Morfa - Victory from the jaws of defeat.
This last couple of weeks hasn't been very productive on the model making front. A cold, kitchen refurbishment and clearing up after puss' random acts of crapping have put a crimp on time and energy. However, Thursday evening looked like a good time to indulge in some railway play.
Time for a treat I thought; I'll see about a quick and simple EM conversion of the Limby 101, that lay untouched in its box for the last seven years or so. Half an hour later the wheels on the power car had been levered out to the right width. Plonk on track, turn up the juice; what a god awful racket. I'd not noticed how huge the flanges were, it didn't just hit the chairs as it thudded along I'd swear it clouted each and every sleeper too. Ok, lets jam some other wheels on the axle. Problem; axles fatter than standard and by the time I'd reamed out the insulating bush on a wheel I'd borrowed from my 103 there was no insulation left. Time to try another tack. This time I chucked one wheel on its axle in the collet of my pendant drill, and tickled the flange with a file. Flangeless DMU wheel anyone? So the score on Thursday was two DMUs broken in one evening.
This morning I thought I'd see if I could salvage something. The previously mentioned 103, has been something of a problem child ever since I started building it. In a moment of bravado I decided to build a motor bogie for it. It had similarities to the old Triang diesel bogies with a Mashima motor placed longitudinally between the axles and driving through a pair of Tenshodo spud gears. Initially it kept locking up and try as I might I couldn't adjust it to run smoothly, so I took one set of gears out which improved matters. It could just about manage to haul itself out of
Abergwynant's fiddle yard and into the platform (a straight run of 18") but when I showed it Morfa and curves it just turned its toes up. It went back into its box and pretty much stayed there till I robbed it of a wheel.
I began to wonder yesterday evening about rebuilding the motor bogie, but I thought I'd have one last go at tweaking. The first stage was to swipe another insulating bush from a spare donor wheel to replace the one I'd reamed away. I also took out some of the sideplay in the axle furthest away from the motor support with a washer. Both axles were knurled in the centre to get a better grip on the worm by pressing and rolling with a file. After taking out the slop in the axle I added some to the gear meshing shifting the motor up a fraction in its mount. I was utterly gobsmacked when I put it on the track to test. Recalcitrant b@st@rd to complient angel in half an hour.
The upshot is that I've had the smirk of self satisfaction plastered on my face ever since. Partly because the challenge has been overcome, but mainly because Morfa just looks so right with a unit trundling round.
