Some recent activity with the first engine unit - I (1) removed the cross braces (the Bullant can be ordered without them) as they would have fouled the frames. Then (2) drilled through the second driver (that the coupling and driving rod will be fitted to) and fitted Alan Gibson crankpins to test clearance. I then (3) measured out and made the frames from the thickest styrene that would fit as they will be load-bearing. The frames were painted and weathered black/brown before attaching as they will be very hard to get to later. Also (4,5) made the leading and trailing bogies from styrene. The wheels in the bogies are Steam Era, with the pinpoint axles cut off and filed down flat as the 12 Class had inside bearings.
