Building the roundhouse at Mount Forest...
#31
Well, I haven't made any progress on the roundhouse, but I have been working on the turntable for it.  It's the Walther's 90' manual turntable, about which there have apparently been some complaints., mostly regarding its operation. 

The main problem that I've noticed is that it doesn't roll too smoothly, likely due to the cast plastic bridge wheels, which have the mould seam right in the middle of the wheel tread, meaning that the tread is nowhere near flat across its surface.
There are also some issues with the height of the table's rails not matching up very well to the rails to which they can be aligned, but some spacers and a mill file will correct those problems.

I motorised mine, using the motor and gearbox from an old scanner, and run it, using power from a 9 volt AC wall-wart, routing the power through an old SCR throttle...

...which I'll mount on the layout's fascia.

I thought that the turntable looked pretty bland, so I widened the deck using various strip styrene, then added handrails, an arch for the power collector, and a new operator's cab, too.  It's not yet finished, but here are a few photos.

The handrail stanchion supports are made from short lengths of 1/32" brass tubing, along with a "steel" base plate cut from .020"x.100" strip styrene.  This photo shows the parts, the assembly, and the installation...

The handrail stanchions are Athearn's diesel handrail stanchions, straightened and inserted into the tubing, then secured with ca.  The handrails are Tichy .020" phosphor-bronze wire, chemically-blackened, then brush-painted with Scalecoat paint...

...and the operator's cab, with a barely visible control panel...I'll probably install an operator, at least for photos, as I've left the roof removeable...

The arch supports are from a Tichy water tower kit (thanks, Ed!), while the lattice-work arch is scratchbuilt from strip styrene.  It's based (loosely) on the TH&B's turntable at Chatham St., in Hamilton, Ont.   I've yet to add the electrical pick-up arrangement and an access ladder to the arch, and, of course more painting is required.

Wayne: I ran my turntables from the track power. I put a DPDT switch in to supply power either to the track on the bridge or the turntable motor -- less chance of driving off it while it's turning.

I have one of those HH2s on my layout.

In model railroading, there are between six and two hundred ways of performing a given task.
Most modellers can get two of them to work.

David, the HH2 powers only the turntable motor, while the track on the turntable is track-powered, and can be turned on or off, and controlled directionally by  switches on the layout facia.  The roundhouse tracks are powered through a rotary switch, which is also controlled by a separate switch which supplies the power.  With the exception of the turntable motor, it's pretty-well the same set-up as at the Lowbanks engine shop...

Wayne, I was just suggesting a precaution. We sometimes find at Lostock Junction that the operator balances the loco on the turntable, starts it rotating, and forgets about it when he moves another loco in the shed.
Not a problem at home, though. I forgot to leave enough room for the turntables in the new layout.

Yeah, turntables come with their own issues, and I've discovered that this one's track is not centred from end-to-end, despite care taken to ensure that it was assembled properly.  If the cab end of the table is aligned with any of the three tracks which connect to the turntable, the other end lines up perfectly with three corresponding roundhouse tracks.
However, when the non-cab end is lined-up with those access tracks, the cab end does not align well with any of the same three tracks.  This is an annoyance more than anything, so I'll just have to remember to have locos arriving at the turntable, pilot-first to go into any of those three roundhouse tracks, should have the turntable's cab at the point of entry onto the turntable.  That will at least let them enter any of those three stalls without having to adjust the turntable.

I'm not overly impressed with the motor-drive, either.  The table spins, in proportion to the throttle setting, but vibrates considerably due to the wheel issue, and it will also take a bit of practice to get it to stop exactly where it should. 

The best I can say is that the turntable pit at least closes the hole-in-the-sky over GERN Industries, almost immediately below on the lower level.

Looking good Wayne, I am glad to see you are making headway on the upper level.

Thanks, Charlie.  I seem to be finding less time to work on the layout, although I need to clean it up a bit, just in case I get a visitor.  Every so often on the local Fall layout tours, I come across some fairly nice layouts, diminished simply because there's dust on everything. 

I thought that if I forced myself to work on something, it would get me moving a bit, and it has improved my interest...I wonder what will pop-up to drag me away next?

I'd say that your moving right along... Engine facility going In,  and the layout up and running once more.  I haven't had the time to do anything since the spring. Nice work,  always good to see pics of what you are doing.

Thanks, Steve!

Well, I'm following all the stuff you're doing in 1:1 modelling, so I certainly would count that as doing something!

Maybe you should go on the Spring layout tours, just after spring cleaning.   Icon_rolleyes
