When designing a stitch and glue hull for plywood composite construction and all developable panels, how can one predict how the plywood will bend?
Modeling designs in Rhino is one thing but I have no idea whether the wood will conform to the developable shapes I am modeling.
Location: auckland nz bending ply Here's a jpeg of the bow sections of the CBSkimmer - in 4mm meranti plywood. Bending ply requires some patience and slowly increasing clamp pressures, plus a few judicious saw cuts in a couple of high tensioned areas (but watch out the whole thing doesn't explode like a spiked balloon). Location: maine To calculate how far a panel will bend, rip a strip of it and bend. I've done coamings without steaming by laying them between two supports for a couple of weeks in the summer with weight bowing them down. Location: Utah Can anyone offer any insight into the phenomenon I described in my last post? I would also be interested to know if there is a commonly used term for this phenomenon, which would allow me to search on it to find more info. If you take a cut across a simply curved surface in any direction other than perpendicular to the curvature plane, you will be cutting across some portion of the original curvature. For prediction, I would imagine the amount is directly related to the angular difference between the section cut and the conic (if present) radial line or surface 0 isobend (don't know the term - 'contour' where bending = 0 ) factored by the amount of curvature or bending (perpendicular to the surface) that the panel has at that averaged (if twist) curvature location.
The situation you are describing sounds to me like the conical development you will get anytime you induce twist into a rolled sheet.
I use several surface development software packages to design hulls, and I normally export the design data into Autocad to finish the drawing.
I normally draw a fair chine in elevation and plan and then adjust the keel profile to suit, while adjusting the origin points of the conic projection lines.
If I haver had to alter the lines in Autocad, I then go back to Prosurf or Rhino and change the lines accordingly so I check the hydrostatics. What I have found is that performing a conic projection produces a possible conic solution to how the plates will sit, but it is not always the solution that the plates will find. There may be (certainly are in fact) much smarter people out there who know things that I don't about developing accurate cross sections. When making potentially dangerous or financial decisions, always employ and consult appropriate professionals.
However, after slaving away for countless hours and using any spare time that I had on my project, I realized that it was not coming together as easily as I had thought. I went out and purchased some more wooden boat plans, not really knowing exactly what I wanted to build.
After spending thousands of dollars on my childhood dream hobby, I was on the verge of just giving it all up. Just when I was about to give it all up, through sheer luck, I was fortunate enough to be introduced to a local, master boat builder.
Eventually, my skills improved, and I could proudly say that I had completed my first wooden boat. And what I discovered was this: Building boats is not hard if you have a step-by-step approach to follow. 31 years later, I'm still building boats.Over the years, I've amassed over 500 of my own boat plans! In order to help out some of my friends that also participate in this great past-time, I decided to go above and beyond and include simple, easy-to-follow, step by step instructions with all of my boat plans. That is because I decided to compile them into a collection and offer them to all boat builders so you can benefit from my 31 years of experience and feel like you have a master boat builder guiding you through each and every boat project. Over 518 detailed boat plans, schematics, cutting patterns, material lists for ALL types of boats. Everybody has the dream: Build a boat in the backyard and sail off to join the happy campers off Pogo Pogo, right?

You'll receive simple, easy-to-follow plans that will allow anyone from any walk of life to build their very own boat, and for a fraction of the cost of buying one. We have several groups of high school and college students working on MyBoatPlans right now. What's more, with an eye to economy and ease, I have modernized the boatbuilding process just enough to allow even the unskilled (and underfunded) to succeed. All of the boat plans are very detailed and easy-to-understand so even someone with zero experience can start building a boat today!
There are over 518 plans for different styles and shapes of boats so you have a huge selection on the type of boat you'd like to build.
My boat plans are designed to get the job done quickly, inexpensively and with professional results every time.
Detailed diagrams, specifications, and tons of photos to make the plans completely "idiot proof" so you don't waste time or money on materials you don't need. You get instant access to all the boat plans, construction details and building guides in a members page.
I am also offering you this package(all 518 boat plans, books and bonuses) on DVDs and books.
Avoid costly mistakes and extra charges and build with these carefully detailed plans and specifications. The good news is, it doesn't matter what boat you want to build, whether you're an experienced builder or if you're just getting into it, MyBoatPlans will cover it. This is an invaluable resource for anyone interested in boat building and this is included in MyBoatPlans.

Other plys will bend even further, like Hoop pine and of course the expensive aircraft plies in 1.5 and 3mm guages.
Any sheet material with conform to what is called a developable surface, whic is essentially a section of either a cylinder or a cone (or combinations of cylinders and cones). My father would take me out to harbor, and I'd watch the boats bringing in the "catch of the day". I got a good job and made a wage that was more than adequate to cover my family's expenses and even put some back.
The plans I had purchased were incredibly difficult to understand and left a lot to be desired. He held my hand over the next year and would help me "fill in the gaps" on the boat plans I had purchased. Without that man's knowledge, I never would have succeeded on my own by solely using the low quality, expensive boat plans that are commonly available. I’ve been told by numerous people that the guide was able to take even the most difficult carpentry construction methods and distill it down to simple and easy steps that even complete beginners can easily follow.
With minimal supplies, and a very small cost, you'll get your boat on the water in no time! MyBoatPlans is a big, comprehensive package that contains all the plans, measurements, and directions needed to build beautiful boats for oar, sail, or motor.

When you bend a sheet of ply, alloy or steel around the chines and centreline of most boat shapes, you will induce some twist into the sheet.
On a trip back home after the death of my father, I was going through some of his old things and found that first boat we'd built together. I spent far too much on materials as the plans just weren't clear and once again I ended up with a half-finished boat. My "hobby" was stressing me out and I still did not have a completed boat to show for the time and money I had invested.
Assuming you aren't independently wealthy, if you want a boat that's really you, you gotta build it yourself. There is a list of resources and support to help you with your project all the way until it is completed. It covers construction techniques and narrated instructions to guide you in your building process. If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable.

Most of the twist is where the chines lead up toward the bow, which is why you notice the effect most there. The process of performing a conic development looks scary to a novice but gets earsier with practise. My father was quite the handyman and was always working on something around the house, but these wooden boat plans looked much different than any I had seen in the past.
Autocad makes it much simpler, as the origin points of the cones can be dragged around to find the best origin points. If you look at the frame sections superimposed on each other, as they are in the sections plan, then you will notice that the aft sections are more likely to be parallel and the front ones tend to fan apart. Because of our financial circumstances, my father and I were never able to construct anything larger than a simple model, but my passion for boats only grew.
