Hi Bill, thanks for checking in.
The engineering of this kit is well thought out. In these steps I'm referring to the molding marks and their visibility after assembly
The ejector pin marks have identical tooling marks which are actually in the manufacture's molds.
These mold seams are present in four locations on each side between the framework details of main bridge frame support - part E20
It's difficult to get a sanding stick or a file in there so I grabbed my no. 11 knife blade and scraped back and forth until this seam was gone
This is the only place that the ejector pin marks are visible. This area will not be easily visible once glued on top of part - E6. Putty and sanding these marks are the builder's option. I didn't do this on mine
These parts were built as subassemblies for easier handling purposes during sanding and installation.
The flat mounting parts - E23 E24 E25 E26 with handle parts - E14
The 'cleaned up' subassembly can be held with tweezers . . .
. . . then installed into final location
