Re: Track Construction for a Test Track

Terry/Phillip, I'm not concerned and appreciate your modesty ... still very much enjoying learning. But it is amazing how every time you feel understanding is dawning a whole other level pops up and blows a raspberry at you. Its all a bit like peeling an onion. I have admired Minories ever since I ...

Re: Securing supplies of track components

I wish Phil well, he definitely needs to get on top of his IT issues and move to a prepaid , in stock only order process, this removes following up orders, cheques ( a time waster) and getting wrong amounts, back order etc , all a huge waste of time However, given the society supplies components to ...

Re: Engineering, Injuneering and Knitting

a thing I have always been curious about chez Rice is to do with suspension. Iain suggests (I think in his track work book but could be the chassis one) that on the real thing the track itself sinks in to the ballast as the train rolls over providing a degree of 'suspension'. This as I recall went ...

Scalefour news 204 -mailbag , cameo layouts

Bob Essery, as you would expect, makes a plea for prototype practice at exhibitions, bemoaning the compromises that tend to make models differ from the prototype. ( "Cameo layouts" , mailbag , Scalefour news 204 ) I don't agree with his premise that exhibition layouts should be some form o...

Re: Maximising Adhesion using Electronics

A possibly new thought is the use of clever control electronics to maximise the use of available wheel/rail adhesion. I'm not aware of any attempts to do this (perhaps I should check on MERG). Most clever electronics has focussed on running motors as slowly as possible without stalling. A maximum t...

Re: Glenmutchkin - Control Freak

Whilst it is a question of each to its own, I steered away from a CBUS system as I felt that if I did not understand truly how it worked and needed to make it (only the MERG system was around when I made this decision) then I was going to get myself in trouble! I see DCC to be a little different as...
