Re: 0-6-0 diesel yard switcher

You always fix the rotating member to the bearing, and a loose fitting axle is not what you want to do unless it is the outside diameter that is being spun. You press fit the axles into the bore of the bearing so that they do not move relative to each other. For example, if you have an idler pulley,...

Re: Woodinville Shops

Very nice railroad!! Impressive. Maybe you should investigate building a working sander for this locomotive. Harry Bean used to have working sanders on his 1 1/2" 2-8-0, and they were disguised as tanks under the running boards, with manually activated release valves that would dump sand on the trac...

Re: Nelson's tube expander

I've used an expander similar to what you describe, tube rollers, and also made swages to seat up tubes several times. All three methods work well, and if it will pass the hydro test then it will stay that way for the life of the tube, unless you do something like dry-firing the boiler. In any case,...

Re: blind driver

I've had the blind driver on my 2-10-0 drop in behind the outside rail in a curve before, so I would be concerned about it on a locomotive as large as that Mikado. If you have a curve with any kind of a slight kink or outward push where a rail joiner is, then you can have that wheel fall inside behi...

Re: Passenger Car Maroon

I wouldn’t worry greatly about an “exact” shade. Nobody that was alive in the 1800’s is around today to say whether or not you are right or wrong. Not only that, but paints faded over time, so are you modeling a brand-new car or freshly shopped one, one that has seen a few years of service, or one ...

Re: steel tires

I have read somewhere that some locomotive builders also used a 'high adhesion profile' on their driver tires too. Don't remember exactly where, maybe in Europe? Not sure. The profile was such that it made the largest contact area with the rail head to promote better grip. I believe that the composi...

Re: steel tires

You do not have to make a step in your tires... But I would recommend that you do that if you are not going to press your wheels off of the axles. The chance of you getting it to set in the right position without a step in that scenario isn't very good. If you are going to tire up a wheel off of the...

Re: West Coast Steel Rail

Was a group down in Florida that imported a bunch of it, from Belgium I believe. That was about 4 or 5 years ago. About 4 clubs went together to make up an order, and the Florida club(s), whom I can't remember right now, did the leg work and led the effort. CSME and Mid-South each bought a few thous...

Re: A Little Machining Problem

I always drilled the saddle first. Then I clamped the saddle and the smoke box together using all thread rod and a couple of pieces of scrap, mounted them in the mill, and then drilled the holes. Make yourself an extension for whatever size bit you are using so that you won't hit the saddle with the...

Re: Regauging pressed on wheels

The ones I've seen had a noticeable dip and lots of wear up near the flanges, and then at the outside edge of the tire, there wasn't much wear at all and you could tell that this part of the tire almost never touched the track. With the really wide tire on there to set the flanges back, the outside ...
