These bushings are a tremendous addition for anyone doing template work with a router. This bushing set is exceptionally versatile because in addition to a complete range of sizes, the 'throat' where the bit comes through the bushing is relatively short and fairly consistent from bushing to bushing. The short 'throat' means the ability to use thinner template materials than with a usual set of bushings.
The bushings fit my router base perfectly and was well worth the price. Price and quality of this item is very good.
it jams in between the fingers on the jig rather than sliding in and out easily with a very small amount of clearance. The irony here, is that the Shop Fox bushing is unusable in the very type of jig they were designed for. The outside diameter of the bushing is too wide by a very small amount, i.e. I bought these to use with my Porter Cable 5116 dovetail jig. I want to like these bushings, but I have to stick with the steel PC bushing.These bushings appear to be nicely machined, unfortunately they are out of tolerance and completely unusable. More to the point, the 5/8 Porter Cable bushing is an absolute industry standard. In the case of my jig, it uses a 5/8 bushing for half-blind dovetails. This Shop Fox kit is essentially a box full of Porter Cable style bushings.
It contains all the most used sizes of bushings and works well with the adaptor I purchased for my Bosch router base. This is a quality product with a nice storage case.
They should also work on any router jig for the same reason.Negatives:-- The bushings would look better if they were polished; in fact, I polished one just to see (click See Customer Images, above). Since the guide and ring were brass, no noticeable damage to the bit or router occurred.-- Molded plastic case offers excellent protection against damage. There's no extra storage area, but none should be needed.-- Each bushing is machined from one piece of brass -- fine tool markings from a metal lathe are visible.-- This set costs less than Porter Cable's or Milwaukee's steel bushings.-- Because these bushings protrude beyond the router base by only 1/4" or so, they work fine on Leigh dovetail jigs. Positives:-- Includes 8 bushings and two locknuts (for use on two routers concurrently) -- most template sets include [only] 7 bushings.-- Bushings and locknuts are all brass, so they are impervious to water/moisture -- should last a lifetime. On the other hand, if polished, they will probably tarnish. With a brass bushing, the bit will likely survive intact. -- If a rotating router bit (e.g., tapered dovetail bit), touches a bushing made of steel, sparks will fly, and the router bit will likely be ruined. E.g., once, near the end of a day of routing doors for hinges, my template's locking ring came loose, allowing the guide to touch the spinning bit and the locking ring to rub against the router-bit lock nut.
