Good progress on the M7 mods, the 32g of mazak ballast in the side tanks - most of it behind the rear coupled axle centre - gone; and now just coming up to 40g added, all of it forward of the same axle centre.As an 0-4-0 it's nearly balanced in the middle of the coupled wheelbase now, and there's some small fiddling pieces of lead to go in well forward yet, and if I can find a brass or whitemetal chimney to match the pretty fine Hornby piece, that will go on as well.
I have rewired the loco too, partly to eliminate use of the chassis block in the current path, but primarily to completely declutter the front of the model for more weight by routing the driving wheel pick up wires to the rear; the hardwired decoder will be at the rear of one of the side tank voids.
The bogie will be arranged to simply trail around, not supporting the rear of the loco at all, so no lifting weight off the drive wheels which significantly reduces the traction of the model as supplied. I am searching for a couple of split axle 10 spoke circa 14.3mm diameter, so that the bogie can be modified to collect current with no wiper drag; I know I had some off worn out Bachmann split chassis locos, now where did I stash them....
