Dealing with Oversized Extension Jambs
I have a situation where I have new Pella windows with 6 9/16 jambs and applied extensions. The problem is they are about an inch too deep. What is the best way to address the situation now that they are here and oversized? Should I attempt to remove and rip down the extensions? They appear to have been tacked on from the side with crown staples in a space let in to the side for this purpose (as opposed to the shorter extensions I have seen which are stapled through the front).
Thanks, Brian

Brian,
How many windows are you talking about? I've always ordered windows 4 9/16" (standard size) and make my own extensions after installation. It's usually cheaper to do it that way if you have access to a table saw.
Either way, they probably need to come off unless you are real skilled with a some kind of a power saw and belt sander.

WSJ,
I have a dozen windows to do. The Pella rep at Lowes recommended ordering extension jambs oversized and then adding as necessary to the outside, as I had to close in the framing a bit to conform to their standard sizes. Seemed logical at the time, until I saw how far they would stick out. The Pella rep I asked after I got them said that I needed to flush the nailing fins with the sheathing, rather than framing them out so they would be flush on the interior, and recommended pulling them off and cutting them to size. I was trying to save finish work, and ended up with extra.
So, pull them off, rip them down, and reapply them?
Thanks, Brian
You're going to have to pull them off and rip them down. Table saw is th only way to go. I don't know if they are glued on or not, but if they are you may have a problem. Getting the staples out of the piece is going to be the hardest part if there is no glue.
I've never heard of anyone building out a window between the nailing fin, and sheathing. I'm sure there is some sort of up charge for the factory applied extension jambs. Another example of the "experts" from chain stores.
So, pull them off, rip them down, and reapply them?"
Brian,
I'd try that one one, but have a feeling that they may be hard to get off without damage (plan A). If that doesn't work, I'd try to find a way to cut them down on the window (plan B) or make new ones (plan C).

Plan C would be a template and straight bit in a router with a guide colar.
Plan D would be the plung router and 3/4" motising bit and an edge guide. Take the excess off in 1/4" steps. Hope like hell there are no stable that high.
