I'll have a look at them and post on the forum if no good so no falls into the same trap. in hindsight I should just have have used the ones I took off lol

Plywood delamination

HI I built a firboat from plans from that guy on eBay. The templates where useless and I had to redrew most of them from scratch but I got it built in the end.check the templates first before you cut wood.

HI Dave
Hope you have a good one at your gathering it's all a little sparse done in the south for things like that or I'm just not looking properly.
I've found a guy one eBay who's selling instructions and paper templates for the crash tender for 15 quid - shoukd be here 23rd so will let people know what they're like.

HI Neil
You should be Ok with the 2.5mm. its not carrying any weight and will be easier to cut to shape and the windows will look more realistic.
My model had the original metal frames and you could fabricate from Litho plate. Not seen anyone selling the part tho.
I have provided others with templates for tyhe windows and will look up the file and let you have a copy. Just off to the Ship Modellers gathering at E Port so in a rush at present. I'll sort out tonight

Plywood delamination

HI Dave
Thanks for your reply and I've managed to have a good look at the plywood superstructure and it turns outs there was quite a few areas that have delaminate even to the point of crumbling. With your words in mind I attacked it to the point where there is no deck or superstructure on the hull now. it was pleasantly pleasing but now in a position where I'm asking myself why did you that. However all the glue was so brittle it came apart easily. I bought some 2.5mm plywood to make new side pieces but think it should have been 3mm? Also is there anyone on here that can make or sells the side window pieces? I'm not sure whether I'll manage it with the limited setup I have. I will set up a boat blog as suggested.
Cheers Neil

HI Neil
If the ply has deteriorated to such an extent I suspect it will crumble when you start sanding. As Mark says Cyano will seep into the layers but once the inner layer is exposed it is very prone to crumbling and once its gone there is nothing for the cyano to fill.

You have not said which exact part of the window area is damaged but I had a similar problem with my Fire tender and having taken a paper template I made a new piece from ply of the same size and replaced the damaged bits. Glad I did because the areas that looked OK were all crumbling inside.

Might take a bit more effort but better to solve now than when you start to rub down and paint.

A build blog with pics would be of great benefit and help to other members who may have similar problems.

Good luck with the restoration

HI Neil

Try using thin cyano, dribble it into the splits then use spring clamps to close up the damage. the glue will sink into the wood and is easy to sand, if you have a lot of damage go to the pound shops, they have tubes on a card, 10 I think, so your not opening a large bottle, do it bit by bit.

Plywood delamination

HI all
My fire boat has not been best treated as it's sat in a damp garage for over a year and even though there's loads to do to get it going I've noticed the plywood on the window area of the superstructure is delaminating. What the best glue to use that will accept paint and able to be sanded down if needed. Dont really want to use normal wood glue as have had issues in the past when painting over it. Any help would be great
