4mm Inside Motion parts for Slaughter Goods

 I finally got the Slaughter Goods inside motion drawn in a way that they will print consistently. There are four parts; left hand (a) and right hand (b) slidebars, which have the ram pump on their outer side; the valves (c) in the centre with their eccentric rods and links and connection to the underside of the boiler; and the lifting links and weighshaft (d) and weight that attaches to the front of the motion plate. The lifting links on this loco attached to the top of the eccentrics quadrants.

This shows the four parts in roughly their correct orientation, the valve rods should be slightly lower and the eccentrics slightly higher.

These are b, c, d and a from the top.

You can, hopefully, see that the right hand crank drive is above the axle with the driveshaft towards the rear of the slidebars and the left hand crank drive is in front of the axle with the driveshaft nearer the front of the slidebars. The eccentrics are also in differing positions so the quadrants are slightly out of alignment when viewed from the side. The weighshaft has the bearings on the shaft and these can be affixed to the front of the motion plate. The assembly should be able to be fitted from the top and bottom of a running chassis. The parts could be glued together and then attached to the insides of the frames using the pump valves and the cranks and eccentrics can rest on top of the axle.

Very difficult to photograph!

£10 a set including UK postage. 

7mm Craven Slaughter Standard Goods being developed

 I think many of you know I am designing and making more in 7mm scale nowadays and have been wanting to re-scale the 4mm Craven Slaughter Standard Goods for a while.

Here is a photo of the etches and some of the 3D resin parts for the 7mm version.

There are still a few parts of the 3D designing to do. One major part that I was unhappy with was the dome, safety valves and levers unit. I have now redesigned this to be made up of four parts as follows.

I have just pushed these parts together for a photograph, no glue yet. I am a great deal happier with this aspect now.

So, now for a test build and write the instructions.

I am awaiting some wheels for the loco so will start on the tender and probably publish it on RMWeb with a few shots here also.

Cheers, Ian

Hornby 4 wheeler accessorising

 

Foot board and guards lower footboard

Footboard for non-brake vehicles

Hornby have provided us with brilliant renditions of near Stroudley carriages that are let down by, in my eyes, two main things: the grab handles and the footboards.

I have designed and printed these two types of footboards to be a quick super glue addition. 

One piece printed footboards for non-brake vehicles; £4 a set. One piece footboards for brake vehicles with lower footboard; £6 a set.

See later about grab handles. Roxey are available.

I have also designed a 4 wheel sprung underframe etch that fits the Hornby carriages beautifully, along with 3D printed 6 foot or 7 foot axlebox spring units and buffer sets, either one piece or two. A short length of spring wire is needed to operate the springing units.

The etch plus EITHER 6 foot OR 7 foot 3D printed axlebox and spring units with a set of one piece buffers is £12. Two part buffers instead of the one piece for an extra £2 or £4 a set if ordered separately.

3D printed Guards lower footboard set £3 if ordered with a chassis etch or £6 if separate.

I have also drawn up 9 spoke wheel centres - these are fitted to MGW P4 wheel tyres as shown, the first attempt to the right and the current, slimmer type, to the left. I haven't been able to try these on Alan Gibson wheelsets yet as I haven't got any! A set of four 3D printed centres for £4, you provide the tyres and axles.

The 3D printed grab handles are shown on the Hornby 1st class carriage above which is sitting on one of my etched chassis. These grab handles have either a base printed at 45 or 90 degrees, suitable for whichever situation, as required. They just superglue into position, very easily, if you have a small pair of tweezers to hold them! These are a pig to get printed so I would only be persuaded to sell these if people twist both my arms. Roxey's etched brass ones are available.

Postage would need to be extra for all the above. £2.50 minimum as they would need to be large letter postal rate due to the thickness of parts.

I intend to get some other Hornby carriages accessorised in the next few days so this blog will be updated when there are some other photos to show.

Cheers, Ian
