>I have the Adjustable through dovetail add on template for current owners of an Omnijig 16 that I'd be willing to part with.
From the Manufacturer :
Use this template with the 5116 Omnijig to produce strong, professional looking dovetail joints. This template allows the cutting of through dovetail joints which appear more like hand-cut joints. The adjustability of this template allows varying the width of the dovetails for a unique appearance. Constructed of aluminum, this template guides the router to machine pins and tails for through dovetails. Requires 5/8-inch template guide and 3/4-inch dovetail bit with 14-degree angle and 5/16-inch straight cutting bit for 3/4-inch material--sold separately. Requires 5/8-inch template guide and 1/2-inch dovetail bit with 14-degree angle and 9/16-inch straight cutting bit for 1/2-inch material (sold separately). The template comes included with four spacer washers.
Amazon currently is listing this for $112. They frequently have sales of 20% off, so I'm thinking $90 would be a great price for a new one.
This one is new, has never been used, and I'll let it be yours for $75, which includes shipping via USPS Priority Mail in the US.
