20 Adorable DIY Wooden Christmas Decorations

By David Moss April 22, The design layout involved for this project might just be the most difficult part of the whole process. Your first boatbuilding project should be simple and inexpensive, yet the boat needs to be useful when it is finished. The balance between these criteria is an individual decision.

The Internet is a great place to start when looking for a design. In my case I chose the "Dug", designed by Hannu Vartiala. I chose the Dug because I wanted something simple and inexpensive as my first boatbuilding project.

I modified the design to use 3mm plywood rather than 6mm. Do it yourself wood ornaments english only was the thinner ply cheaper, but it was much lighter.

It also gave me the opportunity to experiment with fitting gunwales. The finished product was a one person canoe. I do it yourself wood ornaments english pick up and carry this boat easily by myself and it practically floats on wet grass. It is perfect for fishing in the shallow rivers around the headwaters of the Murray Darling system in Queensland, Australia. The Dug was my choice, though. Your own choice of design for your first boatbuilding project may well be different.

Plywood is a man made construction material. The outermost layers are termed the faces. Since these are the only Best Wood For Turning Christmas Ornaments English visible layers, the appearance of each face youreslf subject to standard specification. In Australia each face of a plywood sheet is described by a code letter:.

In the USA some manufacturers use a letter code for the "front" face and a corresponding number for the "back" face, i. Typical applications using this grading standard are AA for marine plywood, Onaments for a wall cladding where only the front face of the plywood is visible, CD for structural plywood flooring and DD for structural bracing.

The adhesive used to bond together the laminations in the ply is of paramount importance to boatbuilders. There are four standard glue ratings:. Plywood for boatbuilding is traditionally purchased in 8 foot x yourse,f foot sheets. In metric this rounds out to mm x mm. It is apparent from these dimensions that it is necessary to join plywood sheets together to build even the simplest of boats.

It is do it yourself wood ornaments english manufactured to the same engineering standards as marine ply but is often quite suitable for a first boatbuilding project. The glues used between the layers are the same as those used in marine ply so delamination should not be a problem. Exterior grade ply may have one "good" face and the do it yourself wood ornaments english of lesser grade, for example AB.

The "Dug", my first boat, was constructed using exterior grade ply in pacific maple. Marine ply is an engineering product that must comply with published standards. These standards detail practically every aspect of the composition and performance of marine ply. If you are going to build a seaworthy boat, or a boat that must do it yourself wood ornaments english survey standards, use of a certified marine ply is essential.

If it is not stamped then it is likely to be material which has not passed final inspection. The butt joint is by far the easiest to make. It is formed by applying liquid epoxy to the edges of the sheets to be joined, pushing them together and gluing a strip of ply to one or both sides ebglish the seam. A variation is to use fibreglass tape instead of the strip of ply. Once the epoxy has cured the join is stronger than the plywood sheets themselves and the wood will fail under stress before the epoxy of the joint.

Hint : Epoxy does not stick to polyethylene. Laying down a sheet of polyethylene film, such as a disposable painters drop sheet, can save the embarrassment of gluing your work to the floor when joining sheets. You can also use baking paper for this purpose if polyethylene is not available. Lofting prnaments the process of taking the dimensions from a plan and drawing full size components on the construction materials.

Sometimes the designer provides the necessary measurements in the form of a table, but sometimes it is necessary to take the measurements directly from the drawing and scale them up to life size. Station lines may be drawn every 10cm for example. The distances either side of the centre line at each station line are determined from the plans and marked on the ply as reference marks.

Finally smooth lofting lines are drawn through the reference marks. A straight edge such as a steel ruler may be used for straight lines and the lofting batten is used for smooth curves. It is helpful to temporarily drive panel pins into eng,ish of the reference marks to ensure the lofting iy follows the correct curve. Once the lofting process is complete the lofting lines are used as cutting guides when the components are cut from wod sheet.

Epoxy is the material that makes wooden boatbuilding possible for the average person. It is used as an adhesive, a structural component, and to seal the wood to stop it absorbing water.

A thin layer of liquid epoxy is applied to the wood like paint. Some of the epoxy is absorbed into the grain and the pore structure of the wood while the epoxy is a liquid and when it hardens the wood is effectively eng,ish by a moisture proof barrier. The WEST System is a generic boatbuilding technique, but also a registered trade name for a brand of epoxy products manufactured under license from Gougeon Brothers, Inc.

Since that time epoxy systems, including the WEST System brand, have undergone significant development. Today there is a wide range of manufacturers offering epoxy systems for wooden boatbuilding.

A web search using the term boat building epoxy will return thousands of references, tailoring the search for your own location should return more than do it yourself wood ornaments english local epoxy manufacturers to choose from.

A word of warning however. Not all epoxy formulations are suitable for sealing a wooden boat against moisture. Marine coating epoxies generally do not include organic solvents or thinners. They may be described as high solids epoxies. Do it yourself wood ornaments english reason is that organic molecules are much larger than water molecules. When organic solvents evaporate from the liquid epoxy during curing the Do It Yourself Wood Ornaments Quotes departing molecules may leave microscopic tunnels that allow much smaller water molecules to enter.

This reduces their effectiveness as a moisture barrier and makes entlish unsuitable for use as a marine coating. When building my first do it yourself wood ornaments english boat I chose Bote Cotea high solids epoxy produced ornsments a company in Brisbane, the closest major city to my woor.

My choice was mostly influenced by convenience, ehglish for quality, and the desire to support a local business. Your choice of an epoxy system may be influenced by similar considerations but so long as you choose a high quality epoxy suitable as a marine coating, the choice is yours. The most do it yourself wood ornaments english part of the epoxy process is mixing the correct amount of hardener with the epoxy resin.

Stored separately the hardener and the resin will stay in liquid form. When mixed together the hardener acts as a catalyst and induces the resin to polymerise, or form cross linkages between its molecules.

As these bonds do it yourself wood ornaments english the molecules form the viscosity of the mixture increases and eventually, after a few hours, it solidifies. The reaction continues for several days afterward so it is important not to apply excessive stress to the material for at least 24 hours after application. The rate at which the polymer bonds form is dependent on the chemical properties of the hardener used and wopd ambient temperature.

The reaction that forms the bonds is exothermic which means heat is generated each time a new bond is formed. The hotter it is, the faster the bonds form and the hotter it gets, so new bonds form even faster.

The heat usually escapes to the surrounding air by conduction so it is important to spread the epoxy out in a tray rather than keep it in a pot after mixing. The greater surface area of the tray allows more heat to escape and increases the pot lifethe time when the mixture is still thin enough to apply effectively. The pot life of a batch of epoxy is generally about 45 minutes. Once a batch ro reached the end do it yourself wood ornaments english its pot life it is no longer possible to apply it, so it must be discarded.

It makes sense to mix up small quantities of epoxy at a time. Only mix up as much as you can comfortably apply during the pot life or you will waste a lot of expensive epoxy. Polyethylene containers such as those used by some do it yourself wood ornaments english food outlets are excellent mixing pots for epoxy. Epoxy will not stick to polyethylene so it is easy to peel out the thin layer of hardened epoxy next day and re-use the container.

It is important to follow the manufacturers directions about mixing ratios exactly. Adding more or less hardener to the mixture will not affect curing time or pot life, but it will reduce the strength of the bond. It is also important to use the type of hardener the manufacturer recommends for the ambient temperature of your workshop. Bote Cote recommend the following hardeners for use with their epoxy system:.

Metric conversion hint : go to google. This neat trick works in converting many other units too. Some manufacturers also supply a hardener accelerator. The accelerator is not a replacement for hardener, it just speeds the process.

This can be useful when you have a supply of tropical type hardener but want to use it with epoxy on a cold day in winter. Whatever epoxy system you choose it is important to follow the manufacturers englisb exactly when mixing.

In my case youreslf mix ratio was two parts of epoxy resin to one part hardener. While it is possible to mix epoxy to the correct ratio using measuring cups, or do it yourself wood ornaments english weight, I decided to purchase measuring pumps when I bought my epoxy.

Two hand operated pumps were required, one for the epoxy resin and one for the hardener. Mixing was simply one squirt of hardener to every two squirts of epoxy resin. I highly recommend measuring pumps to anyone intending to build a wooden boat. Once the epoxy and hardener has been dispensed in the correct ratio it is essential to make sure it is thoroughly mixed.
