Help on saving a (ruined?) bounty launch model

[AlfredoCampos]

I've just started my second build - bounty launch by occre - and i think i already ruined it.

 

If you look at the first and second pictures, you'll see that the line doesn't connect with two bulwarks. I read it happens and that you need to add a sliver.

Then i passed a line on the other side and saw that its NOT the same bulwarks that arent' connecting (third picture).

Well, the fourth picture shows they aren't in line.

 

And the fifth and sixth show i clearly glued several bulwarks with slight (or more) angles!

AND i also managed to bend the keel...

 

Finally, the bow bulwark protrude from the false keel, as is in the instructions. BUT they should be lined yet the second is lower.

 

Can any of this be solved? Or have I ruined the model?

I read that it can be unglued wraping the parts in a tissue enbedded in alcohol for a day.

Or maybe using a load of filler?

 

Anyway, how do i make sure bulwarks are perfectly leveled/perpendicular to the false keel?

 

Please help, any advice to save the model will be greatly appreciated, it was a birthday present from my wife

You might be able to shim the frame to build it up enough to work?

What did the instructions (if any!) say to do? That might help us help you.

To me it looks like that some of the frames aren't in the correct location.
It has happened me that the plans vs. the bulkheads aren't labeled correctly.

I would double check that first.

Good luck.

Before shimming frames that are too small with thin sliver of wood, I would first make sure that the keel is PERFECTLY straight (yours appears to be bent - see the pic) and all bulkheads are PERFECTLY perpendicular to the keel and only than I would check everything. Also, if your plans show the bulkheads profiles, check the wooden ones against those paper profiles and make sure they are the same and symmetrical.

Sometimes kit manufacturer's cuts are "less than perfect", and the parts do not match their plans.

Assemble your 'skeleton' in a mounting jig carefully, before you proceed further.

I don't think it's ruined and is probably a fairly easy fix. The frames do look like they could be out of order.  I think @Nirvana has a good point and that would be a good place to start.  It is hard to tell from the pictures if the frames are really square or not, but they don't appear to be too far off.  The easiest way to square them is to hold them in place with something that is perfectly square.  I use legos.  It also looks like there is a lot of char that has been stained over.  Make sure everything is beveled properly and that may help as well if the frames are in the correct places.  If all else fails you can shim up the edges of the frames. Just be very careful to make make it look nice since the frames are visible in an open boat.  As far as removing the frames, a small paint brush with isopropyl alcohol and a hobby knife can actually separate them more quickly than you would probably expect (assuming you used PVA glue).

I think the two frames in front of the transom are swapped

You are all very helpful, what a wonderful community!

 

From your comments, this is what i'll try:

 

1) Yes, the keel is bent, already confirmed it. Will try to build a jig, apply some steam and try to fix it in position.

 

2) will unglue those which are clearly not square and place them again.

 

3) all is as in plans, i numbered the pieces before removing and just checked.

 

4) i'll unglue the 2 after the transom and recheck. Either the plans weren't right or i numbered them wrong.

 

Will keep you updated, thank you very much!

Good luck with your do-overs. We have all had that happen to us - often repeatedly!

From the photos it looks like part Nos 2 and 10 are not square fore and aft and 10 is also not square port/starboard. The rest I can't tell from the photos, you will have to check them.

The keel needs to be fixed, 10 needs to be fixed, 2 should be fixed. All frames appear to be in the right positions. Fairing should fix any minor out of square issues.

Pardon my ignorance, in your first picture, what do the purple squares you drew mean?

Sorry, it's just a simple way of showing if the frames are square to the keel. Using this method,  because of the distortion caused by the camera lens,  8 and 9 can only be checked where they meet the keel whereas 10 is close enough to being square to the camera to be checked for it's full height. The second photo is more obvious, the green lines all slope down from left to right but the purple line slopes down from right to left, clearly different.

 

The distortion is why we can't be certain what is and isn't square from your photos, we can give opinions but you will have to check yourself.

 

If you don't have a carpenters square to check with (or yours is too big), these days lots of paper has very square corners. Photocopy paper, business cards, appointment reminders from your doctor or dentist etc. Probably even birthday or greeting cards.

Thank you very much, got it!

I'm jumping in a  bit late to this.....  as far as the keel bending..... make sure the bulkends fit onto it with minimum resistance.  A tight fit at the "notch" will warp a keel real fast.
