I received my GA5-1R on Thursday February 6, 2014, today Friday open it up and put the table together and set up the servo and the machine. The presser foot lift is 3/4". I sewed through 4 layers of 8-9 oz. veg/tanned leather with no problem right out of the box, did not see any marks on top or bottom so far. Played with the stitch length seemed to work ok, the reverse worked fine also. I was sewing 277 bonded nylon on top and 138 on bottom. I'm looking forward to sewing on it, my PFAFF 1245 will be my back up machine now.
I welcome any and all comments, I do not post very often but I do read and learn from Leather workers network.
