Today I had to fix a problem left me by the contractor that did the rehab of our garage. In order to cover the foundation on the inside, furring strips had to be added so that the wall would be a single plane rather than jutting out at the foundation.
When I went to install the jamb extensions I had made, I discovered that the "carpenters" had not lined up the furring strips that framed the windows with the opening.
As a result, the jamb extension would not line up with the jamb. Routing a rabbet that was 1 1/4" wide and went from 0" to 1/4" in depth, wasnt an option, so I had to cut back the furring strip and the wall board.
I could use one of my long tracks and the SSRK, but a router would really have made a mess, and there might be unseen drywall screws. Attaching a track to the wall and using the circular saw on the track just didnt appeal to me. What I did was attach a long (84") SME to the wall above and below the window opening using a neat litter fastener that I had made for another purpose. This would act as a guide for the side of the saw base.
The fastener is just a block of UHMW with T-Nut and screw fastening it to the side slot of the SME, and a long screw fastening it to the wall. Could have used a long piece of straight wood instead of the SME, but finding straight wood can be a fun exercise.
I very carefully plunged the saw and made the cut.
Worked like a champ. Had to also do the left side and top of the other window opening.
Oh, there were a few drywall screws.
That would have played havoc with a router bit. The carbide saw blade just went right through (but I guess I have better replace it one of these days).
Ill add pictures of the completed windows once Im done.
