Overall we had a good show at Chatham last weekend. Plenty of room and appropriately we were sited under a real gantry crane. The aisles were very wide which meant unloading from our vehicles was easy.
We set up late Friday morning, did a running test in the afternoon and found the Bedford TK had melted the steering servo! Luckily we had a spare back at home and could replace the duff servo that evening.
Saturday started off with the crane hook playing up, luckily this was easily resolved by slackening off the pulley pivot bolt a touch, it was fine the rest of the weekend. Saturday afternoon the Morris had a rear wheel come loose on the axle leaving it with one wheel drive, unfortunately that meant it could not get round the slight gradient left hand end curve. Easily rectified that evening with a small dab of epoxy resin, I think I used superglue before.
Oddly as each day progressed the sound equipped narrow gauge locos started to fail. They behaved like they were losing power, but when pushed the sound would restart then the loco would fail again. They are identical SoundTraxx Tsunami chips with same make stay-alive's in two of them the third is all Bachmann sound chip with no keep alive. Two have eight wheel pick-up. I checked all pick-ups and they were fine.
If they were taken off the track for about 15 mins, they would be fine for a while then fail again. However if I was able to get them back running and turn the sound off they ran fine.
It seems like the sound part is overloading things, unfortunately the sound auto starts on first track power up. I think I may have found a CV ref on the SoundTraxx website that can disable the auto sound start, but have yet to test it out.
If that fails I will take out the sound chips, although at home they sound great, at a show you can hardly hear them, so is there any point in having sound installed?
We have a small list of tweaks we would like to do before the next outing, but we are getting very picky now.
Two shows left this year, Rapido Railex at Maidstone in September and the National Festival of Railway Modelling at the NEC in November.
