Re: HO scale gears

When John Cummings, now deceased, was with NWSL, they offered a range of 0.3mm modulus straight tooth gears intended for use in logging engine models.  I have no idea if these are currently available.

I once ran across some fairly fine pitch gears intended for light electric flying models, while pursuing small size coreless motors from Ebay.  I think they were about 0.2mm modulus, but the size range was quite limited.  I've no idea what the website was, but you might search for such sites. 

I can supply 16mm ID Fulharber ~1008:1 spur gearheads, with, I believe, 0.1mm modulus gears, so 1/3 the tooth size of NWSL's smallest.  Without checking, I believe these use 5 stages of 9-tooth x 1.5mm long pinons and 31-tooth x 0.5mm thick gears, with a much heftier 13:27 output stage.  These were removed from gear-head motors purchased from a local surplus store ~20 years ago, and might still be usable.

And of course, if you have access to any old windup watches, the smaller ones contain really fine gears.

Ebay sell plastic gears .you can buy a whole bunch for robots and models cheaply from china.A great source of non specific gears

Have seen the pictures and ads for the San Juan Conoco tank cars, thought they looked great.

Was in Billings this week and saw the pre production models in person.  As great as the pictures have been, they don't do them justice!
The cars in person are just beautiful !  Can't wait for the production line to be delivered.  I have four ordered and they will be a great addition to the fleet.
Great job San Juan!

In principle, yes.  Practically speaking, this is probably something they are not set up to do, certainly not on a production basis.  So this will be a custom job,  and they will need to add an extra charge to recover the cost of the requested work.  Which you should expect to run a good deal more than the cost of one of their Pullers.  Custom work isn't cheap.

Re: Central Valley trucks

Funny how you just mentioning that brought back some memories of a trip my new wife and I made through Denver to San Francisco and then down to the LA area where we visited with I think I was Geoge Hook of Central Valley.  It was located in kind of an small industrial area, medium size building.  We walked in through the open front garage area and on our right side were a line of women on punch presses, after that another assembling side frames, never saw someone put springs in so quickly and rarely lose any.  Then she put them on a test track where they rolled down an incline and into a tray.  The track had a light bulb which went on if there was a short.  On our left side as we walked in were stacks of prepainted plywood for cars and assembly boxes.  Then there were 55 gallon drums full of wheels, axles, trays of thousands of springs, and other parts for cars.  Over the years the cars are still being built and are just right for some of us period modelers.  I do a lot of repair work and if the finish is really screwed up I refinish the cars and put Clover Dry Transfers on them.  You can see my efforts on www.SierraScaleModels.com and look for the craftsman car section.  I have done over a hundred refinishes. They might not be HOn3 but still quality cars for ideas.

Re: Central Valley trucks

Bryian Sones
 

Jim,

I thought about that too but I couldn't get my wheel sets to move. They were probably pressed on.  I didn't try a wheel puller though.

However NWSL makes this HO Scale Wheelset, 26"/88, 2.0mm x 1.015" Pointed Axle (4/pkpkg)

If you have ever ordered from them then you know they make your wheel sets per order.
So I messaged them and asked if I could have the wheels set to their hon3 spec.
I am waiting for their reply.

OM has 26" wheels.  To use the CV trucks you would need to make a standard gauge bolster, and fit narrowed wheel sets to it.

Hi Tony, do you know OM actual wheel spec? 
Is it a standard gauge 33 wheel set to 3' or 26 wheel set to 3'?
I think NWSL wheels allow you to move both wheels on the axel. 
If that is the case, I can use the CV trucks with the NSWL wheel sets and set the wheels at 3'

Central Valley trucks

John Stutz
 

The old zinc alloy Central Valley trucks were die-cast with a noticeable draft angle.  Being sprung, the angle at the top of the side frame's bolster slot tends to force the side frames to pinch the axle ends. IF the axles are tight in the sideframes, with no end play, filing or scraping this area square to the sideframe may free them, allowing the trucks to roll freely.  Only the top needs to be squared.  A slight reverse draft may be needed, but try just squaring first. We want the axles just free enough that end-wise play is detectable.

To remove truck springs, use a fine chisel pointed probe that can slip under one end and then be tipped down inside the spring, catching it as it jumps out..  A slightly curved tip may help.  When reinstalling springs, retain escapees by temporarily running a long loop of fine thread through the spring,

Rotary snowplow trucks were often not sprung, presumably to keep the hood from catching on the rails when plowing. Toneyk's front truck photo shows a near solid rubber pad arrangement that gave a bit of cushioning without yielding the way that springs would allow.  With sprung  trucks like the CVs, one can model this by cleaning out the spring seats and substituting a solid block for the springs.  For equalization, leave the block about .010" shallower than the opening, so the bolster is free enough to twist a little.

Hi Brian and All,

If you have,or have access to the 2015 HOn3 Annual, check out my article on work equipment. I described how I substituted old Central Valley archbar trucks for those in the kit. To be sure, it isn't perfect. The rotary hardly rolls at all but the "fix" looks better and my model, if it ever appears "in public,"  will just be on a siding. There isn't much room under the plow either for truck rotation. I also used Grandt trucks under the tender. It is a great old kit but as far as operation,not so good.

Re: Hon3 Durango Press Rotary Snow Plow OM kit trucks

With the truck under OM being standard gauge with wheels set to 3' you can also graft the kit side frames onto a NG truck.  Like a Micro trains heavy archbar.

If your model is set before 1962, you need to replace the tender.  The huge current tender was from the Uintah #30 before being D&RGW water war W-499.  It was mated with the OM in 1962.
The original tender was from a class 56 or 60 loco and was much smaller.  It was set on a double stacked frame.   OM, ON and the RGS plow were all set up that way.

Hi Bob,

Someone suggested to me Precision Scale, brass, K37 side frames. This kind of makes sense. However, if you want them to look accurate I would think you would need to mill down the bolster spring on the K frames. 

Then maybe cut and shave the spring assembly from the DP side frames and somehow attach the casting to K side frames. For the Ice break bar you could probably use the set from the kit or fab your own.

Central valley archbar trucks, hmmm...  I do have several sets of those. 
I'll see if I still have that annual but I'd really would like the Snow Plow to roll freely for operations. I have the work cars to use with it too. It would be a bummer to have it be a static piece. My layout is set late winter-early spring. so you can see why I would want it to roll. If it was more off season I wouldn't care.

Thank you for that suggestion. I will look into it.
