First project of the year. Face frames for 2 cabinets I'm building. My very first cabinet last year came out perfect, this year not so good. I'm using 1x2 Poplar and course screws. The styles split when the screw went in. The only thing I'm doing different is using a new Makita Impact driver I got. Last year I used the drill/driver and had no spliting. Did I over drive the screws or did I just get a different quality of wood. I'm assuming Poplar is a soft wood so the course screws. Was that wrong? What did I do....?

Hi Steve - I would guess the impact driver is more than a tad robust. I admit I use one on occasion but I'm generally in a construction mode joining 2x4's. On 1x  stuff I use the cordless with a clutch setting around 12-15 out of 28. Coarse screws are OK for poplar, that's what we used at the furniture factory I worked at.
Loose the impact driver; use a drill/driver, with an adjustable clutch setting.
Thanks guys. That's kinda what I was thinking. I even did a test piece first and it split, but I went ahead and used it anyway. Duh... What kind of logic is that, huh? :-)

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…
