Cheers, it's ironic that the reason I have found such strong glues is because I spent years sticking bits of photoetch brass together whilst actively putting off learning how to solder properly. Now I've stopped sticking bits of brass together (otherwise known as military model-making) I'm getting quite good at soldering. I've got some nifty tricks for knocking up things out of plastic and metal, though, as long as they're not very large.

So nice to see outrageous over-specification like that Keysight meter. It's the antithesis of marketing bollocks. Quality!

I've dabbled a bit in the etched brass in the past myself, albeit with the trains. Great fun. Soldering it (and white metal!) is a dick compared to electronics work so I'm not surprised it put you off.

While I'm waiting for bits, I finally got round to sorting out the time-base knob on the 2465B. It had been sheared off where the grub screw bit on the shaft. I drilled the shaft, pinned it with a length of brass micro-tube which got the ends squished flat and was bonded in with vinyl superglue (PC-80). I drilled out a length of styrene rod , heated the squished end of the pin a little and glued that on with the PC-80 too. That's the white section. It was much easier this way than dismantling the front panel and replacing the shaft, and it seems plenty strong enough. A tap on the end gives a single, solid response from the shaft as a whole. I'm happy, even if it does show up the bromine on the older plastic a bit.

Interesting alternative to my own similar repair using splice & solder technique a few weeks ago...

BD139 - I never had the guts to tackle a train but always admired the brass ones, they look beautiful in natural brass and very realistic when painted. Even doing smaller stuff I found the sense of accomplishment thing a very rare occurrence compared to electronics. Finished models only numbered two to five in a good year, and then I always felt I could have done certain things better. I get a bigger buzz every time I track down an issue and fix it (still rare, but not AS rare).

Mnem- Very nice scarf join! Did that not take a lot of heat? I'm lucky the shafts on the 24XX's are plastic.... my soldering is not that good yet.

bd139:
Yeah know how that feels.  I had a pile of unbuilt kits floating around when I was into that. I completed an RJH class 37. That took me most of a year (1994-1995 autumn/winter/spring) and way too much money :(
