A little hint to help out. Get all the screws started before tightening them, It will be easier to put the last ones in if there is some wiggle room.
The directions were to put it together to this point without tightening so all of them are screwed in but loosely. All of them have to be tightened except for that single one I finally got tight. I think I’m stripping the Phillips head on the two screwdrivers I have inside and need to get a Craftsman Phillips out of storage room tomorrow.
