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.

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...

I've used an RSU (an American Beauty model) for a number of years with some success but have never been entirely happy with it. Your video was excellent and has given me a lot of useful ideas to improve my use of it. I can only second the suggestion that you tackle other subjects because your prese...

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 ...

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...

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.

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...

Just a source of small gears I've not seen mentioned :

I don't have any experience with them, but they had some interesting sizes.

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...

There's some discussion of using grit blasting to prep for paint in this other thread : viewtopic.php?f=39&t=3837&p=75447#p75447

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...

Curiousity led me to google - this link suggests an MT1 taper for the RandA

Cheers gents. I need to pick up that book.

I may not be able to order Precision's primer but now I know where to dig, and can compare with stateside offerings.

1. Precision etching primer thinned as per Ian Rathbone's instructions. Gents this is all fantastic, thank you. If I may ask a newbie question, where may I find Mr. Rathbone's instructions? And, can you tell me what brands of primer? I'm in the USA, so finding a similar brand may be a challenge - I...

Thanks Folks. I had noticed that very interesting thread, and need to read it again more thoroughly. It certainly does echo some of my interests. (I had meant first war, too.) I must confess it's well more than one or two issues of MRJ by now. And my copy of Rice's books on etched kits are well read...

A bit late to dig up an old thread, but the content seems relevant. Hello, I'm a new member, located outside Seattle. Hello from down south. I've been interested in various aspects of model railroads for many years. Recently bought some MRJ magazines which have been inspiring. Combined with a long-s...
