| He could have made it without a garden metal thingy. You've seen his welded bridges | |

| Marty,
Looks great! How does it hold up under a 75lb locomotive? What are you using for a center bearing? I have a base and top ready to go whenever I get a roundtoit. But, what I did was I took a piece of 1" pipe and welded it to a 15" quarter inch thick piece of plate steel. Might have been stainless. Anyway, then I took a piece of round bar and welded that to the bottom of flat piece of steel 48" long. In the pipe, I inserted a 1" grinding ball. The only issue I have so far is that I need a better stablization bearing. Or some kind of outriggers like you've made with screen door guides. I also need to add some stiffeners under the flat steel since the moment created by my mikados causes noticable deflection...

| Marty, that's a fine looking bridge. I'll be anxious to see it this September at the Thingy.
One thing though. I would suggest that you put a slight inward cant on your rollers so it will follow the curve without binding. | | | |

| Marty,
More turntable pictures.
www.portjervisny.com/fr-turntable.htm
I found out that the "bridge" over the turntable receives power from an electrical pole. The power is then fed downward to the control house [if present] and to the motor below that actually turns the track.

| Marty,
Sorry.
The term "bridge" for the arched superstructure over the turntable was MY use of a word. I have been unable to find a name for it yet. The rotating track portion of the turntable is called the "turntable bridge." Tomorrow, I will call my friend in Newton and see if he can find out the proper name.

| The 1939 Railway Engineering and Maintenance Cyclopedia states: "On electrically operated tables, the most desirable method or supplying power is by means of collector rings attached to and overhead framework at the center of the table."
The 1942, 1945, and 1948 edition use the same wording in a nearly identical article with only size increases and the increasing use of roller bearings updated. The publication became the Railway track and structures cyclopedia for the next edition in 1955 where turntable and transfertables are not even mentioned.
I have heard them called bridges, curent bridges, current collectors and many others including my personal favorite a "harp" it sounds ellegant and it can't be confused with too much else on the railroad.
In summary, call it what you want, just like the railroads.

That mirrors my experience. The farther I get into this, the less I seem to know. But it does help to see what the other LS-ers are doing with their layouts. Your work, like much of the other projects I have seen here, is really inspirational. It seems that our members are getting to be specialized experts within large scale. | |
