Using a Horizontal Bandsaw
A horizontal band saw is a saw that has a cylindrical blade and two parallel armatures (firmer side). The armature is connected to the blade via cables. The machine operates at an angle (typically 45 degrees), whereby the armature moves in sync with the blade, cutting different sections of wood or other material in different directions. This cutting action makes it ideal for various woodworking tasks including carpentering, architectural carving, woodturning, finishing, and sawing.
The machine is powered by a cord that is attached to the saw’s drive mechanism. Before you get started, there are some basic steps that you need to be aware of: In this article, we’ll discuss a few of those basic steps, as well as a basic theory on how the law works. Make sure you understand these so you can get started quickly and efficiently. Keep reading for more details on using a horizontal bandsaw:
Some folks make the mistake of thinking that they can simply start and stop the saw from a power point, by unplugging the saw. When you do this, the motor stops turning – not exactly a great idea! It’s best to start the saw by turning the armature by hand, adjusting the speed to something a little higher than its normal setting. Once you’ve got it set up the way you want, you can start to operate the saw by just turning the handle.
With the saw installed, turn the armature by hand until the saw begins to move (usually, you will feel a clicking sound when it reaches its top speed). Once the armature starts to turn, it will move toward the blade. Now, adjust the speed to whatever you prefer. Keep adjusting the speed until the saw cuts at least the piece of wood or material you want to cut. This is where a skilled machine operator and good judgment come in.
The finishing process with a horizontal bandsaw is probably the most gratifying of all woodworking projects. Starting with the cutters, pull them apart and clean them, making sure to use a shop-vac to remove any dust that may be trapped in the cutters. Try to maintain a consistent cutting speed when you do this so you can cut through the wood quickly and precisely.
To complete the job, you should have one (or more) of the saw’s blade components removed. The blade that the saw runs on should be completely removed from the saw’s top and bottom, but not the cross-cutting angle. The saw must be capable of performing at least 100 degree cuts. After the blade is removed, the saw is ready to use as a regular table saw. Now, if you are wanting to complete the task of finishing, follow these steps:
For most tablesaws, you can use a regular flat bevel and rip fence along with the bandsaw. However, for that edge beveling effect, you’ll probably want to replace the fence with an angle bevel. It’s worth the extra investment to get the right height fence, which will give you better control over the angle of the blade, as well as a smoother finish.
Every machine shop should own a piece of band saw that’s manufactured for cutting large areas of wood and/or metal in a short period of time. The primary benefit of a horizontal bandsaw is that it can cut a wide variety of materials with a quick and efficient style. The basic process for hand band sawing is similar to general table sawing. It’s also important to remember that a hand band saw has more power than a standard table saw, so it’s best to start with the saw in an outdoor woodworking area or workshop.
