Re: CSB for a Single Driver
That's a simple question but I don't think the answer is simple. The position of the cg and the design of the loco suspension define the stationary stance of the loco. (Spring stiffness affects both height and pitch.) The drawbar force applied to the loco does not care where the the center of gravit...

Re: 3-foot radius curves in P4
A perhaps foolish question - north american railroads, both 12"=1' and 3.5mm=1', commonly use spiral easements, particularly where a tight radius is needed. Yet Keith's PDF makes no mention of such. Was that not done in the UK?

Re: On-line drawing scaler
Cheers Gents. I am aware, somewhat, of the principles involved in skewed images and un-skewing in Gimp. When I've needed it I scaled the skewed image, rather than tried to unskew it - that's down to me being familiar with drawing perspective views on engineering drawings, and not familiar with how t...

Re: On-line drawing scaler
That's fantastic Guy. I wish I'd had that for some drawings I did a while ago.
I think it'd be quite complex, but if you can see a way to handle a photo that is skewed, rather than square to the subject, that'd be a very useful enhancement.
Thanks!

Re: Adding operational interest to a engine shed layout
I would think late arrivals would be an occasional issue for all locos, esp.in poor weather. Similarly a planned minor repair might go awry. Perhaps dice or a card deck could randomly hit a few arrivals with a delay?

I'm wondering if they were trying to balance out the weight transfer when pulling. It should tend to transfer fore to aft and even out the leading and trailing axles.

Re: CSB for a Single Driver
Hi Stephan, in my mind the anti-pitch bar can't bear any weight because it is free to rotate in its chassis mounted bearings; a bump lifting the front axle would also lift the rear axle (which might be a problem in itself) and the loco will pitch nose-up to a new equilibrium attitude. Correctly app...

Re: CSB for a Single Driver
Simon, I've had similar thoughts. The difficulty as I see it - if one has an anti-pitch bar, it won't know the difference between pitch due to attempted acceleration, and pitch due to a bump under either the leading or trailing wheel. This would tend to reduce load on the driver near the bump, just ...

Re: Who would want a form tool for re-profiling wheels?
I'm interested. Side note, I saw an article somewhere. The author made a form tool by turning a disk, then cutting a notch in (with suitable rake). My point is, that tool was able to be resharpened many times. Not sure of the design being contemplated, and I'll buy it either way, just offering a com...

Re: CSB for a Single Driver
Been following with great interest.
It seems to me that even 30/40/30 might put too much weight on the leading & trailing. Clearly, going too far would lead to oscillating. 1/98/1 for example. But I'm wondering if 20/60/20 would work, or 25/50/25.

Re: Making a Start - The Peak District Midland / Monsal Dale pre 1903
Depending on how much wall is needed, if one built a segment or two, I'd think casting resin duplicates would turn out acceptable copies. The joints between copies could then be built up, stone by stone. That's painstaking, but less effort than building every wall in place. Of course that presuppose...

Re: West of Scotland Group's "Starters" Build a loco project 3
Interesting. The Paasche has a hopper on top, and flows the air up through the media, then back down to the nozzle. I suspect it'd fluidize the media a bit better than the Badger design. But I definitely needed more than 20psi - it flows media but too gently at 20 psi. Compressor ordered, it's in th...

Re: West of Scotland Group's "Starters" Build a loco project 3
Over in the US, Paasche offer a "air eraser" which is a small grit blaster. It's similar to Paasches airbrushes, but has a cup and nozzle intended for grit (hard, etc). Especially, the cup is a flow-through arrangement, not a gravity feed. So I don't know if an airbrush would properly flow...
