Wayne,
For most of the assembly I used plain old Testor’s tube glue. I used CA to glue the valve spring retainers to the valves. You want to be real careful getting the crankshaft straight, i.e. as little runout as possible. My crank pulley wobbles a little.If you run it a lot the pistons start to scuff up the cylinder walls. You might want to consider some type of clear lube. I’m not sure what a person would use that wouldn’t attack the plastic or look smeery.
I am having a lot of fun building. Since the Hemi I have completed a Sherman, a 6X6 deuce and a half, and a Stuart Tank. I am currently working on a Tiger and have about 15 kits in my stash.
