The new plans page SNX-L04 was started. This is the Tri-Gear main gear mount plans page. The welded part was provided by Sonex LTD. I found that a Gear Locator Tool/Jig, SNX-L04-10, was highly recommended. So, off to the local Home Depot to pick up need plywood and screws. The plywood was cut to shape on the table saw. Right angle brackets were used to hold the two pieces together.
