When I planned having a set of module in the shed that could be interchanged I expected to be concentrating on OO but Im getting carried away with On30 at the minute.

Here is the outline for Narrow gauge module 2



A mini Roundhouse, well not very round really !!!

I have a turntable (A dapol OO kit) that has been built without the aid of the instructions to get a wider deck



The supplied plastic wheels would not be of any use to anyone so something beefier was called for.





Running on code 100 rail to supply power to the deck track. It very much a work in progress at the moment but its simmering nicely !

Good adaptation of the Dapol kit, John. Is that plsticard you've used to make the turntable bed wider?

No Ive just stuck the girders on the side of the deck rather than on top in the supplied grooves.

here are the pictures of yesterdays progress, after cutting the wood yesterday, last night I fitted some covers over the guide wheels and glued the track down. It runs well but I have found that the deck can twist lightly due to lack of cross strength. When there is a little bit of weight on its fine. As for deck to baseboad height it is is nearly spot on so just a tiny bit of shimming (less than 1mm) may be required.

Electrical contacts, im wondering if rather than putting contacts through the wheels to the rails if I would be better just having a wiper strip under the deck onto the rail?? It wont be seen and wont restrict the wheel rotation and reduces the number of contact points. (wiper to rail wiper to wheel to rail)

I would say wiper to rail less contact points that way plus a wider contact area as wheels only contact over a very small point of track but the wipers can contact over a larger area.

On the Dapol turntables I used, I fitted some flat brass shet - very thin , to the base, split into two parts  with wiring going underneath  to allow auto reversing as per 

On the table wired to the two tracks, I used phosphor-bronze springs out of cassette tapes -bit of foam on them was part of the tape tensioning system & all bits super glued  - table shown upside down.

Had no problems with this method.

That's a brilliant idea, Ron. So simple yet so effective.

Thanks for the advice, as you have all suggested the track is now fed from wipers, under the deck that rub ontop of the code 100 rail that the wheels run on. (2 cassettes tapes no longer play :) )



The bed of the table has worked out at just the right height to match the baseboard top.



To get the rails lined up, I got them as near to the centre line of the table as possible, then pinned a scrap bit of track to the baseboard. By keep rotating the table through 180 I could check the other end of the table line matched the fixed baseboard track. A couple of tweeks and I got the track to line up perfectly at either end.



And here is a video to show it works

The bell is ringing to show the table is live through the pic ups, every where except when the pickups go over the insulated section that creates the split in the feed rails.

i still can't work out how you find the time to fit this all in, when i think of something it slowly evolves and mostly changes direction a few times. with you one minute mossley terrace the next a 0 gauge loco, rolling stock and a new module:brickwall

Never one to give up some more head scratching, then I realised when I fitted the new wheels it caused the deck to sit higher and so the centre support ring didnt support the table. So I cut out the centre support from of the baseboard and glued it back in with plasticard underneath.



 The table could now only sink about 1/2mm in the middle, try again.... Still didnt work.  Table still sunk to much at the feed end when the mighty loco edged on.
Then I realised if i got the loco all the way on the ends settled back out again.... Mmm.

Finally I glued a piece of plasticard under the deck directly over the metal guide rail but so under no load condidtions it sat about 1/4mm above and clear of the rail.



Success !!! When the hulk edged on now, the table could physically only drop untill the  plasticard packer under the table hits the rail (1/4mm) Once the loco is centred on the table the weight is balanced and the packer raises back of the rail a touch!!!!!



End result all the modifications have made improvements, but the packer helped the most, not only does it hold the table in balance whilst being loaded but an unexpected bonus is it acts as a brake, stopping the TT rotating whilst loading, releasing automatically when the loco is fully on :)  It may wear over time if it rubs on the rail top but it can easily be replaced.

The moral of the tale, never underestimate the weight of an On30 loco !!!

This evenings progress

Track down





I was about to take a pair of wires to the outside of each line to get power to them and realised I could do it the easy way with a "busbar round the pit, combined with the rail.



On one side the back rail is fed from the outer copper wire in the pit and the front rail is fed from the TT wheel rail. On the other side it is reversed.



The wires will be hid under scenery
