let me start,by asking a few questions,and hopefully i can help.
what king of vehicle do you use for delivery?
is this loc.inside the flea market?
can you leave machines,if you could secure them/?
simply put .i would mount machine,and screw them to a piece of plywood or laminate
and mount folding legs to the bottom,or a folding table,with legs already attached
you would need a furniture dolley,they cost about $10.00 at Harbor frieght.
get back to me and i will try to help.
I am getting a location at an indoor flea market,but i will mount all machines to a formica table,and just put a tarp over it,with a lock
It should be fine and most other vendors use a similiar method good luck ron
