RE: building board
Not really, thanks btw, I drew up some rough basic ideas and just started building, and loosely based it off some bench plans Ifound on the Internet. Iwanted things at justthe righthight, a bench tootall or too short sucks. It does make a difference. My machineshop bench that my Lathe, mill and drill press are on is higher, which is perfect for those operations.I'd build itto your specifications, and the second shelf was highted just enough for my scroll saw and a mid-section three drawer tool box on the other side.
Icould probably dig up what Ihad on it, and you are more than welcome to have. Let me see if Ican still find that stuff.
it is mosly just 2X4, with the thickest subfloor top 5/8 or 3/4 I don't remember, with a galvinzed steel top, and all screwed together.
I still had to shim it lenth-wise and reshim it agian before it became stable with a runout of 1-2mm runout across entire72 inches. Ididn't have too much trouble with it width-wise or diagonally.
