# "two panels" calculation ...

• posted on May 24, 2005, 8:04 pm

In raised panels, I understand the calculation for "one-panel" assemply. Need help with "two-panels" assemply (the width).
- = subtraction + = addition x = multiplication / = division
************************************************** total assemply width - (3 x full stile width) + (4 x panel groove depth) - (2 x panel width expansion allowance) / 2 **************************************************

I'm not sure what your question is, but here's how you compute panel width:
t: Total assembly width s: Stile width g: Groove depth p: panel width e: expansion allowance
t = 3s + 2p + 4e - 4g solve for p: 2p = t - 3s - 4e + 4g p = (t - 3s - 4e + 4g) / 2

and don't forget the gap between the doors of about 1/16 to 1/8, depending on how tightly you want the doors to come together. You'd have to SUBTRACT a bit from the rails and the panels.
I PRESUME by two panels, you mean two doors that open together in the middle, right??

No, "two panels" assembly meaning one door with two panels. Unless there's another name for it, that's how it is called?

Just like a single panel, dry fit the rails and stiles and measure the openings. Add 1/2" total to the width and height of those openings to determine how large the raised panel should be.
