Great idea. Bought a 6mm, 45mm long, hex drive bolt and used it instead of the replacement knob. works great, cost 43 cents. Thankyou very much for the idea
Question... I have the same router. If I scribe a line and set the router over that line by the centeri,g reference marks on the base of the router, the bit does not center itself on the line telling me the reference marks are not centered on the spindle. How does yours align? Thx
Mine align with all 4 sides and their center marks. That’s why they’re there and I don’t see how they can be off or adjusted. The center reference marks are the center of your bit, not the edge of the bit which can change depending on its diameter.
Minimum = 3 5/8” radius or about 93mm Maximum for the stick rods is 17” radius or 143mm. To switch between minimum and maximum you would need to put the pivot knob in either the further or closest position.
Mark G I doubt you can do that with a jig for this router as the base is too large and would stick out past the radius. You’d have to use a trim router for that. However, I just bought a hole saw set so I can use them for smaller holes and for cabinet installation.
I picked up a knob locally here bit you can get empty knobs that can accept any bolt because of the hex hole at the top of the knob. Toolmonger wrote a post: toolmonger.com/2009/03/03/always-have-the-right-knob-for-the-job/
For the rods that came with the 1400 router and my method, you would get a 16" radius so a 32" diameter circle but if you got longer 8mm (5/16") rods from somewhere you could go beyond that. As far as the bolt threading for the knob I did find some online but just get the type where the bolt goes through and bottoms it's hex head in the top of the knob. Then you can switch it out for whatever bolt you want as long as the hex head is similar in size to fit the knob hex pattern inside.
John Sprofera Peter Parfitt has a cool design for a circle jig. I made mine from a scrap piece of 1/2" ply. Not sure if I still have it but I can make another one in 10 minutes. For a pivot pin I took a framing nail and cut it to about an inch in length and sharpened the point. Plus, with Parfitt's design you can stand in one spot and rotate the router and the same side of the router faces you for the whole cut. Very convenient when you're dealing with a vacuum hose and power cable. He uses a guide bushing. If you see it you'll understand how smart and simple it is. I tried to look for it but he's got a lot of videos.
The thumb screw out of the standard fence guide which comes with the router is long enough. I just use that.
Just use one carriage for smaller holes.
Awesome! The knob from the edge guide works perfectly btw.
Great idea. Bought a 6mm, 45mm long, hex drive bolt and used it instead of the replacement knob. works great, cost 43 cents.
Thankyou very much for the idea
Used this trick today: worked well and felt very controlled the whole way. Thanks.
Good thing I found your video that I need , thanks
This worked perfectly for me. Thanks for the great tip.
awesome.
Very nice idea!
Used it now. Works flawlessly. Would it be feasible to buy longer steel rods if you want a bigger circle, or would they flex too much?
I wouldn’t think you’d notice flexing if using two correct diameter steel rods. If the bit make a 1/16” deviation I don’t think anyone would notice.
Great idea and easy to do.
Good work brother.
15/64th drill bit. *shivers*

This is a great tip but Googling M6 knob has scarred me for life.
They’re all over Amazon and eBay. You may need to shorten it but they’re not scarce.

Genius
Very clever
Hi. What's the minimum radius of the circle?
Minimum = 3 5/8” radius or about 93mm
Maximum for the stick rods is 17” radius or 143mm. To switch between minimum and maximum you would need to put the pivot knob in either the further or closest position.
What is that attachment (hinge) that you have for the track that allows it to move up and out of the way?
It comes with the Festool MFT/3 system
Look up "MFT rail hinge" and you'll find a number of them ranging from Festool to DIY.
A great tip. I also need to cut a 1.625 in diameter hole. Do you have an idea how to do that with the router?
Mark G I doubt you can do that with a jig for this router as the base is too large and would stick out past the radius. You’d have to use a trim router for that. However, I just bought a hole saw set so I can use them for smaller holes and for cabinet installation.
what kind of cutter did you use here?
Just a simple upspiral bit to plunge and then cut.
I like your video. Can't seem to find the Metric knob m6 coarse. Can you share with me where to purchase? Also whats the max circle I can cut?
