I have had the working bee. Again thank you to all who came: Roger, Brendan, Chris,Trevor,
Allan, Bob, Graham, Jack. Progress was achieved and most people had something to do. I were wandering around as
usual.
A lot of backscenes went in tonight, all upper level ones. I am using 3mm ply as it bends enough for me.. starting on the peninsular and heading around three 90% curves. On the other side it just went the length of the station. A lot of work wa sinvoleved cuttng and fitting the 3m ply. I were happy with the curves, esopecially the 90 % one on the wall, it bows out , does the curve and bows in nicely. Especially as there was alot of cutting to do. One brave soul spent the night cutting balsa sleepers. Not happy with my crude jig, he improved it making productivity better by 3x - he cit a lot of sleepers on the night !! Trackwork wise two EMRC club members came as well as this other group and were tasked to finish the headshunt. They go the hald track in, and got one 2nd rail in, as well as corrrecting the curve next to the point. Another crawled awoudn the floow a bit cleaning up good stuff from paper and wood - thank you indeed. After the working bee, my intererst was up. So the next two days (apart from some interruptions) was spend down in the room. Wiring the sections for real, I were prepared with wire, cable ties, cable clips, conduct, and the sub baord attached to the railway. Since each block went to a lightbulb, the wiring was all logical. Each section has a wire to every track section. Noticed one of the bulbs was shattered, will replace it later. Next was gapping one section - ie cutting each circuit board sleeper to isolate the rails. Then a quick multimeter continuity test - all ok ! Will have to insititue a pull wire system soon. MY "conduct" system may not be as good as real conduct - I have a few pipes attached to neaten the main runs. Meanwhile I have been busy trying one of my "auto central locking kit" units as a point motor. This I did on the Sunday while watching the Sandown 500 V8 motor race. I implemented my shut down circuit as well. There are three microswitches ont the unit - two for the cut off sand one for the frog polarity. The circuit work ok and I'm surprised it only needs 3V to work. That was surprising, but thay means it will not need al ot of power to run. There is a monor problem - to much power and the system bounces a bit. I'm reasonably happy. I tested just by hooking it up to a powerpack and just reversing the voltage. I attached a microswitch to my two manual devices as well. I am yet to get some "non streatch" fishing line and set up a full mock up. I might try this ont the 3fold layout (see below) |

On another layout I have, a folding layout designed to firt my Corolla, 70% of trackwork is done.
Only plain track to do now. This has been a diversion of sorts to themain layout, but who cares.
It may be attached at a later date anyhow. It also is a miniproving ground as well.
I will trey the manual devices on this layout first. I had thought what to do, make the points manual or electric, and then what to use as a point motor. I'll try the manual first. Trouble is at the moment is where to have the controls if manaul. If electric I can make a plug in panel. |
