Timber Joints for Woodworking

Timber differs in structural characteristics. Any woodworker should have an understanding of timber to make sure that he can choose the right material for his projects. Timber is divided into three classes – structural material, shop and factory lumber and yard lumber. It is subdivided into common lumber and select lumber.

Common lumber is used for utility purposes and general construction. It is identified from different grade names.

  • 1 – Also known as watertight lumber, No. 1 is tight knotted and durable. It can be used without waste.
  • 2 – No. 2 common lumber is usually used for sheathing, framing and other structural forms where the strain or stress isn’t too much. Its general quality is similar to No. 1.
  • 3 – No. 3 common lumber is ideal for rough work like rough flooring, footing and guardrails. It allows some waste.
  • 4 – It has coarse features such as holes and decay. No. 4 is used for roof boards, sheathing and subfloors in cheaper construction. It is often used for crates and boxes.
  • 5 – No. 5 is used for crates, dunnage and boxes with low quality requirements. It’s not manufactured in some timber varieties.

Select lumber has an excellent finish and physical appearance.

  • Grade A – practically clear and ideal for natural finishes
  • Grade B – generally clear and perfect for natural finishes like Grade A
  • Grade C – ideal for high quality paint finish
  • Grade D – perfect for paint finishes between common grades and high-finishing grades

Sizes Available

Timber is usually sawn into average dimensions, providing uniformity in ordering materials and planning structures. Standards have been set for dimension differences regarding the quoted dimensions of timber and its average sizes when dressed. Quoted size indicates dimensions before surfacing. The common dimension difference is 2″ x 4″. It will be the nominal dimension, but the real dressed size is 1 ½” x 3 ½”. The exact size of dressed timber is less than the sawn dimensions due to finishing and drying.

Uses of Timber

Timber is used in frame construction. It used mainly for the walls and frame. For frames, it is used to support the finished parts of a structure such as the joists, beams and girders, posts, top plates, rafters, subfloors, knee braces and sole plates. Softwoods are also used for wood framing. No.2 common lumber is often used for framing. Girders, beams and other heavy frame parts are made by combining various components of the framing material.

The outside walls of a frame structure usually have three layers – the siding, sheathing and building paper. Grade No. 2 common softwood is typically used for the siding and sheathing. This grade has solid knots and doesn’t have spaces. Siding is either horizontally or vertically applied. There are various types of bevel and drop siding that can be applied horizontally.

What to Consider When Purchasing an HVAC System

Choosing an HVAC system for the home is a big decision and not one that consumers should take lightly. There are a few things they need to consider when making this decision so that they choose the best system for their needs.

First of all, homeowners need to make sure they are choosing a system that is the right size for their home. There are different types and sizes of HVAC systems, and one that is too big will use up a lot of energy unnecessarily or will simply cost far more than the homeowner needs to pay in order to keep their home at the right temperature. One that is too small will have to work extra hard to keep up with the temperature needs of the home.

Next, homeowners should consider the rebates that may be available to them. There are often energy saving rebates available from the government that come from buying certain types of environmentally friendly HVAC systems. Consumers need to be aware of these so that they can not only save money but also buy an HVAC system that protects the environment and doesn’t waste energy.

They should also take time to compare prices. They may be able to save money by choosing an HVAC system that is cheaper at one location than another. Not all companies will have the same price on HVAC systems, and homeowners can keep their purchase under budget by comparing prices and trying to get the best rates.

It is also a good idea to use a resource like HVAC in Myrtle Beach to get expert advice on which HVAC unit to choose. HVAC in Myrtle Beach can be expensive, but getting the right one can save homeowners money over the long run. They can enjoy efficient energy production and stable temperature levels with a system that is right for their home. They simply need to take their time to compare what’s out there and ensure they are getting the best deal possible.

Calling experts to find out what they think the homeowner should get is an excellent way to ensure the right choice. The homeowner doesn’t have to go with what the HVAC specialist recommends, but they can at least take their advice into consideration and use their expertise to inform their decision.
