Just starting to try and get an idea as to where I got to before my attention got diverted!

According to the spreadsheet I'm logging all prints in, I have so far printed 390 parts!! Where are they all?? :shock:

HI Doug

That is starting to look really good.
I take it that the bottom line that runs on the ground level underneath will be done ?

Regards
Graham :D

Just spotted Graham asked a question.....Yes, the branch line will be on the layout.

And on to today's progress....I've gone back to the trackwork over the Royal Albert bridge, namely the shallow point splitting the single line into Saltash station. I've made some more progress on detailing the track bed around the pointwork and am starting to tighten up on some of the loose bits:

The blob of blu-tack is to stop the track escaping during development...its not a pile of sand dumped by some idiot wanting to derail a train!

The next bit is to work on the moving plate....the bit with red markings on. I'm torn between soldering a wire directly to the bottom of the two lengths of rail that sit on the plate....or to use single rail track connectors. I think I'll form the rail sections first...then see how well they sit in the plate.

I'm moving on with the design for this point...….

It looks as if once I get the moving rails made up, the point may actually work! Here's the point with 3d printed rails that I've marked the rail head in black so they're clearer to see:

The tails of the blades should be longer...but there's a limitation to how thin a wall a 3d printer can print!

Doug, superb job on the points. I made up a dummy #10 and not so ambitious to try making it work, yet. Now one of these days, we will have mixed media 3D printing (metal and plastic) and we'll just print the metal rails into the model, eh? :D

Getting closer.....two print iterations further on for both the track bed and the moving plate:

I think I'm on the last print for the track bed in its final colour....and there may be one or two iterations left for the moving blade, as I still have to work on getting power to the two blades.

I'm using a RC servo to drive the blade movement and have a part-built electronic power switch-over unit that is driven off the servo control signal. Both blades and the vee track section (at rhs of picture) plus just under a centimetre of one rail on each of the connecting tracks form the "live frog" section.

Hi Dough,

perfect work!

pls, place the actual electric point beside your points and take a foto - so we will see the relation of your development

Thanks.
