F72
Chassis Re-Build
In May 2010
the Bachmann chassis of F72 finally gave up the ghost after a
running life of ups & downs of reliability. It was decided to
have ago at building our own chassis, this is a first for the AFR
so the methods used could be totally different & quite basic
as I have used bits from scraped locos & materials that I have
obtained from different sourses ;-)
Above Left;
the chassis is constructed out of 32mmX30mm aluminium door
channel. Above Middle; all the axle holes, power pick-up
holes etc have been drilled & the bottom runners (the curve
pieces) have been cut off. 4mmX4mm spacers hve been added these
were drilled & tapped with machine screws with the heads filed
off. Above Right; a clear view of the underside with
spacers in place.
Above Left;
close up of the crank pin, these had to be added as the wheels
were only spoked with-out crank pins. This was done by filing a
slot in the pin & slipping over the spoke with a collar to
hold in place while the glue set. Above Middle; motor
& wiring are all in place. Above Right; under-neath
shot showing the bachmann pick-ups in place, the bearings used are
nylon so will be interesting to see how the wear!
Above;
F72 on its test run after major work on her chassis, I am very
pleased with the result as this is my first attempt at chassis
work, but time will tell!!
