All,
I need to make several large doors, greater than 17″ wide, so I would like to have a style in the middle of the door for stability and to reduce the possibility of warping.
I am most concerned about getting the panels sized correctly. I use Freud bits which came w/ a formula for making 5 piece doors but not 7 piece ones.
What is the easiest method of doing this correctly, the first time?
Thanks,
dlb

Just treat the center stile like horizontal rails, bead and groove on the sides, cope and tongue on the ends. I always cut my copes first, that way, if you get a little blowout the bead cuts will remove it. Dry assemble the frame and measure for your panels, allowing some expansion room appropriate for the panel size. Although the panels won't expand much end to end, the rails may. If you don't allow the same space on the ends as you do on the sides, the 45 corners won't be in line with the corners of the frame. You can use spaceballs or short pieces of plastic tubing in the groove to raise the panel in the frame so the corners align, that's if you are fussy and notice such things.
Warping has a lot more to do with your stock selection and if your milling procedure ensured that the stock is straight and flat. It often helps during glue up to clamp down to a flat surface so you don't inadvertantly glue up with a twist.
Thanks for the reply. I was looking more for a formula to determine how big to make the panels. Well, as it turns out, I just milled a center stile, put it into position, took a few measurements and out popped a perfect panel! Imagine that!!
On a serious note, I believe that there is a formula based upon width of door, width of stiles, location of center stile an
'+7/8 - 1/16' (Freud) that wil produce double paneled raised panel doors.
Thanks again,
dlb
