I’ve finished my bench ( glad I did it) and now I am back to making boxes.
I have made several boxes with box or finger joints using an Incra I-Box jig on my Grizzly table saw. I started using 1” poplar and once I had gotten most of the major mistakes out of the way, I stepped up to clear, straight grain 1” Hemlock. I considered these practice pieces getting ready for something a little nicer. Not show quality but I was happy with what I learned and how I progressed through the several ‘test’ boxes I finished.
I have just started my next box project using 1/2” quarter sawn white oak and I’m having an unanticipated problem: I am getting serious ‘reverse’ tear out with the I box jig. By that I mean the cut joints are leaving ragged edges, something I didn’t experience previously. The only thing which has changed is that I am now using thinner stock (1/2” vs 1”) and it is quarter sawn oak. these joints are made on the end grain of the stock. Any idea why I am having this problem? Do you think it is the fact that the wood I am now using is quarter sawn?
My dado set is not the greatest but it cut fine previously, and I have taken pains to set the jig up according to the instructions that came with it. I know I could probably back up the stock with a sacrificial piece and will do so if that is the last resort but hope some one out there knows a better way to solve this problem. I would attach a picture but my camera’s resolution is too high.
I will charge up the battery on my old camera and see if I can get a pic with it that will work here. In the meantime, who’s got the easy button on this problem?
