Len,
Excellent recovery. A lot of work for you but certainly worth the effort. Well done.

I have now put on the Chassis detail overlay.
While I am posting, how do I put the index on the front of the post so I can go to the last post and add to more posts?

I have tied that but it made no difference, I don't now if you need to do something else.

make sure you roll the boiler the right way round not inside out, like some idiot did

I’ve been trying to find the time to finish off a guide on thread marks. Currently it’s in draft but I’ll try to make the effort to publish it, hopefully that will help.

Thank-you Adrian.

I have got to this stage of adding the dummy hornguides, but if it is battery operated do I need to do this?

If you are not picking power up from the track then no. The hole is to pass a wire through to the pick-up.

I thought so. Thanks Mark.

I agree with Ken, I would fit them, for the added detail. Irrespective of whether they are actually used as they should be.

I think Len was asking if he needed to drill the holes before fitting the dummy horn guides.

It's been 4 months since I last posted (too hot) now it's a bit cooler now (a bit warmer than England though). I am in a bit of a quandary, how do I fit the horn-guied to the chassis (I have a flame, Exctoscale resistance soldering station and a ERSA soldering station) any idea of what to do?

Personally I would lightly tin the rear of the hornguide plate and then sweat it onto the chassis using the ERSA station, only because I don't have an RSU, if you have an RSU then it would do the job just as well. [ I have had 2 RSUs but never found a job for it that I couldn't do with the ERSA station so sold the RSUs - but that's another story!]
Hello Len,
Welcome back...
I have always fixed the big castings with just my trusty Weller WSP 80 irons. I burnish the back of the casting with a brass brush so they are shiny before fitting them though then plenty of flux and ideally a solder which melts around 179°C. I usually use Multicore (now loctite) LMP solder or smart solder for SMD PCB work. These have a 2% silver content. If I ever need any extra heat which is very rare I warm the casting with a hot air gas soldering iron pen or hot air soldering station if I can get access to one. I usually find the castings solder well when I have had to remove them as long as they were clean the solder has flowed under them fine.
Often the biggest problem with large castings is making sure they are flat and flash free so they sit level so it's worth fiddling and fettling them well first.
