Re: AMB wheel masks

I wondered about all those sizes too. I got the Proto 2000 one and have used it on every 33" wheel I've got: Intermountain, Rapido, whatever TMW uses, etc.  Both .100 and .088.   Key is to use a rubber band as shown. Spray with Cammo brown from a rattle can gives the wheels that unpainted but even rough texture. Pop them out and a quick couple of rotations with the fingernail on the shiny surface and you are done!  Very durable finish too.

I just push a length of insulation from an appropriate size of wire onto the axle end. I use a long enough piece that no paint finds its way to the axle.

Re: AMB wheel masks

Dennis Storzek
 

I have a slightly different take on this, but it may be applicable. I got tired of the paint chipping off wheel rims (the outer face of the tire). Most turned (as opposed to Kadee die cast) metal wheels are nickel plated, and nickel is a hard slippery surface that doesn't hold paint well, and is resistant to etching with mild acids like vinegar. So, I decided to abrasive blast the wheels to give the surface some "tooth". Problem is, one can't wipe off the roughened surface, which means the tread and axle point both need to be masked (I don't bother blasting the wheel backs).

To make the mask I drilled a 3/8" hole through the end of an Accurail car weight, not only because I had one at hand, but also because Accurail weights are .078 thick, just the right thickness to mask the whole tread on a Code 110 wheel ( a thinner piece of metal would work for Code 88 wheels). After drilling the hole, I used some fine sandpaper wrapped around a 1/4" dowel to gently expand it a couple thousandths to fit  a scale 33" wheel.

I then took a piece of 1/8" brass tubing a couple inches long and flattened all but the last 1/4" of it, then bent the flat portion into a "jug handle" shape so when the flat portion was affixed to the weight, the round end of the tube covered the axle point. Once both parts were made, I grit blasted them to increase the adhesion of the epoxy I used to assemble them. I fit a wheelset in the hole and positioned the bent tube to cover the axle point and fastened them together with a gob of JB Weld. Not elegant, but effective.

To use, I clamp the mask upright in the blasting booth, and hold the wheels in the hole with a gloved had, blasting first one wheel face, then the other. The thickness of the car weight protects the tread and flange, while the tube protects the bearing. The bend in the tube makes room for the stream of abrasive to get to all portions of the wheel face. The same set-up could probably be used as a paint mask, but I'm not interested in cleaning the mask, and just brush paint the wheels.

How do folks on this list deal with that? I’m currently dull-coting while still in the truck (while the wheelset is spinning), then subsequently removing the wheel and brush-painting everything to avoid painting the needle journal (usually successfully).

I’d prefer to airbrush them if I can solve that issue.

Micro Mark has a liquid masker. A drop on the axle ends and paint doesn't stick.

Tim, all prototype 33" wheels aren't the
same size :-) 
33" works out to .378 and some change in HO scale,
unless the
manufacturer used 1:87 as the scale factor, then it's a
bit over .379.
Since the tread is tapered, there has been continuous
disagreement about
where the diameter should be measured. I know the Accurail
molded wheels
measure .380 at the root of the flange fillet. When you are
trying to
produce a press fit paint mask, size matters, as they say,
so AMB has
decided they need three masks to cover the range.

Steve,
A general drawing of the car was published on p. 263 of the 1937 Car Builders’ Cyclopedia. This drawing shows a vertical-staff hand brake that few, if any, cars actually received. For developing a scale a model it provides the basics. It’s the version having straight side sills between the bolsters and an upward bend towards the corners.

The National Museum of Transportation has ACF drawings for the cars they built, and the Illinois Railway Museum has drawings for cars built by Pullman-Standard in the 1930s to early 1940s. Both of these sources have not only general arrangement drawings for specific series of cars, but they also have other drawings such as brake arrangement, side & end construction, floor sheets, and various steel details drawings for the underframe & other components. 

Please advise if you have a specific railroad in mind & I can provide specific lists of ACF drawings. Paper or digital copies of the ACF drawings are available. 

Regards,
Ed Hawkins

Thanks for that, Tony.  I have done some digging and figured out why my recollection was wide of the mark - I was confusing the falling reefer medallion with an incident in the UK of a passenger being injured on a train when the smoke deflector of a passing locomotive came loose.  Apparently I have too many railroad/railway interests and not enough filing cabinets upstairs to keep all the information organised!
