Re: Garratt conversion

?I had to dismantle one engine of my NGG16 to deal with a loose wheel (yes, it can happen with Romfords), and the resultant damage to the flycranks.?
This is not an easy job, as the kit underframe is designed to fold up around the assembled wheelsets, and once that is done the wheelsets cannot be removed.?
I ended up making some new frame crossmembers to the exact dimensions between the frames of the engine as assembled, cutting apart the existing end frames and ?crossmembers to separate the side frames, then rebuilding ?the whole underframe assembly around the replacement wheelsets using the new crossmembers. Very much to my surprise it worked - but my heart was in my mouth throughout!
And many, many thanks to the 7mmNGA/O14 group member in Australia who supplied the replacement flycranks - sorry I’ve mislaid your name!

If its built using the supplied wheels they’re Romford so on shouldered axles so, no pushing them in won’t work. I think you’d end up dismantling the lot

Subject: [o14] Garratt conversion

?

Hi all
I have been offered the possibility of acquiring an NGG16. It is a fully built Backwoods kit, modified with different motors and gears (not yet sure what) but built, as far as I know, as a generic Garratt, rather than a specific engine. Big question, how easy would this be to regauge to 14mm? Would both entire chassis need dismantling, valve gear and all or is there a way of pushing the wheels in on the axles without disturbing all the frames and gear??
Cheers all
Paul?
