 You get what you pay forNov 28, 2007
By L. Algren
Having been satisfied with Grizzly machinery & tools in the past, I took a chance on this inexpensive jig. First, the ganged holes on one end are not drilled parallel to each other. Second, holes are not bored squarely to the face. Third, the clamping action is so sloppy that it can't center itself perfectly every time.
I could go on, but you get the point. This is a less expensive copy of a much better jig on the market. I shimmed mine with masking tape until it is useful. Still, I must shake my head and laugh at myself for buying this.

 Pretty goodOct 16, 2007
By U. Hoerhold
The jig works well and is easy to use. It's not as precise as I had hoped. The holes are not centered as precisely as I would like.

Works well, with sufficient careDec 29, 2007
By Alan Mazer
The title says it all. I've made a bunch of joints with this jig and they almost always turn out very well. However, there are a few things to watch out for. The piece you're doweling really needs to be clamped. When you tighten the jig around the wood, the clockwise rotation of the clamp will sometimes turn the jig slightly on the wood (clamped or not), giving you a slightly non-perpendicular hole; double-check this before you drill. It's sometimes a little difficult for me to line up the jig's marks with my own marks on the piece, but again, with sufficient care, it works fine. The manufacturer recommends using brad-point bits, but I've had no trouble with regular bits. In short, the jig is very helpful and can be used to make great joints, but you need to take your time and use some care.

So-so doweling jigJul 10, 2009
By keeena
This is a so-so doweling jig. Its the minimum I'd go for if you can't afford or justify a [the] really expensive one. 3-stars.
The reviewer Algren ("You get what you pay for") is pretty much dead-on w/ review. The resulting drilled holes in the wood are not perfectly perpendicular to face of the wood. I'd say its due to the fact that the jaws don't stay in the same plane. I think the alignment rods are relatively poor. When jaws are tightened, the end of the jaws deflect out from the workpiece. Meaning the jaws are closer at the side w/ the screw and wider at the base (where the workpiece is). This allows the wood to not sit perfectly perpendicular against the boring/jig face. Use shims or light clamping pressure. And yes, jaws do not 100% center the workpiece. But its slight and consistent. So this is still somewhat OK for face frames and such since you orient jig on the appropriate side of the 2 pieces you're joining.
Replaceable bushings are used for the 3 smaller hole sizes; the larger 2 (1/2" and 7/16") do not have replaceable bushings. Only the 3 smaller sizes can be drilled in pairs...assuming the jig's hole spacing is OK for you. If drilling the end of a narrow piece of stock, definitely use a scrap piece to keep jaws as parallel as possible.
For occasional hobbyist use, you'll definitely get by with this jig. Its not horrible; its a better design than a few others out there and I don't hate it. Note that some others brands which have similar designs have fewer hole options.
For pro woodworker w/ absolute precision or repeatability a requirement: look elsewhere. I bet better guide rods, true bushings, better tolerances and fine-tune capability would make this a perfect jig. Aka: The DowelMax.

 Great for heavy duty woodworkingJan 22, 2007
By Darren Curtis
"intendo"
This jig is extremely easy to use and very accurate. I use it to align thick slabs of oak for benches and tables and alternate dowels and biscuits for a strong joint. It helps align long planks and makes joints easier to make while minimizing sanding.
