First time scratch building a locomotive.

I have done a lot more since I last was on here.

After getting the running plate done and valance, l started on the cab front and back made out of N/S 0.015in, I cut two pieces out to roughly the size I then soldered the two together, then used my marker pen and covered the one side, I then marked it out and the the windows, I used a piecing saw to cut the shape out and useing a smal drill for the windows and work up to a larger drill and finished of with a tapered broach the get to the right size and then slit the apart. Marked out the running plate for the front and back of the cab.

I used 0.015in N/S for the boiler, and the boiler is 21mm diameter I had to work out the width to cut. I then used my rolling bars till the two ends meet then soldered together then made up two end bits for ethere ends of the boiler, on one end I drilled a hole and soldered a 8ba nut for a 8ba bolt to temporarily attach to the cab front.  Then I cut a piece for the smokebox and wrap and soldered it around one end. I then used 0.010in brass for the top layer of the smokebox i punched a row of rivits down one end again wrapped in it around and soldered in place. I then made up a plate for the smokebox front that had to be shaped for the sandbox front.

Next was the tank, cab and bunker sides in which I made as one. I cut two bits on 0.015in N/S soldered them together blackened one side then marked out the sides including the tank fronts. I cut to shape, I had to solder a bit of N/S to go at the inside bottom of the the door way on one side peace to strengthen the side at the door way as it was a bit to thin at the top. I then slit the two sides and soldered another bit of N/S at the bottom of the door way. I then mark the tank front and scored then bend to shape and cut out to round the boiler.

You've done well rolling the boiler from .015" n/s, I use .010" brass for boilers, I find n/s doesn't roll nearly as well.

Hi Michael.   I have the GW models rolling bars. I just adjust the bars little at a time and let it roll off the roller at each end, roll it back on then a just it a little.

Looking great Ray and as I said earlier when we spoke, 'you've done well with this kit'!

 

 

Yes it's a kit from bits of nothing but sheets of N/S and Brass and marking out, cutting out the shaps soldering them together. Yes it's a different type of kit it called scratch building.

I am sure I haven't done this before Doilum. I have built a few brass kits, the Simon Bolton books have helped me. 

You're welcome Ray. That's a fantastic build!

M7 Scratch Build update.

I soldered the sides on that I made earlier. I then made up the back of the coal bunker, it's got that curl at the top, I made that by scoring the metal every 1mm from top down to approx 4mm, then I used a 3mm drill and the top of the metal in a vice and bend the metal to shape so it fits in the curve then soldered in place. Next step is the top of the tanks I cut them out of 0.015in N/S soldered the two together and filled to size I then split them up and soldered them in place. Next I made up the hand rails, I marked out the hand rails knobs and drilled the holes glued the knobs in place. The rail I used 0.40 N/S wire, I always have a job with the front of the hand rails to get the bends in the right place, thread two hand rails knobs that go to the front and thread the two sides into the side rail knobs, then glue the two rail knobs into the holes on the front of the smokebox. 

That's the game of play at the moment.

It's been some time since I put an update on this M7 Scratch built.

Lots of small bits added. The roof I made from 010.00in brass, put through my rolling bars to get the shape of the roof and soldered 1mm x1mm L shape brass around the ege of the roof, then I used T shape brass across the centre of the roof. I also made it so it can be removed held in place by brass wire pushing against the sides to hold it in place. The injectors I made from copper electric wire, I had to sand paper the varnish off so I could solder into a brass tube. Then I held it in a vice so I can drill two holes into the brass tube and soldered  two pieces of copper wire into the holes for the live steam pipe and the over flow pipe, there is a photo of this below. The pipe work will have to be cut to size to fit into place by solder. The tank stabilised pipe is from brass pipe and tubing soldered into place, there was a lot of solder used and filled to shape, then soldered under the cab and front end the is the where the water pipe goes for the injectors. The buffers are from Markits and the lamp irons are Marin Finnley.  In just need the part I ordered from P.D.K such as the tank filler lids the tank inspection lids and the boiler front, and also the sandbox from Mudmagnet model's then I think it is ready for the paint shop.

I am also looking at making a Drummond 700 class in which I have to thank Dave Taylor for give me the drawings and some photos.

That is looking really good Ray.

I am a bit too young to remember them in real life on my local line to Exmouth.

But I have always felt in pictures they looked like pretty big no nonsense locos,

which you have captured very well.

 

Hopefully one day I can see it on Feltham Road, 

 

cheers

Thank you. I am hopping to put it on Feltham Road when ever the exhibitions can come back.

The scratch build of the M7, I am now see the end of its build. I have got the bits I ordered from P D K yesterday, the boiler front and the tank filler lids, I did ask for the tank inspection plates but he had none in stock so I made them from headcode discs and used my pin punch to make the bolts heads around the edge, I then glue them in place. I intend to to put a sound decoder in her with a led for the Firebox flicker, so I drilled a hole in the Firebox doors to take the led but that was not in line with the hole in the bulkhead so I had to cut a Rabat in the back of the boiler front so I can run the cable up and through the hole in the bulkhead. Now it's time for the paint shop, I used Hallfords Gray etched premier. I wish to thank Richard Slate of Mudmagnet model's for 3D printing the sandbox.

My finished scratch built M7. I have done quite a bit from the last time I posted on here. I sprayed Hallfords Gray ectch premier then a gloss black. Then the tranfers, I used Fox transfers they do them for a M7 but is this set they don't do the lining for the valance so I ordered them form Modelmasters, I have been waiting for the transfers for nearly a month from Modelmasters, poor Jim has not been to good and having having a operation on his eye as well, but it was worth the wait. The decoder is a Zimo Mx648 with a You Choos M7 sound, it comes with the Western House pump.on function 11 and it also comes on as a recycle but as I did not put the pump on I asked if he could turn recycle off. I fitted two small sugar cube speakers and a very small stay alive taped to the decoder and I tucked it into the boiler and I also fitted a Led in the firebox. I very much enjoyed building this and being it's my first scratch build. As I was waiting for the lining transfers I made a start on a Drumond 700 tender.

Well done Ray, a really great job and the painting/lining has been applied really well. So I gather you are building a Drummond 700 class next? Good luck.

 

Kind regards,

Hi Richard.   Yes I have made a start on the tender. but having a problem getting some of the white metal parts.  so if you know were I can get hold of them?

That is something to be very proud of - I look forward to your next project !

Hi Barclay.

Yes I am very pleased the way it has turn out. I did have a few moment with building it but I got over that. Thank you for your response.

Hi Ray,

 

Which parts are missing Ray? Not much to a 700 class tender.

 

Kind regards,
