Finished product handsome and useful.  Directions should have been clearer on difference of assembly of articulating arms (only the right needed both knobbed bolts, and the "v" slot that was to contain the knobbed bolt on the side panel required a great deal of filing before the nut could be attached to the bolt and there was never enough bolt poking through to accept the nut and the lock washer, so only the nut was able to be fitted.
Bad engineering that the assembler had to cope with; resulting in only 4 vice 5 stars in rating.
