Hello OP, Quite a few 450v 75uf capacitors located UK, delivery 2/3 days on ebay (2nd class mail transit times). Item no: 143605111682 (located NI) will give you suitable search terms. (Restrict your 'item location' to UK only'.) I note that the same vendor also supplies 25uf. Maybe also search +++ 450v Motor Capacitor ++++ & similar broad-brush terms (on ebay) as well to give you general stockists & also don't forget to check if suitable supplier has a non-ebay webpage for better pricing. As an aside, the 'item description' explains that 'start capacitor = 250v & run capacitor = 450v'. But suggest that you replace both with 450v. Oh; and the item description gives the dimensions so you can check that the item will fit if space is tight! Regards, Phil

Depending on valve mating surface condition and overall length of the valve spindle can you p'raps slip a suitably sized 'O-ring' down the shaft of the valve and onto the valve face?

Nice presentation of pics and locos. I was interested that there were no 'Dutch Railways' locos though. Are drawings not available or difficult to obtain? And, are there commercial drawings for 'Gea' the O&K locomotive? I ask as my inference from your write-up is that there are.

Had a look around your website too: Very nice T3 & accompanying wagons too. Looks great with your very well disguised driving-wagon.

timjenkins31 was last on this forum 19 hours ago at time of writing; i.e. 11 hours prior to your last posting. Maybe PM him on here as well as hoping that he spots this thread and responds directly to you.

¡Olé!
What a great result, both operationally and visually. Even the wheel design chosen by your daughter fits the design well.
I recall that your original intention was to design in such a way that as many parts as possible could be 'contracted out' for construction by third-parties with you assembling the precision parts. Were you able to achieve this or did you have to undertake significant machining yourself? I recall, and you refer to it above, that you purchased a small mill to carry-out fettling operations, was this tooling sufficient to complete the machine?
Regards, Phil

Tim made some clupet rings for me ( Rufford Steam Works) for a 5" gauge steam loco and they are excellent. Can recommend as a satisfied customer (& with no other link whatsoever, commercial or otherwise). Phil.

Hi MIke, (Pending Jason's response) ..... As & when it suits you may find using this calculator to establish the approx. weight of any components useful. I think that Jason's 4.5 kg. estimate is 'hollow' as that webpage estimates just under 5 kg for a hollow structure as drawn in your first posting in this thread. Phil

Hello Mike,
Really impressive work and a tribute to your skills.
I'm afraid that I have a question about the two levers on your steam turret: Are they 'pull' to open, or 'push' to open, please? And what sort of angle do they move through? (I ask as I will be facing fitting similar valves sometime in the future.)
Regards,
Phil

Hello John, further to Dave's post immediately above -> you want Aluminium Potassium Sulphate available from ebay; or from your preferred supplier of course. You must have the 'aluminium' version as 'Potassium Sulphate' is also available and both are commonly called 'alum'. However, without the Aluminium it will not work for your use. I read on here somewhere that Aluminium Potassium Sulphate is also known as 'Potash Alum', so that gives you an alternative search-term. Flood the area containing the broken tap by immersion or building a small 'coffer-dam' around the area and if possible keep hot. It is very slow (a matter of days not hours, despite the video linked to below!) but will work. You can always try and gently dig 'bits' out during the process to try and speed things up. I found this relevant video on youtube. But a search is sure to turn-up others with more detail. Regards, Phil

Martyn,
Do you have any idea of pricing(s) and likely availability dates that you are prepared to disclose yet?
Regards, Phil

Hello Phil (H),
To answer the question that you have posted in 'General Chat' under subject-heading 'Posting Photos' I recommend that you ask a moderator to shift this thread to the main 'General Chat' section of the board or alternatively start a new 'Simplex build' thread there as more will read it. The layout and visual presentation of the forum on-screen may mean that some (many?) do not come-down to this relative forum backwater so will miss postings under this heading.
Looking forward to your build description,
Phil (R)

3/16" x 3/32" is a standard size in US, example. Phil.

I have fitted shrink-fit steel tyres on cast iron centres down to 5 1/2" diameter wheel centres no problem. Steel rims (approx.) 1/2" thick (i.e. difference between inner and outer diameters). Just needs accurate machining and confident action during final fitting of rims. I fitted using 1 thou + 1.5 thou per inch diameter interference. I heated the rims using a gas (propane) flame until they were 'very hot'= just below faint red and they were a loose fit upon sliding over the hubs but tightened really well upon (natural) cooling and seem solid without any other retention/security methods. Final fitting must be done with confidence and promptly as heat-loss and conduction is fairly rapid.
In my experience one could go significantly smaller - however, the smaller the diameters the less forgiving of 'errors' in machining/measuring and any hesitations whatsoever in final fitting. The smaller the mass of the parts the quicker the heat-loss and heat transfer.
Regards, Phil

Another 'pro': Steel tyres have greater adhesion over cast-iron tyres.

Here is direct link. Shawki, is that chimney-top spark deflector prototypical or added by you? It certainly flies around! Phil Addendum: gwrfan types far faster than me!

Excellent memory 'millman'! The thread referred-to is h ere. Posting by phil1001 on Feb 2nd 2012 at 9:00PM is relevant posting. Click on associated attachment to access pdf. Attachment shows that closest you can get is 19.84tpi (1.28mm pitch) using 32T on Spindle drive and 25T on Leadscrew. 25T & 20T respectively give you 20.32tpi (1.25mm pitch) Phil
