Snapshot Update – Alan’s Model Engineering In Thailand Projects
New Big Lathe And Milling Machine Installed In The Workshop
Below is a photo of the KINWA CH 430 1100 Lathe and the ARGO Vertical Turret Milling Machine 3VH installed in my model engineering workshop in our retirement house here in Pakchong (Pak Chong), Thailand.
The walls of the workshop are now complete awaiting painting. To the right that big opening is a roller-shutter door doing what it was intended to – to let the light in.
The workshop looks a bit cluttered and it is as the single and three phase power distribution is being installed. That coil of black cable is the three phase power cable for the lathe and mill. Here are a couple of exteriors photos showing the walls:-
Above, the opening at the end is a roller-shutter door to allow access for machine tools, benches and eventually a half-size model steam traction engine to pass through!
The photo above is at the other end of the workshop and is simply a window to match the other two on this elevation. You can only see the window frame – the shutters and security bars yet to be fitted.
The Stuart Turner Victoria Steam Engine Model
I had been struggling to make some silly little parts – the guidebar supports and spacers, on my other lathe – a combined lathe and milling machine actually.. They are only 1/4″ dia and 1/4″ and 3/8″ long respectively but they all have to be exactly the same length.
I’m on trial 3 now and have used up all the Stuart Turner supplied 1/4″ round BMS stock and most of a 12″ piece I happened to have.
Eventually I found out how to do it and they are all exactly the same length withing half a thou:-
Here are the finished spacers (two types):-
Buying Steel Bar
I mentioned above that I was fast running out of 1/4″ bright steel bar. I needed some angle steel to fill in some gaps around one of the roller-shutter doors so off I went to get some from the local steel merchant Ying Jaleaum. Whilst buying the angle iron I bought a selection of round steel rod. I didn’t really know what I was buying I just pointed to each of the smaller size rods and asked for 2 m of it.
Here are some photos of my haul back home:-
The next photo is a close-up of the round steel bar. it is all bright mild steel (BMS) as we call it and on the receipt it is called “plao kaao” in Thai which translates to ‘axle shaft white’. So now you know what to ask for.
Above the round bright steel I bought in Pakchong (Pak Chong), Thailand.
The sizes are interesting. I was wondering whether they would be metric or imperial. top-to-bottom, the sizes as declared on the receipt and as I measured them are:-
|Receipt Size||Measured Size|
|11 mm||10.97 mm|
|5/16″||0.314″ = oversize by 0.0015″|
The 11 mm bar although it looks like black bar is in fact bright steel.
What else is interesting is how many of the bars were exactly to the imperial diameter. In the UK BMS is traditionally undersize so that a BMS rod will never be a close fit in a reamed hole.
The next photo is a close up of the steel angle. I have included this because the steel is so precise and clean with sharp corners and the marking is very clear. Not at all the rough angle iron I am used to back in the UK.
