Thread: Puddle duck in the UK finally starting!!

Well Mr. Snail I should probably leave answering your question to the experts however with a forum name like that I can't resist.

No stability will not be affected by a heavier foil but a pretty foil is important cause the duck needs all the help it can get.

Have fun
Mike

Howdy!

It will be heavy if made of beech, but that is only inconvenient when handling the board/s

I am not sure how well beech glues.

Mik's just jealous coz we gotta make ours out of cheap pine

I'm really doing this! I've started!!
The wood in the UK is completely different from everyone else but I managed to get some marine ply 4mm and 6mm, unfortunately I could only get 3 ply. The 5 ply was only available in 9mm thickness! So I may regret this later. I had to pick it up in my car as they wanted to charge me delivery!Attachment 120409
I managed to use the schools workshop and cut the pieces ready for making the foils but now we're on holiday I have to use the garage. Good in one way, because I have time to play but unfortunately wont have the tools.
Attachment 120412
I spent two hours yesterday marking out and today cut out the pieces ready for gluing tomorrow. Unfortunately the glue is on order and will come tomorrow otherwise I'd be in the garage now gluing! especially seeing my wife is watching "strictly come dancing" on TV!!!
Attachment 120410
In my lack of space and enthusiasm I laid all the ply sheets on top of each other.Why oh why!! looking back now it was so stupid!! You guessed it! On cutting one of the sheets I felt a little more resistance than normal and realised I was cutting more sheets!! The 6mm bottom.
Attachment 120411
The image isn't brilliant but its approx 5mm from the edge and 210mm from the end of the sheet.!!
Will I need to buy a new 6mm sheet? Any suggestions welcomed.
Thats all for now. I'll keep you informed of progress. Its not as good as AlexN WOW!! but its in the UK!!

Hi Animatedsnail,

You won't need a new 6mm plywood bottom sheet because all the edges glue to at least 19mm of solid timber and the edges of 4mm ply sheets ( chines on the sides and transoms on the ends ).

The glue / filler will fill the cut so it won't even show, and it won't have any effect on the strength either.

We all make mistakes, have accidents etc., half the "fun" of building your own boat is finding out how easy it can be to make it look perfect while correcting any problems ( having a cluttered workspace increases the chance of making mistakes / having accidents etc. ).

Most importantly, try to have fun, don't worry too much, and good luck.

Speaking for myself, I only make improvisational design enhancements....

...half the "fun" of building your own boat is finding out how easy it can be to make it look perfect while correcting any problems.

I am doomed... Correcting mistakes or accidents or whatever else we want to call them is one thing... make the correction look perfect is not going to happen. I do not have the skills to make things perfect. I also do not desire a flawless boat. To me, a "perfect boat is not some highly detailed showroom diva. The "perfect" boat is one built to be used without apologies. Upon reflection... perhaps I can build my perfect boat.

( having a cluttered workspace increases the chance of making mistakes/having accidents etc)

I am doubly doomed. Clutter defines all of my work spaces - the kitchen at home, the "shop" such as it is, my desk at work. I'd go stark raving mad without the clutter. Some might say I am already there.

Bob

Clutter? Who works in a cluttered workshop? Not me. I can still move around the boat ... mind you, I have to squeeze past the transom though my strides get caught on the vice everytime I try, and the bow is hard up against the shelves, and the saw horse supporting the starboard side is hard against Sixpence so you have to climb over it after making sure you're facing the right way because you can't turn around between the LBD and Sixpence, but you can walk down the port side ... provided you turn side on and weave past the end of that sawhorse

I thought I had better give you all an update of how things are going. Thankfully, due to being on holiday the duck is now 3D!! Unfortunately I have had a few problems!!

I decided to use Titebond III to glue everything together rather than epoxy. But I think that it hasn't glued as well as I had hoped with a couple of the joints being weak! When I fillet will ths strengthen everything, and if so, what would you use? Is epoxy the only way!!!

The other problem I had was that on e of the sheets of ply has de laminated in an area 100 mm Square!! Should I again try to put some epoxy behind the first laminate?

Anyway, Some pictures of "Peking" duck (does anyone else have that name?)

My baby!!

IMHO the only glue that adds strength in any appreciable way is epoxy with a strong filler. Certainly the PU glues (like titebond 3) don't do any good as a fillet.

Generally the titebond is pretty good at flat pieces of timber to flat surfaces if the clamping pressure is OK. So most parts that were glued on the flat will be OK if the clamping pressure was enough

The places I would look at reinforcing with epoxy ...

Regular epoxy gluing - mast partner and step fully glued with epoxy and the right high strength filler in the glue. Centrecase to bottom join and the crossways floor stiffeners to bottom.

Fillet - the cockpit front bulkhead to cockpit floor, the side tank faces (as per the plans).

Glass tape with epoxy - outside of the chines and the bow and stern transom outside corners.

I think that would resolve any potential problems without undoing any structure.

If you don't plan to use epoxy at all then get back here as there are alternative strategies of using some fastenings in some places and glass tape with polyester resin - but epoxy is the easiest and safest way to make a super reliable structure.

MIK

Thanks MIK,

I've bitten the bullet and gone and ordered some West Systems epoxy. I know I should have listened to you in the first place!!! Would you use the epoxy thickened even for gluing the surfaces or just for the fillets?
Thanks

Hi Animatedsnail,

I use 'bote cote' products which specifies for gluing use 1 part glue powder for each part of both resin and hardener combined, for filler use 2 parts glue powder for each part of both resin and hardener combined.

'West Systems' should be at least similar, check your instructions that came with the product ( if any ) to be certain, or someone else here at the forum that has used 'West Systems' may just confirm it for you any way.
