I made a dovetailed block on the Bridgeport. The block clamps onto the ways on my Taig microlathe and acts as a travel stop for the carriage/cross slide when I am using the dial indicator.
I bought an 8-flute 45 degree dovetail cutter from MSC, after a misfire with another cutter. The first cutter I bought specified the cutting width as 1/4". Much to my surprise, that was the tip to centerline distance, and it would only cut a dovetail 1/8" deep. Since I needed a 1/4" dovetail, I had to buy a 3/4" cutter.
Here is the part during machining. First I cut the U-gouge using a half-inch endmill, and then I made multiple edge passes with the dovetail cutter - each one at full Z depth but progressively further into the dovetail slot. @BobKarnaugh pointed out that the tiny tips of the cutter were likely fragile so I took a lot of very shallow passes - probably more conservatively than needed.
I subsequently ran an end mill along the inner top pointy edge of the dovetail to eliminate the sharp knife edge.
This is a simple part. I posted this here because it seemed to be an interesting curiosity while I was machining it - we don’t stock dovetail cutters so not too many people cut dovetails on the Bridgeport.
