Almost done. Lady Jane is up on blocks and in steam for adjustment and testing of her new RC. Forward/reverse control was OK and needed no further adjustment. Regulator adjustment cannot be finally set until the loco is in steam, as the replacement valve doesn't have a definite end stop when closed. |

With steam available I attached the control arm to its spindle without the push rod attached. I adjusted the valve and arm so that steam cut-off corresponded to the "ten-to-ten" position. I closed the servo from the transmitter stick, and then re-attached the control arm and push rod. I opened the valve very, very slightly and then tightened the push rod retaining screw on the top connector. The instruction sheet points out that the "O" ring will compress with use, so re-adjustment will be needed in time. A single grub screw didn't always provide sufficient "bite" to lock the control arm in position on the brass spindle. Ever helpful, Roundhouse have tapped the control arm hub twice with screw holes on opposite sides, so I was able to use a second grub screw taken from the manual arm to lock the RC arm firmly in position on the spindle. |

Body re-assembled and roof open (right image) the wires feed up through the cab close by the roof's front hinge. The receiver swings up for access. All leads unplug and the roof "module" can easily be detached from the body. I still need to lengthen the power lead from the on/off switch so it can join the main "loom". Leads need to be kept clear of hot components. When the roof is closed, they run by the relatively cool gas valve. Lady Jane poses in the rain (lower image). The only external signs of her RC conversion are the unpainted regulator valve and the aerial cover on her roof. She takes the tunnel, cutting and track behind our aly greenhouse in her stride. The job was made much easier by the HBK10 pack, and having all the required holes and cutouts already pre-cut in the manual loco's footplate. |
