It is well worth a look, if you're going past. The whole place is OK, too - plenty to see (on a nice day).

It's behind a pub called the Old New Inn. A distant relative, who was a cop in Harlem, New York came over to visit us - it was like one of those comedy films when people go to places they just don't understand. I had to shepherd him around the place and I remember, me being about eight years old, trying to keep an eye on a twenty stone New York cop. We were in the pub when someone jokingly asked him if the bulge in his jacket was a gun and he just produced a loaded .38 snub-nosed revolver and handed it to the bloke.

This was before hijackings and airport security - he just put his gun on every day like his watch...

A model of a model? Hmm, a weird one all right. The Schrodinger's Cat paradox of the railway modeller? I'd say it's a first....

It is possible that the model of the model village in the model village may have a model of the model of the model village in it...

In fact, i think it does.

 

The model of the model, with the model of the model of the model in the distance.

If only!. Burton on the Water is just lovely, Model Shop there too. Lovely Little Stream for messing about in runs through the Village. Fairford and Brize down the road too!

 A Trip to Chipping Norton to see the restored Bliss Tweed Mill  and Chimney is also well worth the Journey if your in the Area.  Modern Buildings simply do not compare.

In my day, Little Rissington was still in action at the top of the hill - Central Flying School and home of the Red Arrows back in the Gnat days - great entertainment five days a week.

Sad news in the Model DART Workshop- following a slight altercation with the Guinness DART at the Raheny Show, the long running display DART25 retired to the workshop refusing to drive in the forward direction. In the shop on the rolling road it refused to run at all and protested with bellows of smoke and that distinctive whiff of burning, the motor was removed and a post-mortem was carried out at 8.00 this evening;-

If you are anyway squeamish now is the time to look away

On opening up a small piece of copper fell on the bench! on removal of the brush nuts and close inspection of the brushes- one had a sizeable chunk missing! and spying through the hole one could see where the copper came from- the rim of the commutator (just above the arrow in the pic). We can deduce from this inspection the cause of the failure- the crash into Guinness DART jolted the motor causing one of the worn brushes, loose on its spring, catching the rim of the commutator and chipping the piece off and a piece off the brush in question.

This motor has been on the go since 2013, it would run each month at shows, sometimes twice a month for the duration of the show, not to mention when run at home. It has done a fair amount of mileage and probably would have kept going had it not had that bang?

It's not dead yet- spares!!

That's pretty worn alright! I'd say it's done quite a few hundred thousand scale miles! The amount of shows that has run all day without missing a beat has been incredible!

Here is a thing I haven't done in a while- build a DART pantograph;-

These are the moulds for casting the four main parts in white metal.

After cleaning up the parts the hole drilling starts, this is the lower arm upper pivot being drilled .5mm for brass rod pivot.

Lower pivot of the upper arm drilled .5mm and been tested with the brass pin.

Testing the two arm assembly pivot fit.

The main frame pivot holes being drilled and test fitting the pivot pins- .6mm dress pins. I use paraffin wax to lube the drill bits when doing white metal, that lump in the photo left has been with me since I was 9 or 10!!

Cutting the dress pins for the lower arm/main frame pivots, the arm crossbar has been drilled in 4mm both ends to take the pins.

1402216385_OTB-12520200628_173839.jpg.ebab491130ba6082d452c1d15eed2bf4.jpg

All works so now for epoxy gluing, the pin heads are glued to the main frame only, the shafts are then free to allow the arm rotate.

Top of panto is soldered to the upper arm with lead 70deg solder in a little mdf jig to get things aligned and leave the two hands free to do the soldering.

The springs are made from plastic coated jewellery wire 'Tiger Wire' some call it. The upper spring is bent double and will be epoxy glued in the front end of the lower arm where a .8mm hole has been drilled. The lower spring is bent double with little hooks bent up at each end to catch the back of the main frame for epoxy gluing.

Springs on and fixed with glue, the centre arms pivot is glued also only on the outer ends of the brass pivot.

Plastic cast roof recess and panto lock down pin set up, the hook is .4mm nickel silver bent up and soldered at the fixing pin end.

Lock installed by gluing pin through into drilled hole in the plastic box upstand.

And complete.
