I need to build some raised panel doors that will be painted so I want to use MDF for the panels. I am reading that most panel bits are sized for 5/8" thick material unless getting one with a back cutter then you can use 3/4" (same as rail and stiles).
I want to use as thin as possible to keep the weight down. I don't care about the recess in the back and want to keep the panel flush with the stiles and rails on the front.
Could I get by with 1/2" MDF?
What is confusing to me about 5/8" material is if there is a 1/4" groove in middle of stile/rail, that would leave 1/4" above the groove on the frame. Since the panel is flat on the back and is 5/8" thick, the groove takes 1/4 with 3/8 remaining, wouldn't it sit above the frame by 1/8"?
With 1/2" material and the panel routed to a 1/4" edge, I would think the outcome would be flush with the frame.
What am I missing? Maybe the groove on those sets is not centered?
Thanks for your input,
Todd
