Thank you!! I just bought mine on Amazon, its the 12" long one...but I liked it so much I ordered another one that is wider (8") same brand...Ill post on them on another thread once I use them a couple times!
My idea is to glue a thin board as a stop (a paint stir stick would work) vertically and horizonally, if glue dont hold I will put some small screws in. The cuts arent perfect but I think they are just fine
