SimonD’s workbench

I have girded my loins, whatever.


This is the offending cylinder


Not too much of a fight, happily, but..,



The solder joint on this slide at has failed. I don’t think it was heavily loaded as it was still aligned. Very frustrating



Ready to reassemble. Friday.

It’s been a frustrating weekend. I fixed the slidebar without too much bad language, and having fitted the decoder, set about tuning it. This was not successful because there was another “snick”. Once per rev. Not obviously related to crankpin clearances or quartering. Lots of trials got me precisely nowhere, so after a trying day at work I said something that might have sounded like “rowlocks” and took it to bits.

This led to the sacrifice of the brake hangers which are a bit fragile. And the chassis paint has taken a battering too…

I have washed the gearbox in IPA and relubricated it, stripped the axles & their bearings, cleaned them, and reassembled it, and the snick has gone.

Unfortunately we now have too much sideplay, but it runs as smoothly as it should.

So now the rebuild begins.



Bloody thing

Simon,

It seems it's going to be a battle of wits, to the bitter end.

It sounds like the “ Snick “ might have been some foreign body trapped between the gears, being that the snick was once each full rotation. Good shout as it sounds like you have solved the issue. Onwards and upwards.…

Martyn.

I’ve fitted a couple of sideplay filling washers, given it a few more runs up and down the front siding on PD Loco and it’s now as sweet as it should be.

we have the super-duper new Bambu labs printer at work, I might kick off a dozen brake hangers of each hand with integral shoes in PETG just to see if it will do them justice. I’ve got more resin ones and can print more as needed, but the PETG ones will be far tougher. We have an 0.2mm nozzle for the Bambu, but the 0.4 is fitted at the moment, and production takes priority over the boss’ hobbies…
