Chris, your work continues to be outstanding.

and your comments continue to inspire me Thanks for checking in on me! Any thoughts about the drain holes or the poly for the deck? Oh what would you know tin man

Actually, it wasn't terrible but I didn't like working with it. Epoxy is easy to measure, gives you plenty of time to work and you don't have to sit there counting little drops of MEPK.

If you really want to do poly for the deck, encapsulate the deck prior to with it then then use epoxy to tab in and for final glassing. But that's just me.

THat was my exact thoughts. Glass the ply on sawhorses with poly then PL the deck in and use the rest of my epoxy for the joints and to tab it in using remnants of the 1708. I am using 9.5oz twill for the deck.

Is the poly really THAT bad? How much resin do you guess I will need for the top and bottom of my deck? It is roughly 14' long by about 50ish" wide obviously narrowing to the bow point.

I am not only asking you, but you would have knowledge of how much epoxy the type of glass you are using on your transom is taking up. I know my 8.5oz tape doesnt use hardly any...now 1708, that crap seems to need an electric pump and pressure washer to apply enough

I haven't had the pleasure of working with 1708 yet. My time is coming REAL soon!

how much does the stuff you are using on your transom tabbing soak up? I mean, do you really even have to brush any on after you have wet the surface? THats how my 8.5 is, just brush on some resin and press the glass in. 1708, putting resin on the surface doesnt even put a dent in the wet out process

When I tabbed tonight, I pretty sure I used a total of 9oz's - 6 to wet surface and 3 to touch up.

Re: 1973 wellcraft 165 sport airslot project w/ pics

cool, so that isnt that much. What weight is the glass you used? You are going to LOVE 1708. Get ready to watch your resin go bye bye!

Re: 1973 wellcraft 165 sport airslot project w/ pics

9 oz of resin was probably a little heavy. I've got a couple of spots that are smooth where you can't feel the cloth. I even used the brush to remove it with no success.

10 oz. cloth and tape is what I've been using.

Hey Chris,

Your work is incredible dude... Super pro man...

It's been awhile since I checked out progress, wow....

Peace,

Re: 1973 wellcraft 165 sport airslot project w/ pics

Hi Chris,

I was wondering if you sanded in between layers of glass when using epoxy?
If so, what did you use and what grit?

Right now, I'm using a finishing sander with 60 grit then hand scuffing with 36 grit. Not sure if I'm overdoing it and wasting time?

Thanks,
Mike

Sanding of any type is never wasted time in boat building, so ive learned The answer is sometimes. If the glass that you just laid down is 30 hours( pulled that out of my anus) or newer, keep on keepin on! Usually, if I have time to glass the whole thing at once I just do all the layers that I am doing at one time. BIG time saver there! I have done as much as 2 layers of 8.5oz tabbing and 2 layers of 1708 at the same time! That is to say, wet out surface, layup the first layer, finish as those this is the only layer, then repeat for as many layers as you need or can get through in time. That I think is the one thing that I really got right on my project. I used 3 to 1 epoxy. It gives a LONG window of work time as long as you get the stuff out of the pot quickly. Mine takes just about 3 hours to where it is gelled. Not dry mind you but end of its working life.

So, if you laid up a layer last Friday, yes, sand before moving on to the next layer. I am using two methods. For most of my work I have used a random orbit sander with 100 grit just because it has a dust bag and it has been hot so I am usually doing this in shorts(yeah, sticky epoxy knees) and a t shirt and of course a respirator and goggles just in case. Also If it is cool out and I have a lot of work to do and know I am going to make a hell of a mess with what it is I am doing I will use the grinder with a 60grit flapper. Just lightly. It goesWAY faster than the hand sander and also does a better job. You can pick out the difference in my pictures. When I dont care if I have a few air pockets I just use the sander but if I want complete perfection I use the grinder.

THe biggest thing you will learn is that 1708 after wet out has stiching that sticks up every quarter inch and this almost makes it impossible to get a layer to lay perfect with no bubbles over top of it So if you want it to lay perfect, plan on grinding those stitches away. I would have done that had I not been laying it up in multiple layers at once. It would have produced a much nicer product...

And yes, I do hand sand as well. In the corners and places that the grinder or sander wont go. I just use the same 100grit paper.

Re: 1973 wellcraft 165 sport airslot project w/ pics

Thanks for the info. Luckily I only have to do two layers of 1708 on the transom. Everything else is only getting one. I know all to well about the sticky knees and forearms. I glued the transom in wearing shorts and a tee. BIG MISTAKE! I'm still pulling resin off my arms.

What have you decided regarding the poly for your deck? Keep me posted with what you are thinking.

need to calculate how much resin is going to be needed. THat will make up my mind for me. I will likely go with epoxy again though as I started with it, so I may as well finish with it. If the understructure is going to last for 6000 years the deck probably should too I guess...

What I am really needing to know is if I should epoxy PB coat the drainholes only or if I should use the pvc that I bought to fit in the hole. The pvc when installed sits about 1/4" from the flat of the hull therefore these would not drain ALL of the water. Or so I assume. But if I dont use it then will the wood be more likely to rot faster without the plastic protection. I would think it would.

Looking awesome, Chris! The new tank looks quite at home in there.

For the deck, I think I used 5 gallons (if I recall..) for the CSM top and bottom of my deck, including tabbing in. It was a load of poly, but that was a load of CSM, too. My scrap glass bin filled up fast cutting those pieces. That used by far the most in-one-shot resin so far. I estimate the entire above-deck glassing will be 5 gallons total. Redoing something above deck years later, no biggie. Redoing a deck ever again, no f'ing way!

Thanks Lowkee, that was what I estimated as well. 5gals ought to do it. But I think I will use way less. For some reason I have only used about 6 gals total for my rebuild so far and remember I also did a full layup of 1708 on the hull bottom. SO I am using far less resin than most on here for some reason I just think it is because I have not wasted any at all and that I work with such small quantities and with a brush instead of a roller.

I was amazed the first time I used the glass rollers that I bought on just coating the transom wood, it took like half a quart and after I used a brush doing the same thing on the other side it only uesd 3 squirts of epoxy and 1 squirt of hardener. Thats like 1/8 of a quart Big difference.

So I think I will go ahead and order 3 more gallons of epoxy and see where that gets me.

DO YOU KNOW HOW HARD IT IS TO DRILL INTO A TRANSOM AND STRINGERS THAT YOU HAVE SLAVED OVER FOR MONTHS TRYING TO WATERPROOF?????????? My god is it a terrible feeling The only nice thing about it is getting to see how thick and bonded your work is

So since no one has chimed in on whether to add PVC to the drain holes I have decided to install them and be on the safe side. I figure the rest of the stringer has no exposed wood, and by exposed I mean raw or thickened epoxy coated, so why drill 1 1/4" holes in them and not fill them with something I hate that water will have to stand a bit before draining but I guess that is the way most boats are made. Not to mention my transom drain originally sat about a full inch of the bottom of the hull

When I just drilled all the through hull holes I over drilled them 1/4" and intend to refill them with PB, let that cure, then redrill to the correct size. I also drilled the transom drain down to about 1/4" above the hull bottom and am thinking of building up the bottom of the bilge so that it is flat and flush. Maybe...if I do, I am going to go and buy some CSM for that as it would take 5 or more layers of 1708 to get that thickness. I have lots of extra but I dont feel like putting in the effort that 1708 requires to layup. However the good news is that I could do it standing behind the transom at semi table height

Well, everyone that has an opperational boat, have a great, safe labor day on the water and to the rest of us sad souls, get lots of work done and enjoy the start of the college football season! GO BUCKS!!!!

I know the feeling. When I installed my CMC power trim unit, I had to drive 4 holes to bolt the unit on the transom. I just about cried, but I got over it, somewhat.
