The bane of this project is going to be: 1st missing parts and 2cd over sized and or missing details. The sub assemblies came together really quick but checking referenced there are a LOT of details that are missing, oversize and or molded in poorly. The tracks in particular are bad. I think that I am going to detail them with plastic card "rivets" made with a 1mm punch and maybe shave them down some to show some wear. I am missing a lot of the ripper bits and pieces and could make them again but I am going to put a simple draw bar on instead. stretched sprue and wire will make the hydraulic lines and then some odds and ends from plastic card. I have already thinned down the nose plate with a dremel tool (drum sander) on the back side of the kit part. the dozer had the grill on a DECAL sheet which is not only lame but missing. I have spent the last week looking for K&S brass mesh with round holes (1mm) but even online it is made of unobtainium apparently. In the mean time I am punching individual holes in thin plastic card to make another grill, the problem is I only have to screw up once to ruin that part and start over. But the punching can go to detailing the tracks. The goal of this build is completion though right? and it will be a welcome break to paint and weather something not military. It strikes me that we need a kit manufacture to step up and make some good construction machinery kits that do not date from the 1970s. maybe in scales around 1.20.3, 1/22, 1/24, 1/29, 1/32 and 1/35 which are common large scale model train scales for a broader market.
