43xx part 1 - chassis with CSB

In between lurching from crisis to crisis at work, I've been making progress with the 43xx chassis. Or is that as respite from the crisis at work...
The kit is of Mitchell vintage and must be fairly old since the label on the box has it supplied by Slaters. That's going back a bit. The prototype will be 5311, since I've a very nice photo of it at Wells.
Anyhow, I mentioned on some other post that I've made a start on the High Level hornblocks. After that I made up the coupling rods, making sure to allow plenty of solder to try and disguise the layered construction. I then prepared the frames by drilling the CSB fulcrum holes using the High Level jig, then removing the cut outs. After some deliberation I also removed the springs, with the intention of fixing these to some form of keeper plate. I folded up the frame spacers but surprisingly had to fettle these before they'd fit into the chassis frames. With everything nice and square and using a combination of my Avonside jig and some good old fashioned tapered axles, got everything soldered up. I had to do one of the hornblocks twice as curiously I allowed it to drift off from its position.
The CSB fulcrums are WD handrail knobs and after fitting these in the pre-drilled holes, I was pleased that the additional holes I drilled in the spacers to let the wire pass through are in the right places. I temporarily put some 11 thou guitar wire through and everything seems to line up nicely. After taking a few snaps, the horn blocks have been dropped out and everything given a good scrub clean. I'm quite pleased with how it's going.

I have never done a csb chassis, but I quite fancy having a go at some point. I'm interested to see how it all works out .

Mitchell designed kits are a joy to build. Finished one of these 5 years ago and I still have to put the wheels in it...a rather timely reminder! Built the Mitchell tender to go with it...hated putting in the flares.

I think they're the future (to mis- quote Peter Kay).

Oh dear! It's my first. I've a couple more to do. Finesse wise, I've only built one Finney to date and that was a pleasure.

Forgive me for asking but what is CSB John Lewsey

No worries!

Continuous Springy Beams. The horn blocks and chassis is sprung using a run of steel guitar wire which you can make out in the photos

More information on the CLAG website here

Could I ask whose chassis jig your using as my attempt at a home made jig has not worked out too well?

 

Wooops, Just re-read your post and you do mention whose jig your using...

 

Anyway it does look nice and clean work, I still need the practice.
