I'm going to blame Andy Y. and the Modeller of the day comp. for starting this new thread. http://www.rmweb.co.uk/forum/images/smilies/icon_biggrin.gif http://www.rmweb.co.uk/forum/images/smilies/icon_thumbsup2.gif

Also the lousy weather we are having over Easter.

But it did get me quite eager to do some modelling. So here goes.

This is a London Road Models kit for a LBSCR B4 that I started about a year ago! It's gone together very well so far, the splashers over the front bogie were a bit tricky though.

I've just fitted pick ups to the motor so a test run is in order then we'll go on from there.

I wonder how long this bout of eagerness will continue?

I'll let you know in due course.

Cheers for now.

Very nice indeed a lovely prototype too. What livery will it end up in ?

That's a good question. It will be set in 1908 to run on our club layout. 'Clarendon' so I suppose it will be Stroudley passenger livery. Not to gen'd up on Southern type locos. http://www.rmweb.co.uk/forum/images/smilies/icon_smile.gif

Well, managed to give her a run, actually went better than I expected! Except why is it that given a choice of two wires to connect to the motor you always get them the wrong way round, http://www.rmweb.co.uk/forum/images/smilies/icon_smile.gif Must be one of Murphy's laws.

It needs a lot more weight in it, nice long boiler to fill with lead and also hang the tender so to put weight on to rear drivers.

Here's a photo showing the chassis.

Would be nice to get it looking better for the show at Shepshed in April. I'd better get reading the instructions to remind myself what to do next

Right here's some close up pictures as promised. Better late than never.

First up shows the CSB on the chassis, using the LRM horn blocks (very nice) and just letting the beam rest onto the bearing instead of running through another handrail knob as I think Ted S. suggests. Being LRM horn guides they locate in a slot so the bearings don't wander along the axle. Hopefully that's fairly clear.

Yuk doesn't a close up shot show up all the muck you thought you'd cleaned off http://www.rmweb.co.uk/forum/images/smilies/icon_sad.gif

 

Here's another showing CSB detail, this belongs to an Alan Gibson kit of a LSWR G6. This has got handrail knobs fitted to the top of the bearings.

And just to spoil you here is the completed thing. http://www.rmweb.co.uk/forum/images/smilies/icon_biggrin.gif

Anyway back to the B4.

Next shows the front bogie (upside-down).

It pivots on a central bolt, with the axle beams also pivoting, and a wire soldered across the ends acting like a torsion bar. I think I'm right in saying this is an Alan Sibley design, but no doubt Jol will correct me if I'm wrong.

A bit puzzled about the lack of handrail knob fulcrum; surely you need to have the CSB control the downward movement of the hornblock bearing as well http://www.rmweb.co.uk/forum/images/smilies/icon_question.gif http://www.rmweb.co.uk/forum/images/smilies/icon_what.gif

Hi Horsetan

The lack of handrail knob fulcrum is due to the lacking in width of the mainframe for the third pivot point, out of shot. the beam will deflect up when the weighted body is added, so should give enough room to push down as well. (I hope) I can always file some more off the sides of the horn guides if needed. Some packing on top of the bearing is also an option.
