Double Fairley

[Ian Holmes]

Hi Guys,
           It's me again, does anyone have any ideas about re-wheeling a Bachmann GP50 for the Langley Double Fairley? I have seen a video on You Tube but unsure as to how it was done, but it looked good. There are several problems with the motion so my Idea is to re-wheel with something a little larger and use a mixture of some original parts and some of RT'S excellent components. Any help or advice would be most welcome, I am not going to confine it to the "One Day Shelf"
Thanks Again
