I think they would be harder to make than getting a bucketload of a fairly simple shape machined up. I cant think of any easy way to manufacture a box shape like that without welding. The round nozzles could be made on a nice automated lathe/mill type machine in a continous fashion from bar stock.

Your proposal is still subject to the other three loss mechanisms I pointed out. -p _______________________________________________ ERPS-list mailing list [EMAIL PROTECTED] http://lists.erps.org/mailman/listinfo/erps-list _______________________________________________ ERPS-list mailing list [EMAIL PROTECTED] http://lists.erps.org/mailman/listinfo/erps-list
