Standard 4MT build - Scale 7


Recommended Posts

I wonder if those beautiful etches could be shot down to 4mm scale.......

 

Why not ask MOK? If they receive enough expressions of interest they might be persuaded. They are asking for EOIs for a Mucky Duck - 7mm scale of course :P - so they appear to be open to suggestions.

Latest update - moving on to the front steps and footplate. The front steps main etch have the lower step etched in which then just needs folding up. There is then a half etched overlay which is held in place by the tabs from the middle step, this needed a little bit of filing around the bottom step to get it to fit.

There is also all the webbing behind the step, each bit fits neatly bit but I decided to clean up the soldering after each one as I wasn't sure that I could get in to clean up once the step and all the webs were fitted.

To complete the footplate running board there is a thin etch to form the sides of the dropping footplate which needs to be bent into an S shape to fit.

This has various half edge slots to locate it on the main running board, however on the top running board by the S-shape it's rather flat and square edged, where as further back the edge is rolled over. To keep replicate this rolled edge I used a polished bradel at about a 45 angle to roll the half etched edge on main footplate before fitting the side etch - hopefully you can see the polished edge around the S-shape on this photo.

So finally fitted in and cleaned up.

So this is the current state of the front footplate, still lots of detailing required, handrails, steps, lubricators etc.

The 4MT is 29.1mm over the frames and the dummy frames are 30.36mm wide so there is a little step from the dummy frames to the chassis, fortunately it will be hidden behind the cylinders. The Jinty I've just finished is 29.5mm over the frames. Even at 29.5mm it has a good bit of sideplay but having said that I don't have anything to run them on at the moment so I don't know how it'll work out. I suppose it depends where you want to run them. I suppose it depends a bit on the wheelbase as well, the 4MT is 7' 7" - 7' 9" whereas the Jinty is 8' 0" - 8' 6". I suppose I'll have to get round to building some track or getting to a meeting where I can run them and find out how they really cope! Any more updates on the L1 then?

I think that Bob Essery used the full size (4'1 1/2" inside approx 4'4" outside so 30.3mm) scaled down on his 0-6-0T but had to reduce the flange thickness on the middle set of wheels and gauge widening on anything less than about 8'. IIRC it was in Bedside Backtrack.

 

OzzyO.

A while back I promised to add some photo's of my 5" gauge 4mt tank for comparison, well after a few long days and completing a few necessities (such as repairing the internet!) I thought it was about time I got round to fulfilling my promise!

 

First things first I have to state that no of the work you're about to see is mine, I do however fully intend to finish her though! I always joke that this is my retirement project so if true i've got another 40 years of prepping in the meantime! Fingers crossed I will actually make some progress sooner than that, but i'm not commiting to a completion date just yet! :D

 

The model is being built to Doug Hewson's drawings (basically scaled works drawings) and encorporating his castings. It is designed to how all fittings working as per the full size, including atomisers, rocking grate and steam ejector, a bit of an improvement over the basic live steam models designed by LBSC in the 60's.

 

Anyway, I apologise for the quality of the photo's as they were taken on the phone in less than ideal light level's however I hope they are of interest!

I'm sure there are lots of recognisable components between the two scales! I must conclude this post with a huge admiration for what Adrian's achieving, this really is an awsome build! Looking forward to the next updates.

 

Best Wishes

That's fantastic Paul...! 5" is something I tried to get into about 10 years back, but I was just too young, and didn't have the skill or tools to do it. One day I'll have something on the Schedule at a Gilling Mainline event!

 

Hijack over 10-4..

Spacer strip supplied by the S7 group gives 29.96mm over frames using 0.028" frames.

 

However 30.4mm has been used for S7 locos.

Managed to grab a few hours modelling time this morning so finished off replacing the bolts holding the spring hangers on with a 12BA stud and nut, which fits in much better with the casting.

post-91-0-06758000-1300623310_thumb.jpg

 

 

I then moved onto making a start on the cylinders. These are quite hefty brass castings with a thin etched overlay as a wrapper. Quite entertaining and needing a couple of attempts to get it right.

post-91-0-99958100-1300623329_thumb.jpg

 

 

I then started adding some of the detailing, the front covers, snifting valve, covers, core plugs and safety valves. The front covers have a distinctive flat which needed to filed on the castings. So the current state of play is this.

Crikey - nearly 2 months since my last posting - seems like only yesterday. However I've been rather busy and the modelling is a spare time hobby. After a long holiday at the beginning of April I cobbled together a few S7 items as I'd volunteered to help out on the S7 stand at the York Exhibition. Any visitors on the Saturday would have seen me there with the current progress on the 4MT.

post-91-0-43592400-1305763106_thumb.jpg

 

Since then the weather has been too nice to be stuck indoors modelling so not much progress has been made. However last weekend the inclement weather meant I could hide away in my work room for a few hours and make a bit of progress. However I'm stuck on a couple of items, I've still to work out a satisfactory arrangement for springing the rear bogie, as supplied in the kit it is a rigid unit. Secondly is all the motion on the chassis. Most of it is brass castings, whilst exquisite in it's detail it's the wrong colour!!! Sorry but steel valve gear should look like steel so my current dilema is whether to tin the castings to look like steel or fabricate new items from steel.

 

So in the usual style I turned to something else instead - and made a start on the rear bunker. These are the parts required.

 

post-91-0-35344200-1305763125_thumb.jpg

 

 

The first step was folding up and assembling the bunker doors.

 

post-91-0-31961800-1305763138_thumb.jpg

 

 

The rear of the bunker has a few holes missing from the etch, this is all detailed in the instructions but does need a few extra holes drilling. So out with the marker pen, square and odd leg calipers.

 

post-91-0-56946500-1305763157_thumb.jpg

 

Once drilled the rear detailing is started with steps and handrails.

 

post-91-0-75355400-1305763173_thumb.jpg

 

Finally mated with the rear cab spectacle plate.

Thanks for that, hopefully a small update next week, although not much progress to report as I've been busy with other things*. I do like the 8F, especially as there is a photo of one stabled at Tewkesbury shed, and I noticed that the kit has been withdrawn pending upgrades, so given the number of positive responses for the original kit then I think the new one must be on the essential list.

 

* kids have just started kayaking so we've been busy with training for our 1* paddling assessment, also I've just upgraded the software used on my website to make life easier. Rather than losing the details in the thread I'm slowly copying the 4MT build details with a few more photo's and details over to my website, http://cherryclan.co...standard-4.html.

Now would that be the Std. 4 Mogul, or the 9F? (he said, fantasising wildly about MOK doing a 4mm scale 9F body and tender to go with the Bradwell chassis.....)

It'll be the standard mogul, but I wouldn't bet my shirt on it being ready, I've been waiting for the Armstrong since last September when it was supposed to be released. Latest is that it should be ready for Guildex :unsure: maybe, possibly.

 

One thing's for certain, when it's finally released it will be worth waiting for.

Not the one I was thinking about, it's bigger than the mogul but not as big as the 9F. Same number of wheels as the 9F!

Current production plans for MOK are Standard 4 76xxx, which should be available now, followed by the Armstrong and then the LMS derived 43xxx Mogul, with the 9F expected early 2012. At present the LMS 2-6-4T may well follow the 9F which is what Dave Sharp informed me of in a recent e-mail.

Any more progress on this kit?

Sod all recently, too many other things to do over the summer to be honest. However I'd volunteered to man the Scale7 stand at the Wigan show and whilst looking at my various projects I realised that I'd hardly touched it since the York Show at Easter. However at Wigan I got a few requests to get cracking on it, and the the quality of the show was inspirational so I've dusted off the workbench and made a start again.

 

Starting with a few more bits to do on the bunker before turning to the tanks. On the cab doorway there is a small plate to solder on with the handrail knobs, it also has a half etched plate with some rivet detail. As supplied the half etched plate has a collar on around the hole for the handrail knob as indicated in the photo below.

post-91-0-46852800-1323903408.jpg

 

However the instructions suggest opening up the hole carefully with a drill to remove the collar. I didn't fancy drilling it with the thin sheet however a few minutes with a broach had the desired effect.

post-91-0-89147300-1323903418.jpg

 

I'm glad I did because once soldered up the base of the handrail knob seated nicely in the doorway.

post-91-0-56331300-1323903443_thumb.jpg

 

A cruel closeup but it shows the result. The only problem is that the photo has highlighted the lack of texture on the hinges on the backplate. I can't leave it like that so that's going need a bit more detailing.
