7mm Rob's Rolling Stock Workbench

[Rob Pulham]

Thanks Graham,
I do have a couple of Scale Signal Supply NER signal kits in the pile, so I will do as you suggest when I get to them.

 

[Rob Pulham]

Seeing Ruston's scratch build of a Timber framed Home Office 1901 cylindrical tank wagon scratchbuild on RMWeb prompted me to get out my previous effort.

Some of you may remember this from when I built my Slaters kit and replaced the supplied tank body with one riveted and rolled from brass? At the time I ordered some brass U section from Eileens and promptly left it on the back burner.



I cut and soldered up a basic frame following this plan





Apologies for the quality of the photo - I used a different camera and wasn't fully au fait with how it worked.

Below are shots of progress yesterday.

Very nice Rob, can I ask how you made the ends of the tank body?

Hi Scott, They are the bottoms of coke cans. You just file across the bottom of a coke or similar aluminium can until you are left with a very useable domed end of just the right size for 7mm tank wagon.

I keep meaning to get some of the narrower cans of the Red Bull type to see what I could do with them but so far I haven't got hold of any yet.

Rob,
I use the bottoms off John Smiths beer cans (I keep telling SWMBO they are stronger than coke tins ), these are the same size but taste better, hic.
I've been looking closely at the bottoms of hair spray tins, they seem to be the right conocal shape but a lot smaller diameter, can't make my mind up as to what to use them for though.

A little more done today.





Not as much done as I would have liked but I haven't felt too hot today.

Lovely work Rob, especially the riveting job on the tank filler. Will it be built rigid or sprung??

Now that tank filler is something else, especially the clamp bar. Very nice job..... now where do I place my order?

regards, Graham

From the back of the queue.

Nice work Rob

Thanks Mick, It depends to be honest - I have some etched W irons for it that are rigid but I may be able to do something about springing. The problem is that the Chassis is very open so to make it look right I will need to be careful.

Thanks Graham, I used your method for making the clevises at the ends of the clamp bar.

Want some more of the sprung version which you had for the tar tub?

 

[Rob Pulham]

Yes please Graham that would be most appreciated.

 

[Dog Star]

OK - etches for the axleguards and for the cradles.
How are you placed for spring wire?

[Rob Pulham]

I think I can sort the spring wire thanks Graham.

 

[Rob Pulham]

Tonight's endeavours have produced the discharge pipe assembly.

Produced in copper for no other reason than I had it in stock in the sizes that I needed.

 

[Dog Star]

And the chain to stop the caps getting lost?

 

[Dog Star]

Just a thought... at some time circa 1910-20 the inclusion of stop valves in bottom discharge pipes of Class A tanks was banned in response to the possibility of an "oops nasty" should the valves get knocked off. Which kind of means that given your modelling period then you must be representing a Class B tank.

Does not take anything away from the elegance of the product.

I had a feeling you were going to mention that..... I have thought about it just not got beyond that at the moment.

Why me?
