Hello All,

I built a simple bookshelf style cabinet for my entertainment center and faced it off with 1x2 (.75x1.5) oak. Long story short, using the correct 3/4" depth setting and 1-1/4" fine thread screws, I cracked nearly all the joints, or the screw came out the side of the oak.

What did I do wrong?

Good question, Jens. I set the collar initially but I didn't check it after I started incurring the problem. And thanks to KregRep for the tips. All in all it wasn't a costly mistake so I'll just do it again. One tip I noticed was to use Kreg hardware, I am using pocket hole screws but they are generic from a large warehouse type chain store.

Thanks again everybody!

Did the collar slip up the shaft a little bit???

Thanks for your help everybody.

I seem to have done everything as you all have stated. One area though is where the rail meets the shelf front, I drilled my pocket holes on the underside of the shelf and screwed into the rail and nearly all points cracked.

Make sure the drilled holes are in the "rail" section,not in the "style".Drill all the holes,with the grain,so the "holding part"ends up in the end grain of the style. Adjust the stop collar down:it's too high,that's why the screw exits the side of the style. Hope this helps you out. Good luck!

Are both pieces same thickness or is one 3/4 and the other 1/2.I had same problem they did not hold

The "correct" 3/4" setting is a starting point. Sounds like you drilled just a bit too deep. You can adjust the collar on the bit accordingly. Also be sure the jig was set for 3/4". Check your setup on some scrap before drilling and fastening your finished piece. As for splitting the oak, were you using fine thread screws as called out? How close were you to the end of the oak? That will have a bearing on splitting the wood.

Adaptive Cutting System/Saw Blade

I have had the ACS for about a year.  Was wondering if there any other blades, like a Diablo, that will fit the saw?Continue

AutoMaxx 6" clamp not working

I have been using the Automaxx 6" clamp for two plus years, and recently the clamp is impossible to close the handles to secure the work and my jig. I cannot close the handles no matter how much pressure I can exert. I open the clamp to max to reset…Continue

New Kreg 720Pro

I saw the video Kreg put out for this new jig and had high hopes for it.

I purchased one today and am very disappointed with it.

First the docking station is extremely cheap. The plastic is pathetic. A Lego has more…

Not Pleased With Pocket Hole Construction

Several months ago, I purchased the Kreg K4MS so that I could build the Lego Table as outlined on the companion "buildsomething" web site which exclusively uses pocket hole construction.  I have considerable experience with conventional…
