A hundred bucks is a bit much when one can be made to suit your particular router for very little, as shown in this pdf, the block can, like my earlier one be made from hardwood and a flat ground or filed on the ends of the rods so that epoxy can be run down a hole above the rods to keep them from moving in use. The photo shows my original one, the measurements refer to the Makita router.The height and spacing of the rods should match your router. At the tips of the centre arrows can be seen the countersunk holes that the epoxy was poured into.

A circle cutting jig (fully adjustable) such shown by Harry has served me well.


PS I have moved your post to the jigs section.....

I've just remembered that my late friend and forum jig specialist Bob Jurgens made one similar to my simple one but instead of having to screw it to the router each time, a template guide was fitted to the router and the hole in the jig matched the guide so it was just a matter of sitting the router above the hole, now THAT is simple.

We had this discussion back in August. The jig does much more then just cut circles. Here is the link to the discussion(s).

http://www.routerforums.com/jigs-fixtures/47109-crb7-router-base.html

If you just want a circle cutting jig you can make one much cheaper. However, if you want to use this same jig to do several different operations then, in my opinion, it is worth the money. it saves shop space by combining several bulky jigs into one small package.

Several of the member bought them and general consensuses were that it was good quality and functioned as advertised in the videos showing the operations. I got mine from Rockler for around $80. They only listed them in the online catalog and were still charging the same price for the MK3 as the previous model. All of the details can be found in the August discussion link.

I bought a circle jig from Sears years ago .They also sell the adaptor for differant brands of routers . It wasn't very expensive and worked well as I used to build a lot of speaker enclosures and I could get the speakers and ports to fit perfectly

Update : kibosh that idea . I went to there site and it's no longer carried as far as I can tell . Never fails , you get a great product and they discontinue it :(

I've got a few M-Power items, and what i have is very well made and functional.

Furdo--you don't list your router inventory in your profile. While the consensus in the August discussion was mostly positive as i recall, there was a need to order (or buy locally) correctly sized rods for some routers, as Herb Stoops has found. I usually run a pair of Bosch 1617's, and the Bosch edge guide serves most functions as the M-Power, and is direct plug-n-play for the Bosch family so i chose to stick with it. On the other hand, if the only thing i had to work with was my Hitachi edge guide--i'd take any steps necessary to build another or adapt the M-Power.

My opinions only, your mileage may vary. Read the prospectus carefully before investing or sending money. Photos are serving suggestions only. In California, this product will ship with too many stickers to use. Past performance is no guarantee of future success. And...any other disclosure i may need to make!! :)

I agree with Harry that shopmade jigs can and will perform as well as any $100 jig. If you look in Bob Wearing's 2001 publication by the Guild of Master Craftsman Publications, Ltd (ISBN 1 86108 212 6) you'll find what we now refer to as skis, edge guide bar-mounted, circle jigs, levelling feet and a wide range of jigs for hand held router applications; my favorite is the 45 degree shooting board. Harry's several tutorials on his approach to circle jigs are testament for the quality and precision that can be achieved in shopmade jigs for a tiny fraction of what machinist-base manufacturers are asking for their tools.
The first attached photo shows a few of the Harry, Wearing and other source inspired jigs I've made over the years and the lot of the material doesn't come close to $100. I also attached a photo of the cover of Wearing's book but the copywright restrictions limit any other content.
There's lots of good information out there. Save your money and learn while building your oun jigs. Hyton's books will keep you busy for years.
