README for the Kerfed Lining Cutter.

I got tired of paying way too much for the linings for my instruments. I was also frustrated by the lack of shapes and wood species that were available. I wanted to try inside kerfed as well as outside kerfed linings. AND it needed to be fast.

So, why not make one. I fully understand that many have gone before me in this pursuit. I saw a couple of great ideas on YouTube and decided to modernize them.

There are 8 files included in the folder for this project. They are .stl files for printing the kerfed lining jig.

The two finger files really need to be printed with supports. The rest of the parts can be printed on a flat surface. I use the “brim on the outside” feature on the Bambu slicer for better adhesion to the bed. 

In addition to these files I used a scrap of 3/4” plywood that was about 150mm X 400mm. The rail was secured with 2 - #8 by 3/4” screws. You will also need some drywall screws 1 1/4” and 1 5/8” (these are suggestions, just don’t let them protrude through the bottom of the plywood. I also used 2 - R6Z bearings. Amazon sells a 10 pack for under $10. I am pretty sure you can substitute a 3D printed thick 7/8” washer with a 3/8” diameter hole. I also used one #4 finishing nail.

The video goes into gory detail on how to construct the device.
