Yes! Quick release! That implies no more limitless screwing and unscrewing to make adjustments. And no tools required to make modifications, after it's put in the router.
A single wheel sets the diameter and can be popped out and in for fast established.
While I used plastic for the wheel in mine, the original plywood one needs to last a long time.

I was thinking if John were to add two more (one at each end) they could be used to lock the base in position.
Only thing I’d do differently is use a threaded insert in the knob as it will last longer than the wood threads
I like it, looking at the thumbnail i thought you’d brought something rather than making it, i was shocked ๐
Excellent work sir.
Nice size. You could get extra fancy with the nut, maikng it like a quick release quill stop. using a threaded furniture cross dowel for the plunger half nut. I think they are M5.
Wow! Cool jig. Well done sir. I have a tip regarding wooden machine screws. I use some water thin CA glue on the threads to make them tougher. In an application like your circle jig, the CA goes in the hole right befor you run the hreaded rod rod back an forth being careful to keep the rod moving so as not to glue it in the hole. A little wax on the rod after the CA has dried makes it work smoothly. I tried it once when the idea first came to mind, and it’s become a regular step whenever I’m cutting machine threads in wood. Thanks for sharing this well thought out jig.
I dunno, it seems to me that you are just going round and roundโฆ ๐
Great idea, well executed!
Thanks
All i can say is your work of wood makes me envious. Excellent video and product.
Awesome ๐
Thanks for the video!
Thanks ๐
Very handy jig, well done
Your tools are crazy sharp amazing
Nice work John!! Great Idea. Headed out to the shop now to build one!
I like it. Solid design. Better than I could think up on my own I think. Although I think I would modify it a little.
The screw knob thing looks a bit fiddly to me though. It will likely work a long time. I don’t doubt that. I might would just use a solid block for the threaded rod to go though, then drill and tap an intersecting hole in the side of said block, and run a bolt with a home made head glued on for grip as a set screw. Just seems simpler to me, although you would lose any fine adjustment beyond just loosen, bump, retighten, try, loosen, bump, retighten.
My favorite projects of yours are always the small shop tools. Your mini cross-cut sled has gotten a lot of use in my shop.
Really nifty idea. Gonna put this on the shortlist โ to buildโ. Great project John ๐
Fantastic circle cutting jig John! Will definitely be making one like that! Thanks! ๐๐
Great jig John. I see one of those in my future.
Another great jig ๐ Wouldn’t it have been simpler to have a single block which the threaded rod goes through, with a threaded knob going down through the block and pressing against the threaded rod to hold it … quick release built in and nothing to really wear out … another method would be to have a split in the block with the knob pulling the sides together to clamp the threaded rod in position!
That’s so cool. You’re making me want to buy a router!
Enjoyed seeing this come together. Your stuff is so complicated, yet so simple.
John is the Tesla of the wood shop!!!
So glad you still take the time to share your creations. Thank you
