no tech, I'm waiting for my trusty [but inexpensive, ie: slow

] bodyman to finish the tin bashing and turn the thing right side up so I can put the cross sills back in and fiddle w/ the wood - I will relay the whole layout once I get it together, and your calc setup looks like it'll work for the fleet
BTW, I still get the 'file is damaged' error trying to check the fleetGMbed_kits.pdf
