Re: Exactoscale Products

Terry asks what our plans are for selling rail assemblies for turnouts in future. Our impression is that the market for the point kits as originally offered has been undermined by two factors.The first is the high price asked for the kits once moved to C&L and the second was the decision to sell...

Re: Chairs and Rail

I am trying to chase this through to a conclusion. To do this, I need samples of recent production of both mild steel and HiNi NS to do all necessary comparisons. I only need an 80mm length of each. It must be recent production and I need to know where it was purchased. Can anyone help? If I get a v...

Re: Chairs and Rail

This is a problem that could be caused either by too 'fat' rail or by chairs in which the rail space has reduced over time. Perhaps worth saying that the Exactoscale chairs were developed using rail from a substantial batch of code 75 mild steel BH rail I had delivered in 2003 (Some from Bernard Wel...

Re: Exactoscale Products

OK. I was mostly surprised at the question about pricing. The standard price list applies to all outlets and is available on the site. The 'online service charge' will apply to all purchases from, and only from, the Exactoscale Products site. It is defined in my announcement as (currently) 10%, adde...

Re: Exactoscale Products

When is it expected that the Societies stores will have track components and have pricing available ?

Sorry, but I'm not going to spend time answering questions when the answers are on the site.

Re: Exactoscale Products

I guess one should not expect great accuracy in postings on RMweb but it is a pity when carefully worded announcements have their meaning altered when ‘quoted’. What is ‘Exactoscale’? I am not the 'owner of Exactoscale’ but of the tooling and existing stock. Exactoscale is not a company and the arra...

Re: Ultrascale now closed to new orders

All a bit surprising. If you want to get tyres made, the unit cost falls steeply with batch size (and I can't see why that would be different if you made them in your own workshop rather than buying them in). At least with tyres, one size can usually, with few compromises, be used for a range of dif...

Re: Ultrascale now closed to new orders

Some of this reads as though I never made my announcements of 5th and 15th May. Exactoscale carriage and wagon wheels will be available, with the end of July as the targe date. We may have to hold back a little on this as sorting out supply of axles and bearings is proving more difficult and it woul...

Re: Exactoscale Products

This statement - "Exactoscale was up for sale prior to the arrangement with C&L" - is nonsense. Exactoscale has never been up for sale. Why, in ignorance, write something so categoric?
The tooling and stock have, since Exactoscale Ltd was wound up, been owned by me.

Re: Exactoscale Products

I thought an update on my announcement of 5th May would be helpful. Initially, priority is being given to making carriage and wagon wheels available. The stock position is such that some turned components needed to be ordered and delivered before we can get moulding of wheels underway. Stock levels ...

Exactoscale Products

With the sale of C&L by Pete Llewellyn to Phil Reid, it was assumed that the Exactoscale product range would similarly move and continue to be part of the C&L ‘offer’. As owner of all tooling for Exactoscale products and owner of existing stocks, I also made this assumption and hoped that th...

Re: Maximising Adhesion using Electronics

I think we all tend to look at things from the perspective of our own modelling interests. Mine are how to operate trains weighing up to 3Kg on a main line with 1 in 100 gradients. A particularly demanding requirement is how to accelerate a train from standstill in the storage sidings to a scale 80m...

Re: Maximising Adhesion using Electronics

For what I'm suggesting, it's not motor speed that needs to be measured nor the rate of change of motor speed - it's abrupt changes in either motor speed or the rate of change of motor speed that's required. I now picture a thin slotted disc on the motor shaft as likely to be best for detection with...

Re: Maximising Adhesion using Electronics

What we’re mostly talking about is taking advantage of the fact(?) that static friction is greater than sliding friction. Equalising axleloads (after allowing for weight transfer effects, which are often ignored) and making sure the suspension design keeps axleloads equal is a logical starting point...

Re: Maximising Adhesion using Electronics

No, I was thinking of a typical 6-coupled chassis with a single motor. In concept, what would be needed is a rotational speed signal from the motor shaft, perhaps a toothed wheel with a device counting the passing frequency of the teeth. As long as the loco was accelerating without slipping, the pas...

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 tr...
