Geoff I still do not see the NEED for such dramatic stiffening. I too come from an engineering career albeit our structures were very flexible compared to...
Bob, I regard your offering as the most significant email of the year so far. What you are explaining is something that is little understood. Current...
I'm following this thread with interest, but I'm not trying to add to it except one point. Usually we make the chassis, and get it running, then the body,...
Roy Rushed off to look at "LNWR Portrayed" but unfortunately nothing there. I also looked through my book on LNWR signals hoping one may be lurking in the ...
Hi Bob, I just reversed the hornblock and placed them inside the chassis and used jury axles/springs to hold in place as normal. I'd say they are no different...
John, Just one more thought on a temporary or very short run mould, push your master into a blob of bath sealant. Frank [Non-text portions of this message have...
Thank you Brian I'm not sure how long it would take to illustrate this but you and others feel it worthwhile... I don't think you need to worry about the...
... Paraffin wax also works. I have made a master and poured wax around it to get the mould. In a pinch I have also melted down wax crayons. Bruce Wilson ...
There was an interesting article in Model Railway News mid '60's on home casting using Araldite, from memory I don't recall how the moulds were made. Mick...
Steve I suspect you may have fitted the hornguide the wrong way round. The flange goes to the outside of the frames. Thai's the way I interpreted it and fitted...
Hi Bob Thanks for your efforts. I too have looked through my various LNWR books to no avail. Strange when they weren't exactly uncommon items. It's for a...
Dear All, After 50 odd years in the structural engineering industry, surely tortion stiffness is far more depedant on the diaphragms and transverse stiffness...
... As a matter of interest, has anyone tried this material to cast or mould? http://www.maplin.co.uk/Free_UK_Delivery/Polymorph_35511/Polymorph_35511.htm ...
Jas Exactly. My point is that torsional stiffness doesn't really matter. You do need a section that is stiff in lateral bending. As dependant on the frame ...

Hi Bob, I'll have the cables in the car bagged ready to go. The h/blocks were reversed on the inside JUST whilst fixing the h/guide, hence the flange allows...

Hi Bob, et al, I see little or no point in thickening the mane longitudinal members as this will add little to either the tortional or lateral stiffness....
