Re: CSBs... on the strength of handrail knobs

Many thanks for your comments Russ, and I can confirm that I took some care with positioning the opposed pairs of tubes, placing each fabricated pair against an end stop and filing back any remnant overlap of one tube beyond the other. A scriber was then set and used to mark the end positions of eac...

Re: CSBs... on the strength of handrail knobs

Keith, Will, Thanks both, Keith - yes, absolute agreement about problem of using thinner wire -in principal. However, in last post I was intending comparison between CSB and 'my' set up using same wire thickness in both cases. That said, I understand why a 23mm gap rather than 16mm might be needed t...

Russ, Keith, gents, Back from a bracing day on Longstone Edge, so brain rather clearer than last night post-wedding reception (not mine). Russ - many thanks for 'doing the math' as they say across the Pond, interesting to see where the greatest loadings fall. I will take that away into a corner to c...

Hello Russ,

No, S&D 7F has 6ft+5ft 6ins+6ft, versus 8F having 5ft 6ins+5ft 6ins+6ft3ins.

Re: CSBs... on the strength of handrail knobs

Will - and via you, Ted? Many thanks for the feedback on this. I take Ted's point about the 'set' at the end of the anchor, and yours about deformation of 0.2mm wire. 81 rests on wire of ca 0.3mm (Poss 0.33?) and so far no sign of deformation of that when I have withdrawn it to inspect. I may well n...

Re: CSBs... on the strength of handrail knobs

Zeb, and CLAG colleagues, Ouch! I am rather mortified that my article has prompted the destruction of at least one perfectly good handrail knob, and rather guilty at the thought of the cumulative time spent on a) discussing and b) testing. Not my intention at all. I must re-read my script, but my co...

Brass preparation for painting

Can someone remind me please, if the use of cream cleaners such as Jif, Cif etc to prepare etched brass for painting is a bad idea? I note Alan Goodwillie has used referred to the use of Vim on his Starting in P4 thread, and have a suspicion that additives in the other cleaners I mention above will ...

Re: Loco Suspension, fitting CSBs

Many thanks also for your explanation at Manchester Show of the application of the fulcrum physics to locating the handrail knobs. Having gone as far...

Re: Hornblocks choices.

Allan, I had exactly that issue when using the HL axleboxes in a GIbson P4 chassis. Admittedly I had shaved the P4 spacers a bit to allow more room for sideplay on curves, but I think it would have been tight even otherwise. I obtained clearance for a wide HL gearbox (ie one with a grub screw fixing...

Re: Hornblocks choices.

Hello again Simon, Good man! I found that removal of the machining burrs either side of the slit gave me a fit, admittedly tight, on the etched guides, and that this soon eased with application of a mix of oil and Brasso, to give a silky sliding fit. I would avoid sanding anything - you will be crea...

Re: Hornblocks choices.

Hi Simon, I know what you mean - I found them awkward at first, but am now a complete convert. What may not be obvious, if you do not have use of a craft magnifier light, is that the machining leaves ridges at the intersection of surfaces, including the bore for the axle. Not evident at a cursory gl...

Re: Fishplate conundrum

Interesting indeed - especially Martin's reference to GWR usage of two-bolt fishplates. I have been surprised to encounter photos of Somerset and Dorset track on the Bath extension relaid by the LMS with 60ft rails, presumably during the 30s, which only had two-bolt fishplates. This was the era of t...
