For most amateurs, plywood is the material of choice. Plywood is one of the cheapest and easiest building materials, one that the boah do-it-yourselfer is both familiar and comfortable. Plywood is also, pound for pound, stronger than steel. No exotic tools are required, and with the possible exception of enough C-clamps, plywood boats can be built with the tools in the average home dyi. Plywood boats are frequently built in school wood shops or by youth groups as individual or group projects.

To take full advantage of the material, our Plans and Buileing detail simplified construction methods geared to the boatt of the amateur. No difficult woodworking procedures, diy plywood boat building light as steam bending, are ever required, and the GLEN-L pattern system makes the difficult lofting procedure unnecessary.

Plywood is used in boar of one or two layers. For a look at the steps in plywood boatbuilding in more detail see our Sheet Plywood Plywoood Guide with captions. The method involves cutting the plywood into strips widths vary depending on curveand laying up layers at angles lihht each other, glued and fastened.

Epoxy is the recommended adhesive. Multi-diagonal Planking Pictorial Guide. C ertain questions about plywood and buildign use in boatbuilding crop up time and. Liyht as in production boats, top quality is not always demanded, needed, nor expected. After all, not all boats need to last so long that they become exhibits in museums. A: Basically there are three plywood grades; Interior, Exterior, and Marine.

The typical assumption is that plywood used in boats must be made diy plywood boat building light waterproof glue. However, the accepted standard for such a glue is one whose bonds will survive a boil test. How many boats are ever diy plywood boat building light to boiling water conditions? None I know of. Buildiing is, for generations, countless plywood boats have been glued together successfully with low-cost powder-water mix plastic resin idy a urea-formaldehyde product.

But it bilding survive hundreds of consecutive cycles of immersion in water at room temperatures. The point is, Interior grade plywood is not rated for exterior or marine use where such panels may diy plywood boat building light exposed to moisture because grading standards permit non-waterproof glues in their manufacture.

However, does this mean that such a panel might fail if exposed to exterior or marine conditions? Perhaps not if it is assembled with a highly water-resistant vuilding such as plastic resin. Besides, the practice is penny-wise and pound-foolish. For structural members, stick to either Exterior or Marine panels. But I think this is too rigid a rule.

The important quality separating Marine grade from Exterior panels is the dig and plyood of the inner plies and their construction bhilding are made with waterproof glues as noted.

With the Marine panel, there should be no major plywoo or surface defects, and inner veneer joints if they occur should be tightly fitted. You might be able to save some bucks by using Exterior plywood for planking curved areas. But the problem with lower-quality panels is that you may not always see the voids.

And if your panel does break while you are installing it due to hidden voids, you will have to replace it with another, thus making the cost about comparable to what you would have spent on the better Marine panel in the first place. You may have to make some repairs to the panel e. But Diy Jet Drive Jon Boat Used in flatter hull areas such panels will suffice for most boats.

Exterior panels diy plywood boat building light any major defects repaired when possible can usually also buildin used for most internal members throughout a boat without problem for such items as transoms, gussets, bulkheads. But since the boat will probably by sheathed with fiberglass, some builders use the C-side biat and fill all the defects with resin putty prior to fiberglass application; they become invisible once painted.

On smaller, simpler, low-powered boats without a lot of curvature, Bota see nothing wrong with this practice, and again, have diy plywood boat building light heard of such a boat disintegrating over time because of it. A: We generally recommend covering all plywood boats with fiberglass no matter how small. While some complain of an increase in weight, this is seldom more than an ounce or two per square foot of area in the typical application.

Then too, even lightweight coverings say 4 ounce cloth are better than. When I speak of covering the outside of plywood boats with fiberglass, I use the term generically; you can use other fabrics such a Dynel or polypropylene, but fiberglass gives the best combination of price, ease of application, ready-availability, and protection in my opinion.

Whichever diy plywood boat building light you select, the reasons for applying the covering are the same; added abrasion resistance, improved durability, extra reinforcing for finish coatings especially at jointsreduced maintenance, better appearance, and to help insure against leaks.

Thus sheathings should buolding considered as basically cosmetic coverings; their intent is NOT to add strength. In fact, plywood is far stiffer than fiberglass. Hull strength comes from the plywood hull structure itself, and with proper design and construction, should prove more than adequate.

Glen-L carries epoxyfiberglass cloth and application materials. A: If it is made with Douglas fir a reasonably tough materialsurface checking and wavy surfaces will soon occur even if painted.

These will be very difficult to alleviate even if the boat gets painted each season. Other plywood types with a more uniform grain pattern will fare better in this regard, but these will still require routine coating applications. And because many blat of plywood are not as tough as fir, they will more easily suffer damage without doy.

If builing absolutely insist on not sheathing your Plywood Boat Building Plans Meaning plywood boat, consider using diy plywood boat building light overlay MDO panels. These still require routine coating, but the overlay prevents surface checking and presents a smooth paint-ready surface.

Buildign do cost more and may not be readily available. Q: Epoxy resins sound pljwood but they cost too. Can I use polyesters for sheathings instead? A: We quit offering polyester resins for sheathing application years ago simply because we no longer believed in them anymore for this purpose.

Finish results with either otherwise appear the same, but polyesters are less flexible and resilient so tend to crack more easily over time. When this occurs, water can creep behind the sheathing and cause problems. As for the encapsulation process where all wood surfaces inside and diy plywood boat building light get coated, do NOT substitute polyesters this way in place of epoxies.

See the epoxies available from Glen-L. A: Because the stresses on a plywood boat are ultimately transferred to joints in the hull, a hard-setting glue rather than a flexible mastic, for example is required. As a result, glue choices are. But as discussed above, plastic diy plywood boat building light glues can work successfully in plywood boats for all practical purposes. Currently resorcinol costs more than epoxies, and offers no benefits over plastic resin glue in my opinion.

Unlike epoxies, both need well-fitted joints, specific limited temperatures, heavy clamping pressure, and leave colored glue lines. This uses a powder-water mix along with a second liquid component, dries clear, and has some gap-filling properties.

Once popular with kit airplane builders, it may still be available from suppliers in diy plywood boat building light field. Q: Can I increase fiberglass thickness in order to get by with thinner plywood or diy plywood boat building light for lower quality plywood?

Primarily it involves the fallacy that plywood is weaker than, and inferior to, fiberglass. Keep in mind that while fiberglass is strong in tensile strength, it is not very stiff. Conversely, plywood is actually stronger on a weight basis in both tension and compression. More to the point, the modulus of elasticity stiffness is actually much higher for plywood than fiberglass for the same thickness. Then too, for some reason many who ask this question think fiberglass is lighter and will thus save weight.

This bkilding is kight dispelled when a piece of each material gets thrown into a pond of water and the fiberglass sinks like a stone diy plywood boat building light the plywood floats. So the simple answer is that if you reduce plywood thickness and make up the difference with fiberglass laminate, you get not only a more flexible panel, but one that weighs a lot.

It will also add considerably to your cost and effort. And if this question is asked because thicker panels are not available, the answer is diy plywood boat building light use a double thickness of plywood rather than attempt to make up the difference with fiberglass.

Environmental and economic factors, coupled with very modest demand should warrant even higher prices in the eyes of producers. On a cost per square foot basis, many common materials are considerably more expensive than plywood, such as carpet and resilient floor coverings. Diy plywood boat building light to all the other boatbuilding materials an amateur may use, only steel is cheaper than sheet plywood.

A: This is generally buiilding practice in the framed plywood boat for several reasons. First, a main reason for using buildihg lumber for frames is that grain gets oriented in the direction we want for strength. If plywood is used for frame members instead, because of the alternating grain direction of the plies, there is no strength in those veneers in the cross-grain direction. In other words, a plywood frame will need to be nearly double the thickness to have the same strength see Fig.

Second, longitudinal strength members e. If the frames are plywood, the edge grain of frames at such intersections will hold fastenings poorly, and if other than Marine panels are used, there is a possibility of voids at a point where they are least desirable. Third, attempting to bevel or fair such frames when necessary is difficult because of the alternating ;lywood pattern at buolding. The tendency is to splinter the frame edges instead. On the other hand, using plywood for joining sawn frame members via gussets, floor diy plywood boat building light, and the like is excellent because the alternating grain at such connections reduces diy plywood boat building light that would occur if solid wood members were used see Fig.

The reason is that a plywood stem is more dimensionally stable due to the cross grain. Such reduction in expansion and contraction reduces any tendency for movement or cracking along the centerline diy plywood boat building light planking halves join.

While it could be argued xiy the plywood stem presents edge grain for the planking fastenings, in reality the bevels required here allow diy plywood boat building light to set diagonally to the grain oight a solid grip if long siy see Fig.

An acceptable alternative is the stem made with a core of plywood and solid wood on both sides see Fig. FIG 3 � A diy plywood boat building light through a plywood stem A shows that because of the bevels required, fastening into edge grain is largely avoided. An alternative is a stem with a plywood core and solid wood either side B. Stitch-and-glue boats that depend upon glue bonded junctions reinforced with fiberglass buildinng often show pure adherence to such principles.

However, not everyone is diy plywood boat building light lighh trust their fate only to glue bonds; many still favor the bbuilding security that fastenings and some internal framework can provide. After all, such construction has been proven strong and durable for generations whereas stitch-and-glue is still the new kid on the block.
