## Description

Woodhaven 8660 Jig for SOSS 100 Hinge Installation

## Features

- 8660 is for a SOSS 100 hinge - 3/8" wide x 1" long shallow mortise. Requires a 3/8" solid carbide upcut spiral bit (15406 or equivalent, sold separately) and a 5/8" Bushing & Locknut (5030 or equivalent, sold separately) to cut the mortises.
- 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.
- Requires a 5/8" OD bushing (our PN 5030K) and a 3/8" spiral upcut bit (our PN 15406), both sold separately. If using your own bushing, make sure the nose isn’t over 3/8" long.
- Lifetime guarantee against defects in material or workmanship. Made in the USA!

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    it's not this jig....it's the hardware
  

*by P***I on Reviewed in the United States on October 14, 2011*

This soss hinge routing jig is excellent.....I machined 4 perfect sized mortises, eachchecked with a digital depth gauge, and verified snug fit to perimeter of hinge body.The average depth varied no more than .005 and the body width was dead on, as well as thetotal length and the radius at each end, for a nice snug fit.Where I found a problem, was that with assembled fold down solid maple fronts...(two hinges each)...is that the gap between the edge of the closed front and the face frame they were hinged fromwas not consistent. One side of a given door might be .055 - .060 (1/16"),while the other sideor where the other hinge was might be as small as .010 - .015 (1/64"). I had purchased aquantity of these soss #101 hinges, so started exchanging them for the small opening gap,and found that it was the hinges that varied the gap when installed in the same mortise.In the end, to finish my project I had to shim the upper part of the hinge mortise,where thescrews mount the hinge,(sometimes just in the frame,and other times both the frame and door panel)with .005,.010, or .020 self-adhesive UHMW (Ultra High Molecular Weight).This stuff is priceless for shimming everything from tools andjigs to hinges that don't quite live up to the task.I HIGHLY recommend these fixtures from woodhaven. You just may have to figure more time for shimmingthe hinge discrepancy itself.

    Could really use a center mark!
  

*by A***K on Reviewed in the United States on February 22, 2015*

This jig worked great.  I've built similar jigs in my shop but for the degree of precision required for Soss hinges I figured this would be a worthwhile investment.  It definitely was a good call.  I was able to install 2 hinges in less than 15 minutes (including layout) with darn near perfect results.I was however building a very simple jewelry box.  It would be nice if this jig had a center line mark or some other kind of reference.  I originally planned to scribe a line at the end of the hinge (since there is not center line in the jig) but even that proved problematic since top plate is cut away at the edges.  If I'm missing something I'd sure like to know as I plan to use this in more complicated setups.I'd buy this again in a heartbeat if it had some kind of reference marks. . . without them I'd still probably buy it but feel that its overpriced.

    Undersized slot
  

*by C***E on Reviewed in the United States on January 1, 2022*

The product claim to work with a 3/4" OD router bushing.My bushing is .752 OD.The slot is only .742 in width.-- Update -- I purchased their 20 dollar overpriced bushing to see if it fit. It does not.Just buy the cheaper soss jig and don't waste your time with this oneMaybe their bushing that is advertised as .75 OD is actually significantly undersized. But I don't see any possible way this would work unless the template had at least 1/16" of clearance. I received a defective or mislabeled jig.
