Patience Spamicus ...... patience.
There, that just about takes care of the whole lesson in DML Sherman tracks.
Do lots of measuring, I have found that building them in sections is this best thing to do with them. Top run, bottom run, curve around the idler, curve around the drive sprocket and then two short runs to make up the differences.
They are definitely tedious, but I do like the end result.
What Canadian unit you doing with your Sherman?
Don't forget the pics !!!!
Happy Modelling and God Bless
