Lp2 track pins

[Lynn Eades]

If any one cares to check it out for us, I have a drawing from Bovington dated 7-2-44.
The material is : M.C.I., B.S.S. 309.
As the track type is listed as "Cast: I would assume M.C.I. refers to maleable cast iron, and that the B.S.S 309 is the pin material?
As this is late war I think they have dropped all the fancy additives (manganese etc) and gone with the M.C.I.
The pin upper limit is ).437" and the lower limit 0.432" This lower limit would allow the use of 11 mm bar stock.
Just for interests sake, the distance between the hole centres (pitch)in a track link is 1.718" plus or minus 0.015"

I would heed Ben's warning, but also wondered what that guy used for pins?

More info: a track weighs 595 lbs, and the ground pressure is 8.8lbs per sq. in.

Dale: note this spec is for a British MkIIIw. Your LP2A will be close. The dimensions listed will be the same. Materials may differ slightly.
