The Jig is Up!

From the crazy but intensely creative mind of pioneer builder Thomas Durr (Doc's Mandolins ), a new way to tap tune mandolin tops and internal bracing prior to assembly. Part genius engineering, part Frankenstein contraption, Tom is constantly inventing and tweaking new equipment and blatant "heretical" processes to approach his unique jazz mandolin designs. (We're selfishly partial to builders daring enough to create these, and if you haven't checked out our Builders Spotlight, spend a little time there!)

Check out his latest apparatus: Deflection Jig

A concept borrowed from builder John Garrity, Tom explains his creation: "I made it for carved mando tops. Basically it allows you to carve the top and tonebars to a point that the top has flexibility yet strength... Not magic, but puts you in the ballpark. Then you tap tune from there. Had to do some major 'adapting' with shims and such to test this different style of top construction. But it worked well."

In regards to bracing, Durr is exploring "offset X" in attempts to free up the bass, circular to support the forces of a floating bridge, as well as add central mass. We hope to offer a review of his unique designs soon.

Stay tuned...
