I have to make and interior and exterior !x4 flat casing for a circletop window on an addition that I built for a customer. Andersen only seems to make a colonial interior casing. Anyone have any tips for cutting these. I’m thinking band saw with a jig set up to swing the radius thru the blade. Inside casing is stain grade so I would like to make it out of no more than 2 pieces, with one joint at 12 oclock. Any thoughts on how to set up the jig or others will be helpful.
Thanks,

Unlerss this is one monstersixed window, you wouldn't even need that joint. Flat stock is easy - buy a sheet of MDF and use a jigsaw

I've done this a bunch of times; there's a way that I really like, and another way thats fast.:)
The way I like is to use exterior MDF ( Medex ) and a router w/ a cutting bit and a jig that I made about 10 years ago. Swing the radius for the window ( I add about 1/8th to the actual radius ) then add desired width to radius and swing again.Make sure you anchor the piece down so when you finish up your cut, it doesn't move on ya.This method may be overkill on exterior trim, but I like it, and if you're doing a bunch of pieces, it actually ends up being fairly quick.
The faster way is to cut 2 pieces (or more, depending on the size of the window), of 1x12 primed cedar, cut angles to create a rough half circle, glue up w/ gorrilla glue, use a piece of scrap to swing radius, add width desired to scrap, swing 2nd radius, cut w/ jigsaw.Belt sand to clean up. Adequate for outside; not my favorite.
My millwork supplier carries a flexible flat stock, paintable, for interior work.
FWIW.....Bing
Actually, fastest is piffins way w/ MDF and jigsaw...B

dog... for your exterior you can also use sections of 1x12 Azek , rough cut ... welded together ..
then swing your router

Swing the arch with a router, shouldn't take you more than a few minutes. I actually think I can do it quicker than someone with a jig saw.
Plus the cut is a damn site nicer.
