## Description

## Features

- The 8668 is specifically for the SOSS 218 hinge - 1-1/8" wide x 4-5/8" long shallow mortise.
- Requires a 3/4" OD bushing "Woodhaven 5032K" and a 1/2" spiral upcut bit "Woodhaven 15410". If using your own bushing, make sure the nose isn’t over 3/8" long.
- Hinge setback is built-in according to the manufacturers specs.
- Jig clamps to the work (no nail holes) and, using your plunge router, both the long/shallow and short/deep mortises are cut without moving the jig or part. Has two retractable stops for the short/deep mortise.
- Lifetime guarantee against defects in material or workmanship. Made in the USA!

## Questions & Answers

**Q: Is the clamping mechanism for the wood builtin?**
A: No, the clamps are not included.

**Q: Can this be used for loose tenons in 3/4'' wood with 1/4'' tenons?**
A: Probably not. The smaller models may work, but there's no way to adjust the mortise location to the center of the stock edge.

**Q: Will this jig work on face frameless cabinets ?**
A: It depends on your exact cabinet setup, but I expect yes it should work.   If you are mounting the hinge between the sidewall of your cabinet (ie no face frame) and the side edge of you cabinet door the jig should work the same way it does when mounting to a face frame.   On a face frameless cabinet you clamp the jig to the surface that will be routed with the jig's fence pressed against the front edge of the cabinet sidewall.  In the end the front surface of the door will be flush to the front edge of the cabinet sidewall.   Hope that makes sense.

**Q: can u send to mexico please??**
A: It will cost $30.00 US funds to ship (1) #8661 to Mexico via USPS Priority mail.  Duties and taxes are not included.  I would suggest you buy the #15406 router bit and #5030K bushing and lock nut.  Shipping will be the same.  Please contact me at lynette@woodhaven.com Thank you, Lynette @Woodhaven
