Works great! I have yet to attempt angels but I have an upcoming project for it. Works just as well on narrow and thick wood. Meets my expectations and as usual, the customer service at the Ontario Rockler store was fantastic.

Get the screws in straight for great results!
As a beginner, i built a bench with aome challenging details i found this jig to help place straight screws into the frame of the bench. I was also using dowel pins to secure the slated seat style. Great tool to eliminate screws going in poorly!

The product does what it says. I also used it laying on a board to drill a hole perpendicular to that board.

The larger max thickness of this jig makes it more appropriate for most of the wood I work with.

just bought my first dowel jig 07500tk can I buy bushing to change hole size ?
Reggie on Mar 28, 2016
BEST ANSWER: No. This doweling jig does not accept drill guide bushings; it has six different size drilling guides built right into it.
Can it be used to join edge to surface?
Freddie on Oct 12, 2015
BEST ANSWER: If the edge is thick enough, you can use the jig to drill dowel holes. You will need dowel centers to align the edge holes with the surface. If you set the jig on the surface it may help guide the drill for the surface holes.
Can all the holes be the same size?
Arlow J on Sep 17, 2015
BEST ANSWER: Yes, they can all be the same, or mixed sizes, or just one hole as is your choice. Mine work very well when I joined the head of a rocking horse (2 inches thick) to the body. They slid together perfectly without any binding or misalignment. I wish I would have had one many years ago.
My porch railings need additional length due to wood rot. The supplemental length will be 5 inches at each end. I would like to dowel join the supplemental stock to the existing stock by drilling perpendicular through the supplemental stock into the existing stock to a depth of about 3 inches. The alignment needs to be perfect and the total hole length needs to be 8 inches. Can this be done with this jig?
Bob S on Dec 11, 2015
BEST ANSWER: I'm assuming your railing is 2x4.... In the case that the railing is 2x4 this jig will work perfect.... I would recommend using the largest dowel possible.... I'm not sure how you'll clamp this long piece with glue but I am certain that the jig will suit your needs
How wide will the jig open ?
A shopper on May 31, 2015
BEST ANSWER: It opens to 6 inches. It is a sturdy and precision made tool. I used it on 2 1/5' lumber and it worked perfectly and the jig centers right on the mark. This is the first time my two pieces of lumber slid together squarely and I didn't have to pound them together to fit. It is a little pricey but I use it quite often so it was a good buy for me.
how easy is this tool used to dry fit before glue up.
Mack D. on Mar 5, 2016
BEST ANSWER: It is extremely easy. Takes out all the measuring you normally have to do to find the center of the corresponding dowel hole. Really great for attaching tabletops or any flat surface to carcass work. They pop out easily with a pair of pliers.
Does the jig work as well on smaller stock, such as 1/2 or even 1/4 inch material?
Charles R on Nov 3, 2015
BEST ANSWER: Yes. It works great on all sizes. I have used it on many different thicknesses.
I need to drill holes for stainless cable to pass through on 4 x 4 posts. Will this product insure the holes will align on both sides of the posts?
Dennis L on Nov 8, 2015
BEST ANSWER: I used the doweling jig for the same purpose and it worked great. I used brad point drills and drilled from both sides of the posts to avoid blow out from a drill bit exiting the wood. I installed my cable at on 3" centers and had a template with holes on 3" centers that I used to mark the 4 x4 posts. These templates are available commercially or you can make your own. Once I marked the posts I attached the doweling jig and proceeded to drill. The doweling jig automatically takes care of the left right centering and the depth of the jig alignment hole was sufficient to keep me square to the post. I also had a level that was built into my drill that I used as back up conformation that I was level with the drill. Ric
I need to join 2x6 side rail to a 2x6 up right post, will locate 2 1/4" holes at the side of the 5 & 1/2 face of the post and align them to matching on the end of the side rail?
Bob G on Mar 7, 2016
BEST ANSWER: Not sure if I fully understand what you are trying to do. Are you trying to drill holes in the center of the 5 1/2 inch face of a 2 x 6, and then attach the end of the 1 1/2 in width of a 2 x 6 to it by drilling holes in the center of the 1 1/2inch width? If so, then yes the drill jig will work. It will drill in the center of any piece of wood up to 6 inches. If you want to off-set the holes from the center, it will not work.

What is the hole layout in the block (dia & spacing)? Can I drill 2 of the same size holes without moving the jig?
Mark B on Jun 20, 2016
BEST ANSWER: the block has 5 different sized drilling guides alined along the center line of the centering block from front to back. You can't drill holes of the same size without loosening and sliding the jig to the next hole location, but there are centering lines etched into the side of the block at the bottom that line up with the centers of each of the 5 guide holes, so lining up the jig is fast and very easy...and accurate. All you need to do is draw a pencil line perpendicular to each location where you want to drill and slide the jig until the etched line and pencil line intersect.
can this Jig be used on smaller thickness wood as well as 4" stock?
john l on Apr 7, 2018
BEST ANSWER: When the jaws are completely closed, there is about a 1/2 inch gap between the outside walls, allowing for the thinnest stock to be just a little over 1 1/2" thick. Hope this helps.
Can this jig be used for off centering holes?
David D on Jan 13, 2018
BEST ANSWER: I was able to off center holes by adding a shim or small piece of lumber to one side of the jig. As long as the combined thickness of the shim and the lumber doesn't exceed the size limitations of the jig it is fine.
Will it ope to slightly MORE than 6 inches as my cedar posts that I am going to drill for cable are slightly larger than 6 inches?
Bob S on Jun 11, 2016
BEST ANSWER: I opened mine all the way and it was 6 1/8". It wouldn't go any more unless you took the handle of, then maybe another 1/8" but I didn't try that.
I want to join 3.5 " table legs and 3/4" x 4" rails . Will the next 20262 thick timber self centering dowel jig handle this task?
