Sumpter 250's 2014 Summer Scratchbuild Challenge

[Sumpter250]

Just how big are HO scale lobster anyway?

The carapace length is measured from the rear of the eye socket to the rear of the carapace on a line parallel to the center line of the bodyshell . Currently that minimum length ( in the State of Maine ) is 3-1/4" ( The carapace, is the main body, and does not include the tail ) The maximum legal length is 5", so the overall length, tip of the tail to tips of the claws, would be between about 11"-13"...... or, in HO scale, .126"- 1.49" ( 1/8" - 3/32" approximately )
    The Carapace cannot be shorter than the opening in that "gage"

I hadn't done that research yet, so glad you asked, now I know just what size "holes" the Tulle needs to have, to adequately contain / retain an HO scale Lobster For me, at least, a lot of the fun of building models is "doing the research".
