@ Robin yes, that's the plan. I have a Metalsmiths O gauge GWR TT, all finished on top, but not motorised - I'd like to set up something that would allow me to push a button and it aligns with either a preselected track, or the next track - haven't quite sorted that in my mind yet. The other attraction is that Arduinos will drive 6 servo motors - which cost something like half of a Tortoise point motor and also allow for the "prototypical bounce" if used for signals. So I see the Arduino as a useful bit of kit,. and one that I would like to learn more about And then, as you say, you can convert a lathe or milling mc to NC control... could add to the modelmaking arsenal too. I'll keep you posted with progress! SD

Robin Thanks for the challenge.... But I think it is beyond me at the moment. I'm trying to sort out a stepper drive for the turntable I built in 2010, and finish two locos that I started in 2006 (ok, lived abroad for 3 years, but we've been home nearly 4 and they're still not done) and there are n other unfinished and unloved projects to do... And that's not even considering my competence, or lack thereof! SD

Love the sanding jig 11/10 for lateral (or should that be axial?) thinking!!! SD

Radio control sounds wonderful, except for the sounds..... I just upgraded from DCC to DCC + Sound and I love it - and now you are showing me 009 loos driving silently on glass... My initial attempts at "stay alive" capacitors seem somehow like wasted effort! But I can't imagine not having onboard sound (ok, O gauge here, sorry) - I was planning on upgrading the fleet - which will cost the thick end of £100 per loco and there are 2 done and 9 to do, plus at least 3 to build, but the entirely glitch free running is gorgeous, so what should I do??? I'm well impressed, if you hadn't noticed SD
