N Scale Rotary Coal Dumper
Posted by hepkat63 on Monday, November 15, 2010 3:27 AM

Hi All,

as I am too stupid to make one - is there anyone out there kind enough to offer their services?  I would like a fully working Rotary Coal Dumper in N Scale.  Not sure if this is the place to ask - but I if I am posting the wrong area please let me know?

I have scavenged the web for two days, and seen a few guys have made them, but no one is selling them.

 

Please drop me a line if you can help out.

Yet another kit that is offered in HO, but not in N.  Like the Walthers Hulett machine.  To properly model a facility using a rotary dump, you really need a pretty large area.  In N scale, that large area doesn't take up as much room.  But if the model doesn't sell well to HO gaugers, who generally have less space proportionally to work with, N scale gets denied the product.  While the models themselves might be similar between one scale and the other, setting for them is vastly different.  It might be easier to sell 3,000 rotary dumps to N scalers than to HO guys, simply because we can fit them on our layouts more readily, or we can build it into an N track module that fits into an even larger layout.

But, N scale remains the red haired step child...

  Walthers have offered a rotary dumper for thier Superior Paper Company(at least in HO).  The kit was all plastic and could be made to operate with a great amount of work.  Being plastic, I suspect the bearings/gears will wear out quite fast.  If you are planning on doing a unit coal train, you will need working rotary couplers of course.  I would suspect that even a good working rotary dumper(even in HO) might have problems with unit train rotary couplers.

  That said, I have seen pictures of working single car rotary dumpers with a kick-back track on HO and N-Trak models at shows.  Of course they were all custom built.

I might be interested in having a rotary dumper in N scale built.  Are you still thinking about it?

Hi,

I have a Nscale rotary coal dumper .

It was manufactured    30 years ago and I beleive in very small quantities by State Street Models owned by Mister Rick Spano ,a well know and precursor modelist in Nscale.It was also reviewed in MR "New Products" at this time.

Mister Rick Spano layout is featured on a web site whith picture of a Rotary in Nscale but I don't remember the address.

It is a pewter kit very hardly constructed.

 For the story, my late father ordered it for my birthday.

 I have buid it and dismantled it soon after and left the parts in a box.

But  I project to rebuild it because my new vision of my maclau river is now meanly inspired by the N&W which owned one of two rotary at Lamberts point terminal.

What I remenber whith this kit and as a rule is to use only one brand of hopper; it was designed for 33' hopper and I use only MTL hopper.

For a scratch project , may be use a Micro enginering  deck girder bridge; use a small aluminium tube like Mr Koester used in his tall viaduct project to it more rigid.

You can cut the two round end in a small aluminium plate;some little iron factory could do the job.

The chutes could be made in styrene.

The pressure arms which retains the car when rotating are more difficult to do  and I don't remenber how they work on my model but I get to take a look and made some pictures I will publish in this post in the coming days

I beleive also MR had published an HO plan of a working Rotary in end of the 40's or begining of the fifties.

Some which own the New CD of the MR complete issues may find the plan; it was also published in an extra old book  by Kalmbach for scratchbuid projects.

Hi,

After reading this post and following my previous answer I make some research of my old relics.

As mentionned I never rebuild this rotary and let it in pieces in a box.

Unfortunately I didn't have fund the instruction.

I was so happy to share the infos whith You, I rebuild the rotary after 30 years yesterday evening.

I must admit it's a crude model whith not a lot of details but more important at all it's a working model.

I will detail it whith pieces of central valley bridge and some rivet decals and in a near future include it in a steel pier like the one which appeared in Lamberts point on the N&W.

More than a text see the picture I took this morning; the chute is a cardstock mockup I made quickly to show how the Rotary discharge in a ship.

I will scratchbuild a fully detailled chute in styrene.

The car used in the picture is a MTL 33' hopper.

The approach track need a magnet before the rotary and between the track bridge, so the car is uncoupled and the knuckle stay open; so the following car push it out of the rotary bridge when empty

I will use a small geared motor to drive it.

Marc

This has been my main criticsm of Walthers for years now. They seem to think that if a kit doesn't sell in sufficient numbers to HO modelers, they won't make one in N scale. N scale has come an awfully long way over the last 20 years, but it's still got a long way to go. Walthers is denying themselves significant profits with this short-sighted business strategy.

You responded to my earlier post that you were interested in building a dumper for me over the winter.

If that is so, please contact me at delvery@sbcglobal.net

 

Thanks,

Hi,

This site offer blue prints of numerous industry, machinery, great lakers ship and plan of the Sandusky lift dumper still in use today.

They are specialized in ghreat lake industry including the most famous Great Lakers ship.

These plans are plan of the real thing, but are very helpful when scratchbuilding such machine.

The McMyler HO scale dumper you can find on You Tube and watch some video's was engenired from these plans.

Same for the HO PRR dumper which win first award in 2007 at the NMRA ( seen also on You Tube)

Some plans are in a 1/16 scale and the dumper is in HO scale; to use it in Nscale reduce it of 54%.

Take a look at them at   www.bearcomarine.com

wow - where have 10 years gone!!  So, after a long hiatus, I want to get back into N scale again.  Given the amount of time between my posts... I'm wondering if technology has caught up with N scale and there is someone out there that can build me a working N scale Rotary coal dumper please?
