Re: Honeycomb soldering boards

I also got one of the rectangular ones and a pack of the steel pins. These latter are tapered and while they are an adequate (but not tight) fit when pushed right down into the holes, they're then rather short. As I wanted some longer pins I found some 1.2mm diameter piano wire which fits reasonably...

Thanks Andrew, that's very useful. That's also an interesting resistance soldering set-up you have there.

Re: Honeycomb soldering boards

As I understand it, the pins that cooksongold sell are for use with the small round boards, not the larger honeycomb boards that Gareth links to. As the holes in the two types of board are apparently different sizes, can anyone confirm that these pins are a decent fit in the large honeycomb boards? DT

Re: 16T Weathering Experiments

Also, in general terms, I find that (for a dry wagon interior, as opposed to one that has been sitting out in the rain), you can get wonderfully subtle variations with the judicious use of weathering powders. This also applies to the external parts of the wagon as well, of course, especially parts ...

Re: Turnout construction - Question here please.

I've very pleased to say that, without any consultation with Tony, I use virtually the same method as he does for soldering dropper wires to the undersides of rails. The only real difference is that I have used multistrand copper wire, but as Tony says that is effectively fused solid when the solder...

Re: Turnout construction - Question here please.

Yes, re-inforcing plastic chaired pointwork with a few soldered sleepers concentrates stresses caused by thermal expansion and leads to failures so would suggest that you need Philip's or Enigma's mix for safety. But isn't that exactly what Philip's and Paul's mix does - reinforcing plastic chaired...

That may be the theory. But in practice, has anyone ever found this to be a problem?

Re: Turnout construction - Question here please.

As far as I know there are three geberally acknowledge methods of making P4 track. One of these involves PCB sleepers. I shan't say anything more on that as I've never used it as I don't really like the appearance of PCB sleepers. The there's ply and rivet which I have used to make a variety of trac...

Re: Turnout construction - Question here please.

I haven't used Masokits chairs bacause I don't use PCB sleepers, and never have. I've always thought that timber sleepers are visually more appealing. So for many years I used ply and rivet and tried to pretend that the little blobs of solder on each rivet represented a chair. At the same time, it s...

Re: Turnout construction - Question here please.

Isn't all this ply and rivet construction just a bit old hat now? Surely most people are using Exactoscale or C&L chairs and sticking them directly to the sleepers and I'd certainly like to see a bit more about how that is done, including the positioning of chairs in the more awkward areas and e...

Re: Area Groups and Zoom

I can understand, and support, the Society's reluctance to breach Zoom's T&Cs. So that leaves three choices: first, the Society can pay out several thousand pounds every year to obtain licences for those groups that do not wish to avail themselves of the free version of Zoom. As, IMO, the freee ...

Re: Frame Spacing

The main point is that I'm happy with the way the loco goes, see below slow speed, and don't think it's worth spending more time on it. I certainly don't want to disassemble the gearbox. :) Quite. My mantra is that once something's running well, leave it alone! Efforts in the past to "improve&...

Re: Frame Spacing

Thanks, Julian - mine too is a DJH 439 with Gibson frames, and spacers that seem to be somewhere between P4 and EM in width - I don't know where they came from.

Re: Frame Spacing

Just to add my two pennyworth - I'm sure DaveB that we can all take your word for that, except my first P4 loco was an 0-4-4, where the bogie did not have any sideplay, but was pivoted. So this effectively gave a much longer wheelbase than any likely loco fixed wheelbase. I'd used the spacers suppl...

I must admit that I wouldn't like to try fitting CSBs to an 00 chassis. Even using the slimline gearbox and the slimline hornblocks, I would think it'll still be very fiddly. And even then you're not guaranteed success - One 0-6-0 I built using CSBs ended up seriously front heavy and I was unable to...

Re: Carriage ride height and springing

Just as a matter of interest, you replaced the supplied D&S bogies with some rather complicated fully sprung ones. Did you ever assemble the D&S bogies and, if not, would it be worthwhile building one to see if it gives you the correct ride height?
