Re: Driving wheel axle material

What's the ID? And if you don't already have it, it might be a good idea to get some hard steel rod of an appropriate diameter to go up it!

Incidentally, when I mentioned that the stuff I have was bendy, I'm talking about the 500mm length, not individual axles!

Re: Driving wheel axle material

With respect, Derek, I think you've misunderstood the method used to make split axles with the 1/8" tube. It quite genuinely is pretty simple and, unlike the Branchlines or Society split axles, requires no lathe, no multiple sections, and no jig, and a straight axle is virtually guaranteed. Hav...

Re: Driving wheel axle material

The primary reason that I stuck something on the forum rather than sending a private message was so that others could see that we're moving towards a "critical mass" of orders. The minimum order is only £45 worth ex. VAT, so including my own requirements we're already virtually there. The...

Re: Driving wheel axle material

Thanks, everyone. I'll wait a few more days to see if there are any more takers, and then place an order. As I'm sure you'll appreciate, I'll have to add postage at cost to everything I send out. I'm getting the tube from Coopers Needleworks. They have a huge range of sizes, both fractional and metr...

Re: Driving wheel axle material

I have now managed to locate a source of 1/8" stainless steel tube. I have measured a sample and it is spot-on. The Inside diameter is 2.57mm so this would seem ideal for split axles using the Bill Bedford method as described above. The same company also supplies 2mm stainless steel tube with a...

Rust on wheels

Does anyone know of an effective way of dealing with rust patches that appear on steel-tyred Gibson driving wheels? I can remove most of it with the ubiquitous fibreglass pen, but suspect that that is not curing the problem, merely postponing it.

Re: Power supply

I don't know if it's relevant, but from the Pictroller (handheld) instructions:
"If a high current (>750mA) is detected, the output is turned off and the overload LED lights."

Re: Power supply

I didn't see any mention of amps on the instructions for the handheld unit, only for the more complex panel mounted unit. It may therefore also be worthwhile checking with Malcolm about the ampage requirement for the handheld just in case that's different. He might also be able to recommend a suitab...

Re: Power supply

The Pictroller instructions suggest a 14-18v AC requirement. Gaugemaster do a number of relatively inexpensive open construction transformers and if you really need as much as 1.5 amps, their T2 Model will give you 1 x 18v AC output at up to 2.5 amps for less than £20. Gaugemaster do suggest that th...

Re: LMS Steam at the end of the LMS era

Beautifully constructed locos - I wouldn't even know where to begin with that valve gear! Not wishing to be picky, especially as I'm still putting off painting any of my locos, but on my monitor at least 6103 looks very grey!

Re: Small diversion - High Level Mineral 0-4-0

Do we have any other contenders? I'm currently building a High Level Hudswell-Clarke 0-4-0. When I can work out how to get the wheels on properly (I know, silly but true and surprisingly difficult) I'll try adding some weight. As we've just had some roofing work done I've got plently of lead but I'...

Re: Tim V's workbench

Thanks for that, Bryan, very interesting. I looked rather longingly at the tubing you found on ebay, but as you say it is 3.3mm OD, ie 0.13 inches, fractionally but crucially bigger than the 0.125 inches required for most 4mm axles. Not having a lathe, I do not think that i could reduce its diameter...

Re: Tim V's workbench

I note that High Level's Slimliner gearbox is 6.3mm wide at the point of the driven axle. Given that the centre section of the Society's split axles are 10mm wide, this may be the answer. I think I shall acquire one at S4North and give it a shot.

Thanks, Gordon. I've in fact got some of these, but haven't used then on my latest loco. The centre section of the S4 Stores axle is 10.00mm wide. The High level gearbox I am using is 9.75mm wide. I can't, I'm afraid, guarantee the necessary precision to ensure that the live section of the axle will...

Of course it did - two, in fact. Adams Brewery and G.E Cook & Sons. Both, sadly, now closed, so research at once loses some of its appeal. :(

Re: request for gauge/scale information

I will retire hopefully gracefully until tomorrow, No need, surely - Keith's come up with the right answer, hasn't he? 3ft 6ins is 1066.8mm. The track gauge of the model is 21.5mm. Divide 1066.8 by 21.5 and you come up with 49.6 which is, of course, as near as dammit 1:50. http://en.wikipedia.org/w...
