Why use an old Xacto? What is the benefit as opposed to a new (very sharp) blade?
sorry. i was using a colloquialism. Of course you must use a very sharp blade. Dull blades lead to cut finger.
Hello, who makes this jig pleaseI too, like Brian use a similar tool. I've tried the soldering irons with the adapters and molds and soaking and clamping to the hull. I take a contour tool to get the shape of the hull then "eyeball" transfer it to this tool.
I've found that this tool will handle any bending job I give it.
As far as how well it will do the job really depends on 3 things, thickness of the planking, wood type of the planking and finally the severity of the curve in the ship's bow. Softer woods are more malleable, harder woods less so. I've never had any trouble bending even 90 degrees over a 6-10 cm ever. I have had to soak harder woods longer in hot water, up to 60 minutes. BUT the aspect of this tool that I love is, depending on the width of your planking, you can bend up to 6 planks at once AND it is a passive tool!!! Unlike other planking tools that you have to actively work. Once you put your planks in this tool and wait for them to dry, you can get back to doing other things on your model. I'd rather put 6 planks in this thing and go work on something else for 2 hours than sit there for 2 hours bending planks
Also, if you don't want to wait for them to air dry, you can hit them with a heat gun or hair dryer to speed things up. But I rather let them air dry and work on something else as we all know how monotonous planking can get.

I am sorry El Capi but I would like to correct a little the difference between chemicals structures composition of wood.
- Cellulose : cristalline frame, the skeleton. Give flexibility strongness and other properties to wood. More White the material is, less hemicellulose and lignin are in it.
- Hemicellulose : semi-cristalline, so disrupt the ordonnance of the cellulose fibers and therfore affect the cellulose by lowering his propertie (in general), or increasing it by obtaining more felxible structure, that make sens since it became less cristalline. BUT, flexibility is not the only properties of wood's fiber.
- Lignin : considered by pulp & paper specialists and chemists as the glue between fibers. It alter a lot the structurale properties and the behaviour under chemical and mechanical treaments. Soft temperature treament allows to increase the flexibility of the fiber for a moment, so it is done when planking the hull. This is why mechanical treatment are done under 70-90 Celsius. Above 105 Celsius, the lignin begin to flow over the wood inherent structure and lead to the manufacturing of composite woodden structure as one example. Cheap wood material for construction are also made like this and recognized by the clear presence of chip in the board which tend to be brown.
Thanks for your comments. We both more and less agree on the most. I did not want to do it to chemicals.
for your info, the company "Novozymes" are -not them, but their clients -thousand of ton making fuel alcohol of any vegetable waste. They have made factories in US and Brazil to produce the necessary enzymes needed, to transform the Cekkulose, Hemi-Cellulose and lignin-lignin is washed with strong Acids to break it down so that the enzymes can take over.
further up -page 5 -i have added the chemical structure
Yeah, I know them. I worked on oxidizes nanocellulose on PHd project to allows antibodies attachment for bacterial detection. Kruger are able to produce industrial nanocellulose and I think they use acidic condition to obtained it. FInally, the project deviated to podiatric treatment putting a protein that I can not speak about here in fiber matrix for antibiotical or antifungical bandage. This work has been done by my master degree's partner.
Are you in the pulp and paper field El Capi or chemical industries ? I was resercher chemist and teacher in this field, particularly in recycling and flottation process, environnmental process and wet end chemistry. Now I am retired.

I haven't had much luck with those types of plank benders. They seem to burn out too quickly.
Dear Michel, Yes - although retired now for 10 Years I have been working for words biggest enzyme producer "Novozymes Denmark" I have made trials with Pulp& paper in Portugal, but I mostly used enzymes in the Brewing and Alcohol Industries and Fruit Juices. We had a special Enzyme, which can destroy the Alfa 1: 6 links, and thereby get s amylose, for a much better fermentation
I was born in Nothern Denmark -- Hirtshals -where there where a shipbuilding plant - the Danish Kutters, and saw how they bend the planks in a steam box. Do to wood in General and Planks especially -depending on a lit of which wood -has a lot of tiny holes. A god nest for Bacterial grows if the temperature is below 100º- the bacterias with Spores - lower temperatures is much worse. will come back as I have just got my old computer back, where I have quit a lot of images- maybe over the private line. el capi
We live in really a small world. Thanks for your presentation. May be a last point of interest : my principal work in recycling was in the developpement of and industrial technological transfer from mines to paper industries in the flottaion of ink instead of mineral. I was part of a consortiumwhich included an european compagny near you as Kvaerner, Norway.
I stop here, I do not want to hijack the thread. But there is a great community here.

Mortising chisels. Requires a mortising machine or adapters for a drill press.

I come from the mining industry. I am very familiar with differential froth flotation of sulphide minerals. Did you ever work with James Finch out of McGill University?
Hi, no. I worked mainly with Cascades, Chemprox, Kvaerner, Kao Corp., Université of Québec at Trois-Rivières. I was an employee's of Cegep de Trois-Rivières and Centre spécialisé en pâtes et papiers. External contacts with others researchers were with the compagnies cited here and Paprican.
I forget to specified Cominco, from where came the original technologies. I alors wrote the only original french book in the field:

Recyclage et le désencrage des papiers et des cartons (Le) | CCDMD.
I should be a little bit outdated now. It is cool to Know you better.

That is a big field. Deinking of paper and cardboard. I wish I was still at school when this started becoming popular. As you know, the mines are few and far between now and it would have been interesting to used froth flotation for something for the environnement.
Sorry I don"t mean to go off topic. I stop here

If you don"t mind me asking, where did you get that iron? I have been looking for that exact type for a long time. The ones I had from modelshipways don"t last more than 1 year.
It’s an old aeropiccola brand bender that is no longer produced, you can find them on eBay every once in a while. They do work well, and when it burns out you can adapt the head to a soldering iron tip - that’s what I did anyway… https://www.ebay.com/itm/393905802071?hash=item5bb69d8b57:g:1~0AAOSwY89h9kEK
This one is a good deal, I’ve seen them go for a lot more! Better hurry!

Thanks. I'll look to see if I can order it.
