1969 Larson - Big Project

Re: 1969 Larson - Big Project

Already did that. Pictures to follow.

I have a new NOSY neighbor (who likes to bring over crappy beer) who is really interfering with my project!

"Hmm... avpaulb is working on his boat. I should go mess him up for two hours."

At any rate, I have managed to level out in preparation for stringers and deck, as well as tubing my glass.

For small boats, I have a nice and easy method for leveling. Pictures in a few. Dinner first.

Get a length of pipe that will go thru the center of the glass roll & is long enough to be supported on either end by jack stand. Treat the roll of glass like a GIANT roll of toilet paper, the pole/pipe is the roller.

Re: 1969 Larson - Big Project

Yes... the tubing idea:



I figured a great way to level out the boat in preparation for stringers/deck/transom was to attach some appropriately sized 2x4's attached from my stand to the chines at regular intervals. A bit of playing around, a few adjustments...





Haven't sanded/fared my hole filling yet, in case you didn't notice.



Boom, level to all sides and bow to stern. AND... she's rock solid. Doesn't move a bit if I walk in it and the floor is solid! Now I'm dreaming of stringers...

Undoubtedly I'll be bumping this in the morning because nobody is awake to care anyway.

You need to choose your neighbors more carefully. I had a neighbor who did all my fiberglass repairs for me as long as I supplied the beer. CAUTION: Limit the beer consumption during the repair process!

Looking Good!

Sometimes I wish I could chose my neighbors... I open the garage, boom there they are. But nobody but me is touching one inch of this project!

Beer makes everything better. But I've decided the "Wall of Shame" is going to have to go. It takes up too much space!

NEW ADVICE I'VE LEARNED (actually I was rudely reminded of it this morning): Do not wash your normal clothes with the clothes you use for your project! Fiberglass does not go away! Now I get to itch all day at work!

Well, plan for the weekend: I'm going to move forth with getting the transom glassed in, and with some luck, start laying the stringers. We'll see how it goes. I still have the transom modified to accommodate my abnormally long shafted motor, so I'm not sure what to do there.

I suppose I could just slap a ridiculous price on the thing to get rid of it, but them I'm screwed. But, lots of cleaning to do first! And I need to come up with a plan for the deck. Time to break out the line level, chalk, and sharpies!

Re: 1969 Larson - Big Project

I would think long and hard before I put the LONG SHAFT transom in. Once it's in your stuck with that configuration, OR another modification to accomodate another motor.

Yeah I know. I've found a couple other motors locally that need some work. There is a 1981 50HP Merc at our local boat repair shop. They are telling me that there is a rod knocking, but it still runs. Not sure what kind of repair that would take.

The expensive kind.

Re: 1969 Larson - Big Project

Yup, just figured that out too.

Re: 1969 Larson - Big Project

As usual, I always seem to find some other project to do other than the boat! I decided doing the majority of the fiberglass work outside was going to work out better. So,





It's starting to get hot out, so as long as I can keep any rain off of things... should work great! Only cost about $75 to build too!

I did manage to mess up one of my transom pieces, so I had to re-cut it. But in the end I managed to get some actual work done!





I should be able to get the transom glued and tabbed in tomorrow with a bit of luck and relatively warm weather!

How hot do you guys like to mix your resin to do your glue in and tabbing?

Not hot at all .. just normal working time ratio. Its not so much as how hot .. its how fast you can work and how well you planned all your glass cuts to do step A and B, and C and soforth. If you have everything planned out then you can rock and roll without stopping too much ..

YD.

Re: 1969 Larson - Big Project

Quick question... hopefully the regulars are chiming in!

Getting prepped to glue the new transom in using PB. Should I wax it or no?

 

[Woodonglass]

Re: 1969 Larson - Big Project

If you mean put wax in the resin... NO.

That is what I meant. And thanks!

Now I just need the wifey to come back with my wallet. Short one part.

Re: 1969 Larson - Big Project

My regular late night update!

Per standard, nothing quite went right today. But we deal. I got the transom all glassed and ready to glue, but for the life of me it wouldn't quite fit right. I had to do quite a bit of sanding and grinding. But did get it!



Transom IN! Sup.

I decided to use a combination of the holes that weren't getting filled and existing holes to create clamps using wood scraps, hex bolts, and washers. I have so much hole filling to do on the outside, I didn't see a need to create a clamp system.



Made one heck of a mess today, this is just a bit of it...



An amusing oops, which I won't duplicate...



I also created something my wife thought was "cute". I can't imagine why:

Re: 1969 Larson - Big Project

Also for the record, in case anyone is trying to learn (like me), here is my materials list for my 62" x 20" transom. Purely so you can have an idea of what it took:

1. 2 yds CSM
2. 8 qts resin (2 gallons)
3. 1 cup 1/4" chopped
4. 5 cups cabosil (thickener)

This of course doesn't include a few foam rollers, sandpaper, etc.

The 5/1 ratio of cabosil to chopped strands seemed to work really well for a good thick PEANUT BUTTER recipe. Part of my above list is the 4 quarts of PB it took to glue the transom in place. It definitely doesn't go far. I would imagine I use probably 5 times as much getting the stringers glued in and set up. We'll see soon!

But like I said, best laid plans...

I'm going to have to fill the holes I made to glue the transom in before I proceed. Shouldn't take long. I should be able to that as well as getting the transom tabbed and glassed tomorrow night. Then it's off to stringer construction!

Re: 1969 Larson - Big Project

I hope you greased your bolts or screws. If not they can sometimes be difficult to remove once the PB has set up. Also, foam rollers and Poly resin do NOT mix. You should be using short nap nylon rollers. The ones with the Barber Pole stripe on them. Were you able to fillet the edges on the inside with the squeeze out?

Luckily I did in fact grease my bolts. I was using foam rollers a couple of times until I figured out that they don't work great. Luckily I was only soaking the transom at that point and not working with the glass.

The PB squeezed out enough on all sides to start the fillet, but I'm going to add some more to finish it off.

Re: 1969 Larson - Big Project



I finally figured out what the "weird foam layer" was... now that I removed it.

Any takers?

 

[avpaulb]

Re: 1969 Larson - Big Project

My "weird foam layer", according to Coast Guard guidelines, is likely for passenger flotation in the event of the boat flipping.

I guess I need to decide if I care or not. Regardless, my foam was wet and rotted, as well as a water leak source in my opinion. Regardless, I can rebuild it if need be.

The "Great White North" messed up my evening plans anyway. Below 50 and fiberglass don't mix.

Tent is holding!

Tomorrow we move on ... hopefully.

Gee I hope not lol .. thats a lot of putty for stringers. You dont need that large of a fillet for stringers.

Looks like foam core ( little squares of foam 3/4"ish thick ) instead of balsa core on your hull sides.

For some reason I think that is probably Structural and should be replaced.

More pics and info needed though.
