboard. You can also rough shape a piece of the blue/pink insulation from HD/Lowes. Anyway you make a template, you may want to lay it out & cut it out of that blue/pink sheets anyway as a test piece. It's much lighter & easier to fine tune into the correct shape then plywood is.

You'll want to make it @ 1/4" shorter on all sides then the existing exterior glass skin is as well. A 'tight' very close fit won't allow you to get sufficient amounts of squeeze out of the glue from behind to secure all the edges of the new work to the existing. This squeeze out is the start of your fillets and helps confirm a good bond behind & @ the wooden transom.

Jon's posted a great setup of transom clamps, and good advice about the plywood laminations. You might also use 2 pcs of 3/4" ply, if the final thickness will work it will be 1 less pc of ply to cut & 1 less joint between layers of plywood.

EDIT: The exterior of the transom has a curve to it, you can see it in the cap if you look at the pix you first posted. You'll want to maintain that curve & Jon's suggestion about using 3/8" ply & assembling it 1 pc at a time in the boat, is MUCH BETTER advise then mine @ using 3/4". 3/4" would tend to flatten the transom & that isn't good. Sorry. Many boats will take the 3/4" & I got it wrong for your boat.

Re: 1960's 13' MFG carefree Rebuild (I'm back on track and ready to go!)

I've grinded the inner skin smooth with my flap sander angle grinder disk, while doing so I accidentally made a few small holes in the floor. SThe skin seemed way too thin inn these spots. Shouldn't be too hard to repair. Now my concern with making my transom template now is the two tears in the stearn. If youlook at my first photos you will see the tears. I think the tears are making the stearn an irregular shape and they should probobly be repaired before making my transom. How should I go about doing this?
