Self Center Dowel Jig Kit Self-Centering Doweling Jig Drilling Guide Set

This was my first dowel jig. Looking back at the design I think it would have been improved by using ACME threads on the clamp. It doesn't need lots of pressure but a fast open and close thread would make this even better. Wish it was a bit more clearly marked as well. It works well other than those improvements.

The pre-drilled hole is slightly off of the measuring line which ensures each whole line up. This causes the pieces being joined to be slightly off.

This is by far the easiest doweling jig I have ever used! Nothing else at any price has come close. From the moment you take it out of the box the quality is evident, good heavy polished steel, screws that don’t bind, guides that are actually marked and standard, common sizes. I could not have asked for more of a tool at twice the price.

Testing Jig on 7/8" wood and found it does not center holes exactly in the board thickness. Worse yet, one end of the Jig is different than the other. One end is more accurately centered on the board edge than the other. Although the differences are small they are readily apparent to the eye. Given the nature of the design, I am not sure it could ever be the same on both ends or accurately centered on a board. The center turn screw introduces a difference between both ends because essentially the threads are an angled plane so one end tightens slightly different from the other end. The differences are small but clearly visible. I won't use this product and will spend over $200 to purchase a similar product that appears to be engineered for accuracy.

One of the best tools I’ve bought this year perfect holes every time

I've built a few pieces with this jig. I'm going to buy a new unit that is more accurate. I bought this one because it seemed like it would work well but it has a large error.

Tried it out freehand on some relatively straight scrap oak, making sure to be ultra-careful lining up the guidelines, and it worked great. I’m sure when I throw it in my vise it will be even better. Took less than 2 minutes to drill holes for three dowels. Strongly recommend this if you’re a weekend warrior/hobbiestEdit: man, I should’ve bought this a long time ago, just did a panel glueup and it couldn’t have gone more smoothly, thing is worth its weight in gold

I had been looking for a dowelling jig this solid and accurate for some time. I usually do not appreciate Amazon second-guessing what I may want, but in this case, I came away a winner. The Jig is quite solid, heavy in fact, as it is almost all metal. The way it operates insures as near a dead-on accuracy as you can get.
