I am learning from others that my method is the old and not so fast method. However a 6 in square (see-through ruler) with a diagonal line helps me to square my block to the proper dimensions. Sometimes I am :right onthe money" and other things I need to square. Rotary cutters were made for squaring and trimming so everything is neat and clean and perfect.
I am still going to wait and weigh-in on what others tell me about those thangles. Just what I read does not convince me so far. Sorry!!!
Tried and true methods work best for me.
Keep trying.....someone may convince me yet. I am open to learning.
