finally I found some pic. of the struktures- do not go to much into chemical problems. only that the 3 huge bio. products make a 3-dimensional structure. I general said to the student that is like building a house. The Glucose is the single brick, which together with the help of concrete-hemicellulose are glued together. The lignins are Stell or very Strong pillars which avoid that with the 1Th storm everything crashed

Thank you for your good ideas El Capi. I like the bean can idea; I think that it needs to be fixed into a (wooden?) cradle to stop it from rolling about. My own recent thoughts have been based around using copper pipe from a diy store as the vessel/chamber in which the plank is heated or steamed. Again this would need to be held in a cradle and the end(s) stopped-off with a cork perhaps?
May the vaccx be with you.

It is cheap and it works. I got the idea from a German Frind Axel Kullich -he has made the Pic. When I was building I nailed into a piece of wood, for holding it, and then a list of each side. but to, not to destroy your table. We need over 200ºC to destroy some of the bonds in this Macro molecule. Mechanical force can do it too, but not good for us
happy building and stay safe
el Capp.s the pic below are from 1976 with my wife and 2 years daughter. on top of the bookselves the are a model of the 1Th Norden from Billing boat and the other one is Cutty Sark

I've progressed to using this 25w Ademco dry mounting iron for my Artesania Latina dhow build. This tool was quite common back in the days of film photography when mounting a photographic print onto a card mount; used in conjunction with mounting tissue (glue). On my boat build this iron works very easily with 1.5mm basswood once I've dampened the wood with a small modelling paintbrush.

i HAVE OVER THE LAST yEAR STUDINGED THE PLANK BENDING. i HAVE 25 DIFFERENT CHAPTERS MOST OF THEM WITH SUB CHAPTERS. (sorry)
Out of all these methods, only a few is really working. some can be even harmful as caustic soda (NaOH). Soaking in water for a long time is either NO GOOG. The wood will such up water and by then1000 or more Bacterias, which can destroy de wood, so it is easy to bend and set nails, etc in, BUT the wood will dry out again, which gives some physical strengths, which can change the bulkhead position. In the end -after even having seen hear special equipment for bending- the is to me ONLY STEAM -high temperature- Electrically bending as seen here, with high temperature and FINALLY BUT NOT THE LAST "DRY BENDING" Many of you may not know it, BUT it WORKS and it is a very cheap tool. will add some pic. but it consists of an empty TIN (from Beans etc) which is Strongly faster too a piece of Wood horizontal. Now you take 3-4 candlelight (those from Chenice Restaurant, lit it and 30 min. later the tin is BURNING hot. Now simply add your planks -2mm no problem- and the good thing are, that the planks will stay bend, so one can make a batch
Why some are better than others, you will need to know, what is the raw material of Wood. You may be surprised WOOD is build up of 3 huge SUGAR molecules -YES sugar =GLUCOSE the smallest stone. The 3 parts is Cellulose 40-60% -HehiCellulose 40-60% and about 5 10% Lignin. Each sort has a different amount of mainly of Cellulose and Hemi-celluslose. To destroy this HUGE tridimensional Biochemical complex WE NEED a very high temperature
Will definitely try the tin can and candle method.

I have been using the old hot soldering iron technique successfully. Just keep dipping the plank in water to heat it and make steam.

I used Steam with very results. This Hot electricity device was not me. The HOT DRY METHODE es to me absolutely the best I have tried -have more than 40 on my back in building. The good thing with the dry method is that they STAY CURVED after treatment. On the pic. you see a batch done without further treatment. Everybody should use what they find the BEST one. I was just trying to tell you something, new-All builders) From the same person, I have got info about HOW TO SQURE GUNPORT by drilling.

Your gunport method sounds interesting, looking forward to seeing that, I am about to cut the gunports out on my HMS Ontario build so this would be very timely for me.
I this moment I do not have the web address, but the conoNY ARE OVER Facebook doing a campaign with shall vidio
