'Nettlebed Lime' - 16mm dead steam

Just a suggestion - it would be nice to see the rather prominent Hackworth valve gear slide reversing with the loco reversing. :) The late John Noble did that in an S scale LMS tank way back 60 or so years ago on its Walschaerts gear. It was a DC loco and there were two motors - a traction motor and the motor for operating the valve gear. As far as I can remember, the valve gear motor was the primary motor in the loco and this sensed the polarity of the voltage on the track and moved the valve gear in the appropriate direction, then operated a switch which brought the traction motor into operation, and switched the valve gear motor out of circuit. There was a bit of circuitry with diodes to make sure this worked satisfactorily.

The loco was actually featured in the Model Railway News in the mid-60s and I might see if I can dig out my copy to double check that I've remembered things correctly. :)

Jim.

The Tattoo is complete, and we have a wall at the back of the layout! It will be nice to have a simple layout to run at Uckfield!

Fantastic Giles - looking forward to seeing the layout at Uckfield.

A suggestion if I might be so bold - the kick back siding in my view would be the ideal space to park another item of rolling stock?

I saw that there has been some discussion on pointmotors. Like so many, my favourite has always been the Tortoise ones, but I fitted my own printed motors to Nettlebed Lime, and by now they've had quite a bit of playing with, and I must say I'm very pleased with them! They're the same ones as I have operating 009 and 0-14 test pieces - just with stiffer wire, and although the 16mm points are much heavier and stiffer, manage fine. I have them operating off a single AA battery for my convenience, and a little Wall-wart that plugs in to power the LED route indicators on the panel.

They are slightly different from the norm insofar far as there is only a single button to operate the motor - to 'change' it, rather than pressing a specific A or B button to select the route.

They are FDM prints (3 parts) plus 3 microswitches and a slow N20 gearmotor (around 30-60rpm 6v is ideal, but I think I may even have 12v running off 1.5v)

End of last week, a kit for a Corris brake van arrived from IP Engineering, and I've been building it up since. Generally a good kit, with a couple of crudities as these laser cut kits have, it's turned out quite nice. As per Adrian's suggestion, it will be sitting on the kick-back siding, rather than forming part of a train (though it's quite capable of running).

I had to lower it by reducing the height of the frames so as to match coupling heights, as it will be fitted with choppers, not buffers, hook and chain. The only crudity i really couldn't live with was a piece of wood to represent the inverted channel from the sliding door. Fortunately I had son brass square section the correct size, and cut a slot in one face with an abrasive wheel to produce the right sort of channel (think 40 x 40 Unistrut - which I think is probably what is now fitted). This gave the opportunity to make representative runners for the door, linked by a bar at the top to fit within the channel, to attach to the door, instead of the lasered image. Add a dummy wheel to the bottom of the door, And one has a working sliding door.

Still to do is to fit the roof, make and fit the couplings.....

Lovely job Giles - I‘ve built a fair few IP Engineering kits over the years, but the crudities always left me feeling a bit disappointed with the finished item. There’s nothing in the least bit disappointing with that brake van - I must clearly try harder!
