Re: 1st restore on a 14ft ski boat

Hull seems ok i think the water came in where the top cap meets the bottom under the rub rail and definetely the transom was letting it in trough one of it numerous drill holes.

Re: 1st restore on a 14ft ski boat

damomul, I'm looking at the kingspan route I'm just trying to make sure i have hte right foam as I don't want to put in the wrongon e and find that if I do take on water that it'll retain it.
MBFG have used them thanks.
I used the flap discs when grinding and you would have to agree nothing seems as good as the first 5 seconds when you change discs , it justs eats fibreglass up!! then not so much Man i hated that bit of it and I didn't even do a good job on it.. hope when I flip it over it's not as bad..

What did you use onthe deck paintwise?

Hi,

Due to a rush of blood to the head ( and a broken piston ring :facepalm View attachment 105492

Thant is a cool looking boat.

Great little project to get your feet wet. No too expensive either.

Re: 1st restore on a 14ft ski boat

Here are the pics of the top side stripped down. I would like to fill in the holes where the splashwell grommets are and redrill them. Reason being is that 1. i have 3 and only need two. 2. The grommets I'm going to replace them with are actually a slightly smaller diameter so i want smaller holes.
I guess it's just a thing of grnding down the edges on both sides and them covering with csm, woven and csm ?? or is this overkill?










The dash is 1/2 inch ply the fibreglassed over, and becuase it's like this it's a bit tricky trying to get switches and wiring done as the thickness is a problem.
Can i cut this out and change to 1/4 " ply or how would I go about making the same shape out of glass? I am a bit of a novice at glassing and don't have an idea on how to make a template.

If I have to leave the dash there what is the best way to cover over the hole the steering left and all along the the side of the cap there are numerous holes from upholstery being attached and god knows what , so these will all get filled in. The upholstery that is going to be replaced I'm thinking of attaching it back on with a strong builders adhesive that way I won't have to redrill the cap and the result should be the same.

one more thing , when measuring out the resin does anyone have any little tips or tricks on how to measure the MEKP ???

Re: 1st restore on a 14ft ski boat

I'm a rookie glasser too. Have faith! It's much easier than you think. Use a little more hardener than they recommend. See my thread again... It should have a lot of useful tips for a novice. Also, produce guy made an awesome dash from cardboard and glass mat. See his thread too! Good luck, post pics!!!

Re: 1st restore on a 14ft ski boat

2% by weight mate. but i go by volume as its easier and much the same. so if you mix 100mls of resin use 2 mls of MEKP. the more MEkP you use the quicker it will set. it wont make it any harder.
good luck you will pick it up as you go.
if you are going to do two layers of glass do them one after the other. dont wait for the first to dey, sand down and then do another layer . just a wee tip.

Re: 1st restore on a 14ft ski boat

Hey, yea the first few seconds are great. just enough to get you going, hey this should not be too bad...

i spent a solid 8hrs one day and knocked through the most of it. Thankfully only managed to total one grinder. now the grinder i used was quite a beefy one. Parkside from Lidl. whats even better is that it was my old man's so didnt have to pay for it!!! is still works but the bearing is very noisy!!!

The Deck is not done yet. I am aiming to put my engine mounts back in this weekend. Then hopefully get the deck cut and fitted before next weekend. I am going to seal the underside with resin and CSM then a coat of CSM Roving then CSM again on the topside for strength. i will then coat it all in Topcoat. Which is really waxed Gel. I am intending on putting on two coats, so i may get some gel to save having to sand off all the wax of the topcoat. I plan to put on snapin carpet at some stage. but not this year. I choose the topcoat for its durability. My boat is almost 20yrs old and i doubt that any paint will have stood the test of time like the original gel on the hull.

i have been measuring using a general plastic measuring jug, and the hardener with a medical syringe. It does recommend doing it by weight, tho it wont be that far out. if you mix it at about 1-2% has worked out fine for me.

Remember to wipe the area down with acetone first. really helps to clear all the contamination and help the bond. It is daunting at first but after a few mixes you soon get the hang of it. Finally a good Respirator is Key. Them fumes are nasty particularly the acetone. Oh and your clothes will STINK!!!! That said you cant beat the feeling when you stand back and see the reconstruction process begin!!!

Sorry for the essay but i tend to get carried away...

Re: 1st restore on a 14ft ski boat

I hate to disagree, but the sheet I got from USC says use 1% with a POLY RESIN and 2% with a gelcoat. I've been using 1 % in 85 degree weather.. I'm guessing it's a bit cooler in Ireland (at least it was when I was there!) so you might want to do 1.5 %. For instance, they recommend, 1/4 oz MEKP per 32 Oz of resin.

X2 on the RESPIRATOR RESPIRATOR RESPIRATOR!! and a tyvek suit, resin burns like hell on your skin. The MEKP should also come witha measuring cup.. it looks like a shot glass.

Take a look at Produce Guy's dash, It's AWESOME. I'm doing a 1/2" ply dash coated with 2 layers of bondo cloth (like a roving) + gelcoat. I routed out spaces for the switches and recessed the back of the wood where the witches go. I'll posta pic on my thread this week when I finish it. PS -- ALWAYS precoat your wood in resin so you don't get air pockets. Teh wood soaks up aenough resin that it will be detriment to your glass coat not to pre soak it!

I'm a HUGE novice to glassing. There's a lot of good info in my resto thread for rookie glassing.

Be safe and good luck. Keep the pics coming and keep your head up.. i found it very daunting at first.

Re: 1st restore on a 14ft ski boat

good info there guys , thanks for your help.
I'll start at 2% and see how it goes and mess arounf if i have to.

A good respirator was one of the first things on my list a few weeks ago, everyone states to gets one , and only after grinding on the hull I can def see why.

 

[damomul]

Re: 1st restore on a 14ft ski boat

Yea 2% isn't too bad to start with especially if you intend to mix in the evening. The ambient temp makes a big difference and it is quite cool here. If you mix it a bit stronger the worst that is going to happen is that it will knock off a bit quicker.

The main thing to remember is that the longer the resin is in a pot the quicker it will set. Heat accelerates the reaction and as the reaction occurs it in turn generates more heat. That said i was glassing last weekend and at about 1.5% i was getting about 15-20mins working time. Was approx 20degrees up here in the Antrim Glenns. Mix small batches at first. I think mine was about 250ml resin, i measured the MEKP with a 5ml syringe. This helped keep the measurements easy.

One thing i have noticed is that the MEKP stripped off the markings on my syringe. Tho as previously mentioned the measurements are not mission critical.

Re: 1st restore on a 14ft ski boat

20 degrees!?! (IS that by Giant's causeway?) I would be using AT LEAST 2 % in temps that cold..

Nice shakespeare it will look fab with that engine, the guys in the engine forums are a nice bunch , they've always been great help to me when I needed info..

Re: 1st restore on a 14ft ski boat

cold!! Man that's summer weather over here
we all get our shorts on at 17 +

2% it is so for my mix by the sound of it

 

[zopperman]

Re: 1st restore on a 14ft ski boat

:facepalm:

I was talking Fahrenheit. I'd start with 2 % anyway if it's not really hot. It won't have any negative side effects, assuming you can work with it relatively quickly.

Re: 1st restore on a 14ft ski boat

Ok today I started cutting my timber up, 2 x 3/4 for the transom, 1/2 for the deck , 3/4 for the stringers and 1/4 for the bow and stern parts removed ( i figure when I glass these that the strenght will be there so hence the 1/4" just for the shape of the pieces).

This is the transom cut up and put in place, I copied it from what I removed but my coping was a slight bit off and when cut there were slight differences between the 2 peices but the fillets will make it up



I also copied the deck from what i pulled out.

I will fix the transom in a while I plans on using CSM on the back and in between the 2 pieces then clamp in place. I have holes at the back from where the motor is attached so I'll drill using these holes to bolt the new transom tight in place and also clamp it on top.


Once set in place I plan on then filleting around it and tab it , and the stringers set in place too.

Should I glass the stringers before setting them in place or just coat them with the resin only??

So far I'm enjoying doing this as the end product will put my mind at ease when I ploughing through a bit of a chop, my jigsaw and skill saw work may need a slight bit more of concentration but overall not doing too bad.

I am aiming to get all the glasswork done this week so I can flip it and start working on sorting out the scrapes and gouges underneath her.
What is the best method to re attach the cap ? it was stapled on by a million staples but would screwing, bolting or riveting be a better job??

Re: 1st restore on a 14ft ski boat

Here's some drawings of how I recommend doing things... Unless you are using Epoxy you must use CSM with your resin or it will dry brittle and crack and allow water to penetrate.

Decks




Transoms

Re: 1st restore on a 14ft ski boat

WOW ! Wood you really make sure it'll last a lifetime, I'll follow this but I'll have to sub the 1708 for woven roving.....

I'll cover all Parts with CSM before setting them in place...

thanks.

oh,

what's PL adhesive is it like a silicone adhesive????

 

[zopperman]

Re: 1st restore on a 14ft ski boat

Sort of.. but I believe it's polyuethane based, not silicone. I Just used PL to lay the first part of my new deck to my stringers last night..
