Thnx, good addition I already had a problem with the connection of the USB cable to the mem card as the mem card socket was not formed properly and had to be re-shaped a little - I suppose the constant vibrations could loosen a lot of things.

As an additional note, I tied down the machine to a separate bench top I made with light cargo straps and a solid plywood top on spacers to transfer some of the vibrations to the bench top and that seemed to help a lot but had to be careful so as to not throw the machine out of alignment. Also have not yet found cargo straps that are fine toothed enough so had to adjust eye bolt tie downs to the bench top to get what appears to be the right tension
