Staple in the big toe... OUCH!!! I think I would have been crying at that point!!
After this little set back of forgetting the fancy hand holds, I decided to start doing what I seen Don (The Fat Bee Man) on you tube do. When I've got the dado stack mounted in the saw for doing the rabbets on the end board, I'll just cut a 6" long, by 7/8" wide, by 1/2" deep groove into each side. I tried it on some scrap and found that I gave a good purchase even with leather gloves on. A lot faster than setting up and making the "D" grips with a jig and circular saw. I thought about adding cleats but I like the cleaner look of the hive without them. May change my mind at some point... never know! LOL
