It's a Bottom Cleaning Dado router bit, 1" diameter. Bought it on
Amazon, shipped from a company called PrecisionBits. Yonico is the bit brand name. Only $13.95 shipped.....
Setup is a basic drill press from Sears, I think it was $139 (I used points from a Sears Master Card to make purchase just for this project). Made jig using small scrap pieces of plywood and screwing the "L" shaped piece(s) onto the plywood base/table, and then attached the jig to the drill press's metal table using bolts and wing nuts that came with press. Getting the chips centered on the jig and setting the proper milling depth was the most difficult part of it for me (although someone more experienced than I could probably have done it faster and easier perhaps).
The milling itself isn't difficult, just time consuming and tedious.
It was worth it for me simply because shipping costs of sending chips to Gear in Canada and then return shipping was quite expensive for 800 chips. When I added in the cost of milling, it just made more sense for me to do it myself. Nothing against Gear at all, it was just the international shipping pricing was beyond our control and was a deal breaker for me. Gear was great to work with and his labels are awesome. I used both his 2 mil unlaminated labels (cash set) over existing Paulson inlays and his 7 mil (I think) laminated labels on my tournament set.....highly recommended.....they turned out great!!
