« Part 16: A few hole clamps Part 17 of Shopmade Luthier Tools series Part 18: Violin bridge jigs »

This is a device that lifts the strings off of the bridge of a musical instrument so that the bridge can be removed during the fitting/adjustment process. I think i first saw one of these in a video on YouTube. After looking it up, I decided it was definitely something I could make. It’s basically a thick bridge, this one is for a 3/4 cello, which has a top piece which lifts with the assistance of a screw. The top piece runs on guides. The commercial products run in slides on the sides while homemade ones I’ve seen use a pair of dowels in the body of the tool.

Judging by the color of the grain, mine is made of poplar. I chose it because it was a convenient piece of 1/2 inch thick material. I added splines to the edges for strength because the grain runs short. I used brass pins and a #10 screw for the hardware. I threaded the wood directly instead of adding a nut somewhere. I stained it with Golden oak stain to cover up the green grain color.

Aha! I didn’t notice the notches on top until the last two images. Now, I see! This is fun to learn, Dave.
