Backwoods Baldwin (Lyn 2)
The chassis of my original 'Lyn' was built by
Peter Wallace, who reported that it was extremely difficult to get
right. The design is supposed to have compensated suspension. Sadly this
did not work well and the system was locked. The loco is still running
very well although the axle boxes are a bit worn now.
For the new 'Lyn' to be used on our Bratton
Fleming layout, I was determined to use a mechanism which allowed for
easy maintenance and had thought of using the new Lilliput chassis which
is due out soon. In the end, I elected to maintain the correct wheelbase
as it would have been very difficult to do otherwise with the etched bar
frames. I therefore decided to turn a Grafar class 08 chassis into the
motive power.
I always try to build my models without the
help of lathes and other fancy tools, which most modellers only dream
about. This project was no exception.
The Grafar chassis was reduced to the metal
block and with some 'cut and shut' technology we landed up with a 4
wheel chassis of the correct wheelbase.

The loco ran perfectly for several shows and
was then accidentally started flat out. From then on, the loco bucked
like a wild horse and no amount of attention ever got the thing to work
properly again!
Desperation grew until a search in my bit box
turned up a discarded Grafar diesel chassis which had almost the perfect
wheelbase.
Class 08 wheels dropped right in, both with
gears from the Grafar chassis fitted to them. New rods were
manufactured.
In no time the chassis was fitted into the
Backwoods frames. With both wheel sets driven, the chassis works
perfectly and all is well with the world again.
