This is so stolen from Geoffrey Noden of the AdjustABench. He demo’ed this at the Wood Show and Karson blogged about it. I thought it was pretty cool, and since it is not on the market yet, I thought I would make my own.
Not sure what I was doing, I made what looks like a paper cutter. The arm rides between two longer sides to keep it stable and square. It is about two feet long. The cutter bar is hinged with a bolt so that it is level when it is 3/4 of an inch above the base. This lets the cutter strike while it is level. Thinking that I wanted it strong and adaptable, I used bolts for the cutter mechanism so I could adjust it for tightness.
I made custom cutters buy sawing apart small blocks with S-curves and gluing them back together with double edged razor blades between them. These blocks are 3 inches long and 2 inches tall. The blades are 1.5 inches tall. I cut mine on the bandsaw. A scrollsaw would be a better choice but I had trouble cutting these with mine. I just went with what worked. I let the blade extend about 1/8 inch from the block. A note to be careful cleaning up glue squeeze out.
Then I mounted these blocks on the end of the cutter arm.
I chose 3/4 inch for the width of the inlay because I had a router bit and some stock that wide. I did the stock prep and started crosscutting strips to use. I started at 1/8 inch, reduced it to 3/32 inch, and ended up cutting 1/16 inch strips. This takes a very sharp blade. I used a high tooth blade without much set.
I added a stop block clamp so I could do repetitive width cuts if I want to. I used a poplar block with a dado to keep the strip steady and supply a soft landing pad for the blade.
Here you can see some of the strips that I will keep for a rainy day, and some test cuts.
Here I tried some repetitive cuts in some cherry.
