Cyanoacrylate & steam
Hi all
I have built a fishing boat plank on frame using a water resisting wood glue and I found that it took quite a long time putting just 2 /3 planks on and waiting for the glue to dry this is ok when you’ve got other things to do :rolleyes: BUT I now would like to build a Clyde puffer but I have a time limit to plank the hull. :( (we are moveing house soon)
I have noticed that some builders are using cyno glue to plank with but the pack instructions say that the surfaces should be dry :confused: but I need to steam or soak the planks to bend around the bow and stern so they will be wet :(
I was going to cyno the planks on then paint the inside with watered down wood glue then when dry epoxy will this work :confused:
Please advise on the quickest method to glue the planks on.
thank you
regards to all

well I have tryed cyno to stick the planking on....................... :eek: got the d stuff all over my hands all over the building board on my shirt, but the planks did not stick to the formers :mad: :mad: :mad: but my fingers stuck to every-thing :o please help!! I am struggeling to type this with the one finger that i have left un-glued, and the way I feel at the moment I just may throw the lot into the bin :( and take up knitting insted. :rolleyes:

If you can knit me a destroyer, I'll send the wool by first class post!

I think your best bet is to leave the idea of planking for when you have more time, and go for a different method of construction for this occasion. ABS or glass moulded hulls are quickest, followed by built-up slab balsa carved to shape. Or a hard chine hull to give four planks only?

Not to be a bragered but I have built ( 6 ) six plank on plank useing cyanoacrylate glue thick 15-30 second, I do not use the thin 1-3 second, this glue will work with steam just rag off most of the sweat and the glue will grab a little bit faster because of the heat. Here is a pic or two of the project I am working on, its not do yet but I've not had a problem with this glue. However you should use this glue in a well vented area !! :)

Hi
Ropanach thank you for yur reply
can i ask do you just put glue on the planks where it touches the formers or all along the plank where it touches the preveous plank?

Pete-
CA actually REQUIRES a tad of moisture on the surfaces in order to kick… but sometimes, there's so much air in the joint and the porous wood, that it still won't… or it just takes a little longer. Two ways to fix that- "kick" it with a pinch of baking soda (!), or a spritz of commercially available CA accelerant. I often use a small syringe to apply the accelerant.
I'd suggest glueing the planks to the frames first, then coming back and running a bead between the planks. If you've fitted them well, then use a thin CA to wick in between, otherwise a thick bodied gap filling product.

PATMAT2350 is right about the glue, and yes glueing the plank to frame first and then go back, but wile you glue try to keep the planks as close toghter as you can. LOL,

If you use CA glue for construction and plan to use the boat in the water be aware of the fact that CA glues are NOT waterproof. I'm a Dentist and I can't count the number of times someone has tried to repair their denture with "super glue" and within a day or two it falls apart. If you use it for building, and you intend to use the boat in the water, you must use epoxy or other waterproof adhesives to fix the joints.

Pete,
CA glue will work for planking, as you've been told a number of times already. The 'smart' way of doing it is to just use the CA to tack the planks to the frme, then glue with epoxy or your choice of water proof glue. Then water proof the whole thing again. It does add weight, but if done carefully, not that much (the water proofing, I mean). CA glue isn't the best idea if there is a lot of vibration or flexing of the glued parts, it's fairly brittle.

PS - I like CA! Not much patience, you know...

When building a static model where you want to see each plank wood glue and patience are the best way to go. However if the model is a running model Thick CA to glue the planks to the ribs, Do Not glue between the planks with the CA as it is murder to sand. If you have to, glue from the inside, once you have the shape to how you want it 2 coats of polyester resin with 1/4 oz fibreglas cloth will give you a very waterproof hull that is quite strong as well. It doesn't hurt giving it a coat of resin on the inside as well as it stops stuffing tube lube or electric bearing oil from soaking into the wood and ruining the hull.

Just my 2 cents.
