Actually....I do have a pocket gage I invented that when placed in the corner pockets and lined up in the feather strip Dado it point blank shows you where the sub rails need to end and the miter angles as well for any size pocket I want.... symmetrically centered. Diamond has copied it and made 3 pocket gages of their own as to be able to check their own work.....after they got a suprise using mine....but I'm not selling it:thumbup:
