Work at the workbench has resumed after a very pleasant trip to France. We timed it well, and went a week before Kent’s roads closed, and came back the weekend after. I’d have been more impressed with ‘erself than I usually am if we’d planned it but blind luck sometimes plays a part!
I have made some more progress with the goods shed, the office roofs are slated and when dry will be trimmed and fitted to the skeleton of roof beams, which if I was both careful, and lucky enough with the glue, will then be removable.
The steps were a faff to put together, if the bottom step had been made with a “tail” to fit between the side pieces, it would have been much easier to assemble them square. Anyway, they came out close enough, and a touch on the Lidl disc sander made it a snug fit.
suggestions for flaunching (Sp?) on the horizontal edges of the thicker brickwork would be welcome. Current thoughts are filler (potentially messy, inconsistent) or profiled strip plastic or wood.
The other big thing on the workbench is the boat’s port gearbox oil cooler - this appears to have sprung a leak, as the gearbox ended up half full of mayonnaise, and clearly we were losing oil through the raw water coolant going into the exhaust. It was not a comfortable job to get the damn thing off, it’s awkward and heavy, and full of oil so messy too.
And of course, I had to drain & flush the gearbox, and refill with clean oil, and I’ll have to do that again, at least once and maybe twice when it’s all back together, to ensure the gearbox doesn’t start rusting from the inside. Oil’s expensive, but it’s cheaper than metal.
Anyway, I have cleaned it all up, have purchased new o-rings, will laser cut a new gasket, and put it back together to pressure test it. Hopefully, it was an o-ring leak, though why it should, I have no idea. Unfortunately, it’s more likely to be a solder failure, so it’ll be out with the big torch, and a new tub of Powerflo. Not looking forward to that.
Apart from that, I have to help MissD fix her LED torch, seems to be a button failure, but almost impossible to test without three hands (possibly more), and I need to fit a lamp housing & wiring to one of John’s signals.
I’m also looking at possible designs for surface-mounted servo point motors, for John’s layout. I’d like a cam arrangement so the servo can travel pretty much full throw and not overload the points or mechanism, and I’d like to 3D print it so I can repeat as required. Suggestions welcome. I shall revisit Giles’ thread as I recall he did something like this, but not with servos.
