Required accuracy / resolution of truck scales?

The info is not on the website, but I did get them to have the "district guy" call me back. Turns out it varies with the scale capacity. The thing is, the two scales could be off in opposite directions, so if I understood him right, for these particular scales, a total "on the order of" 80 lbs difference.

Of course you could cut that down to "within 40" by weighing the same load on both scales

One reason I'm interested is that a guy back east is interested in a little lathe I've got, "SIP"



This thing weighs somewhere between 150--250 lbs. The plan is to get the bed of the lathe onto a pallet in my pickup, and assemble the rest of it onto the bed. Then construct a surround box out of 2x2 and 1/4" plywood. I need some sort of weight to ship it.

I actually have some friends at a local plumbing supply that will ship it, but I need a way to weigh it
