Revolving Turret Doweling Jig is rated 2.3 out of 5 by 12.
Rated 1 out of 5 by from Don't Buy It Absolutely worst doweling jig ever made, should be taken off the market and made better . Jig wobbles and will not center; dowels DO NOT join boards evenly.

Rated 2 out of 5 by from Some use, but not worth it.... I recently bought kreg jig and it's been a great & useful tool. When I saw this doweling jig I hoped to bring that kind of efficiency and accuracy to dowel joints. But I was sorely disappointed...The theory looks good, but I can actually make these joints by hand better and easier. You must draw across your 2 pieces with a square (same as by hand) but unless you draw center lines down each piece as well, you will have a difficult time using their graduated scale to find the hole location...If you do, you're already halfway to doing it by hand anyway....Next I assumed that the drill bit was made slightly on the small side so the dowel would fit tightly, but I was wrong. That combined with a certain amount of "wobble" in the turret guaranteed an extra large hole that the dowel falls right out of.......Mysteriously, the kit includes some pieces called "dowel & tenon centers", but their use is NOT covered in the booklet. There seems to be one for each hole in the turret except one, and 2 duplicates...They can be used for marking centers for drilling, but all in all it is easier AND more accurate to do this work without the jig...Wish I had my $30 back. Bought it last fall and didn't get around to trying it until following summer, so can't return it.

Rated 1 out of 5 by from This product is too weak and sloppy for accurate drilling. The rotating drill guide is held in place by a spring to make it easy to changre hole sizes but provides very little support for holding the drill perpendicular. The rotating drill guide is aluminum which wears out quickly. The clamp slips easily, I had to glue sandpaper to the surfaces to help hold the jig to the work piece. The slide that carries the rotating drill guide wouldn't stay in place and the boss for the the knurled knob broke when I tried to tighten it enough to hold the slide in place. Drilling an accurate perpendicular hole isn't possible.. It is easy to adjust which is the only redeeming feature in my opinion. In order to be a useful tool it needs much longer hardened drill guides and a beefier construction in general.

Rated 1 out of 5 by from not accurate enough This jig is not solid enough to provide accurate enough results. The holes on mine are almost a 16th of an inch off of their center line. It takes so much care and tedious setting up to get the hole right where you need it that it defeats the purpose of having a jig. This doesn't make the job any easier or give better results because of the amount of effort that has to go into getting it all to line up properly.

Rated 5 out of 5 by from Excellent when used carefully This is an excellent tool. I used it to construct a dining room table and a garage door section. What a user needs to know is a couple of tricks. 1. clamp the boards together with the finished sides facing out and the rough sides touching each other with the edges even. 2. square lines across where the dowels will go. 3. clamp the jig into position, MAKING SURE IT SITS FLAT, on the right side board locations and drill. 4. turn the jig around 180 degrees and clamp jig into position MAKING SURE IT SITS FLAT, on the left side board locations and drill. 5. dry fit without fully clamping together. 6. glue and drill. Be diligent. This tool is meant for precision work, patience is the key. I'll be using this tool again to make some radiator covers in the coming weeks.

Rated 4 out of 5 by from dowelling jig I'm just a hobbist but i take pride in my work. With that said this tool works great and for the money you can't beat it. I'd never made these joints before and right out of the box was able to use it with GREAT results.

Rated 1 out of 5 by from Save your money Recently attempted to use this unit on a project for my grandson. Not accurate at all. If you're going to purchase a doweling jig spend the extra money and get a quality unit rather than waste the money to purchase this unit and then have to purchase a better one. Do it right the first time.
