Making a V-Block

If your not familiar with a V-block, it is essentially what is says.  A block of wood with a "V" cut into it.  For our purposes the block is a 2 x 4 approximately 30" long or more.  The "V" is cut the length of the 2 x 4.  When working with cylinders, whether cutting or drilling, a V-block is very helpful in holding the work in place.
The first step is setting the saw blade at a 45 degree angle.  From here the blade depth needs to be set at 1" deep.  This should leave 1/2" of block remaining. measure1.jpg (25289 bytes)
Mark the center of the 2 x 4 and set the rip fence so the top of the blade cut is equal to the center of the board. measure2.jpg (26425 bytes)
This is what your first cut should look like. cut1.jpg (27685 bytes)
For the second cut you turn the board around and cut from the other end.  This pictures shows a sample cut confirming that the two cuts come together in the center of the board and complete the "V". cut2.jpg (27469 bytes)
Note:  It is important that when you make this last cut you do NOT stand directly behind the saw blade. (which you should not do any way).  Also be aware that there isn't anyone else behind you while cutting.  It is not uncommon when cutting rabbets or other cuts similar to this for the remaining piece of wood to launch back towards you like a javelin.
