The Workshop at the rear of the roundhouse was accessed through the shed - across the turntable - and via four 20ft turntables one for each of the workshop repair bays.
By the 1950/60s - the period I am modelling - only two remained in situ the other two having been removed. Repair bay 2 remained in use for minor repairs whilst bay 4 contained a wheel lathe. Wheels were dropped on the hydraulic wheel drop and rolled to a small turntable at the end of the wheel drop road [ Number 14 ] and then into bay 4 via the forth 20ft turntable.
The 20ft turntable on the road for bay 2 which is off to the right. The covered wheel drop is in the background.
The small size of the turntables prevented all but the standard 8ft x 8ft 6in wheelbase Midland locos [or smaller ] from entering the workshop so their use in later years diminished.
So to the model. I wanted a pair of working 20ft loco turntables and contacted Peter Harvey of PHDesigns who produced two 3D printed kits of parts for me.

The parts were given a coat of etched primer from Halfords and are shown adjacent to their positions at the rear of the shed.
The 3D prints are designed to take Alan Gibson sprung plunger pick ups which touch the underside of the running rail and connect to phospher bronze etches on the underside.
Here are the two turntables in position
and finally a Jinty 47544 on turntable 2 with the 5mm foam underlay in position.
Now for the rest of the trackwork!
