7mm Scale 7 MOK 9F in Spain

[Len Cattley]

It's now 2023 how time flies, have soldered the dummy hornguides, going to fit Grease Nipples but don't know if you can see the feed pipes Any ideas on this?

Also on the Brake hanger brackets, I want to make the brackets removable (there is 3 ways to achieve this) what is the best way to do this?

I have done the 14BA method on my 4mt tanks and tender locos it worked quite well.
I can see benefits for the 12BA method to as 12BA taps are slightly longer and more robust than 14BA ones. They are also cheaper and easier to find.
On your Grease nipple front you would need a magnified to see them I can hardly see them in a photo of a real one but if you are brave enough go for it.

 

[Len Cattley]

Thanks Mark, I think I will give the grease nipple a pass, I will give the 14BA or 12BA a go.

Hi Len

Are you referring to the 5 & 6 feed oilboxes either side of the middle wheel? If so I would suggest they're quite noticeable, but tricky to line up as my rather feeble version below demonstrates!

Yes there are the ones. What size is the wire you use?

0.3mm.

Do you know were they go?

Not 100% sure. There's the two that pop up over the top of the chassis and disappear into the dark recesses. The others I just routed to the various holes in the chassis. They're largely hidden, so I wasn't too fussed as this fits in with my 'impressionist' approach to my model making. I did spend quite a bit of time studying books and online references to glean more info and had I persevered I may possibly have come up with a definitive version, but I decided to call a halt.

This is the only pic I took as a work in progress.



The remaining three pipes (not added when pic taken) disappear into the round hole to the right. I haven't got any pics of the other oilbox. Next time I take the wheels off I'll take some pics and send them to you. But like I say I do apply some artistic licence to my interpretation!

Len.
Can't give a definitive answer but, looking at some photos of un-wheeled 9F chassis in the works, suggests that at least some of the grease pipes ran along the outside of the frames to the horn guides. Beware of modelling a model rather than the real thing. There's at leat a couple of preserved examples, so perhaps someone has detailed photos or access to the information?
Might not fully answer you question, but there are some great detailed photos on here under the gallery section, last entry 29 Aug 2022 under 9F Detailed photos, or something like that.

This is the link to the thread that I started before the 9f came out that you refer to above.

Prototype - 9f detail photos

With the pending MOK 9f kit getting closer it would be nice if we could start a 9f detail thread.. If this is out of place here then moderators please feel free to move or delete. Anyone who has close up detail of any 9f alive or now scrapped please feel free to add you photos. Please keep them...

That might be a thread that could/should be in the new “Resources” section, perhaps?

Mike,

The routing of the oil pipes puzzles me a wee bit. I understand that that type of oil box works by means of oil siphoning into the pipe via worsted wicks and flowing by gravity to where required. Oil could not flow up those pipes over the frames! Perhaps that round hole is where they should all go and the two over the frame are redundant but not disconnected. I assume you have a prototype photo showing them routed like that!

I don't know whether these will be of any help - they are hardly model makers detailed photos - but I just worked on these from Tim's collection. They'll appear later with full details, but they might be of greatest value right now and it is, after all, the type of question Tim always hoped his photos would help to answer. Both are of 9Fs being built at Swindon. Unfortunately they may not be the answer to questions about the nether regions.

92207. 25 April 1959



92206 on the same date.



I can do you a couple of "specials" if it will help and try to lighten up the underframe detail a bit.

And a couple of mine, my collection and copyright. 92203 at Liss as withdrawn in May 1970.



92240 Southall Shed 18 July 1965



And I've just found a couple more of Tim's, although these have been published previously.

Newly built 92178 at Swndon 19th October 1957.



92185. Swindon. 19 October 1957.

I think you're right. However, I'm probably not going to change them now as I'm struggling a bit to keep motivated with the build. They're pretty much hidden away anyway.

some go through holes in the frame, some over i think it depended what day of the week it was, all my pictures etc varied quite a bit

Hello Mike,

these are not oil pipes. A oil pipe could not work like that as most oil pipes work by gravity.

They are in fact grease pipes fed by grease nipples in about the same position. You can see it quite well in the photo below, the nipples are the round dots above the pipe work.

Ah! OK. That makes sense.
