Progress control panel.
Finish storage frame guides.
A conference was called to discuss the positions for the main elements to go into the box. The space required for each was assessed and a layout agreed.
1) Heavy duty latching plug and socket for the power supplies. Geoff had a rummage and came up with an identical unit as the main panel. This will connect to a 16v AC unit for the speed controller and a 19v DC unit (ex-laptop) that will be housed in a floor box. 2BA brass bolts will be located in a plywood yoke bolted to the floor of the panel. Holes have been formed in the panel fascia for LED indicator lights above the terminals.
2) General wiring terminals. Rather than traditional connector strips, the old panel used brass nails in a strip of plywood providing soldering posts. We tossed a coin and went for brass nails again. Geoff made and marked up the ply strip and Laurence and Stephen bashed in the nails.
3) Loom egress hole. One critical factor was where the cable hole was best suited, bearing in mind that the panel will be in two different positions and orientation, depending on whether it is used in the shed or an exhibition. The different mounting options also had to be assessed including the front-of-house option in the shed. It was easy to forget the cut-out for the flooded quarry requiring a position overlapping the fiddleyard. Once agreed, a hole in the panel base was drilled and a wooden block for a rubber lined, steel clamp to hold the wires securely was also fitted.
4) A small Vero board for the three relays required to turn the on-off point switches into forward-reverse switches. Laurence was tasked with preparing a piece of board, but a chance word regarding the new point servo operation made us realise that the relays were no longer needed, as the point control system required on-off switches. Scratch item 4!
Stephen completed the manufacture of simple 9mm plywood strips to guide the boards into the storage racking. Geoff apologised for not getting around to the external coat of primer, but it wasn't critical.
