Model dimensional features:

The kit is in the style of the Durango turntable. I have spent a lot of time searching for drawings, studying pictures and tried to get the kit as close as I can as the real thing for within functional and cost limitations. The intention for the kit is that it is a reliable, affordable, functional turntable that is easy for an average modeller to assemble and looks "right"

Lets have a look at the detail.....

* Bridge is as per the Durango drawings I have for length and profile.  it will turn a K class  - just like the Durango TT does.

* Bridge side panel overlays that simulate the iron girders of the original have scale plate sizes and number of the original. There are no rivets - but the tiny holes are there and you can always apply rivets individually  - and then count them! :)

* Deck width and planking deck planking is correct for Sn3.

* Deck cross ties are the correct number (32) according to drawings and pictures that are dated 1965, and as close to 8"x8" timbers as I can get them.. It seems the deck and bridge timbers have been replaced since the sixties as modern pictures have more ties, closer together.  I have cut them from a single piece for 3 reasons: 1) you can only see the ends when the deck planking is in place. 2) the single piece adds to torsional rigidity of the bridge frame 3) I want to offer an easy-to-assemble kit, not a bag full of sticks!

* Durango style angled deck stanchions , as well as "vertical" stanchions are included. piano wire handrails included - they stay stiff!

* I've added the air motor and operating deck that drives the bridge wheels. (Air is taken from the loco being turned in the real thing). The "motor" is made up from laser cut parts and is a fair representation of the shape of the unit. It does the job from reasonable viewing angles. This can be omitted entirely.

* Pit depth is as per Durango drawings at the bridge support rail and at the centre. The Durango turntable pit wall is a rather cracked concrete wall. As I am cutting from wood, the edge panels are easily bent strips of ply that glue in place around the wall under the edge rim, and then the surface can be treated to taste. Its an opportunity to make your own "cracked concrete". We are modellers after all!

Turntable operational features:-

* designed for 0.6RPM GW370 style motor gearbox . Search EBAY for "0.6RPM motor geabox" usually £10-£12 with free shipping. also found sometimes on Amazon.

Motor is NOT in the kit.  The shaft coupler to connect it is included , and so are the 4 M3 screws needed to hold it in place.

* Pre-assembled turning plate with contacts that transfers rotation and power to the bridge as per the On30 kit. with a milled brass insert that holds the 4mm primary shaft which is both pinned and glued. It works without slipping!

* Bridge rails....rail assembly is a strip of Sn3 track, the "ties" sit in the holes of the deck tie frame. The track is not included. so you can match whatever rail you normally use. The base of the rails sit directly on the tie frame. it is easy to centres the track and glue into place. You can't see any of this when the planking is in place!

* Pit is made up from, laser ply plates with a bracing panel and an additional ring carrying the support rail at the right height. All self-aligning with holes and 2mm axles (supplied).

* Bridge support rail in the pit uses a jig to obtain a good circular rail correctly centred in the pit. Circular perfection is not really needed because the bridge wheel design can accommodate a lot of "assembly tolerance" without fouling.
