The front and rear parts of the keel are NOT glued together. There is a gap for the prop tube. If you align the ends of part 4 with the slots in the keel parts then this should give you that gap. Make sure that the keel is dead straight along its bottom edge when you join the two ends to parts 4. Here is a picture of a similar model which shows what I mean.

I take it that you are aware of Bluebird's excellent build log of the Swordsman? Have a look at Reply #2 here  http://www.modelboatmayhem.co.uk/forum/index.php/topic,7668.0.html, which shows how John did that part of the job. It's always worth having a look here first as it could save you time and trouble if you aren't sure about a procedure.

Hello Guys

I ask before if I could use Balsa for skinning the Hull of the Swordsman. 2.5mm cover with fiberglass cloth would be enough I think but i was thinking, If I would Use 3mm liteply will it add too much weight for this model?

Hi there
the original model was built with, I believe, two or three mm thick lite ply skin.  To be honest its that long now since I built the model I cant remember now.  Technology has moved on leaps and bounds.  There is now new Epoxy Resins which are water-based, along with light weight materials would be ideal to skin the hull over the top of lite ply or balsa.

I have built similar models recently to the Swordsman and used the water based resins which are quite good (by the way the resin is Deluxe Exe-Kote which I used).   I also used the light weight woven roven matting which is the one some of the Aircraft lads and lasses use to skin the wings - its the lightest of the light of materials and it went on really well.   More like a lightweight silk.

To build or do over


Part I


Newbie builder and poster.  Am from Arkansas near White River.  Have started lots of model boats before but never got over the hump.  Have a lot of half built hulls in shop.


Part II


Found Bluebird's build log and ordered Dave Milbourn's plan to build Fairey Swordsman. Plan makes sense. Bluebird's build log makes it look easy even for me.


Part III


Materials here are not generally available at Wal-Mart.  I reached out to HobbyLobby across the river. They have "craft ply" in 1/8 inch (3ply basswood) to take place of 3mm lite ply and 1/16 solid basswood sheets to suffice for 2mm.  Using available materials I built up keel, made chip board templates, sanded ever so carefully, only to find out.....


Part IV


My carefully crafted keel will lay flat on one side but on the other there is a bow of anywhere from 5mm to 12mm; hold the stern to the table the bow tip is 12mm off of the table.


Part V


1. Do I go go ahead and build it up for experience?
2. Is my wood sorry?
3. Is there a wrong way to clamp glue laminates?
4. Would 5 ply birch lay flatter?
5. Other suggestions.

Hello , it seems a shame that no one has replied to you, so here goes, for what its worth.


I'm a bit puzzled how your keel can lay flat on one face, but not on the other ? (I assume you mean that it lies flat if you put a 3mm chock under each end , given that it is joined in the middle by a lapping piece of (if memory serves) 3mm (but then this is assuming that you have joined the fore and after pieces of the keel, which may be invalid assumption)).


However, even if it does have a bow/warp, you could do things like pressing it flat and gluing some doubling pieces along its length, and leaving it to dry under weight / pressure. Make sure that the surface it is lying on is definitely flat. By the way i don't mean to patronise you here, so apologies if you have already done this. But probably even if you left the warp in, it would straighten up OK when you glue the bulkheads and stringers in place, as long as you have it pinned down over the plan to make sure that the bulkheads are aligned while it is drying. Probably even then if the keel was a bit squiffy, when the hull skin is put on , you can sand the liteply so as to get the keel line as exposed to the water,  straight. I must get on with mine, i have a hull and decks but no superstructure. 


Cheers.

Soak your keel in Ammonia then lay on a truly flat surface with another thick board  (Timber ) and load it with as much weight as you can. Old Irons (smoothing ) are good but tinned goods books rocks anything heavy. Leave a week to really dry out. Lt should now be flat. If not make a new one. In one piece if you can Suitable resin bonded ply should be found in a builders supplies yard. Often Offcuts are available. Good luck :}
