On Brian Wilson's Eric (and few other designs I looked at) steam pipe is quoted as 1/8" dia tube, but nobody ever mentions the wall thickness... :oops: I can get 1/8" copper tubing in following SWG - 27, 26, 24, 22, 20 (or for metric guys from 0.4mm to 0.8mm wall thickness). Which size of ...

thank you guys,
so it is aluminium body ...
I was aware about aluminium and plastic ones, but was hoping to find steel body ones.
It will be interesting to see how will aluminium perform long term in this particular application.

Where did you find M3 heim/ball joint
or are you making it yourself as well
when I tried to source some, the smallest I could find in steel was M5 or M6
anything smaller was either plastic or aluminium...

:D It took two attempts to get pony truck frame right ... and the second time I put (almost) as much time into making a fixture that held everything for silver soldering as I did into making the bits for the frame :thumbup: but I got it right in the end - if you look closely at the photos you will s...

Thank you Dazza! Any praise coming from you, is particularly nice indeed :thumbright: It would have been great to have mouldings from Mike in NZ for both pony truck frame and axleboxes. Maybe next time... For now it is just rough, coarse representation of swing link truck in the prototype, but it wi...

Thank you ttg

btw - more updates from the restoration of full size Fowler at Steam Workshop :

What is expensive ? Hard for me to answer... [/b] I was hoping you'd indicate the price you've paid for these beauties so that we can all individually decide whether it is something for us as well (we all have different pain treshhold :mrgreen: ), but if you cannot (or do not want to) go public wit...

These castings are excellent
How prohibitively expensive are they?
Do you have to make shrinkage allowances in your CAD model or does Mike do it?
What other materials apart from white bronze can he produce these castings?

It turned out to be rather pleasurable Graeme :D The parting was aided by syringing-in cutting oil using the trusty lubricator draining syringe. And, with an 18tpi hacksaw blade, the 1" was easy to cut, again with cutting oil.... +1 on that :thumbleft: I cut all my wheels with hacksaw and it's...

I am referring to the same document, but I haven't got the latest version (mine is 2006), so it might be that it has changed...
Section 2.5 (in 2006 version) is Coal Fired Boilers

Yes, I am aware about the moves to create separate code.

...For clarity, to which boiler code are you referring? in UK - The Boiler Test Code 2018: 6.5 Boiler water feed arrangements shall be by at least two independent means (two of each, or a combination of, hand pump, injector, mechanical pump, etc.). A single boiler inlet with two check valves is acc...

Yes, just been through Riverdale webpage. The arguments (with which I totally agree) against the use of axle pump are very well explained by Brian Wilson in this August 2014 article in "16mm Today" magazine: https://www.riverdale-loco.com/Today.pdf So I guess, you are right - it is accepta...

...There were articles in AME magazine in 2017, they did thermal modeling of what happens in a coal fired wet leg boiler when run dry ...I saw this in action on the loco at my local ME club run... How does it square with the boiler code which requires you to have two independent sources of feedwate...

Something slightly different (i.e. no update, although I am making progress :thumbright: ) Here is one of the original, Leeds build Aussie Fowlers that made it's way back to UK: https://youtu.be/_IOnLpnF11E She is in "Steam Workshop": https://www.steamworkshop.co.uk/portfolio/2-fowler-1634...

...I have now tested with a servo tester ... and the jitter isn't there; can't see a way of testing for the crosstalk, but the rx is starting to look very much like the culprit.... Yes, I think you have narrowed down the problem. If it was servo problem it would also be a problem with servo tester....

Have you done anything to the RX antenna? Does it happen with servos and receiver just connected on the bench (i.e. outside of the loco). It's not likely to be faulty servo. It is not a normal behaviour. It matters - if it is that bad with transmitter only few feet away from the receiver, imagine wh...

You are doing such a nice job, put a grate in and burn the black stuff. Thank you. I would like to do it indeed :thumbright: but this particular model would need too much butchery to rear of the cab to permit easy access for the shovel. Plus, adding axle pump at this stage would be a bit of PITA I ...

Spent couple of days pondering how to fit the burner and pony truck in the space available and here is what I came up with: https://live.staticflickr.com/65535/49172533201_1ddb776374_b.jpg It's shown with LH frame removed for clarity. Red block secured with two bolts to frame stretcher is both burne...

Sounds like I got away with it :mrgreen: Cleaned axle holes in the wheels with wet & dry, soaked the wheels in acetone for two days, put them in a dishwasher and after preparing them as normal loctited using Loctite 638. Job done - they are solid :thumbup: Next is the rear trailing pony truck, t...
