Finished doing the handrail knobs on the boiler and soldered boiler together. The smokebox was finally finished after a lot of soldering and filing. Pic shows boiler, smokebox, smokebox door, chimney and dome loosely in position.

Darren, what a great job you are doing. I will never complain about how much I spend on a Loco again!
After viewing this, whatever they charge is fine with me!

Looking good Darren you seem to have got the main body sections pretty much there now the detail parts will take some time now

cheers Brian

Last night I soldered the cab, boiler and smokebox together - this included further filing of the casting marks and seams.  Some final prep required but enough for now. I also filled a corner of the cut-out on the underside of the boiler where I had been a bit overzealous with the saw.

This morning was spent grinding (a lot of grinding - boy does whitemetal clog up the files!!) the underside of the footplate so as to finally seat the chassis (clearance for drivers and motor is woeful). In the end I found that the space was so tight that I had to remove a piece of the worm gear length so as to get it to the footplate to seat properly over it (there was no further space to file out - I would have needed a hole in the floor of the cab...) Pictures dont appear to show much progress but its a bit like wallpaper - the quality of the preparation is just as important as hanging the wallpaper (if you know what I mean)

you are right white metal clogs files to hell the joys of kitmaking adapting things to fit:lol:

But now the chassis is fitted to the body the detailing can begin.

If you done this job this morning what time did you get up?

Brian, believe it or not I was up at 5:30am - I get up at roughly that time everyday during the week and with the bright mornings I cant lie in bed when there are locomotives to built (and the small ben dismantled!!) - I have just got back from the garage as car was in for a recall item replacement and now I am off to have my second breakfast (better watch out or I will crash and burn out on the sofa this afternoon!)

Re the files I have seen various recommendations to clean the whitemetal - blowtorch (not good as this affects the file material itself), wirebrush (limited effect) and the most likely (not tried yet) is using a thick sheet of brass on edge in a vice and going across at an angle..

Spent a long time today track testing motor with body and tender - still not there yet as the bogie wheels seem to be causing a short - need some more grinding inside the footplate as well as there is still some rubbing.

Not to get too disheartened I glued on the dome, chimney and safety valves. Plus buffers on the tender. Used 30 minute epoxy so as to ensure sufficient time to ensure that the items sit right.

This evening I spent some time fettling the coal rails and getting them into the position - this time I used 5 minute epoxy as I needed to have a thicker consistency so that the rail could be set and aligned (it felt like i needed four pairs of hands!)

Yesterday I said I was having a bit of a testing time and was getting quite frustrated as to why the unit was shorting..so here goes after a bit of learning/detective work.

I was satisfied that I had the insulated driving wheels set up and hadnt paid any attention to the bogie wheels and said to myself yesterday, of course I have the bogie wheels the wrong way round (ie non-insulated versus insulated side (as they are very dirty (covered in verdigris (sp?) so I decided to leave today)

I wasnt convinced today after sleeping on it and was concerned that if that was the case with the bogie, then what about the tender wheels?

After review today I now understand that ALL the bogies and tender wheels are insulated at the axle hubs on both sides.

What then? - my suspicion was drawn to the bogie keeper plate extensions and as I had kept the bogie screwed together but deliberately loose (the tender chassis doesnt have that amount of slop available between wheels and chassis), I solved the reason why - see pix below.....solution - place insulating washers in between the wheels and frame plus trim edges of the bogie keeper plates back (oh yes and tighten the bogie frames together properly!)

Areas of sparking on the frame (more cleanup!!) - black ring at the hub of the wheel is the insulation.



 

Two paths for the power to go are shown via the red arrows (circumventing the insulation at the axle hub) when going round curve etc

Glad you found the short problem many hours can be lost looking for problems like that at least with that out of the way you continue with the build

Today, I completed the grinding the insides of the loco and it now rides nice and smooth.

Unfortunately the same cannot be said for the progress on handrail! The nickel silver proved to be the very devil to form for the continuous handrail so I have consulted my reference guides and note that they recommend hard drawn brass wire so I have ordered some as I was getting nowehere fast!

No more now until next weekend...

Ok, finally got the smoke box door on and restarted on the handrail.

Tried alternate brass jewelry wire (too soft), styrene (perfect diameter but not sufficiently robust)

I got the hard drawn brass wire today (perfect!) but it still was a devil to get the continuous handrail in place but its finally completed (i got some handrail knobs instead of the split pins in as well!)

Picture shows it all tied up awaiting final epoxy setting in place (the high temperature today makes it go off quick!)

Where things like the smoke stack and dome meet the body what do you intend to do or use to blend them together properly?

Looks great, Darren. I'm really enjoying following this - and learning things along the way. Keen to see some paint on it.
I remember thinking how good it looked when JohnB [GJG] painted up a metal steamer.  Nothing resembles painted metal as well as painted metal.

Look forward to seeing you back Darren - the time "off" will give you some thinking time about how to get the next bit of that beastie to fit together.

Take care
