Thanks for all the feedback. If any body does come up with a e-mail address for M Breeze please forward to me Thanks He's quite an elderly chap and didn't strike me as an email kind of guy... I could be wrong of course, but I think you probably have to phone him.

Hi everyone back again and will be keeping all posted as to the loco. Have with some others being doing a bit of research into mouldable lagging that will also look scale around steam pipes in cab and also boiler. Will post my results soon.

Hi Bob I write here a broken man. Sunday after noon I was finishing off my side plates for the loco and was machining out the arc's for the bogie and had just finished and took the clamps off to discovery the holes for the stretcher were not in the center. After measuring up every thing only to discovery the pitch between the arc is out my 10 mm. So now I have another piece of material for my scrap bin and have to start again???"""~##

Don't worry Kenn, it happens to all of us - never trust a Model Engineer who doesn't have a scrap box/bin

Hi All As was told to me early on in my career the man who has never made a mistake never made anything. Its only if you keep making the same mistake over and over that there is something wrong.
Regards Paul

That way, you can see any errors before you cut metal. Just a hint from someone who's been there!

Hi all Ken hope everything works out for you one of the cab sides a made I screwed up so do not despair we all do it. Have decided that I am going to scrap the reverser as detailed in martins drawings and look at the one that Chris Vine has made for his Bongo. Whilst away do not think there was another ME in a 1k radius of me just oil wells, drug barons and jungle I started doing some research into mouldable insulation for boilers and pipes especially to look scale. will add it into this thread if anyone is interested or can start a new one. Bob

Hi All I Need some info on the position of the motion plate. M E drawings do not give a position. Some photo show it level with the side plate. Other above and other below???

There has been talk of the bogie being too short, which, scale-wise, is correct. Question is will a bogie, frames and cylinders built to Martin Evans drawing work? If not what mods have builders introduced that do not involve a rebuild?

On checking I find the bogie on Springbok is already 3/8" too long. Since no rush of satisfied users of locos built to the ME drawing materialized I did my own test on a salvaged piece of 30 ft radius track. The result showed about 1/16" clearance to exist. I spoke with one of our club members who has worked on Springbok. He suggested it just about works but suggested machining the front cover down to 1/8" thick. This I have done and I now have about 1/8" clearance. The attached photo shows the result, I machined the outer 10mm down to 3.2mm thick. (The dark centre is the unmachined centre of the cover not the bore!) Attachments:

Be my guest.
I should add that the bogie width across the frames has been increased to take up the axle float inherent in the ME drawings. This Springbok is actually turning into a Baltic tank so I have a second bogie to make. I think I will build to the standard 41/8" inside the frames and add spacers behind the wheels.

isnt 4 1/4" the standard for the inside of frames dimension?

I have just checked the Springbok drawings and 4 1/8" inside 1/8" frames is shown.

From my experience 4.125" is standard if the frames are 1/8 thick for wheels back to back is 4 11/16 ,however if my memory is right , Stirling had 4 3/16" between frames .There are other arrangements , for example the engine I am building , the wheels BB is 4 9/16 " and between frames is 4 1/8 , it is strange but the axle boxes sink in horns by 1/16" to make up the difference . there is no rule on this each engine may differ . I hope this helps .
