Planning the Cut
Frequently, the accurate cutting location for working a band saw is to facet the blade. However, you can operate it by standing to the right-hand side or the back of the saw if it places you in a better position to see and control the labor. Be aware that if the blade breaks and is thrown from the saw, it has a tendency to whip to the right-hand side as you face the band saw. Make sure you retain a well balanced stance. Think around your body position at the beginning point of the cut as well as at the finish point of the cut to avoid overreaching.
Before the saw is turned on, the upper guides have to be adjusted for the height of the wood being cut. A good rule is to set the guide around 1/4″ above the top edge of the inventory. Retain in mind that the upper and lower guides are not guards, but are guides. The function of these guides is to support the blade and to help it run true. They also retain the blade from drifting and deflecting during the cut.
Two things are basic to properly functioning guides: feed rate and the amount of pressure applied to the inventory as it is pushed into the cutting path of the blade. Both feed and pressure will depend on the kind and thickness of wood, and the magnitude of the blade and speed that it is traveling. If the feed stuff is too rapid, the saw blade will chatter and screech as the back of the blade is pushed against the ball-bearing blade support at the back of the guide. If the inventory is fed too slowly into the blade, it could cause burning. Pushing too hard with one hand or the other could cause the blade to be pushed sideways, resulting in wear on the side guide procedure. This could cause the blade to dull or break and will more than likely result in an uneven cut.
When the labor is so huge or heavy that it causes you to pay more attention to supporting it than cutting it, an extra hand or support procedure would be a good idea. Always let the machine build up to full speed before beginning.
Before you cut wood it will be significant to think around the path of the cut. Some slices will swing in such a way that they will not clear the main upper arm support. Without a plan, you might find yourself in a position where backing out of the cut might be necessary.
There are a few simple rules for backing out of cuts: It’s OK to back out of linear cuts but not OK to back out of curved cuts. When backing out of short, linear cuts, the blade remains unaffected in the cut path and the inventory has little chance of catching the back of the blade. But when trying to back out of a curved cut, the inventory can catch the back of the blade and pull it off the wheels. If you bargain that you want to spinal out of a curved cut, merely shut the machine off and usage a stick to stable the motionless blade while you eliminate the inventory. If your project requires that cuts be made from two sides, always create the shortest cuts first. This will create backing out easier. Whenever possible, it is better to cut through the waste rather than backing out.
Cutting privileged corners that are whichever radius-ed or rounded can finest be accomplished by re-cutting on whichever the drill press or the mortise machine. This is a particularly handy idea when you have close-fitting ranges or want a high degree of accuracy. When cutting outside radii it would be a good idea to create relief cuts to help retain the back of the blade from binding in the Cerf.
