Well the bench is set up enough in our new house in Maine to start a project based on a MACK DM800. Started by adding a scale 4'-6" the reissue DM 800 front chassis to a) move the front axle forward 2' 6" and b) move the engine forward 2'. Shorten the center of the chassis to give me a 174 inch wheel base. Than from the center of the bogie to the tail end I cut off an additional 1' 4" to set the rear chassis length. Hit to parts box for pieces to make up the 6 cylinder Maxidyne and a Triplex transmission. Front motor mount is combined from the DM800 and the DM600, rear mounts are combined from the DM600 and the R685ST kit. Did my normal front axle modification of cutting off both the axle ends 1/4" in from the end and than removing 3/16" from the main axle. Re align and glue up and last add a .010 x .020 piece of plastic in the back for additional support. Shorten the tie rod the same amount. Paul

Got a bit more done. Moved the front axle assembly forward a bit more for aesthetics mainly. Got the right fender set up less the air filer and exhaust piping. The radiator and fender is temporarily mounted as a reference base to locate the firewall and cab off of. Cab is got the basic shape and pivot hinges are made up and work pretty smoothly. Paul.
