Jasper Circle Jig Model 200 is rated 4.4737 out of 5 by 76.
Rated 5 out of 5 by from Huge Router Bits!This thing is so nice. I agree, it adds control, stability. Also allows use of large router bits to mortise flush mount rings. The 1 3/4 inch hole allows you to see what you are doing, and cuttings to clear. This clearance make this Jasper different (way better) than models 240 or 400. I really like using a 3/4 inch flat cut, 1/2 drive bit with this (the 200) to mortise flush mounts. Perfect for 99 percent of my circles too.

Rated 5 out of 5 by from A MUST have tool for any DIY speaker builderI have both the 400 & 200 model jig. I almost always use the 200. Its larger size makes it easier to control the router when cutting a circle. Also the 200 model can be uses to keep your router flat when flush trimming a baffle edge etc.No matter how careful you are you never get a perfect cut with a jig saw. Please with the Jasper jig you can flush mount your speakers.One tip; I always go up 1/16 larger than what the speaker size is because making the hole exactly the same size won't all the speaker to fit. No matter what make a practice cut on a scrape, especially if your going to flush mount, to make sure you have the jig set up perfectly. You don't want to make a mistake and ruin your baffle with a wrong size cut.

Rated 3 out of 5 by from AcceptableThis is acceptable for the $$. Reason for 3 stars is it has a tiny hole for the router bit (fits 1/4" only) No doubt because the measurements are calibrated for use with a 1/4" bit. However you will need to bore it out without breaking the cheap plastic to use another size which I managed to do with a high level of stress. Also the screw holes used to attach this to the router base are not countersunk. Poor / lazy design and build on both those points. Also, the formula provided to use another bit width is incorrect, fortunately I performed my own calcs. Despite all that, I'd have to say its worth the money and good for someone routering once in a blue moon, but not on a regular basis.

Rated 4 out of 5 by from Better than a jigsaw (if you have a router).This 365-250 Circle Jig router adapter works pretty well for me, and is fairly easy to use. I have an adjustable speed Chicago plunge router from Harbor Freight, and the jig does fit to all three holes in the base (but at an angle to the user). Do not remove the plastic base plate on this type of router, it is necessary for proper router operation. Mounting the Circle Jig requires three of the longer screws into the spare router holes on the base, but only two appropriate screws are supplied with the jig. I bought a third screw at the hardware store, just make sure the screw head is low enough that it doesn't exceed the counter-bore height of the jig.The router instructions indicate not taking a cut deeper than 5/8", so two 1/2" pass cuts were necessary on 3/4" particle board. I used a 1/4" up-spiral bit purchased from Lowe's, with the router set to its highest speed for this realtively soft product. In cutting ten holes, there was no burning or burnishing of the wood or router bit.You really need to use another board underneath the one being worked, in order to keep the cutout disc (and guide pin) from tilting away and ruining the cut. The jig's instructions indicate to use double-sided tape to hold the workpiece to the underlayment, however a couple clamps can (and did) work just as well and were much easier to manipulate. Also, recognize that once you complete a cut-out, there is no longer a center to make another cut. The reason I mention this is because the 6.5" speakers (292-426) purchased from Parts Express indicated a 5-5/8" (5.625") hole cutout. On the first cutout I set the jig for just that, and the speaker didn't fit flush to the surface; so filing of the hole with a half-round rasp file was necessary. For the remaining cutouts I set the jig for 5-11/16" which worked better, but still required a minute or two of filing per hole to get the top edge of the cutout at about 45 degrees. The hole diameters measured accurately enough, so it wasn't the jig or router setup.I measured the Circle Jig guide pin at 0.124" so an 1/8" (0.125") pilot hole per the instruction did work, however when placing the setup into the pilot hole, the pin would push up into the router (5-11/16" is next to the router base) and had to be pushed back into the wood with pliers. The other aspect was that the center hole of the jig is meant to be softly hammered out once the jig is setup on the router. However, with my router, the center piece was trapped in place by the router and could not be taken out once installed. So, I first removed the center disc and then placed it just partially back into the jig, carefully set up the jig on the router, and then popped the center disc out by hand.Ultimately the jig worked well, and was an easy way to cut 10 nicely round speaker holes into a wood panel.

What do i do if I need to cut a perfect hole with the diameter where the hole in the jig is blocked by the router base?

Asked by: Ando
You may need to use a different type of router called a plunge router that allows you to sit on a short centering dowel with the jig flat against the object you are cutting. The tool in the router is held above the face of the object until you plunge the tool down to the tool stop built into the router. This way you can start with everything in place without a long centering dowel.
