  1. That has been suggested before but the indexing wheel that I acquired at the same time had no chance of fitting and even if it had I can't see how it would work.
  2. This strange instrument was found amongst the workshop I purchased from a retired engineer/modelmaker some years ago and it has confounded far more experienced brains than mine. I also acquired at the same time a large collection of ME mags going back to the 1950s and searching them has not yielded anything. It fits the lathe bed of my Myford 7 and has a toggled centre pin enabling maybe a disc shaped workpiece to be mounted under the swivelling pointer arm. There aren't any graduation markings visible. Someone out there must have an idea!
  3. OK I've come to this one nearly 2 years late, but had to report that that's me driving the Croc at Tan y Bwlch and I was involved in the construction of the beast. It was indeed the brainchild of Brian Hollingsworth who built the body. The bogies were the work of Don Fifer (Pfeifferbahn), the beautifully metal bashed and distinctive bonnets were by Warren Shephard (7mm modeller of note these days) and I was charged (!) with the electrics. As I recall each bogie had a 1hp (I think) 36v motor controlled by a commercial chopper style control box amidships with the lead acid batteries. All conrol was from a cable connected hand held box which controlled air brakes, air whistle, forward/reverse and power controller- all of which presented quite a challenge design wise as it had to fail safe in the event of the controller being disabled.. The piece de resistance were the RhB station bell sounds recorded to a ROM chip (in 1987 !) and donated by a Swiss gentleman I believe and this necessitated the Croc to have its own sound system! The intention was to have the battery charging done by way of the pantograph (which Brian lovingly crafted mainly from Meccano) from catenary contained within its shed which Brian had speciallly made and was installed on its own siding alongside the Cafe but this was never finalised. The railway itself ran for several seasons and all the equipment was Brians and later returned to his home to enable completion of his Croesor Junction and Pacific Railway. Other locos of Brians that ran there were :-The EAR Garratt "Mount Kilimanjaro" lately with its sister at Weston Park, "The Queen of Clorado" ( D&RG K27 2-8-2), The Darj- Darjeeling B class and briefly "White Fire", a Bullock Pacific ( Originally "Monarch", then "Audrey" and when Brian aquired it, "Bubbles"- he gave me one of the plates!) regauged from and now back to 10.25" at Eastleigh. Happy days pre H&S police and Safety Cases!! Nobody got run over, burnt or electrocuted.
  4. Well this is the true nature of modelling- after we start something we can always find a better way and it's knowing when to stop getting better ideas and actually produce something so unless I can be convinced that my Black 5 chassis is a treasure worth a lot of money I'm carrying on! After all ageing eyesight is making 7mm look attractive so anyone fancy a GT3 kit in 0 gauge?
  5. I am a recent purchaser of John's GT3 transfers and jolly good they are too and am a long way down the road of GT3 construction using the Hornby Black 5 chassis, life being too short to go the etched chassis route -after all I am old enough to have seen the beast crossing the "13 Arches" Leam Viaduct south of Rugby, which I just happen to have modelled -hence my interest. Now here's the rub -that lovely etch of Ian Macdonald's - are you doing anymore Ian? or anyone have one?!!!!! Trevor

  7. I've clearly come to this very late in the day but the following could be useful even if it means waiting till next Christmas. Wilkinsons Stores (others are no doubt available) did a range of mains and/or battery powered Christmas lights which were LEDs in a warm white colour which are eminently suitable to represent incandescent bulbs. Cannibalised they cost less than 10p per LED, are 3mm nominal diameter and run at as little as 1ma produce a very lifelike result. In buildings 3 connected in series (their forward voltage drop is around 2.5V) with a 4k7 resistor (tiny -1/8th watt will do) fed from 12v DC work fine, or for a single one in a signal box use 8k2 or 10k for a realistic warm glow. The package is not the conventional domed LED format but cylindrical and amenable to being turned by spinning in the minidrill chuck against a coarse enery paper - I've succeded in replacing the bracket lamps on the side of the Bachmann GC station buildings although wiring is a bit hairy -literally as with such low currents it is possible to use very fine enamelled copper wire 48swg, or even smaller! Oh and a note about polarity, all LEDs have the cathode (negative end) as the larger internal electrode although you may need a magnifying glass to see it. Hoping to inspire.

  8. I know I've probably come to this a bit late in the day but you really would have made life easier for yourself with the original TIP147 (CPC,Maplin, Farnell etc) idea -it's a third of the price, more than man-for-the-job and all insulated so could be mounted straight on the box using a metal bolt and a little heatsink compound (or even vaseline), making sure the mounting hole is adequately deburred.
