When I take drawings to the water jet guy for samples I get charged $30 for set up and a charge per piece. It doesn't matter to him if they prototype or sell able parts its still his time. It only makes sense to have several samples to cut and use the full sheet ( 2'x4'). So instead of taking him one model of bumper for a sample I wait until I have enough to fill a sheet. Once I have enough parts that work they will be made each in quantity on the same sheet. I can potentially have the sheets stacked as well for less set up charge. I will still incur a per pc. charge though. Thank you for your interest and patience.
