As I said above I spent all day making one wheel pant. Tonight I put the assembly on the scale and it's 50 grams so two the them would be 100 grams or 3.5 ounces. This seems to heavy to me. So I will be building a different set of gear doors. I would like them in the one ounce a piece range. The spats will be of the same shape and size as the pants only doors.
