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. Stitch and glue, and check out Stitch and glue on Wikipedia, Youtube, Google News, Google Books, and Twitter on Digplanet. Stitch and glue is a simple boat building method which uses plywood panels stitched together, usually with copper wire, and glued together with epoxy resin. The stitch and glue method was developed by woodwork teacher Ken Littledyke for the manufacture of canoes, later sold as the 'Kayel' in plan and kit form, using plywood panels joined by fiberglass tape and resin. The method was adopted, substituting copper wire ties rather than fishing line as in the early Littledyke examples, for the construction of the Mirror Dinghy in 1962. Although stitch and glue is similar to a traditional form of boatbuilding from northern Europe, particularly Lapland, called "sewn boats", it is not known if Littledyke's development of the stitch and glue methods was influenced by that technique.
In the United States stitch and glue boat building was popularized in the mid-1980s largely through Harold "Dynamite" Payson's articles in WoodenBoat magazine and books on building "instant boats" designed by Phil Bolger.[3] These boats were constructed of plywood with seams filleted with fiberglass tape and could be built by DIY amateurs of modest skill and relatively meagre resources. The technique consists of stitching together plywood panels with some sort of wire or other suitable device, such as cable ties or duct tape and staples. On the outside of the hull, the wire is snipped, removed (best practice), and the joints filled and sanded over.


An alternative is to use dabs of thickened epoxy in between the "stitching" to join the panels, and after it has cured, completely remove the wire stitches instead of just snipping them off on the outside. True stitch and glue designs generally have few bulkheads, relying instead on the geometry of the panels to provide shape, and forming a monocoque or semi-monocoque structure.
The "Instant Boats" developed by Phil Bolger use simplified framing and stitch-and-glue style plywood sheet joining and bulkhead gluing. The Dug, an 18-foot (5.4 m) long canoe that can be built entirely from one sheet of plywood.

Federal Reserve officials, worried about weak growth overseas, are endorsing new measures by foreign officialsa€”most notably at the European Central Banka€”to stimulate their economies. Bob Bonnen blurs the lines between work and play whether he's building kayaks in his garage or on the clock, playing music at tropical resorts. Inside a bright, remodeled 60,000-square-foot hardware store that they moved into in 2012, 137 people a€“ the bulk of them in manufacturing a€“ cut, stitch and glue together waders that are shipped to more than 450 specialty fly shops in the U.S.

With Instructables you can share what you make with the world, and tap into an ever-growing community of creative experts. After you've got your joint somewhat solidified with a weld of thickened epoxy, you can remove the cable ties. I'm looking to build this same boat this spring, and would prefer to avoid the stringers as you did. She has proven seaworthy so far, and I think that the fiberglass joint will prove to be stronger than a stringer joint in the long run.
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). This type of construction can eliminate much of the need for frames or ribs.[1] Plywood panels are cut to shape and stitched together to form an accurate hull shape without the need for forms or special tools.
The technique was then popularised by the first TV DIY expert, Barry Bucknell, in about 1964. The Mirror is so named because the design was sponsored by The Daily Mirror newspaper, a fact reflected by the historically red sails. All these methods of stitching or suturing the plywood panels of the hull are simple methods of clamping the hull parts together before they are permanently welded or fused by epoxy and fiberglass tape joints. The outside of the joint, or entire hull, may be fiberglassed and glued as well, providing additional strength. With the wires removed, a fillet of thickened epoxy is applied over the entire length of the join. But larger stitch and glue boats may have many athwart ship (sideways) or longitudinal (lengthwise) bulkheads in effect egg crating the interior with these members also fused into the final structure with the same type of glass tape and epoxy joints as the major hull seams.
While the use of relatively few plywood panels (which minimizes the joints and makes the construction easier and faster) limits the shapes possible, the simplicity and low cost of the stitch and glue technique makes it the method of choice among most amateur boatbuilders. Step-by-step building books about the boats and plans for many were sold by Harold Payson of Thomaston, Maine. Check out Devlin Designs - a boat boat builder that pioneered modern stitch and glue construction using plywood for an especially strong and efficient construction process. Note that in that respect are II steal design like a shot buttons for each set of plans one for UK We can ply you with all you require to build a diminished boat operating theater canoe from the DIY plywood canoe plans in the uk.


Because the stitch-and-glue joint is inherently waterproof, whereas stringers require caulking, the fiberglass joint will maintain a seal for longer as well. One built this gravy holder this time last year I have had so a good deal enjoyment out of her and i would the likes of to portion out the experience with. 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.
Once the epoxy sets solid in most cases the stitches or other clamping structures are removed leaving only the fused plywood panels behind.
The combination of fiberglass tape and epoxy glue results in a composite material providing an extremely strong joint, something close to 8-10 times the strength of fastenings and timber framing that might have been used in more conventional plywood construction. Simple software CAD packages are available for designing stitch and glue boats, and there are many Internet bulletin boards, newsgroups, and mailing lists dedicated to the subject of stitch and glue boats and various popular stitch and glue designs.
Some additional wood is often used, for supports, chines, or as a transom, though some can be built entirely with the sheet of plywood. I recently modified the Mini-Cup Sailboat plans, normally calling for assembly with wooden stringers, to stitch and glue.
Third year in the water, I modified the swing board to a fixed fin keel, moved the centre of resistance aft almost a foot and what a world of difference. If you go to an electrical supply store, or an aircraft parts store; they sell a tool made for tightening and cutting zip ties.
The advantage of plywood construction Indiana the skin applications programme of boat building is it's resistance to warpi. 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. As such, unlike other construction techniques of the day, which required specialist skills and tools, Stitch and Glue was supposed to put boat-building within the reach of the average public. Copper wire is popular because the wires can be twisted tighter or looser to precisely adjust fit, and because it is easy to sand after gluing, and it is suitable in a marine environment if left in place, but mild steel electric fencing wire can be used just as easily and then can be removed completely from the hull structure. They are not necessarily designed for light weight, but like the original Mirror Dinghy, for simple construction.

Autocad makes it much simpler, as the origin points of the cones can be dragged around to find the best origin points.
The plans predate CAD panel development software so the shapes are extremely simple in some cases.
When you've squeezed the trigger to the adjusted tightness it automatically cuts off the tail flush with the lock.
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. Once together, the joint is glued, usually with thickened epoxy and fiberglass on the inside of the hull. On your mini cup, modifying the centreboard is a no go, but getting the upper spar mor upright, moving the 2 mounting points forward or shortening the boom, would all move the CE forward.
