Brian's 7mm Diesel Workbench, Belated up-date!


Recommended Posts

I'm trying not to be tempted Brian :-) It is certainly going together a lot quicker than the DJH variety!!

BTW, welcome to the early retirement brigade!! I have NEVER looked back :-) Can't wait to see this finished... must resist...must resist !!

Edit for ps...I absolutely love your 4TC and 33/1.....

I eventually found out it was easier to add the 4 inner brake blocks that attach to the rear of the sideframes first before you fit the sideframes to the end stretchers, checking that the wheels rotate as you go. I found that I had to file the blocks back a bit as they rubbed on the wheels.

Then I added the outer brake blocks with the slack adjusters to the chassis. Once set then I attached the sideframes to the end stretchers whilst screwed into the inner bogie frame to hold it all square. The etched brass brake pull rods were then soldered on the outer brake hangers together with the safety strap.

The handbrake linkages are glued into place.

Airlines are made up of 5 castings that can be soldered together one at a time on the model. Just be careful with the iron and don't touch the resin!

 

The airlines on 47004 are a bit unusual as the bogies are secondhand from an ex sandbox fitted 47. So the airlines go up and over the frames instead of along the face so as to clear the sandbox when it was there. Also of note is that the spring on the brake linkage on the corners of the sideframes were removed on these to make way for the sandbox but never put back so they are missing on these locos.

The delrin cogs needed for these kits are 10 tooth ones. The one one the gearbox axle needs cutting back to fit. I fitted it with the teeth next to the gearbox and with the teeth next to the bearing on the leading axle.

Cab interiors can be put in after the model is painted. The glazing can be put in after painting too. I have painted this in all over cream as looking at my pictures I cannot see any evidence of a lower green band like these green locos had when built. Transfers on the rear bulkhead are from Railtec as are the dials. Before anyone tells me I know the dials are the wrong way round, they should be black with white increments but these don't really show up in this scale. But I stand to be corrected if you can show me otherwise.

Unfortunately JLTRT did not supply the radio telephone handset but I had a couple from previous DJH kits.

Had fun putting the windscreen wiper operating knob casting on!

These closeups do show that a bit more touching up is in order with the paint brush.

It is going together quite quickly I suppose. Glad you liked the TC, it looks even better being pushed round a layout!

The kit has a nice set of castings for the pipework that comes out of the battery boxes. But it's for a 47401-420 generator. As you can see in the pictures the pipes go from the battery up to the lower bodyside where as on the series built locos it only goes over the top of the batteries. So I will make the pipe runs from wire.

Some pictures of how it's all coming on. The buffers are only pushed in at the moment. The handrails are supplied as lost wax castings but I prefer nickle silver wire so these will all be changed.

I have today glued the cabs and roof to the sides and fitted a few more castings. Now I am away for a couple of weeks so no more progress unfortunately but here is something for you to ponder over. Can you get something to illuminate the headcode. It needs to give a nice even light to illuminate the old fashioned style numbers. There is not much depth if you drill out the headcode box, I don't want to make up a box arrangement in-front of the secondman to hide a light if I can get away with it, it needs something like a thin strip light?

https://www.simplyplastics.com/catalog/acrylic-rod/c-24/c-82  Use Perspex or acrylic rod to feed the light up to the head code box.  A small blow torch or similar will help to bend the rod to shape.  Then add a light source and place to rod ends in front of it and the ends will glow in the head code box.

You may want to add some black heat shrink sleeving over the rod after bending it.

 

It is available in many colours too.

Best.

After a nice break in Germany and Yorkshire I have been back at the 47.

 

Found a way to fix the snowploughs by making a bracket out of some milled U channel I had and soldering the etched bracket to the top of them. They are fixed to the chassis with a small self tapper so can come off for painting.

One slight problem though is that the handbrake gearbox is hitting one of the brackets as it turns. It might not matter on large radius curves but I think I will grind away the etch to get a bit more swing.

All the bufferbeam detail now on

Finally found where the small triangular casting goes by studying the instructions with a magnifying glass!

Electrical conduit from the battery boxes made up from 1mm wire to represent a series parallel loco.

I am off to Devon next week so another bit of down time on this loco. This retirement lark is wearing me out, I'm never in!

 

Whilst in Yorkshire I popped into the Embsay and Bolton Abbey Railway to see 47004. Looking a bit sad for it's self but doesn't look too bad but I think it should have been covered up. Looks like it's still got the Railmatch paint from 2000 when it was re-painted for the Old Oak open day.

I have now drilled out a tail light each end and fitted a red lighthouse LED and drilled the fronts for a DJH headlight casting. Couplings are CPL but mounted on the JLTRT hook as that is the correct size to go in the bufferbeam slot.

Also added the little clips on the bogie corners that used to support a sandbox. Although 47004 never had sandboxes the bogies are off a loco that did hence also the lack of return springs for the brake rigging where the sandbox would sit.

Had a look in my spares box and found a casting nearly like the drain pipe that was not included in the kit.
