Trim routers are great for small operations. I wanted to make some precisely fitting holes for flower pots, but the circle cutting jig for my full-size router was too big. So I decided to make a small version for my trim router. Additionally, I wasn’t thrilled about the fence that came with my trim router, and wanted something that worked better.
How about a router jig that had both a circle cutter and an adjustable fence for dadoes, grooves and flutings? This is what I came up with, and how to make it.
Start with a piece of good 1/2″ plywood. Make the base 7″ x 18″ with an over-size 1/4″ slot cut down the center to accept a T-bolt. Add two guides 1″ X 12-1/2″, spaced 3″ apart.
Mount the router base centered side to side and 3″ from the front edge of the jig base and cut a hole for the bits to go through.
The circle cutter pivot pin is a 1/8″ x 1-1/4″ machine bolt, double-nutted with a star washer mounted in a 3″ x 7″ block. I positioned the bolt 1″ back from the front edge.
The pivot bolt is held in place with a counter sunk nut on the bottom. You also need to drill a 1/4″ hole 3″ back from the front edge to receive a 1/4″ T-bolt.
The under side of the jig base is slotted to receive a 1/4″ x 1-1/2″ T bolt. Note that the bolts for the router base also must be counter sunk.
The sliding fence is 7″ x 7″ and the sides are 1″ x 7″ so the fence will wrap around the jig base. Also note the oversize slot to receive the T bolt.
The fence and the pivot block can both be mounted on the base for storage. A great way to make sure all the parts are there when you need them.

That is a good jig, I love it!
like working with a router
Yes I made some thing similar many years ago for my larger router, make wheels, circle cutting up to 48″, works great
looks like a real helper
Hi, where are the pdf plans for this jig to download it looks good
Hello. I am sorry, there are not any additional materials related to this article.
Interesting plan. For those who are not getting the idea here the fence is to ride along the edge of material for dado cuts. I too was looking at it a bit wrong thinking the slot was for dado at first til I saw the sled attachment.
why can’t I see the trim router jig videos or plans. I am a gold member

Sorry to sound so ignorant but I just got a trim router recently and I am a relative newbie to woodworking. i just made a project for my wife where I cut dadoes in the base board. I clamped a board to my base board so that I would have a guide. This sounds like a good jig but I don’t understand how it works. Couldn’t there be more photos or a video of the jig actually being used?
Thanks for your question. This particular jig might be overly complex for your needs. Perhaps take a look at these other resources:
You also might consider using a table saw for cutting dadoes.
