Hi
Started this thread on the other channel (RM) Unfortunately due to changes have found it difficult to continue, so I've jumped ship. I will carry on where I left off, if you wish to see the early stuff it's under Kit & Scratch building Finney 7 Drummond.
I have been on this site following some of your builds, but this is my first thread on WT.

The chassis is just about complete with a few small bits of detailing to do. I have had it running and it runs very well, so well happy.

Took a while to figure out how and where to fit the pick up scrapers, but it all seems to work.

The front reservoir for the push-pull I had to scratch build, as the one from Laurie Griffin was a bit on the small side.

Haven't worked out how to do the moving stuff, so a still pic on track.

You will have to take my word on the fact it ran oh so well.

Couple more pics.

Gosh that was easy, think I've found a new home.

Hi Pete, nice to see you posting on WT!

As far as moving pictures are concerned, they are not hosted here. You need to post to Youtube and provide a link.

Thanks Guys. I feel warmth and loved.

Thanks Adrian, I shall try your suggestion.

Been working on the boiler back. I needed to do something with the sight glasses, just don't look right being all brass.
I found a company who make 2mm sq clear bar. They come in 500mm lengths and cost just under £13.00 (most of the cost is in postage)
I cut out the centre bit of brass leaving a flange top and bottom, then stuck a peace of rod between.

I drilled the ends so I could solder copper wire for the pipes. Above was attempt one, as I had forgotten to solder the pipes first. Didn't want to melt the acrylic. DER

I then had to make the marking to the rear of the glass. I found a pic (I have found only three pics of the boiler back. Two on the net and the other from the book "From nine elms to waterloo") On one from the net I could just about make out dots (4 across and 8 down) and a red level line.
I used a 4H pencil lead sharpened to a point for the dots. I used my loupes to see with.

I then glued them on using R/C Modellers Canopy glue as it tries clear. PVA didn't work.DSC_1224.JPG

I think they work. I painted the back first so I don't have to paint the copper. I shall use an Epoxy to stick all in place.

But first I need to work out how the pull-push mech works. Thanks to a photo Steph from Finney 7 had sent on to me, I had something to go on.
Unfortunately it doesn't seem to want to down load, so here's my pics of my attempt from his pic.

I know it looks very Heath Robinson, and by the way Steph's photo was from another model which he saw at an exhibition, no more details.
Peter Cross also has sent me a photo of his idea of the mech.
Sorry about the blue tac, just needed to hold the regulator in place for measurements.

If anyone has any more info then please do share.

Thanks Pete

Hi Pete.

Whilst not modelling in 7mm, I am very much a fan of the M7. This is looking very nice indeed. The weathering in particular is just right.

Hello Pete, and welcome.

You may find these helpful:

30053 Cab.  Eastleigh Works Yard.  23 May 1965.  Personal Collection.  Final.  Photo Brian Dale.jpg

This is a photo of taken by me of 30053 as withdrawn in Eastleigh Works Yard on 23rd May 1965, ie before preservation. This may be of help in locating some of the bits on the backhead, although regrettably it shows no real detail of the sight glasses.

65462.  Sheringham.  12 May 1968 (2).  FINAL.  Photo by Brian Dale.jpg
This is 65462 at Sheringham shortly after going in to preservation but before restoration, again photographed by me. It's doubtful whether there have been many, if any changes to the cab layout this early. A decent view of the sight glasses but I'm uncertain whether this would be typical of all locos at the time. Doubtless there are members here who can comment.....

...the book "From nine elms to waterloo"...

Aah, so it does exist then. I've been trying to get a copy for many years with no luck (either out of stock or the wrong book supplied - it shares it's ISBN with a children's encyclopedia!)

Dad, I wish I'd seen that photo a very long time ago. That's the clearest shot I've ever seen of the in-cab pull-push gear. Shows how wrong we've all got it...

:mad: Sorry about that....you only had to ask, and you usually do when you want a prototype photo.

I had assumed the control linkage went from the shaft to the regulator lever. So also wrong. Can't quite work out what what it does do.

Aah - I think I can. :)

The regulator handle isn't the conventional shape, but has a socket (and perhaps a bayonet clip) to take an arm (which is missing - as usual) from an intermediate lever, on the right hand side of the backhead. It's this intermediate lever which is connected to the rod passing over the top of the tank. There's a short link connecting the two. It allows there to be an easily-removable linkage from the regulator control cylinder to the regulator itself that doesn't stick out into the cab. To keep the links and levers close to the cab backhead the valves for the steam heat and reverser needs to be avoided; it would be in the way if the link was direct.

I'd quite like to see a photo of the same backhead from the other side of the cab as there could just be an adjustment to the link on the far side of the cab. But now I'm being picky, this has been incredibly useful.

Dave,

Tried that, and Abebooks as well. Both Amazon and Abebooks seem to build their book listings around the ISBN and I think the local charity shop has enough copies of the blasted children's encyclopedia. For a while they were averaging about 1 a month. I've had enough of the funny looks.

If I see a copy of "Nine Elms to Waterloo" I shall pick it up. I'd like to buy it from the Drummond Society or Swanage Railway, but haven't got anything out of them either...

I do appreciate the thought though! :thumbs:

Every search I've tried by the ISBN10 or ISBN13 number only ever comes up with 'Nine Elms to Waterloo' as the book with that reference. I'm game for a laugh so I've ordered a copy. We'll see what arrives. One thing we're not short of locally is charity shops. I can donate a dozen copies at least without visiting the same one twice!

Pete, nice to have you join WT as well. Your M7 build is looking good and you will find lots of guidance and help here, the 7mm forum of choice in my opinion.
