Bosch Router Table

The Jasper Router Circle Cutting Jig is ideal for the speaker maker. Designed primarily for making smaller speaker cut-outs, particularly for tweeters and midranges, it can also flush mounting speaker drivers. Converting a plunge router into a precision circle cutting device, the jig allows the craftsman to make 120 different size cutouts in 1/16-inch increments. The cutouts range in size from 7-to-18-3/16-inches. Perfect for tweeters and small midranges, it cuts holes from 1-to-7-1/2-inches. Manufactured from cast acrylic 3/8-inch thick, the jig can be left on the router as a sub base, and be used with MDF, plywood, particle board, solid woods and plastic sheet. Made in the U.S.A., this circle cutting jig mounts directly to the base of 19 different models of plunge routers including Bosch 1615, DeWalt 621 and 625, Freud FT2000E, Hitachi M8V, TR12 and M12V, Porter Cable 690 series and 7539, Skill 1823 and 1835, and all Sears, Ryobi and Makita models.

Most helpful customer reviews 9 of 10 people found the following review helpful. Almost a 5 ... By JL The circle jig comes with a 1.5" pin to be inserted into the work piece and into the jig. The jig being attached to the router then rotates around the pin giving you a perfect circle. The only problem I ran into is if you have stock less than 1.5" thick and you wish route part way into the wood and the jig pivoting point you need to use is under the router base, a hole must be drilled completely through the stock. Would be nice if they supplied an additional 1" or .5" pin. (I made one out of the shank of a 'new' eighth in. drill bit - holes in the jig are very tight tolerances, no slop.) 4 of 4 people found the following review helpful. Works Well By M. Gaipa Installed easily and worked well. I used an 8D finish nail with the head cut off for the pivot instead of drilling and using the provided dowel. I wanted the cut-out for a project but didn't compensate for cutter diameter and was undersize at first attempt. Ooops. An aluminum version would be better. 4 of 4 people found the following review helpful. Works well but too fragile. By Matt de Vries This thing works great, is precise, and repeatable (which is it's primary value over some other jigs including homemade ones) Unfortunately, the material is just not up to being mounted and dismounted a lot, so use care and watch the torque when mounting it. It's one of those odd tools. Given the fragility of the material, and the fact the cheap materials means there has to be a HUGE markup, it is overpriced. However, it works very well if you don't break it. It's the kind of tool after using I'd consider paying 3 times the price to get one in laser etched anodized aluminum rather than plastic. I give it only 3 starts becuase made out of acrylic, it's essentially a consumable and WAY too pricey for that. See all 15 customer reviews...
