Roxy Mouldings Fox Bogies

For the low roofed NER coaches I need sets of Fox bogies. Initially I was going to resin print them but I would prefer etched brass ones. After a lot of research I couldn't find any with NER fittings, but Roxy mouldings sell an etch only kit, (all their others come with SR or its constituents parts) so I bought one as an experiment. Has anyone used these before? Any comments?

The main thing I have spotted is there is no mounting plate, so I presume they relies on washers packed to give the correct ride height, also the compensation uses soldered wire on top of the bogie, set lengthways on one bogie and crosswise on the other, again I will just have to see how things work out.

Fortunately I have an unbuilt NER autocoach, so I can model the fitting based on those in this kit.

All to play for when the underframe is completed.

 

Rob,

I've just looked up Kemilway bogies eyewatering is an understatement £67+.

Naked Roxy bogies are £8.50 a pair which is more than enough thank you, especially when you add in the cost of two pairs of wheels.

 

I wont ask how long ago that was, each coach is over £300 these days, so your £125 would be in excess of £1500. How times move on.

This is the Roxy etch:

 

First stage of creating the NER fittings, leaf spring absorber plate and fittings overlaying the etched side which I scanned the wrong way around.
Sadly the lower foot board support on this SR based etch conflicts with the absorber - to be resolved later.



Next on to the axle box.

If I did that the lefthand absorber mounting would sit half way out in fresh air, its already hard up against the edge of the etching.

 

Axle box done, the right shape but possibly not the right dimensions as I don't have a diagram. I'm sticking to "if it looks right ,,,,,", anyway there only me going to see it.



Now onto the really obscure bit the bolster spring. this one won't be easy.

 

Did you spot the error Rob, I'm just think through how to fix it!

Phew not as hard as I thought

 

Awake stupidly early this morning (4:30), I wish my body would accept I am retired and wake up at a sensible time so I couldn't resist having a go at the bolster springing.
Robs Kemilyway instructions again proved incredibly useful showing the basic shapes and relationships if not the measurements, so with a bit of creative licence and a number of false starts:



The two horizontal plates shouldn't be there they are to provide gluing lands on the etch.

And again a mock up with the spring axlebox assembly and a dummy etch:



I'm rather pleased with how it has come out.

 

Cheers Tom, yes it will help especially with the foot boards. The ones with the etch are very different to those in your photo.

Nowt wrong with the old way Rob, especially if you have the skills to do so!

 

Paul,

Since the printer is sat in a Baltic attic printing will have to wait till it warms up a bit, but I am also really looking forward to see how these fittings come out.

Based on Tom Burnham's excellent photo I have made a couple of changes to the spring assembly. The pin at the top of the spring assembly, I had slightly recessed. The photo shows it protruding slightly, also the mounting plate is significantly higher than that shown in the Kemilway drawings so both have been adjusted.



Now satisfied with the springing, it was mirrored to create the righthand spring assembly, and then mocked up with a dummy side frame of the etch.




Next are the footboards which are radically different to those supplied with the etch and some thinking about the mountings.

 

Now to work out what to do with the footboards. If you compare the scan below, which is the footboards for one side of the bogie with that in #14 above, these need scrapping. Not surprising as the etch is designed for LSWR, LBSCR and SECR bogies not an NER bogie. A simple full width single step needs creating.

Then if you study the mock up of the relationship between the etch and springing below the inner support is going need to be removed and replaced. Initially I considered using some waste etch to replace it, but again referring back to #14 there no representation of the step support on the side of the bogie. So the plan is to replace the support with a printed one, but also taking the opportunity to sketch the missing sections of the supports running up the side of the bogie. The two brown dashed lines, show where the replacement parts are going to be fitted.
