Flying Scotsman Triang Body Screw

[richard]

Does anyone know of a source for the screw that attaches the chassis to the body on a Triang Flying Scotsman?
Everyone seems to be out of stock except for a guy on EBay in Australia who doesn't ship internationally due to problems in the past.

Alternatively, the specification: I'm assuming it is BA? (BA screws are unusual in the US - I can't go to Lowes say and get a mixed box to try them, but at least I can get them from other sources if I know what I'm looking for)


Yes another scale has been added to the house. I've been given some Hornby OO. Most looks to be about 20 years old (B12 from the East Anglian set, a Virgin HST, Mallard,etc), but there's also an old Triang Flying Scotsman. It has seen better days but should be repairable - missing screw, broken footplate (can be glued), worn boiler bands.

Is this the R398 Flying Scotsman? If so the service sheet at http://www.hornbyguide.com/service_shee ... sheetid=63 may help; it suggests that the screw you need is part number S1023. And in that case, looks like suitable spares may be obtained here: https://www.hornbytriangspareparts.co.u ... ecords=999. Tri-ang certainly did use BA screws for some purposes - S1023 looks like a 6BA or 8BA screw to me - probably the latter.

Thanks - ordered. Not sure of the R number but yes S1023 - I did look it up but didn't have the number handy.

"Hornby Triang Spare Parts" didn't show up with Google and searching a recent Railway Modeller that I picked up when I was over!

Well I've been beaten to it...

I'd just checked the sorry remains of my T-H Scotsman and found a 6BA Cheesehead screwed into a phos-bronze helix that used to be moulded into the cab floor until it pulled out! Should you have difficulty getting the screw, even though you have apparently managed to order one, the necessary 6BA is 6.5mm long on the threaded portion, 8.5mm overall including the head, and I do have a spare 6BA screw that would do the job if you find you need it - albeit with a domed head rather than CHD, and it would need to be shortened.

Typically, I have loads of other 6BA screws too, all with less suitable CSK heads!

Thanks Atlantic. 6BA. That is also useful for anyone else with this question!

I did have a quick look on Amazon US and they didn't have any BA screws - only taps & dies! So it would have probably been an import through EBay, or a screw specialist.

The arrival OO had a mixed response from the domestic authorities - we now have 5 different scales/gauges (counting US & UK N as the same):

- Z. Someone gave us a secondhand Miniclub starter kit.
- N ("little trains" - my son does enjoy these)
- OO (will definitely be my son's preserve)
- 7mm O (boxed up since my son's arrival but I might restart later this year)
- Lionel 3 rail O ("Christmas train")

When I was re-arranging my office earlier this year, I was tempted to add a small Z tail-chaser on top of a shelf, but decided the space would be better used by plants.

Screws arrived and fit.
Adding power to the motor, it shows signs of motion, but there's enough corrosion on the driving wheels that I might put the project to one side.

In other news we have a loop + two sidings set up with Kato track. Everything else is running in some form or another, but I'll probably add another track feed (ordered). All the locos needed at least a little oil. Some were really clagged up with dirt on their wheels. Strangest repair was an 08 (circa 1980) which simply shorted the track out. Turned out a track pin had somehow become lodged between one of the wheels and the body!

A Virgin HST had power issues but mostly fixed with wheel cleaning and making the trailer wheels more free running. Still the Ringfield bogie is a bit anaemic imho. Might replace the traction wheels next time I send an order in to the UK. (the power bogie also has a missing lug from the frame but appears to run fine)

The Triang Thompsons also have pizza cutter wheels - so I might replace those as well. They are tending to pick the Kato frogs.

I have note 6BA = US 4-40; 8BA = US 2-56
There are tables of equivalents out there
