Started putting together my first bottom end together today
Put the rings on the pistons, then attached the rod with the gudeon pin and locked that in with the circlips. Then i put the acl bearings in the mains, put the crank in on top, then the girdle after that. Then it was just a matter of putting the piston/rods in the block and attaching the big ends to the crank.
Heres a few pics
