Coping saw jig

Everyone seems to be making Tims three-piece puzzle. Dattatreya Parupudi posted his a few days ago on the Mere Mortals Facebook page. Dattatreya doesnt have a bandsaw or scroll saw, so he cut it using a coping saw and chisels.

He then posed the question: "How can I cut straight lines using a coping saw?"

Well Tim Sluder actually has a coping saw jig! This is pretty cool. If you like, heres a PDF version.


Here are his instructions: 

The jig, works best when clamped in a vice or screwed to awork bench. Coping is a two-handed operation that iswhere this jig helps. You have to keep turning your workback and forth to get a straight line as you saw. Well, asclose as you can get due to the blade flex. Make sure to lubethe saw blades to aid in cutting and preventing brokenblades. This jig can be used with a jeweler saw or files.These jigs are easy to replace as they wear out. I used thistype of jig when I was in high school(1975), we used ajeweler’s saw to make jewelry out of coins. Try cutting outthe face on a dime. Let your imagination be your limit.Enjoy.

Finally, there was a question about a couple dimensions in Tims design. He has updated it. Here is the new plan.

Thanks guys!
