Richard, I like the way your tray inserts are shallower than the actual sides of your drawers.  The biggest problem I have with those shallow drawers in the Festoy storage boxes is that it is so easy to not judge the extent the drawers fcan be loaded.  If a tool does not fit perfectly, it becomes a very annoying process to get the drawer opened. It never seems to be the same prceedure as before to get a drawer opened.  you have made the allowances that one does not run into such problems. 

Great job, as with all of your solutions.

@Richard/RMW, Yeah, I'm fine.  I just picked up a HKC w/2 batteries and charger. (I had one corner of my shop that had a tiny unused space) Haven't used it yet as grass seeding time closed in on me.  I'm not sure yet how it will handle for me. I have a bit of carple tunnel and two fingers and thumb on left hand are very numb.  you should see me at the table and trying to handle fork or spoon.  It gets to be quite an adventure.  The Boss gets all worried, but I just laugh and tell her I will learn to use my right hand wrong.  Of course, I could always move to Oz where everything is upside down anyhow. Or I'll maybe figure out how to use my elbow somehow. I had a cousin who could pack his pipe and light it using his toes. Oh well. aside from all the other aches and pains, i still have fun and still enjoy working.  Went to D.C at Easter.  The Boss and I were having our 51st and our good friends were having their 15th.  We were calling it our 5115th aniversary.  Dam, how time flies.
