Re: First attempt at boat repair

I got a couple sheets of ply, and next weekend I will be starting on some light sanding and cutting stringers

Re: First attempt at boat repair

Put in first order with USC, getting 2 gals resin, 5 yards of 50 inch csm, as soon as it gets here I get to start building stringers

Re: First attempt at boat repair

What plywood did you get? When you cut the stringers check for voids on the edges and if there are any fill em with some of this...

When it dries it's rock hard and 100% waterproof. TIP: A little bit of water goes a LONG way when mixing this stuff.

Make sure to precoat all the wood with resin prior to applying the CSM. Go easy on the Resin and work from the middle out to the edges. Check the first link in my signature below. Lots of good info on how to do what you're gunna be doin. If you tear the edges of the CSM and use a Chip brush to DAB the resin at the torn edges it will lay over the top edges of the stringers much easier.

That filler is water based and not waterproof, directions state it must be painted for outdoor use. I think a dab of peanut butter would be a much better choice for filling voids just before bedding in the stringers.

Sorry bout that, I stand corrected! I've always used it in a Painted environment so just made the fatal mistake of assuming. Since it will be coated in resin, still would prolly be ok but not reason to take the chance. PB would be much more reasonable. Thanks JNG!!!

Re: First attempt at boat repair

I am using some 3/4" BCX I picked up from the local Big Box for the stringers, Putting 4 layers in the rear where the engine was (priginaly 2 layers 2x12 dimensional) and putting a single 3/4" in the place of the original stringers. As for the water putty, thanks for the advice, I havent used thatt stuff since I was a kid, but I still remember mixing and sanding it, I am just going to have to make sure I get it sealed real well, since I will not be using PB on this build.

Re: First attempt at boat repair

If I may ask, why are you not using PB? What will you be using for your filleting material?

I think you suggested the water putty .. why would you use that if you already are using PB ? .. just wondering ..

YD.

He said hew was NOT using PB

Re: First attempt at boat repair

I am using PL for filleting, and glassing it all in.

On an entirely unrelated note, I wonder who is going to take care of the repairs for the boat shot to heck in Watertown? shame to thrash such a beautiful boat.

Re: First attempt at boat repair

Hi RC,
Just read you have scored some building supplies, awesome!
Now you just need the weather and the Admiral to agree!
I have been getting caught up and have read you are planning on using PL for your bedding...
Have you done any of it yet?
I ask because I care...
We have been having some discussions lately throughout the forum and it is slowly becoming the general feeling that PL may not be the best way to bed stringers and such...
Some of the concerns that have come up is the PL continuing to outgas while trying to tab and having the tabbing delaminate or the dreaded bubbling that happens to PL when it is used as a bed and Fillet...
I am pretty sure that if you just use a small thin ribbon of it to lightly bed the stringers and let it cure completely, at least 72 hours, the problems are minimized or even eliminated...then finish the fill and fillet with PB prior to tabbing...BUT that seems like a waste of energy and materials when you can just PB everything in one shot.
Just putting an observation out here for thought...

No matter, I am just glad to see you being able to get back on this resto...
Best regards,
GT1M

Re: First attempt at boat repair

This ^^^ is very true. the PL fillets will require a Loooooong time before you can glass over it and then theres no guarantee that the glass will adhere really well to it. At the very least you will need to wash thoroughly with acetone prior to laying the glass. Your PB fillets will cost approx $100 more for the resin and Cabosil. But I bet you will spend that much for the PL so I'd say it's a wash in cost's. Just my observation.

Re: First attempt at boat repair

With the filleting, I know that PL requires a long time to set up, but with my given work schedule, it really isnt going to be an issue. I am working 2 week rotations all summer, so the PL will have between 2 and 6 weeks to cure fully before any glass goes over it, and I will be doing an acetone wash.

As far as work on the boat is concerned, I just need nature to make up its mind. it has snowed the 9-12, the 18th, the 20th, and again on the 22nd and 23rd. 8 days of snow this month, and it is April. weather forcast this trip home looks good, low of 43 high of 78. I really hope May agrees to cooperate.

Re: First attempt at boat repair

The real reasoning is money, the more resin I use the costs go up a ton for me. I would love to buy bulk, but MEKP has such a short shelf life. If I order resin, I will have to order MEKP every 2 months to keep going. 2-4 days a month work time means a lot of wasted materal, and shipping charges add up real quick

 

[Woodonglass]

Re: First attempt at boat repair

Not sure what you mean? The shelf life of MEKP is not that bad. As long as you keep the mekp in a kool dry place (70? or less and No Direct Sunlight) it will stay good for at least 6 months or more. I've had some last longer than a year. In your South Dakota climate, storing your MEKP in an interior closet should not be an issue. If you bought 5 Gallons of Resin with the appropriate amount of MEKP today, I'm positive it would be as good as new in October. What you spend on the PL will offset the Price of the Resin by more than 1/2 I'm thinkin.

Re: First attempt at boat repair

I had read the MEKP is only good for 2 months, USC even has it up to only order what can be used in 2 months time. I may be wrong on that, but I built the budget for the boat around PL filleting, I already bought an entire case of 12 28 oz tubes only ran me $70 through a friends construction company.

Re: First attempt at boat repair

True, for them to stand behind their guarantee they will say that, however from a practical experienced Factual point of view, it's more than double that. I'm not telling you that what you are going to do will not work, It's just that glassing over PL is not Optimum. If you make your fillets small and keep them neat and not smeared all over the wood then you'll be fine. And like you say, you're not in a hurry and will have plenty of cure time so you are the exception to the rule. Just want to make sure you are aware of the issues with PL and Polyester resin. By the way that's a GREAT price on the PL.

Re: First attempt at boat repair

That's a great deal on the PL...
Woody's correct about the resin and MEK-P...
On the MEK-P...if you keep it in the fridge, in a ziplock bag, so your better half doesn't smell it...it will last a very long time...many months...
Resin, if kept cool and dry and dark, also many, many months...

Re: First attempt at boat repair

I kinda started a salt water aquarium over the winter months, and needless to say the dear wife wasnt too happy when she got my USC order to place. Since I am gone so much, I have my wife place my orders, she knows what the budget looks like, personally I got no clue. If i am to keep my salt tank, she said I have to pare back a bit, so I committed to the PL so I wouldnt have to get rid of the tank. I spent 2 weeks reading up on the particulars of PL, and even called a boat yard in southern georgia that repared my friends charter boats, and he got me tons of info on PL straight from Loctite, and even filleted some scrap, gave it a quick glassing (1 coat CSM, and 1 coat biax) put it on a chain and tossed it in lazaretto creek for a couple weeks. no delam at the fillet, but there was some pretty bad damage where the anchor chain was attached. Lazaretto is known for some real ripping currents, oyster bed, and some drastic tidal shifts.
