Failing that, how feasible do you think it would be for me to fit the worm myself, using a mechanic's vice? It looks like it is theoretically possible, but do you think there is too much risk of motor damage - bent shaft, etc.? I would still have to buy a new worm from Peter at the same time as a wormless motor, because my existing worm can't be freed from my current motor. Definitely Plan B.

It seems that that the turntable gear is the same as used in an X.03 powered loco, and that therefore the X.03 worm should work...if it has the length to reach the gear? Ignore the DCC Decoder connections to the hut for the R410 TT, this drawing is for a motorised bridge R070 TT and not the manually rotated R410 version. That gets me to outlets. Your system will be fine on these where they are not connected elsewhere in the layout. If they are connected elsewhere and thatI used to produce this 'adaptor', initially as a 'service' to model railwayers, but have found it financially unviable. The Hornby method of conversion is a bit brutal and will invalidate the guarantee. There are a few different ways of converting for DCC and may not require removal of the bridge The special worms are also available....just need a worm puller to remove existing worm....and a method of fitting new worm without damaging the motor.... The Round Hole part is the one that was desighned for the Electric Motor Operated version of theTurntable. (Only Elecric Motor Operated versions have been made for many years now...including the current issue).

Kerry, you've now used up your two posts until this time tomorrow. If only you had answered ALL my questions like Q1 & Q4 in the absence of full answers. I shall now have to make some assumptions to fill in the gaps. I was planning to use a 2-pole centre-off switch with a supply of suitable voltage, once I have got the motor in and tested to see what it needs. In DCC, are the turnouts made live by the roating rail turning to them, or must a separate connection be made?" IF, I wire one rail to + and one to - then surly when I turn the table by 180 degrees, I will get a direct short. Yes?"The square hole is for the square 'pin' on the end of the "Water Crane" to engage in...turning the Wayer Crane operated the turntable...
