Circle cutter

[SlugButter]

Circle cutter finally gave up today. Had to make one temporarily until I can get a decent one. What universal circle cutters have any of you used that worked well?. I have 2 different routers, a Bosch and a cheap Hercules from harbor freight. 1/2 inch shank. The homemade way is just too cumbersome and slow.

I would like to know this as well. My current jigsaw method isn’t as neat as I would like.

Jasper circle jig has always worked well for me. It's just a plate with specially laid out holes for center and outside radius.

I've always just cut out a circle template on the waterjet at work, cut a rough hole with my jigsaw, and then used my flush trim bit on my trim router. Probably not helpful at all considering you probably don't have access to a waterjet, lol.

If you want a simple solution, find a local plastics shop and have them make you templates out of acrylic. Most subs use a common Cutout so you only really need 6 or so different ones to cover most 8's through 15's.

Jasper Jig's patent is up so there is many on the market that are the same exact thing for 20.00 or so on ebay or amazon.

I use a Milescraft Large Circle Jig kit. The kit comes with a 1/4" shank bit, but it'll work with any bit.

Milescraft Large Circle Bundle - Includes CircleGuideKit and TriGrips 73600003 - The Home Depot

Cut small and large circles from 1.5 in. Dia to 52 in. Dia with the CircleGuideKit router accessories guide. With the included TurnLock base plate, this product is compatible with most routers. There is no longer a need for that homemade circle cutting jig, the CircleGuideKit does it all for you...

Nice. Last time I looked for a circle cutter jasper was about the only decent one. I remember when 3M still had the patent on the paper/tape masking tool. Stupid fvcking thing was 35 dollars for 15 cents worth of plastic back in the 90s.

Yup.. some bull$hit.

IIRC Toolmaker made an aluminum CNC circle jig.

Mobile solutions had a circle template set for use with a router. But it's pricey and not really worth it unless you build for a living and even then I'd still buy a jasper jig or the likes

If you use a router/jig, ensure you screw the baffle to the table. Example:

Man.. That turned out Awesome. Really enjoyed watching that enclosure come together. Very interesting. Thanks for sharing man. I enjoyed it

No Problem. I was deep in the box building rabbit hole on YouTube and I kept seeing people mess up the circle cuts. I was like damn, I hate when that happens. Then I seen some videos by 210 Designs, the one I shared. He points out to screw the baffle down. Genius idea, never even crossed my mind. Something so simple could save on that little bit off frustration.

I have a special table I clamp the baffles to so I don’t have screw holes in my wood. i hate that. I very rarely cut the holes after installing the baffle on the box. Most of the time that’s not really possible anyway because of box construction methods. The hardest baffles to cut on are the small ones. This one was for a 6.5 and I did have to screw it down because the clamps got in the way of the router. I think I’m going to make wood or acrylic templates for all the common sub sizes and make a special table so I can just clamp down the baffle and use my flush trim router bit to cut the holes.
