Nice build Dave. I also made one following William Ng’s video. Like Petey I also bought an Incra. Sometimes when it rains and the humidity is very high my wood expands and the sled jams in the miter slots.
I like how you used the aluminum miter bars, great idea. I bought my miter bars from HD. They are shipped to the store and much cheaper than most and I picked them up without paying freight. They also have a no freight policy for orders over $45.00. Which I’m sure your aware of.
