Gary Findlay 1/16 U7 Notre Dame

[Liam Hickey]

Hi guys, just wondering if anyone else has built this model? This is my first ever build. I've cut all my parts out, however the trouble I am having is some don't seem to fit correctly, for example there is alot of overhang on the front stringers, and the sponson runners, meaning they will not fit together. I this a normal thing? Like they need to be trimmed considerably to suit.

Appreciate any input, at this point I'm just going to start making it up as I go.

Pics to come if anyone is interested.
Cheers
Liam

I've not personally built that boat but, having built a lot from plans, I always make sure to oversize all of the parts EXCEPT the sponson insides, engine bay side bulkheads and transoms. The reason I oversize everything else is so I can sand everything flush so that the skin panels will have a smooth framing to be glued to and it eliminates the chance of parts being undersized or having to remake parts due to cutting or lay out errors

Thanks mate, still learning here. Can you advise if you usually bevel the joins on outside edges (sponson side to Runner for example) or lap them ?

If I can get them to post, here's a series of pictures of the sponson build on a redesigned Dumas Pay'N Pak I built several years ago:
This first shot shows the framework as it initially was done. As can be seen, I added a 1/8" square glue block to the outside of the sponson chine but, at this point, nothing really lines up well

In this picture, you can see the framing was sanded down so that everything is flush. I also added a larger glue block at the front of the chine to give more area to epoxy the sponson side to

The third picture shows the sponson side added. What you can't see is that the frames were sealed with epoxy first to protect them from any water that might get inside the boat. Something else that is visible is that the bottom of the side panel has been sanded flush with the framing so that the bottom will lay flat on it, eliminating any gaps and keeping the bottom smooth.

This last shot shows the bottom added and sanded flush on all edges. It also shows the deck installed from the under side with how much overhang there is past the sponson sheer. Two things I can't stress enough is MAKE SURE THE BOTTOMS ARE INSTALLED WITHOUT ANY RIPLES OR NONFLAT AREAS AND DO NOT ROUND THE EDGES WHEN SANDING THEM FLUSH!!!!! Either one of these will suck the boat down and/or keep it from planing properly[IMG width="587px" alt="Click image for larger version

That was interesting, one picture posted and the rest gave links. Hopefully, you'll be able to open them all

Thankyou very much Hydro junkie, I appreciate your effort to show me, and great advice. This really helped clear a few things up. This week I am really busy but next week I will make a nice flat jig and start assembly.
Will keep updating with as I go.
Thankyou kindly
Liam
