I just bought a Square-Cut jig and found that the smallest the adjustable arm would adjust to was about an inch which is to long for my Robi 5 1/2 battery operated saw.
I read where one fellow made a hard wood adjustable arm that solved this problem But after looking closely at the back I felt I could remove a small portion of the groove on the main body to allow the arm to be slid in and fit my saw.
After scoreing the part to be removed I used a flat hobby saw and removed enought to allow the arm to be slid further into the main body.
I also had to length the hold down slide goove using a drill press and a dremel tool.
after following the directions I now have a jig that can be used with all my saws.
I believe Kreg should modify the main body to allow the arm to slid in flush with the main body.
I had to do the same thing,the guide arm was too short by 3/4"-I use a 5/16" drill bit and an exacto knife to lengthen the groove.
My circular saw is a Milwaukee.
I am having trouble too, just bought it and I have a ryobi 18v cordless circular saw. The arm extends too far out and will not calibrate too my blade specifications. Anyone with this problem can give me a step by step guide on how you solved it?
Thanks so much
