Re: Man vs. Boat (season 1).

I am officially an iboats junkie. The first step is admitting you have a problem... As I type this, I am sitting in a tent freezing my butt off on a cub scout camp out with little buddy. I am in the middle of nowhere but miraculously have a 3G connection on the iPad. Nice to be able to thumb through some threads before I (trying to) doze off. Got a big day planned for tomorrow on the boat...the boat has been moved inside...it was quite the adventure... Will update with some footage soon... Hope everyone is well.

You are in good company buddy

Far worse things you could be in to!

Enjoy your Saturday glass work

Re: Man vs. Boat (season 1).

looks like you are about to reach a turning point. keep it up you are about to hit the true fun part of the resto. Looks good.

Re: Man vs. Boat (season 1).

Hey guys:
Still plodding along. Below is the video from the last couple of work sessions. No special production features.... Didn't really have time to spice this one up. You will get a kick out of what happens at about 3:01. Small miracle that no cuss words were involved.

The basic summary of where we are:

1. I have got the transom template cut. Still thinking about the best way to tackle that. The video overview will give you guys a better idea of the shape of my transom, etc...
2. The boat has been moved inside. I didn't just want to slide it off the trailer onto the bunks. I might have ended up like Jasoutside with my boat lying on the ground. So, we hoisted it with 2 tractors - pushed the trailer out from under it, then put the bunks in place, lowered her down and rolled her right into the bay in the shop.
3. I got the boat cradle built. While the little dollies were good, the boat was certainly a bit tippy and it was too wobbly to start digging into my structural work. Pretty took much entire Saturday work session, but had to be done.

I think I am finally getting ready to start some glassing. I am also going to be pulling the engine out of the donor boat so we can do some winter maintenance on it and so I can get a better look at the engine mounts/stringers for purposes of rebuilding my engine bay/mounts.

Hope all is well.

Re: Man vs. Boat (season 1).

It would likely delaminate if you just forced the hull to conform to a flat piece. The template looks good though.
I wouldn't cut those things... I would pull the cap before I did that... unless they will be covered by the doghouse?
Tractors are cool! I want one!
Is your shop heated?? You can "fool" the fiberglass with heat lamps or a good heater if it isn't..
I think my entire boat project was a "wag"...
Cool way to keep the wood flat with the stickers and what a great weight

Re: Man vs. Boat (season 1).

Ok, being in the bulding industry for years, I have had to bend a few pieces of plywood in my lifetime for curved stairs ect. You are trying to keep your plywood straight, when you should be stacking them, wetting them down and weighing them down to curve them to the curviture of your transom. I have to run out the door, but if you want more info on how, let me know.

Hmmm, let me just play that 3 minute mark one more time.

Aaaaaaaaannnnnd bam! Yup, there we go

Re: Man vs. Boat (season 1).

Hey PM,

Looking at your vid I came up with another possible way to curve your plywood. Make some Kerf cuts vertically, start with 4- 6, 1/8-1/4" deep, and test to see if that gives you enough of a bend...add more or deeper ones as needed. I believe that with a good resin wet out, some PB in the kerfs, maybe a layer of CSM, and a good layer of PB before you attach it to the hull, you should be OK...The biggest difference is you would probably have to lay in the transom as two separate layers, instead of just one...Or Pre-curve both pieces of plywood, adhere them together, and then do it as one piece...

Plus, cutting away the sections you mentioned should definitely give you the clearance for the installation.

And you don't have to basket weave it...LOL

GT1M

IF you want to curve the transom, I would do this. IDK about kerf cuts, it might weaken it, but I'd imagine with all the glass it would be fine

Re: Man vs. Boat (season 1).

OOOps!!,

The puter froze up on me as I was watching the vid and started my answer before I got to the part where you were trying to straighten out the plywood...WAIT A MiNuTe!!!

Isn't that what you need for the Curved??? Transom??? Curved Plywood??? Just Sayin...

 

[Mike Lammert]

Re: Man vs. Boat (season 1).

PMC, I have to second the other guys here, you are trying to straighten out plywood that probably already has the perfect curve that you are looking for....I don't see any way it would weaken your laminate if both pieces are pre curved before glassing.....Just my $.02

Thanks. I agree.. Tractors are fun. I am jealous of jason's with the lift hitch.
The shop has central heat, so that's why I wanted to get the boat in there for glassin. I am not going to cut the glass overhangs if I can help it, although they are covered up completely by doghouse and rear jump seats.

Understood. That wood stacked is primarily for my stringers, which I do want straight as possible. I have some thinner 1/2 arauco (sp?) that will bend easier to shape if I decide to curve the transom. It has to be dead-level flat around the keyhole, though, for the merc outdrive. I may do a multi-piece transom with flat pieces and
Csm/pb build-ups, because curving the ply involves water (which means problems or extended dry time)....

Ummm..GT, Sounds awesome, if I only knew what a kerf is...sounds like a muppet or a fraggle to me.....

Jas, I edited out all of that section, but kept the head knock especially for you, because I knew you would be the guy to put that on loop repeat and laugh...score, I'm glad you liked it.
If you can't laugh at yourself, then life's no fun.

Sorry PM, a kerf refers to the thickness of a saw blade. A kerf as it applies to wood is a shallow cut in a piece of wood that it usually used to help the wood curve to a desired shape...following is a kindergarten type drawing to try and help 'Splain...

Try it with a scrap piece of lumber, then some scrap plywood to get the idea...hope this helps.

Now you are on my level! :facepalm:

Thanks...we'll figure this thing out together...iboats style.

Couldnt do this without you guys.. Thanks to all for the help and input.

Re: Man vs. Boat (season 1).

Nice looking progress, glad to see you are inside for the winter.....it showed up here today....I HATE WINTER...except it is a good reason to work on boats

On the stickers, I see a weight distribution issue....it takes a lot more beer to weigh the ply down....maybe I should zip out there and give you a hand? And a disclaimer (I have my attorney writing the formal document), I can't promise the ply will flatten out......wood has a tendency to have a mind of its own (I can hear the tinny's saying "see I told you so".....but I haven't seen any headlines about a "super model shredded by ginsu knife like plywood" lately.....but then again they all hang out on glassers with nice smooth corners...... ) Depending on the lamination it may want to curl some....but having a even moisture content is a big plus.

On the transom, I don't think you are going to force the glass to do what you want it to....or not in a big area. I like the 3 piece transom idea. Or just build up your transom out of 1/4" plywood? That way you don't have to deal with kerfs (good idea by the way) or bending the plywood etc (hopefully). By the way is it a compound curve or a simple curve (compound curves in two directions at once....much harder to deal with) What would be helpful is to take a Merc out-drive and put it up against the transom (or a template of one). If you could do that we could see what you really need to deal with in regards to the mounting issue. I think you need to address the curve around the mounting area, and the rest of the transom independently. That is my two cents for what it's worth!

 

[zopperman]

Re: Man vs. Boat (season 1).

I have an idea. 3 piece transom, I would tab the stingers into the transom and make knee braces... That way it will be flat and definitely strong enough

 

[BobsGlasstream]

Re: Man vs. Boat (season 1).

My personnel opinion.
I would use thinner ply, like 1/2 ", I would precut all the ply and put them in one sheet at a time. I would use clamps that match the curve of the transom as long as the curve is the original design. I think andgott had a curved transom on one of his boats. Not sure. The end result would be stronger then the normal transom just because of the curve and the additional glass. My only concern would be the flatness spec. for Mercruser system.
Good luck
Bob

Re: Man vs. Boat (season 1).

If you try and bend the plywood it is actually pretty easy and can be reasonabley fast to do. Yes, it will involve water, but after shaping/bending the peices while wet, you will then run a fan and heater if you have one available to quiken the dry time. Almost all Chris Crafts that I have seen have a curved transom. Its part of what makes them elegant looking and beautiful.

The kerfs that were mentioned can also be done, but I would try and bend first using moisture and clamping them to the transom. You don't have to get them perfectly curved in the first try. You work them until they are curved properly.

3/4 or 5/8' ply will sometimes be a better choice to bend because half inch can sometimes break easily when trying to bend it permanantly. The marine ply will be stronger just because it has more layers.

Anything worthwhile takes time. Don't get in a rush and do things right the first time. Better to think twice, measure 3 times and cut once! I would think about removing the rear cap, cut it a few feet forward of the stern on both sides and lift it all off. Assuming it was built with a cap!
