Re: 1960's Starcraft Something or other

Well if using all aluminum rivets means I don't have to dab every rivet with sealant then I'm definitely returning the ones I bought lol..I'll pick up a pack of all aluminum. Hoping to start riveting Sunday! Yaaaaay!..

P.s. I $&@%ing hate stripping paint lol

I would dab the aluminum ones too, it sure cant hurt, leaks suck, especially with all the work you are doing.
Nice steelie BTW, what location produced that baby?

He's using closed end blinds so the 5200 would have to go under the heads and in the holes if through the hull that's always a good idea.

Re: 1960's Starcraft Something or other

I think i'm going to return the aluminum/steel ones and go all aluminum, ill use the 5200 cause i agree, leaks suck! Regarding the back up washers, when and why would i need them? i bought them cause i know people recommend them on rough rivets. I was planning to do more stripping but with the 70-80km gusts today i didnt feel like playing around with instaburn stripper. Tomorrow work continues.

Re: 1960's Starcraft Something or other

I only use backer washers if I have rivets that are too long or when riveting wood to aluminum. Otherwise they don't serve a purpose since your drilling a 3/16" hole in aluminum then popping a rivet in the hole. All the backer would do is add more aluminum to it but it won't hurt either.

Bullfrog rivets are steel mandrel too and people use those for blind repairs of through the hull rivets. In your application solid rivets would be best for repairing the seam rivets although blinds will work and so would say #8 stainless machine screws with nylocks on the inside. Looking at your seam area, it looks to me like you have some suspect rivets beyond the PO's screwed up mess that could be leakers due to impact and wear so look them over.

The best of both worlds are stainless rivets, strong and won't rust out. They just cost 2 or 3 times as much is all.

Re: 1960's Starcraft Something or other

Wow thanks for all the info guys!..I went to brafasco and couldn't get a refund for the rivets and they didn't have all aluminum so looks like I'll have to use them. The guy I was dealing with seemed a bit like an idiot so I'm going to go to another location. I'll look and see if they have solid aluminum rivets as well. Tonight I'll have some pics after I clean up the hull and get the trailer back together so I can check for what's leaking..

Well people it's done..stripped..cleaned..naked..and part of me is wishing she would put her clothes back on.



She looks good far from, but unfortunately far from good. The PO is a real piece of work and I'm not sure wether to go and pop his tires or not. Double sad faces any suggestions on what direction to take now?. Besides the scrappers.





It goes all down and around the centre seam :S

Please tell me that they aren't rivet holes filled with silly-cone?!

Mikey - Back up some and grab a few more pics down the center. I don't know what's been done to her, but the keel is not sealed. It looks more like welds to me. De-painting would have cleaned silicone off.

Just found this thread, welcome an other Kanuck to the fold. Those last two pics don't look good at all.

Re: 1960's Starcraft Something or other

eek 5200 maybe? Looks to have a smeared texture to it, rather then a welded seam look. But I agree, paint stripping should have loosened most types of caulking....

old autobody lead work?

Re: 1960's Starcraft Something or other

It never ceases to maze me how people think they can fix a leaky boat from the outside only. That bead of stuff looks like cured 5200 to me and it's pretty much impervious to solvents and strippers. Try eating it away with a wire wheel, it may take some time to get it all off but I don't see any other way.

Re: 1960's Starcraft Something or other

Re: 1960's Starcraft Something or other

I took some more shots for you guys. Unfortunately it's not sealant or 5200 at all. They are welds, flat out idiotic welds. Here's the gore.











The scrapes are from me and the scraper. Heeeeeelp!

Re: 1960's Starcraft Something or other

Re: 1960's Starcraft Something or other

The rivets were replaced w/ plug welds? WTH?

This still looks like something other the welding:

What's smeared along the seam & between each welded rivet?


Along that keel strip there should be a couple 3/16"+/- weep holes. They are intended to let any water the gets into the keel strip to run out the weep hole rather then staying in the keel strip. I couldn't see them in any of your pix. Are they still present or have they too been welded closed:

Depending on what's between the rivets, and whether the weeps have been closed too, my suggestion may change. So what's the stuff between the plug welded rivet holes?

Re: 1960's Starcraft Something or other

I thought those were weld puddles. :facepalm: Time to go spike his tires! Well, no - Don't get carried away even though it's tempting.

Mikey, I think the hull has to be flipped right side up to see what other joy is inside.

Re: 1960's Starcraft Something or other

Re: 1960's Starcraft Something or other

Since they are welds only one thing to say... glad it's the bottom and nobody will see them again once flipped right side up.

Re: 1960's Starcraft Something or other

Re: 1960's Starcraft Something or other

Haha cosmetically I'm not worried but what am I looking at here structurally and in regards to leaking. I can't flip the boat over at the moment cause I'm by myself but I looked underneath and there's no penetration of welds through the hull that I can see from the back.

Here's a close up of the JB weld museum



And unfortunately the weep holes are welded shut :S





I think I'm close to the point of being done with this boat.

Re: 1960's Starcraft Something or other

Re: 1960's Starcraft Something or other

I wonder if the goof with the welder did all that overhead welding even had a clue what he was doing. Chisel the JB off, wheel it clean and see what's under it, I've seen worse as far as the JB weld and keels go.

Evidently the welder dood thought that the keel chine was a part of the boat that would leak and that it wasn't just riveted on the bottom. (I wish SC would have riveted on the splashrails rather than made them into the hull.)

No sense in giving up over cosmetic stuff, get rid of the JB, drill out the weep holes and when you flip her back over do a leak test to see what's up before throwing in the towel.

Re: 1960's Starcraft Something or other

Re: 1960's Starcraft Something or other

Yeah my earlier frustration was just driving me to the edge..I did some more work, bought some stainless wire brushes, mineral spirits and went at her.





I managed to get my brother over and we flipped her on the side so I could get some shots for you guys. Some rivets are still visible, some are welded over. Putting the trailer back together tomorrow and doing the leak test. Still on the fence about her though.

Re: 1960's Starcraft Something or other

What the hey! Did the PO drill rivets and tack her together? I'm about ready to agree about spiking his tires. And taking the BFH to his welder. And his fingers and head while your at it.
