Tools and Hardware Reviews of Grizzly G1874 Improved Dowel Jig
Customer Review: So-so doweling jig
Summary: 3 Stars
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.
