Cutting Curves
When cutting curves, simultaneously feed and turn the stock carefully so that the blade follows the layout line without being twisted. If a curve is so abrupt that it is necessary to repeatedly back up and cut a new kerf, use either a narrower blade or a blade with more set. A blade with more set can cut relatively tighter radii, though the cut is usually rougher than cuts produced by a blade with medium set.
Always make short cuts first, then proceed to the longer cuts. Relief cuts will also reduce the chance that the blade will be pinched or twisted. Relief cuts are made through the waste portion of the workpiece and are stopped at the layout line. As you cut along the layout line, waste wood is released from the workpiece, alleviating any pressure on the back of the blade. Relief cuts also make backing the workpiece out easier, if needed.
The table below lists blade widths and corre- sponding minimum radii each blade will cut:
Width |
| Radius |
1Ú8'' | 3Ú16'' | |
3Ú16'' | 5Ú16'' | |
1Ú4'' | 5Ú8'' | |
3Ú8'' | 11Ú2'' | |
1Ú2'' | 21Ú2'' | |
5Ú8'' | 4'' | |
3Ú4'' | 51Ú2'' | |

Resawing
Resawing is the process of cutting a board into two or more thinner boards. The maximum board width that can be resawn is limited by the maxi- mum cutting height of the bandsaw. Maximum cutting height for this bandsaw is 73Ú4''.
Use common sense when resawing. Attempting to resaw too wide or too dense of a board may put excessive strain on the blade and be danger- ous.
Blade selection is an important consideration when resawing. Generally, the wider the blade, the better. In most applications, a hook or skip tooth style will be sufficient. Also, since most resawn lumber will be planed smooth, you can choose blades with fewer teeth per inch (from 3 to 6). While blades with fewer teeth per inch pro- duce rougher cuts, these types of blades offer larger gullet capacities for clearing sawdust, less heat buildup, and yield more horsepower per tooth.
To resaw lumber:
1.The bandsaw must be adjusted correctly. See Blade Adjustment section.
2.The table must be square to the blade. See
Table Adjustment section.
3.Use the widest blade available. The blade must also be in good condition.
4.Use a fence to guide work.
5.Draw a reference line on the edge of the board.
6.Support ends of the board if necessary.
7.Feed work slowly and evenly.
