new here have question

[lazyfish]

I have been reading some of the threade and I wonder what pl and fillet means when repairing rotted wood or stringers.Thanks very much.If this is not in the right place let me know,I did not see a question and answer or a faq for hull repairs.Thanks

Re: new here have question

This Pic should tell the story...

Filleting material can be PL (Construction Adhesive sold at LOWES or Home Depot) or Peanut Butter (Resin either Poly or Epoxy mixed with cabosil and chopped fiberglass fibers) This filleting helps when it comes time to tab(lay the glass) on the stringer and the hull. Glass does NOT like Square Corners.

Re: new here have question

Well here I go as well,I have a 71 kingfisher that I need to redo the floor and transom.I have read enough on here that I want to attempt the project.This is the first time I ever attempted something like this,but besides the work involved I am exited about the project.

It is a small humpble fishing boat,but I like it very much for some reason.I have alot of questions for the people that have done this before.

If ya`ll don`t mind I think my first question is,is the pl construction adhesive the same thing that I will glue my stringers to the hull as well as fillet material,or is it just fillet material.Forgive me if I donot have all the correct names down,stinger being the wood support that is longways with the boat.

Here are some pics of what I got started.

Re: new here have question

Yes, you can bed your stringers in PL as well.

That looks like a nice, fairly wide, stable fishing platform. I'd say it's worth fixing up. Good luck with your project.

Re: new here have question

Ditto. Cool/funky looking boat. Are those hundreds of little foam squares on the floor, or did you cut a grid into a solid sheet of foam?

 

[lazyfish]

Re: new here have question

No,they are not foam.The boat did not have stringers,they look like ends of 2x4`s cut 3/4 of an inch.there was hundreds of them.I plan on installing stringers back instead.

I guess the worth in doing the rebuild is for me,I imagine I could buy another hull for a fairly affodable price,but I would like to do this for fun as well as a great fishing boat.When I read and see some of the rebuilds here it energizes me and keeps me interested.

I have done a little more to it,I will post the pics tonight.

Re: new here have question

weird how they used all those block of wood? It'll be a fun project and you'll learn tons! Plus, when it's all said and done you'll know exactly how she's put together and what she's made of. Good luck! Keep us posted.

Re: new here have question

Well I finally got it all tore down.I think the next task is to sand the whole inside of the hull.I am going to fill the places in the bottom where some of the fiberglass pulled out with the little square wood pieces that was there instead of stringers.

There is a layer of fiberglass that was used to adhere the wood pieces to the hull and is not the actual bottom of the boat.My idea is to sand or grind the thins spots square so I can glass them back flush with the layer that held the small wood pieces in place.And then install another layer of fiberglass over the whole bottom of the hull.And then I will have a nice clean new layer of fiberglass to bed my stingers to.

What do yall think?

Re: new here have question

Well I'm NOT a PRO but I believe what you have there is a Balsa Core Hull. Kinda like this one...

If so, You have to go about fixing it, a little differently than the normal stringer and Glass approach.
You really need to seek further advice abou this, In my opinion. I could be wrong but I don't think so.

Re: new here have question

Well I am absolutly not a pro,what kinda repair differently are you talking about.I can replace everything back the way it was,I just thought adding the stringers would increase the strength of the boat.It seems to me there was no structural support with the little wood pieces.

Re: new here have question

I have asked one of our resident PRO's to stop by and take a look. Let's wait and see if he does and what he has to say.

 

[lazyfish]

Re: new here have question

Thank you looking foward to what he has to say.

Re: new here have question

Well not a pro, but done plenty of bass boat restores and ain't never seen anything like that. Are the blocks attached? Was the deck just laying in? I'm going to do some investigating on this one and will get back with you..

This is just really really odd....thanks for posting it.

Don't worry thought it's still a boat and we'll get through it

Yes the blocks were attached with what looks like to me to be either some sort of epoxy or it was the fiberglass resin,then the resin was poured or spread over the top of the blocks and fiberglassed and that layer of fiberglass is the finished floor.

I have read further on the wood pieces on this site and there are the people with more experince than I have,that say the balsa wood pieces are excellent choice and is incrediibly strong.

Right now i have alot of sanding to do on the inside and will read up on the balsa wood core.

Replacing the core with stringers raises the floor a little and I thought I might,with the exception of the transom,might raise the cap the same amount.I am more worried about the weight of the wood stringer core and plywood floor, as compared to the weight of the balsa core and fiberglass floor.

Any pros and cons to raising the cap the same amount as the floor if I was to put stringers instead of balsa wood.

Re: new here have question

Yes balsa wood core is a good method, but you can do stringers back if you want. My question on the cap is: does the cap go all the way down and contact the deck (floor). I can't tell from the pictures.

If the cap doesn't come all the way down then raising the deck an inch or so won't hurt anything. Most stringers are 3 to as much as 12" tall, but there is nothing that says they can't be an 1" tall.

Or you could also go back with the current system. I personally haven't done one of these but can't see where it would be a biggy. You could use that system and then cover it with 1/4 marine grade plywood to give a better flatter surface for the deck (floor)

Now on the balsa core...I have seen several balsa core stringer systems and even transoms, just haven't seen the entire hull that way....And YES it is a very strong system. The balsa core is a very lightweight materail and used mostly as a filler....the fiberglass resin and cloth is what acutally adds the strength. Once the fiberglass has cured (if you could get to it) you could remove the balsa core and still have and strong laminate.

Lets us know where else we can help....

Re: new here have question

No the cap does not go all the way down,It was not a shoebox joint.The cap was actually set on top, then fiberglassed from the inside of the craft.Aroung the edges of the inside of boat will be raised about 1 inch and the 2 stringers in the middle are as tall as 2x4s in the back at transom and a little taller in the front towards the bow of boat.The floor did pitch to the center of boat and that is why the stringers are taller in the center of boat and 1 inch at the sides.

I guess I do not need the 1 inch stringers at the side of boat just cut the deck to lay on the old floor at the edges where it is all fiberglass structure and no balsa core,but i was going to add about 3 lightwieght ribs(for lack of better termonology)to support the cap as I was going to raisse the cap the same height as floor.then fiberglass the cap to the hull all the way around the boat.

I was going to cut u shapes in the ribs and the stringers were they fit together so that the were all flat and structuraly tied together.The ribs will go all the way from on side to the other.The stringers will go from one end to the other(transom to bow)

this may not be clear I willl think of another way to put it if need be.

Re: new here have question

As has already been stated that is a balsa wood core. That is some high dollar stuff if you have to replace it. I'd try to salvage all you can. People with performance boats pay good money to have balsa installed in their light weight hulls. One of my lake buddies recently paid 2 grand to have his balsa installed.

Perfectly clear, you're plan is fine...use the two part foam to fill the voids where the balsa used to be....

Re: new here have question

Sorry I missed this one..

Yes your boat has EG BASLA Core .. for some reason I don't know why.

Your pics kinda show a 5/8 - 3/4" balsa core. ON the keel/hull side. NOT good.

Make your marks and stringers to support the "deck " and possible 2 part foam your keel. ( depending on how your Draft is ).

If you do not need foam or more glass then do not replace with eg balsa core. .. just glass it ( mat and 1708 ).

YD.
