So yesterday I made a quick redesign, beefing it up and changing a couple of things. I modified only the one jig, but you will need to make two, each to taper one side of the hammer, and will be a mirror image of each other. Not shown on the bottom is the runner that fits in the slot on your table saw. You should be able to see enough to get the idea. <o:p></o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><o:p> </o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; ">You will see that my jig is adjustable for both width of cut and angle of cut – don’ try to make jigs where these values are fixed . When you have got the angle and depth dialed in, you can walk the jig over to the drill press, drill a hole through the turntable into the cross slide, and then into but not through the base. Stick a balance rail pin into the hole, and you will have an index for a preset that you can go back to quickly for a particular make of hammer. This is important, because setting things up involves a lot of trial and error and time (if anybody knows a quick way to do this part of it, I’d like to know!)<o:p></o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><o:p> </o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; ">This jig can be used for both hung and unhung hammers.

The jig consists of three basic levels: the base, which has a routed slot where the second level, the cross slide sits and can be adjusted towards or away from the saw blade by the adjustment screw at the end with an allen wrench, A machine bolt is counter sunk up through the bass, and goes through the slot in the cross slide, and locked in place with a wing nut. On top of that sits the third level, what I call the turntable. That is held in place and adjusted in the same manner as the cross slide, except that the turntable pivots around its bolt, and adjusts the angle of the taper. </div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; "> </div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; "><br></div></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; "><img height="480" width="644" apple-width="yes" apple-height="yes" src="cid:A45216D2-6005-4B7E-9F32-223CB666F02D@kc.rr.com"></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; "><br></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; "><br></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; "><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; ">Here is the view from the side which faces the saw blade. I have used a half inch bolt recessed into the hold down. The hold down pivots around the bolt. The hold down arm is made of Delignit bridge stock. You will want to shape it where it contacts the hammers, so as to have adequate bearing surface no matter what the shape of the hammer is. Line the inside with some coarse sandpaper or roughen it sufficiently with a checkering file or such so that you have a stronger frictional contact. Ignore the wood blocks seen under the jig, I used them to prop up the jig on its side to photograph it, and the runner for the slot in the table saw table is not attached at the time of the photo. </div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; "> </div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; ">If you are concerned that such an arrangement will not hold the hammer down with enough pressure, know that I can bear down hard enough on the hammer head that I could pull on the shank and snap it I wanted to.
