Double Plating Question

hi check my pic how we did it

Welding

Ok yes it does look good. We welded with mig-welding inside and then stick with conventional welding outside.then polished welds, but we wore them on the outside pin hole, you can always weld again

Outstanding!

No Epoxy repair

I am a materials engineer and have seen the epoxy repair systems that are used for water lines. This stresses the epoxy experiences are all in compression, so the bond strength between the steel and epoxy are not critical.

For your boat there would be shear stresses as the hull flexes and could cause delamination.

I would also recommend cutting and replacing. Make sure to use the proper grade of steel plate, usually corten or equivalent.

And how much experience do you have with steel and epoxy?

Can you provide a Spec Sheet for the Manufacturer who endorses this as a surface preparation ?

Would these stresses be any different to any other Steel boat?

You might want to add that any steel plate cropping and replacement should also not only utilise the correct grade but the correct thickness and approved welding procedures/materials should also be used.

Why does it seem like this forum is a rabid display of constant oneupmanship? This display is not entertaining, or welcoming..

Yeah, let's get back to the original topic and what came from that.
545X you've had almost had an entire month off now; back to work!

Keep us updated with the process. I realy enjoyed it and would like to see the remainder of this roamer restauration docusoap too!

Agreed. It certainly detracts from the otherwise wonderful content offered here.

I really don't think the points raised by K1W1 were a case of 'oneupmanship'. He's trying to steer you in the right direction based on a high level of experience in building steel and aluminum yachts. I know K1W1 personally and while I'm not at liberty to divulge his identity, please trust me when I tell you, we are lucky to have someone with his expertise here. If he's taking time out from a very busy build schedule to join in the Roamer discussion, then tap into his knowledge!

Lucky to Have Them on YachtForums.com

Carl,
Basically ditto on the above.

While I haven't visited him recently as you have, he has never failed to jump in and help me (both publicly and privately) on engineering related issues no matter what kind/size of vessel I have been on at the time. We are fortunate to have extraordinary talent like him (and Marmot) on the forum.

While sometimes a little gruff on the initial replies on the general forums (usually as a result of vague questions, or someone spouting off inaccurate advice/information), the results are ALWAYS worth sifting through the answers once a concise direction is established.

Just my $.02 (American)

ROCKY

Gruff! Good word and a good description Rock. Let me share something with the Roamer contingent... I hosted the CC Roamer forum for Eric because the boats are steel and aluminum, therefore the materials and procedures cross platform to the other yachts we cover on YF, giving our Roamer members a diverse source of information and experience to draw from.

On Marmot; I haven't met him, but I know who he is and what he does. This is the guy that 100's of captains and chief engineers rely on when they can't come up with an answer. We are privileged to have him participating on YF! Yes, he's a little direct because he doesn't have a lot of time and actually has more important things to do. If he sees a glaring inaccuracy, he calls someone to the mat. I'm willing to bet it's the reason that most of us return to YF.

And finally... we're all grown men that are dumb enough to own boats, which means we subject ourselves to far more problems than the average human. On this basis alone, we should be more thick-skinned than most. Let's set aside diplomacy and get to the point... YF was founded on answers. And that's FAR more than most forums offer.

BTW Rock... I still wear my IBEX shirt proudly!

545X - the black makes for one mean looking hull. Looking forward to the completed project. What does the boat weigh?

As far as the oneupmanship, I love to see the experts go at it - think of it as a fight in a hockey game.

We need to meet up!

My 1963 36 aluminum with flybridge,gear, and full tanks is about 14,000. r n
