bfta chrono help
I've been asked to build a new box for the harriers chrono. This travels with T.cook to the bfta gp's held across the country over the summer season.I'm making a wheel to rest the air reservoir on which will rotate to suit different barrel centers.It will look like a 6inch sprocket with offset 32mm dips in it.
I'd like your help in making a list of popular ft outfit barrel centers.I need a measurement from the bottom of the reservoir to the center of the barrel.
Thanks in advance simon.
