I have a craftsman router and there are 3 holes to mount the bottom plate to the base and there are 3 holes that are closer to the bit (smaller circumfrance).
For a bushing? of some sort any one know about that?

Hi mwm500

Some Craftsman routers come with a steel guides (templet guides(bushing) that are held place with a steel lock ring nut.
But the adapter must be held in place 1st. with 3 screws. :)
If you don't have a adapter you can get one from Sears or from HarborFreight that comes with a brass templet guides SET.
for 16.oo bucks with brass guides :)

BESURE to read the manual PDF file on the same web. page to make sure it will fit your Sears Router, they do list one but I don't know your model number.

Depending on the age of your router, Sears has always had a special unique guide bushing set, that you attached to the 3 small holes around the router bit center opening.

The steel guide bushing came in a set of 3, if I recall, and are the same guides used with their dovetail/boxjoint jig. See attached pic.

According to the owners manual for a Sears 315.17490 router,the template guide bushings is part #9 25079. See pics

I noticed on eBay two recent auctions for the above set of Sears guide bushings.

Needless to say, the Sears guide bushing are a pain to change as you have to unscrew the 3 screws to change guides and the guides are steel not brass which can cause damage to your bits if not perfectly centered, as I found out. They are also deeper in depth and designed for their dovetail jig or lettering guides and not versatile for use with 1/4" thick pattern templates. :( :(

Options, for using guide bushings would be to change bases either to a universal sub base such as Vermont America #23458 Router Guide Bushing Kit w Plate (also steel bushings)(see pic) or go with a Oak Park 7" x 7" sub base that accepts 1 1/2" brass guide bushings. Bushings are available from either Oak Park or Lee Valley depending on your preference.

Oak Park should have a sub base that fits your router as you can see from the following table. See pics

You will find that a 7" x 7" sub base is much more versatile to use and will give you better control and balance while routing and if you decide upgrade to the Oak Park table system the 1 1/2" bushings will be inter-changeable with the other plates available.

I hope this info helps you find either the correct bushing set or opens up your available options.

Craftsman routers have those holes for their bushings/guides.
Labric listed and has shown pics of your best option for sears routers. I got lucky and my Oak Park plate mounts to both my sears and my makita. So, I use Oak Parks router plate and brass bushings.
