    Prick punching aid

    I made this prick punching aid for a friend many years ago. Once made, I decided I needed one too. The body of the tool is a through-drilled cylinder with one quarter of its body accurately milled away.




    Insert the punch, made from hardened drill rod, into the hole, align the edges of the cutaway portion with your scribe lines and voila (not viola - that's a musical instrument), the punch mark is on the intersection of the lines.




    But wait, there's more! (He shouts, madly waving his Ginsu steak knife.) Ever had the problem of having to align to the edge of a piece of stock angled in the milling machine vise? Drop the body of the punch over the edge and use the edge finder to locate on its circumference. Since the diameter of the punch is known (or can be easily measured), it's a simple matter to locate the spindle axis directly over the edge.




    The one shown is massive enough to not move under the friction of the edge finder but, if you have problems, apply a dab of oil or grease to hold it in place with the capillary action. (I have a miniature version that requires this action to remain in place.)

    From the viewpoint of the average man, I can only say "Ouch!".

    I didn't mention it in the original post but an interesting feature of this tool is the fact that you can punch the intersection point of two lines even if the lines don't quite intersect. I'm not sure this interesting feature is a useful feature but there it is. :-)
