Thank you Malcolm! This thread is getting better with every post :D Appreciate your encouragement and advice. You have answered my questions and I shall dither no more :thumbup: Just one confirmation/clarification, if you don't mind, please - you are talking about "...place the springs partially int...

Hi, over 30 years I have built about 400 locos. and that's why your advice is so valuable! Thank you :thumbright: ... The only commercial models (40 off) that were sprung were Balwin 4-6-0 tank locos... Not a good project from the commercial side ... It sort of answers your question .. It sort of d...

...Hi, I was interested to see the article about the Hunslets I built years ago. ... Thank you very much for your detailed reply Malcolm!! In particular, I appreciate the photos :thumbleft: When I started this thread I didn't expect, how interesting it would be :) Question - are your axleboxes spru...

OK, I am beginning to understand... :thumbright: The original design intent was for the 14mm pin to be short of the top of axlebox openning in the frame, so that if an axlebox went all the way to the top of it's travel on the weak spring, it would bottom on on the frame, not on the pin. Makes sense ...

Hi Tony, I remain confused by your descriptions of springing arrangement for Swanage Lilla. Perhaps it is because Swanage design differs from Ross Harrison's design? See below, how he originally intended it: https://lh3.googleusercontent.com/YLs-Z8mxur49nD-K1sWHhO77MlLX7zfWuj2_mbhLrmiLpBNJnnznT0oROv...

Many thanks Tony :thumbright: I always thought that LBSC's idea of brazing frames to buffer beams made for much more rigid and stable loco, so I guess Ross's design (particularly when "poorly constructed") was likely to be flimsy... I guess you have improved matters by getting better axlebox springs...

Thank you Tony! That's very interesting. I would love to know more about ( - better to learn from other people's mistakes :D ): ...poor chassis design... Pleased to hear, that she now : ...runs very nicely... I presume that 3/8" dia cylinder (when compared with RH 9/16" ??) wasn't "the" problem? The...

bit of an addendum... info that came up on Yahoo group: https://groups.yahoo.com/neo/groups/Steammodelloco16mm/conversations/messages/34514 and for those who are not members: ...The Ross Harrison Lilla builds into quite a good representation of the prototype. A small batch to this design was built b...

Lovely indeed
Am I correct in thinking that it is 1:22.5 running on 45mm gauge (prototype 1000mm gauge)?

...That's more like watchmaking than modelling....... yeah :) It was just a feasibility study and I am beginning to think 7/8" version on 45mm track might be more interesting proposition. This would btw make it comparable to LBSC's Tich but on narrow gauge instead standard gauge :thumbright: ..Thes...

An interesting letter on the subject of full working Stephenson gear in 32mm gauge Hunslet, by Malcolm Wright of Wrightscale in Sept 1994 issue of Garden Rail: https://lh3.googleusercontent.com/AFRZKwmzFbelfZrmjoLokrQHTNNcK0_yGTTX2KDPIQ18cwNQ6OYnlVr_1x83econa4mow8Ard0nAwyUz658xGSKKtny-Sjfym0KUT8If6x...

...The real quarry Hunslets don't have very long eccentric rods either, as the inside motion bracket doesn't leave much space... Thank you for the link to these photos :thumbleft: That confirms that what I am doing is reasonably "prototypical" ...For comparison, the eccentric rods in that photo of ...

Well... it might be doable indeed :) Modelled first approximation and the layout looks like this: https://lh3.googleusercontent.com/2_C6-03oy6yglTwv95aUBAnfCL9GEg3x5LKMJUQ5C3OXZp4ZtDx5KvbznqrU2Hs7wIJj9p8P4Yb8dGJcuE4pbZ0lgES-nu3gfkTv1Wbs9IHkXZtRPPTDVSw1w-zQtX2WEFyDFFi00gc=w2400 It's all based on gaug...

Hmmm, interesting. Like you, I also suspect it has problems, having seen the drawing... basically you have full forward and full backward with nothing in between, but this is not really much different to most of the "simplified" valve gears used in 16mm locos? ...It looks like the width of the slot...

Very tidy work
Copper will be more difficult to solder because it conducts the heat away very well.
