If you are going to make any indentations into the boiler fabric I would have thought the best place would be on the firebox wrapper along the foundation ring. Just saying.

All the more reason to consider migration to a Linux distro and Open Source applications. It gives those into programming to keep an eye on what it's internals are doing.

If it happens to be an interference engine I'd not take the risk of a home-brew belt.

Many thanks for all the suggestions. I'm sure the solution is there.

Not so much a thread but I've been asked to make some single layer coil formers for an amateur radio application using my clunky old S7. To prevent the wire moving I'm proposing to machine a shallow semi-circular groove at a similar pitch to the wire diameter. In this case the insulated wire is 1.3mm O/D. I've got a pretty comprehensive collection of change wheels including a 127 tooth. Accepting I mustn't open the half nuts, can anyone suggest a change wheel set-up to cut that pitch or very slightly coarser..

It'll never work properly until the laughing shaft is connected to the giggling pin.

I haven't yet made patterns for the UPT but I have for the VDH. (I have a spare set of castings here at the moment). Gating should not be anything to worry about. The foundry will sort that out for you, in fact, from personal/professional experience I've found no two foundries work alike.

Not strictly correct.The 9Fs along with the other larger BR standards had the frames centred over the horns. A clear example may be seen where the horns can be seen being welded centrally into the frames of Hengist at http://www.72010-hengist.org/hengist-components/frames?start=40

This feature was also common to DoG (71000), the Brits (70XXX) and Clans (72XXX)

Apologies for highjacking the thread but can someone recommend the best place/price for circa 200 x 3/16" snap head ali rivets?

Significantly quicker than try to spark it out.

Would a good rub with something like solvol autosol help?

Would it be possible to get it to run with WINE?

Warning heeded after spending far longer there than I really wanted to.

Schoolboy snigger,

It says a lot but just don't get me started on the politics of our UK home railways.

Malcolm Martin, Ken?

The reason why I asked one C spanner or two was because I need two (different sizes) for the spindle of my mill.

By all means stretch it slightly as you apply it but I'd not recommend stretching it that far. It sounds like any advice you received to use it that way was trying to avoid the use of the PVC tape over-wrap to apply pressure.

Continued to make some overly complex brass fittings to go into a GWR Bow-end composite carriage being restored on the SVR.
