<p>Jack,</p>
<p>Baltic Birch is generally plywood.</p>
<p>Is the baltic birch you're using, contain several plys?</p>
<p></p>
<p>Installing screws in the glued section, can easily result in the plys separating.</p>
<p>When the screw enters, between the plys, the screw forces the plys to separate.</p>
<p>A pilot hole is necessary, to avoid this problem.</p>
<p></p>
<p>Make the face frames from solid wood.</p>

<p>I would set the Kreg jig and bit collar normally and switch to #6 screws. They are somewhat hard to find but they stopped my splitting of dry cherry -- which was a nightmare for me until I switched #6. If you are working with face frames (mine are 1.5" wide) you only need one #6 screw in the middle of the frame as long as you also glue the joint.

<p></p>
<p>Just to let you know how bad my splitting problem was, my stiles would split even when I hand-tightened the Kreg screw vs. using a drill. Just as the joint closed as I slowly turned the screw driver the wood would split -- EVERY TIME! The second I switched to the #6 screws the problem went away and I have never has a split since.</p> I too am having a serious spl…tag:kregjig.ning.com,2014-03-19:2900167:Comment:6071372014-03-19T23:58:39.420ZJack Kellyhttps://kregjig.ning.com/profile/JackKelly

<p>OK, so I tried doing what I mentioned before, i.e. set the drill stop collar about 1/16" deeper than the 1/2" mark and use the 0.75" screws... with this setup i get a perfect join with no splitting almost 99% of the time!!! :D</p>

<p>I love my kregjig so much i honestly didn't consider just dropping it and using glue :) its much messier but i agree, if i can't get the splitting gone even with the 0.75" screws ill have to just glue it all together... i also considered trying the microjig? anyone can give feedback on that? are the pocket holes closer to the join or just smaller in size?</p>

<p>Wow, that is interesting. If you are making a top can you just edge glue the planks? You should not need screws for strength--the glue should suffice.</p>

<p>I assume you are using the standard #8 screws from Kreg. I would try #6 screw. When I have splitting problems (usually in cold, dry weather on hard wood) I switch to #6 screws and have no splitting. Not everyone carries #6. I get mine at Rockler and even they have limited selection.</p>

<p>I did an entire set of kitchen cabinets using Kreg along with several smaller projects. I never have splitting problems on softwood and have not had problems on hardwood in warm months (I live in Minnesota). During my winter kitchen project I was splitting cherry face frames about 50% of the time, even when used a screw driver to tighten the single #8 screw I was using on face frame joints. The second I switched to #6 sized screws all splitting disappeared. If you are using glue on your joints I see no problem using #6 vs. #8 Kreg screws.</p> Hi,

<p>Hi,</p>
<p>I am attempting to make counter-tops from olive wood and using pocket holes to put together the olive wood planks... the wood is 0.5" stock (17mm) which makes it much harder to get a good joint done... the wood itself is extremely hard and cracks super easy which is even worse...</p>
<p></p>
<p>I have followed the list above very closely which helped much to minimize the splitting but still i get cracks when the screws drive to the joined piece... i make sure to clamp real well, i have pre-tested with scrap piece to see where the screw comes out and aligned another piece next to it to see the screw reaches about 1/8" below surface... also i am using 1" fine thread screws and driving them into the material slowly and in pulses (in 2 out 1) and still i get splits as the screw reaches the hole end... i am also dipping the screws in olive oil in order to add lubrication...</p>
<p></p>
<p>i should mention that without these steps i would crack the pieces every single time... with them a lot less, but still do i get splits here and there...</p>
<p></p>
<p>i have also ordered the 0.75" fine thread screws in hopes this will help prevent the issue, but they don't get a hold in the material... they just spin in place as they reach the end of the hole... (should i try to reset the stop collar 1/16" deeper than the 1/2" mark? this may help the 0.75" screws get more bite?)</p>
<p></p>
<p>lastly, i have resorted (as mentioned) to making a small pre-drill with a hand dremel after the pieces a clamped which basically eliminates the splitting completely...</p>
<p></p>
<p>any advice is much much appreciated!!</p>
<p></p>
<p>thx</p>
