Model Forum / General / Railroads / June 2007Turntable
I'm looking for an 00 turntable for a new layout I'm building ( British outline) I need one that is reasonable flush with the surface so as I don't want to cut out any baseboard. Drawn to the Hornby Electric one but note it's designed to work with the Hornby R965 controller. I use H & M controllers and would like to know if I could use this as an alternative to the Hornby one using the DC output ( 9volt I think it is) and an inline switch. I assume the diameter of the turntable is about 12inches Any help appreciated John > I'm looking for an 00 turntable for a new layout I'm building ( > British outline) I need one that is reasonable flush with the surface Why not try the Dapol (ex-airfix) one, you'll have to motorise it yourself (or gears and hand-crank - whatever you prefer) but it lies on the surface of the table, the only hole you'd ever have to make would be a 1/8" bore for a rod to operate the thing. Also being a kit you can modify it to your hearts desire alternatively it makes a very good bridge. Just a thought.

Believe the motor was the standard X03 used in the locos at the time. It also had plastic ramps to reach the correct level. Will check out Fleischman . I know they have a good reputation.

I assume the diameter of the turntable is about 12inches I wanted an N gauge turntable and, as N gauge ones are rarer, finished up getting one from Atlas in the states. I believe they do a OO version as well. It comes as manual but you also purchase a motorising unit that replaces the handle and is enclosed in a hut. It sits on the baseboard (only holes are for wires) and has a Geneva motion that stops it briefly lined up with each track as it comes to it. Can't comment on noise as I haven't got it installed yet. Total cost including packing was £50 so with the exchange rate it was only £25 and it did not get charged by customs. However if you do get one, and are concerned about customs charges, order the table and motor unit separately, that way each package will be under the £18 cut off below which customs apparently let parcels straight through. (the £18 figure came up in an earlier topic in this group). http://www.atlasrr.com/ SignatureKeith Willcocks (If you can't laugh at life, it ain't worth living!) > I wanted an N gauge turntable and, as N gauge ones are rarer, finished up > getting one from Atlas in the states.

The prototype railways built TTs to suit the locomotives in use at the time - the diameter often limited the locomotives that could be employed. Major depots TTs got upgraded when top rank locos exceeded their length but lesser stations often retained shortish TTs. A too short TT on a layout can be an interesting operation limitation meaning that the bigger locos have to be sent elsewhere for turning. (adds interesting light loco working) The other advantage is that 12" TTs and loco depots are really big, whereas (say) a 9" TT and depot will take about half the space.

The ex=broad gauge turntables in Devon and Cornwall were built for Gooch's 4-4-0 yank engines. After gauge conversion they were so short that the Dukes and Stellas operating there had specially built short tenders. And a similar situation prevented the Dean Singles working through to the Northern division. >Greg.P. > >> > The Atlas HO turntable is only 9 inches diameter, thus not large enough > >> > for 00 Pacifics.

What will Brunel think of next? ;-) The point I tried to make was that turntable upgrading was normally behind loco upgrading everywhere other than at major stations. On my own layout the turntable is only large enough to handle a 4-6-0. Bigger locos generally work through. If for some reason a 4-6-2 is allocated for trains terminating it can run straight across the TT into a shed bay but it can't be turned. That requires a light working back to ... It hasn't stopped me buying bigger locos, but the restriction on station operations makes things more interesting.

It would do. I've never had a turntable because I'ven ever really needed one. But one of my pet hates with the proprietary ones, is that they stop where you wouldn't want them to. They all seem to assume that the modeller has a roundhouse or similar, and even then they stop in too many other places. It shouldn't be too difficult for the manufacturers to implement a more flexible indexing system. >Regards, >Greg.P. > >> >> > The Atlas HO turntable is only 9 inches diameter, thus not large enough > >> >> > for 00 Pacifics.

Some of the smaller GWR turntables could be fitted with angled extension bars to allow larger locos to be turned. If my memory is right an example is Minehead which originally had a 45ft turntable but when bulldogs and 43XX locos they could be turned by the use of extension bars to increase the length to 50ft. as a temporary measure until the larger turntable was insatlled.

This continued on for most of the LNER days as well - B17 numbers 2800-47 ('Sandringhams') were built with short-wheelbase tenders based on the GE 3700 gallon type used with the B12s. Later members of the class (the 'Footballer' ones) had the larger Group Standard 4200 gallon one. Did anyone ever do a RTR model of the 'Sandringham' B17s with a short tender? The only B17 models I've ever seen are the 'Footballer' ones.

The Atlas HO and N turntables are both the same size, just some alterations to the moulds are made for HO vs N gauge rail spacing. Their first HO turntable stopped at 12 positions and the N TT stopped at 24. Circa 10 years ago the 12 position HO TT was replaced by the 24 position version. These all have a "Geneva" mechanisim which causes the table to slow and stop at each track position. The table length is 230mm, in HO equivalent to 20.25m which is close enough to 20m, which was the standard DRG turntable length prior to the Einheits 23m tables required for the large Pacifics and 2-10-0s introduced in the mid 1920s. IOW it's long enough for smaller Pacifics. ;-) Greg.P. > The Atlas HO and N turntables are both the same size, just some > alterations to the moulds are made for HO vs N gauge rail spacing.

But only 17.5m or 57.5ft at 4mm/ft scale. Too short for 00 Gresley or Stanier Pacifics.

Bear in mind that with the Hornby turntable you are restricted to the exit roads being at 22.5 degree intervals - this may be a problem depending on your layout design. Have you considered the Heljan offering? It does need a hole in the baseboard but comes with excellent documentation including a paper template for cutting the hole. The indexing system for any position exit roads works a treat. SignatureBill Campbell > Hi John > [quoted text clipped - 9 lines] > documentation including a paper template for cutting the hole. The > indexing system for any position exit roads works a treat. Thanks Bill I guessed it was something of that size. I'm still at the planning stage and have ordered some ready made baseboards up to 3'4" in width narrowing to 2' (15' long.) Intend to have a station layout with a fiddle yard at narrow end. . May have to put a turntable at the fiddle yard end and run light engines through as per Kings Cross in steam days.

Long story I guess, but in a nutshell both shop and home escaped the floods even though we were subjected to the monsoon conditions. There was heavy flooding in many parts of Hull, the nearest about half-a-mile from the shop. In North Lincolnshire we had around 4½ inches of rain in twelve hours, but Barton remained upon Humber not in it. Again there were heavy floods within three miles, and we struggled to get to out for our pub lunch yesterday (Monday's our day off). The main A1077 was closed in nearby Barrow upon Humber and there was isolated pockets of flood water in many nearby communities.

I have the Heljan turntable, the only problem I have is that when it turns 180 degrees, it does not line up accurately, it is almost the width of a rail out. I have had to halve the error and not have it 100% lined up both ways Does anyone else with one have this problem, or have I got the lemon. Pete |
