Screws not holding in 2x6 douglas fir - Kreg Owners' Community2024-03-29T09:53:06Zhttps://kregjig.ning.com/forum/topics/screws-not-holding-in-2x6-douglas-fir?feed=yes&xn_auth=noThe "correctly" part of this…tag:kregjig.ning.com,2017-02-20:2900167:Comment:8699162017-02-20T17:03:15.251ZMichelehttps://kregjig.ning.com/profile/Michele225
<p>The "correctly" part of this might be in question. If we put the wider piece between fence and blade, I'd have to readjust fence after ripping down one side since the overall width of course just changed. So rather than do that I just ran them all through with the small part between fence and blade. Admittedly, by no means the safest or preferred way and certainly a "do as I say, not as I do" situation.<br></br> <br></br> <cite>Ken Darga said:…</cite></p>

Well apparently the faces were the issue. We took about an eighth off on the table saw and so far two boards are together tight and strong. Guess it was just dumb luck last time. Good excuse to get the old jointer going that someone gave me because ripping an eighth off with a table saw is somewhat dicey.

<p>I've been following your thread Michele. Not sure I have anything to add further other than speculation on my behalf. So here goes.</p>
<p></p>
<p>Just throwing something out there;</p>
<p>Were these boards joined together right away after bringing them home? Was there a sudden rise in humidity for more than a day or 2 or 3? Then the boards joined together followed by a drying out spell for the boards to shrink? Have you tried to re-tighten the screws?</p>

<p>Were the edges exactly square to the faces?</p>
<p>Were these boards cupped across the face? If so then the edges cannot be square to the face.</p>

<p>I was wondering about too much torque actually since on visual, the screw heads are plenty far enough into the pocket. All Dewalt power tools around here </p>
<p></p>
<p>I'm going to take some short pieces (about 12" - what's left after chopping the 12' board down to the 42" pieces I needed) and see how it does with just 2 screws after I rip off the rounded edges.</p>

<p>Be careful with an impact driver. Mine can drive a screw clean through even thick boards. You don't want to overdrive the screw through the pocket hole.</p>

<p>You should use a impact driver. That is what the cabinet installers use to screw kitchen cabinets into the studs in the kitchen wall. After using a drill, one can find that one can take a screwdriver and still drive the screw futher in. Also, the brand of the tools makes a difference. Contractor grade Dewalt, Makita, and Milwaukee tools work better than other cheaper brands.</p>

<p>On the rounded boards you are fastening together, some of the holding strength is going into the curved area which causes the weakness in the hold. You can find two pieces of flat edged boards and join them with a kreg and it will hold solid. At a store like Home Depot, you can take the common pine boards or the more expensive select pine (without imperfections), they have flat edges and will solidly join. <br/> <br/> <cite>Michele said:</cite></p>
