"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…"

"Michele, Ripping off an 1/8" is not an issue on the table saw, when done correctly. The wider piece to be positioned between the fence and the blade, so the narrow strip will be on the outside of the saw blade."

"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…"

"I've been following your thread Michele. Not sure I have anything to add further other than speculation on my behalf. So here goes. Just throwing something out there; Were these boards joined together right away after bringing them home? Was…"

"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  I'm going to take some short pieces (about 12" - what's left after…"

"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."

"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…"

"And especially since it's happening on every stinkin' board and we've done this same build before with no issues. I have the torque setting at like 11 or 13 on the drill tho I did think maybe I should try the impact driver (Christmas…"

"It is just like mentioned. The pieces of wood have to be square on the edges where the wood is joined together. The rounded edges have to be cut off.  When I use the construction lumber from the big box store, I trim off the rounded…"

Tim Grace replied to Michele's discussion 'Screws not holding in 2x6 douglas fir'
"My thought on the wood is that the screws may have hit "soft" spots that are further from the heart of the tree. As I think about this, it doesn't make sense.  Especially since you are drilling & driving into both boards. The…"

"What in the lumber would cause this do you think? I can get some plates done up to see under each shelf to stiffen it up but only after I give a good yank on it and make sure it's not going to pull apart. Since I need to beat this with hammers…"

Tim Grace replied to Michele's discussion 'Screws not holding in 2x6 douglas fir'
"Whenever I edge join 2X lumber, I cut the rounded edges off, either using the table saw or jointer.   I also will edge glue to add the strength and stiffness. The fact that you've built in the past and had no problems, tells me it may just…"

Screws not holding in 2x6 douglas fir

Hi all,I've got a mystery here. Trying to make a bar cart out of 2x6 douglas fir, 42" long. 3 shelves with 4 boards each. We have done this exact same design before in the fall and had no issues. I'm using 2 1/2" coarse thread screws. Each of the 3 joints / shelf has 5 screws, 2 going one way, 3 the other.The issue we're having this time is every single shelf has "flex" to it. I do NOT get it. I've verified the settings on the drill bit via the tool AND a measurement of 4 1/8" from stop to…See More

"Michele, Peruse the instructions a couple times, to ensure you've covered all steps. BTW---it's beneficial to make test pieces of the same material and size, before proceeding to the workpiece."
