1968 Starcraft Jupiter - Rebuild

Re: 1968 Starcraft Jupiter - Rebuild

How about epoxy... Will it stick to bare aluminium??? Not sure myself. Question is, will epoxy be better than 5200 smeared on all of corroded areas?

Re: 1968 Starcraft Jupiter - Rebuild

Yeah I wouldn't do any 5200 smearing on the exterior. JB Weld or similar would be more appropriate.

Re: 1968 Starcraft Jupiter - Rebuild

It seams that everyone is in favor of using Gluvit on the inside of the hull.... why? Because it will flex with the hull. Epoxy on the hull may be too stiff and crack --- which is why most tinny restorations use Gluvit. Would JB Weld have the same issues? Seams to me I remember Jas using JB Weld to hold two brackets together without much success... but perhaps filling holes it is fine. Dunno. Has anyone used Gluvit on the outside of the hull?

Re: 1968 Starcraft Jupiter - Rebuild

Inside the hull, Gluvit and the 5200/alum combo.

Outside, JB Weld or MarineTex would be a good move.

Why? Each kinda has it's own application it's best at, ya know.

Re: 1968 Starcraft Jupiter - Rebuild

Thanks ez and jas. Just picked up some Jb weld. Seems to be the way to go. May need a couple of tubes given the number of spots I need to hit.

Re: 1968 Starcraft Jupiter - Rebuild

Suggestr you only do a couple spots let it set then test for strength. I see mor damage there than I would care to do without advise from someone who knows and repairs aluminum . Is there a local boat builder close. Im fortunate to have a builder and outfitter for aluminum boats a few blocks away. I could copy a few of your photos show it to them and let you know what they say. These guys repair and outfit Aluminum boats for Bristol Bay fishing and crabbing.

Re: 1968 Starcraft Jupiter - Rebuild

PS - that would be fantastic! Thank-you kindly! I will look forward to hearing what they have to say.

I too share your concerns (and others). As bad as it looks, and as many corroded areas as there are, I have been unable to puncture the hull --- even using the sharp edge of a flat head screwdriver. However, as one of my first threads in this project highlights, that cannot be said for the area where the transom brace meets the bottom of the hull. I won't re-iterate the whole thing again, but will say that I have a thick piece of aluminum that will be attached by rivets and 5200 to seal and protect.

I have been doing some additional research this evening and another product came up that seamed to fit the bill nicely... PC-11. It apparently has more elasticity than JB Weld making it better suited to the aluminum hull flexing. It also comes in larger sized tins and is readily available to me. It can be painted over (as can JB Weld), can be sanded and cures in a reasonable time frame.

So to summerize everyone's comments and research to seal holes and to mitigate the corrosion problem areas...here it is:

Inside Hull Options:
- Gluvit
- Aluminum Pieces with rivets and 5200
- 5200

Outside Hull Options:
- JB Weld
- Marine Tex
- PC-11

Check your PM site I sent a name and phone for the Aluminum boat builder It is a large business. You could prob send them the photos of your most concern.

Better yet just go to the boat repair web. site ------Petrzelka Bros. Inc. Mt Vernon Wa.

Re: 1968 Starcraft Jupiter - Rebuild

Ok. Called 3 places including PS's recommendation...all said scrap it. Aluminium swiss cheeses when it corrodes and pits. Better to find a hull that is in good shape and go from there. Not really the answer I was looking for. Better now than later. Just need to find another Jupiter!!

Merry Xmas/seasons greetings to all.

Oh man, I'll go over here and cry now.

Re: 1968 Starcraft Jupiter - Rebuild

IM - That's not good news. On the other hand you don't have a big investment in time and money other than the purchase price. And what you got for the rebuild so far won't go to waste, just store it away. So best to get the bad out of the way now. When you first asked about holes in your first posts it appeared fixable but after you flipped and the pitting was worse than expected, that kinda cooked the goose. On the good side, you learned some about tinnies and the pitfalls - which can only help as you look for another. I'm guessing you are gonna scrap her, don't forget to strip her bare - bow and transom caps, rob rails, windshield, nav lights and anything you can pull off. These things are worth money toward a replacement boat, And the parts could also be used on a new one.

Re: 1968 Starcraft Jupiter - Rebuild

Well guys, I may have spoken (typed) to soon!! I spoke to someone else today and he had some interesting ideas. I am going to chew on it for the next couple of days. Really there are two issues --- hull integrity and corrosion mitigation and prevention.

Question: Who feels that the integrity of the hull is compromised?

Will it last 5,10 15 years more if the correct steps are taken on the mitigation/prevention side.

The swiss cheese issue has to do with removing the existing oxidation and preventing from continuing. Hull strength can get comprimised --- but has it?

I paid 0$ for the boat --- so will it be safe to use for a number of years if the right combination of steps is taken? Is it worth it? It isn't pretty on the hull... but does it really matter as much as I am making it to be?

Just sayin.

Re: 1968 Starcraft Jupiter - Rebuild

I'd save it, but I seem to do things the hard way:facepalm:

Re: 1968 Starcraft Jupiter - Rebuild

Jas... Thanks for having my back on this!!! I mean, how hard can it be?

Re: 1968 Starcraft Jupiter - Rebuild

Im not surprised at the answers you received. Question to me would be How much value do you have for yor family and yourself. Compare it to a Duck if it wals talks and loks like a Duck no matter what you do in the long run its still a Duck.. Only salvation I see is strip it and You can be more flexable in your search if you salvage enough from the one you have. . also and look for another hull. Safety FIRST -------Pugetsound

Re: 1968 Starcraft Jupiter - Rebuild

PS - thanks for your thoughts. Value for the fam... but of course! Is the boat going to disintegrate when it hit waves... not likely. Leak???? Much more likely. So I will look around and find a hull and use this boats bits to fix up another. All best this holiday season everyone!!!

JB Weld for sure. HTS for any thru holes. Brazing is not bad once you climb the learning curve.

A moment of silence. I wonder if someone used a anti-fouiling paint on the bottom, something with copper in it. There may have been a reaction between the metals.

You can get another hull cheap. Good luck.
