My position is that Nadel's formula is proven and the consequences are that models should be heavy (or at least heavier) compared with the worst expected impulses from bumpy track, and evenly and equally loaded per wheel. Looks like confirmation bias -- We like heavy stock, therefore heavy stock wo...

2. Find a way of making a slot in the cosmetic axlebox such that it can be fixed to the axleguard (W iron) but still leave freedom for the bearing to move within. I can see that forming a 2mm wide slot for this purpose can be difficult, and that using a drill bit larger than 2mm to create the neces...

Thanks for the replies. I’ve attached an image which hopefully illustrates the problem. Too little of the 2mm side portion of the bearing protrudes through the slot (due to the use of spacing washers on the inside). As a result, the axle end can move from side to side in the slot instead of just up...

I'm thinking minutes, not hours, for a properly designed chassis KIT. Every thing that is operational pre-shaped and fits what it is supposed to fit to. No parts to fettle, no parts or partial assemblies that need adjusting or measuring and cutting to size. But you must have an accurate wheel press...

I'd ask a bunch of 20 year old Chinese girls to do it...

Look at the deep shadows at the tops of the spaces between the windows, just the same as the end droplights.

Sorry, I can't send this by PM.

Slight diversion - do you have a .pdf you could send me of the instructions of your now withdrawn carriage set couplings? Lost mine Mike You mean the cast brass ones? I don't think there were ever any instructions for them. You just bolted them on one coach and hoped for the best. I am working on s...

With a 3 mm difference in axle centres you should be able to arrange a CBS that goes over the carrying axles and under the driving.

Your sliding axle solution? You mean this one? Note the date.

An Easter Day debate revolves in my mind Will. I don't see how the scaling effect of physics favours us particularly. A 16 ton wagon scaled down 76.2 x 3 times gives us 32g 16 tons was the permitted load. The tare was 7-8 tons. So a mineral wagon could weigh anything between 7 and 26 tons, and the ...

Very clever, but using the ball mill will give the wrong shape to the flare. Deeley Chimney.jpg Note the difference in radius of the flare on the two views. While having a constant flare radius would not be too noticeable on modern locos with large boilers, it will stick out like a sore thumb on old...

Tool wear, backlash in the machine and the fact that the datum for the depth is the back of the flange?

We should try access the tartan paint technology that figured so often in the Beano and Dandy.

making things is what some of us enjoy. Otherwise why not just do what so many do, and simply get our models from the wide range of RTR products available. I don't envision the end of etched kits or scratch building or even modeller produced etchings for scratch building. If prototypical accurate d...

I note that Etched Pixels sell 1:148 kits with etched sides and a printed armature. I think these are the original Ultima armatures. They are a clear injection moulded box, which is a lot easier to produce in 2mm scale than 4. A printed armature would not be very much cheaper than a fully printed c...

I prefer separate door and commode handles. So a kit with holes for these (or markers showing where to drill) would be my choice. Commode handles can be made from wire, not too difficult if a folding jig is part of the kit. Door handles are easily made from brass lace pins with a file. Now here's a...

On the subject of what is in a kit etc, etched kits come with separate door handles which are not usually overscale so why not printed vehicles? After all, such will require a number of other components, for example grab handles, to complete so why not door handles? Because the whole point of print...

Yes, I know you were talking about the moulded handles, but what do you want instead of them? Are you really expecting everyone who buys a kit to have to buy the door separately? It seems to me that you want to replace a reasonably scale representation of the handles with something that is likely to...

it looks good but would it be better without the door handles ? Then people could put there own choice on and it would save trying to carving them off neatly..

You mean; you think manufacturers should supply coaches without door handles so customers will have to supply their own?

So how many people want H class wheels?

Drop me an email if you do.

I don't think I can do them before S4N but you shouldn't have to wait 10 months.

Thanks for mall the info. Dullcoat is obviously not acrylic base so no good at stopping UV at 405 nm.

Does anyone know the formulation of Dullcoat varnish? in particular is it acrylic based?
