Nice template [Posted on 2000-11-13]
I've just recently build a bookcase with this jig. The set-up was fairly simple. The video that came with the omni jig also explained this set-up a little bit. The manual recommends a setting of 23/32 for the depth. I used 3/4 setting for mine. I was cutting 3/4 mapple. It helps too, if you have a depth gauge. I wish the jig was a little bit stiffer. The router can actually move the rails a little bit. However, once made the dovetails slide together nicely. Also it helps if you cut the slot with a straight bit first to hog-out most of the wood. After that the dovetail bit doesn't have to work too hard to cut the slot. Another thing would help also is to wax the templet and the base of the router.

This price for a piece of machined aluminum? [Posted on 2003-11-13]
OK, it works and works well, other than the sloppy stops the Omnijig employees.

But this price for a piece of machined aluminum? What does it cost Porter Cable to make this accessory? $2?

PC does have to cover the development costs and should charge a premium for a jig that is somewhat of a standard in woodworking. Check out the price of the Omnijig. Trust me, you've already paid for this accomplishment when you purchased the original jig. And the design of this jig hasn't changed in years and years. PC is way behind the times.

I'm thinking (hoping) that there is a special place in hell for those individuals in companies, like Porter Cable, who decide to rape their customers, who have already paid a hefty tab for the jig, when they want to purchase an accessory for that jig.

Shame on Porter Cable. If had it to do over again, I wouldn't buy a PC dovetail jig.

Good piece of hardware [Posted on 2006-04-04]
This is a good piece of hardware. But a couple of things to be aware of: 1) This is a "tapered" jig. So if you look carefully on the front right side of the male slot, you'll see it's about 1/8" narrower than the left side. This is how it gets one side tighter than the other. One side slides in easily and eventually gets tighter as the male part gets increasingly wider. 2) Pay particular attention to making sure your M and F pieces align on the left side and that your boards are the same width. This important for achieving the tight fit at the other end of your boards. (I first did a test cut using 2 different widths of boards, and they didn't fit, and I freaked...at first)I agree with other writers that the whole OmniJig could use a major upgrade, putting precision adjustment knobs instead of trial and error stop blocks for example, would really help....Tom O'Brien...All Quality Woodworking
