Re: Trouble with old SM3s

That stuff has transformed my SM3s entirely. The meter shows virtually no resistance across the conatcts.

Many thanks again, Brian.

Re: 2-10-0 loco

Can't deny, a 4-10-0 would've been very nice. Here's the Bulgarian version:

Re: Trouble with old SM3s

Many thanks for your feedback and advice, gentlemen. Stese, I'm attaching a picture of the SM3 seen from underneath, as it were, which shows how awkward these contacts are to get to, even when not mounted on the underside of the baseboard and wired in. Harsh or not, emery didn't do much good. Brian'...

Trouble with old SM3s

After singing the praises of the old H&M SM3 point motors, I have to confess I'm now having quite a problem with them. These SM3s are attached to the underside of the various baseboards, which were stashed in a cold, damp, uninsulated attic for quite a few years. The boards and tracks survived this ...

Re: RSR new layout.

The tracks at the "northern" end of the station have been laid and the ends at the board joins lined up. The "southern" end is missing a few uncouplers, which had to come out when I reconfigured the boards to solve the problem of points divided over the joins. Trouble is, I seem to have mislaid them...

Re: RSR new layout.

Most of the new part of the layout is now installed, so I decided to put the old part back together and start wiring up. All that will then be needed is the last couple of new boards, which will be tailored if need be to fit. There were three locations on the old layout where I hadn't taken care ove...

Re: RSR new layout.

The southern half of the headshunt and continuous run tracks is laid, wired up and tested under power, albeit with a lashup. Many of the wires and connectors have had to be installed above board. These will need to be disguised during the scenery phase. The next stage is the installation of the cont...

Re: Soldering steel rail.

Hmm, quite a lot's been going on since I was last at the Forum. Baker's fluid nostaliga etc. Those were the days. Many thanks again for Tricky Dicky's advice, and Forfarian's. I'm clearly going to have to look for another soldering iron, one that has its own good store of heat. I fear my pointy one ...

Re: Soldering steel rail.

Thank you for your feedback, Richard. Sorry to be a bit slow here. I am coming more and more to the realisation that what's needed for work that drains the heat (like steel rail) is a bit that's big enough to have heat in reserve. As I mentioned, the iron I have has a fine-pointed bit which apparent...
