Custom Router Bit for landing net construction

Over the years I have read and heard about so many frankly scary methods of cutting the groove in the frame of the landing net, that I decided to share with other net builders the same style of custom router bit that I use.   Originally I had the wing cutters custom made by a local firm serving the furniture industry here in Grand Rapids.  When I tried to re-ordered the firm had been sold to a large national firm and they were no longer interested in this small volume work. Luckily I have a fishing friend in the auto supply industry and I was able to find a Korean manufacturer who was able to supply a wing cutter of similar quality. Both the HSS and Carbide wing cutters are made in Korea. The arbor is made in the USA.  The ball bearings are made in China.   This router bit consists of a custom wing slot cutter about 1.075 inches in diameter and two 7/8 inch ball bearings on an extended router arbor.  It cuts a groove that is approximately 80/1000 of an inch wide and 100/1000 (1/10th)
