No close up needed. All you have to do is take 1'x1'X1/8" hollow square tube the height that you want the rack and weld a piece a of 2 1/2"x 1/8" flat bar to that , on the front corners weld two pieces on to make the corners. Put the weld on the inside so it looks good & smooth on the outside. I used white ash lumber, 1/4" carriage bolts and self locking nuts. Keep the bolts about 1" from the end of your wood slates. I use a mixture of 50/50 % turpintine& linseed oil on the wood and be sure to paint the metal.
