Epoxy resin

[kiwioutdoors]

I am looking at restoring a dingy that belongs to my father in law. It quite old and the ply is a little stuffed in some places. I plan to strip it with a mix of scrapers heat guns paint stripper and sanding ( not all at once lol) Now for my questions

1 Is it ok to seal and fill with resin without using mat?
2 I may have to make a few replacement parts do I need to use marine grade plywood or would pine providing I seal them do Itd kept in a garage and used a couple of times a year
3 What kind of paint is best? can I use house paint.

Thanks

will post photos of my progress

Howdy Kiwi,

Have a look at my FAQ on
http://www.storerboatplans.com

(see it listed in the left margin. It will probably answer a lot of your questions about sealing, gluing etc.

But in general you don't necessarily need to use glass and if you did you use woven cloth - not chopped strand matt.

In the nicest possible way Mik, as good as your FAQ is, it sought of defeats the idea and spirit of a forum in my opinion if you just direct every question to it rather than letting the forum contribute.
There are many opinions out ther on a lot of things regarding boat building and I would love to see people able to contribute rather than have all questions referred to a book of FAQ's by one person.
I mean this in the nicest possible way and I am of course open to critisism on my views.
I hope this comes across the right way.:)

Without going to Miks FAQ ...

1. Depends on what/where but yep. Didn't use any mat on the Cadet. The rainbow will need a little around the centreboard casing.
2. As long as you seal it, suggest getting the TRPDA (like a thinner for poxy) and use that to be really sure. Oh and make sure the boat is drained and well ventilated when stored coz moisture can do a lot of damage if left to its own devices:-
3. I used good quality house paint on the Cadet and thats used most weekends.

but read Miks FAQ for more info or hit us up here :2tsup:

Mik does that coz there is so much to cover even when it appears to be straight forward. He'll be alright, he won't take it the wrong way... At least after he spits the dummy, tosses the teddy, kicks the dog ..:o:q:U:U

I don't that's an unfair comment scotty, but I'd also like to point out that if it hadn't been for Mik's response, kiwioutdoors would still be waiting a month later.

So often the basic advice is easy to get if you know where to get it, and Mik's FAQ's are a really easy way to take the basic stuff on board.

I think it's far more productive to read the FAQ's first, then ask any questions one still doesn't understand or ones that are specific to that project. No point in reinventing the wheel!

I assume kiwioutdoors got all the info he needed, because he didn't come back, and I reckon that's a ringing endorsement for Mik's action.

No, I'm not defending Mik, I often respond to technical questions on other forums by referring to manufacturer's web pages, or technical references, (including WEST'S data sheets by the way)!

Cheers,

P

Howdy Scotty,

I can see what you are saying - but I don't think it is true. For example if anyone posted a link to my FAQ in response to someone elses question there would be no problem.

Or a link to anyone else's FAQ.

Also I think the way that questions work on the forum is in two ways.

Some people just love the forum process and others just want answers that solve a problem quickly.

I don't always jump in with my FAQ straightaway anyhow - in this case it did happen because from the way that kiwioutdoors is asking the question he hasn't had much or any exposure to boatbuilding or the materials involved.

Anyway - why don't you write a reply ... and get the forum process working the way you would like to see... I'm sure you have something to contribute on this.

There are lots of things my FAQ doesn't cover and also some decisions that the fellow needs to consider.

Does he want to fix the boat up really well or simply get it going?
How badly is the plywood damaged?
What sort of boat is it?

Also I didn't answer his specific questions but sent him to read some material for an overview.

Go for it ...fill in some more details or expand the conversation into other areas ...

Actually Scotty,

I can see part of the point of what you say.

What I should have done (and would have normally done) is to write a little preamble about my biases and to point out there were other approaches as well. I will try to be more careful in future.

So here goes ...

My bias is always pretty well at one arm of the "spend the monay and fix it properly" line and if glue is involved in the existing structure then I will generally advise about going the full epoxy hog if the boat is at all precious to the owner.

But with trad construction I would much rather see the boat continue as a trad boat unless there are significant issues with hull strength.

With the particular boat we are talking about here there may be a good case for a minimal repair job if it is only important to keep it going for another season or three.

And there needs to be some discussion about what the "stuffed" plywood means.Some pics would be good.

Best wishes
MIK

The other issue Scotty, is the time involved in typing out the same answers to the same questions time and time again. It's like the old 'do a search' response. As long as the poster (in this case Mik, who does do this) is willing to follow up any specific questions not covered by the FAQ/search/whatever, I don't think it's a problem. It's always nice to get a detailed, personalised answer to your question, but bear in mind the poor bugger who has to type it.

Firtst of all, sorry to Kiwi for hijacking his thread.
To mik and the other guys, fair points all round, taken on board. Once again no offence intended Mik and it doen't look like you haven't taken any.
To prove one of the above points in reply to soap box session above, I don't have any time at the moment go into much more!
Scottyk:)

[Boatmik]

Howdy Scotty, I was a little inclinded to be offended then thought better of it! I know you as a good fellow and good contributor to this forum.

Thanks for bringing up your thinking without fear or favour!
