Thread: Why does my pocket hole joinery ?

  1. #46
    I've used a number of different drills but I think they're all 18V
    For the gate, probably a Ryobi
    For that cabinet, maybe a Hercules

    Usually my torque is at max for drilling and 9 or less for driving the screws.

    One other thing.
    The screws seat outside the holes and don't go in the pocket hole.
    Like in the right hand photo
    It looks like you jig and drill are not set up right. Here is what a properly drill hole should look like in 3/4" plywood.

    Note that the hole should be oval and not squared off as your holes appear to be. You should not be able to see the heads of the screws when they are in properly drilled holes and fully seated.

    I believe you may be right, Lee.

    I think I am doing everything properly but, apparently not.

    I think my jig and bit are set ti the size of my material.
    I clamp the wood to the jig to drill.

    Drill bit?

    I have a new, unopened bit here.
    I can try that when I head out in a bit to test and practice

    Double up the rails, sandwiching the stiles between along with a diagonal brace. Run your slats across, all set. No pocket screws. Pocket screws aren’t going to remain tight in outdoor work for very long.
    Bumbling forward into the unknown.

    Note that the holes I showed were drilled in 3/4" plywood. Can you show photos of your setup before your drill a hole? Specifically show how far the tip of the drill sticks out of the jig where the wood would be if you had the drill fully inserted.

    You shouldn't be having this much trouble.

    Regarding the plywood, first, be sure you're using the correct screws. I've never seen blue pocket screws. Are those Tapcons?? Second, the hole isn't deep enough. You shouldn't be seeing the head of the screw if properly seated.

    I've not had many problems using Kreg coarse screws in plywood. I typically use 1 1/4" screws.

    Check your setup:

    I would go over the instructions for the correct screw length and drill block setup.

    In sheet goods of any kind, you have to be careful how much you tighten. I prefer to use a drill rather than an impact driver because I can regulate the torque better. That said, once in a while you'll hit a pocket in the ply.

    BTW, I would cover the gate with chicken wire on the outside to keep the goats from standing on it.

    I will do that, sir.

    Robert, I didn't think I should be having this much trouble, either.
    I am only using authentic Kreg screws.

    I've not needed any fine screws yet because I've only tried to join plywood or pine.
    I also use 1-1/4" screws in 3/4" material

    I've never used an impact driver, only drills.

    I'm thinking the problem isn't driving the screws but something in the process prior to that.

    I'll get all my data in a bit and post it

    Thanks, everyone, for sticking with me

    Those look like Kreg Blue-Kote pocket hole screws. They have extra layers of corrosion protection coating for outside use.

    They haven't figured it out yet

    Here's a photo that might help.

    Here is an improperly drilled hole where the drill depth is too little.

    I may have found the problem for this last time but don't believe that has always been the case.
    And not sure why this time unless the set screw came loose and I tightened it without checking.

    The collar was adjusted so the tip and not the shoulder of the drill bit was at the 3/4 mark.
    Waiting for the pic to download from my phone but it looks like yours, Jim

    Are you lining up the tip or the step to the mark when setting the drill collar? https://www.kregtool.com/webres/Image/Drill-Bit-Tip.jpg

    Here's my jig after making correction

    I'll go back out in a little to practice

    I know to align the step or shoulder.
    As mentioned above, somehow it was adjusted wrong
