G'day Ian
Are the cylinders castings? Where did you get them and the wheels?
Is the boiler a Smithies?
Regards, Ian

Cylinders are castings, the plans and castings came from Ernest Winter www.ejwinter.com.au. The boiler is an ianmac design as the boiler in the plans really didn't seem suitable. The boiler has 7 flues and will use a metho burner of some design when complete. The cylinder bore on plans was 9mm but this has been increased to 16mm for a number of reasons. tooling was one and the boiler was also increased. With any luck over the next two weekends the running gear on the right hand side will be completely finished. The left had side only has connecting rods no cylinders either. The cylinder was botched so i have silver brazed a new piece of gun metal into the existing casting which i will mill down and turn to size. The chimney also needs some work i will do that once its in place. The two pipes coming from the boiler are water in and steam out. The plans showed that the steam pipe was to be braised into the back of the boiler but this made no sense because as soon as the loco would move the water would obviously rock and the steam pipe would be full of water. I am really keen to see the bug*er work on compressed air. Ian

THE ENGINE RAN ON AIR! it didn't go first up just needed to fiddle with a few things here and there and then did it go or what! SWMBO even made a visit to the workshop to see what all the commotion was about. "looks good she said" she actually meant it thought What a feeling as you see hours of work come to life! I am well an truly hooked. This weekend ill will be having a decent crack at the cylinders on the other side. Sat there watching those wheels tick over for half an hour. Simple things i guess!

All i need is more time in that workshop.........To think that the wife wants to spend time with me! "Stay away from me temptess.....you are keeping me away from my work" She has been very good though.......wonder what will happen when she sees that the 38 is just a "little" bigger..... ;D

Some more work has been done. The running gear on the right hand side is 99% complete. Just needs to be made prettier. permanent nuts and bolts fitted. Smoke box had chimney fitted and smoke box door. Hinges work well and i now need to complete the bits and pieces so that it cam be held closed. www.flickcabin.com/sessions/da39a3ee5e6b4b0d3255bfef95601890afd80709/Smoke box.jpg[/img] this photos shows the smoke box placed on the frame waiting to be bolted into place. www.flickcabin.com/sessions/da39a3ee5e6b4b0d3255bfef95601890afd80709/chimney and smokebox.jpg[/img] Botched the LH cylinder. For some stupid reason i was leaning on the hand wheel and slipped when doing the port face. All was not lost. Machined out the full steam port area and then cut two strips and sweat them into place. filed down the stips to the top of the port face and now i just need to sand the port face down on a mirror . I also botched the piston rod cylinder cover on the same day. stupid me. I had machined to correct size then used center drill first so that i could pass a 1/8th drill bit through. Than i was thinking to myself (not out loud so Murphy could hear) jeez I'm getting good at this model engineering stuff. Put a size 20 drill in chuck and moved it up to the job. The tail stock was a bit stiff so i loosened off the locking bolt so that i could move the tail stock. I then moved it a bit to far the job caught the drill and passed it completely through. ;D Rather than look at the safety aspect of what went wrong i have focused of the real cause, Murphy, so I now ware AL-foil on my head to stop him reading my thoughts.

Yesterday i drilled the holes for the rivets and placed some of the rivets into the smoke box Tedious work. this took about 3.5 hours, mostly becuase i snapped a few .8mm drills. There are another set of rivets around the smoke box door but i might give those a miss. Anyway it looks good and i am starting to become a rivet counter.

Alrighty More progress has been made. Cylinders on the LHS has been fitted along with the main drive rod. Cylinder cover and steam chest has been machined its just waiting for the correct position of the valve travel to be set before its all screwed together. Its really moving along at this point so in a few weekends i think i could quite safely say that it could be steamed up and given a wiz around the track...........Really quite proud of myself getting this far. Seemed to be quite the project but bit by bit if all comes together and once you see things moving you realize that most of the hard work has been done you get another boost which will hopefully will carry me through to completion. I have noticed that as my skill has improved bits that passed QA 7 months ago have been remachined or done again. This was the case for the channel in the drive rods. To grove them previously i used a 2mm slitting saw (NASTY). I found a woodruff cutter for a few dollars and set about cutting a proper channel. Looks much better! www.gscalemad.co.uk/forum/uploads/post-30-1219377509.jpg[/img]

G'day Ian
Is that a new boiler? With the hog back it is really starting to look like a 36.
Regards, Ian

I think I found the problem: it are video's. The photo's are fine.
My take is that Ian made a wrapper for the boiler. That dual tapered boiler is rather special.
