|Thread: Loctite and quartering wheels|
Heating the joint (gently!) to a little over 250 degrees C will release the grip of the loctite. Any residue can be easily cleaned-off.
I would persevere with 638 as it is ideal for your intended use, and your first two attempts went well. Confidence and speed will win-out.

|Thread: Rex Tingley Valveless design|
The principle of method of functioning is that the piston runs within an inner cylinder which itself slides back and forth within an outer cylinder. The inner cylinder has ports drilled in it which at certain positions of travel line-up with ports in the outer cylinder.
The inner cylinder position relative to the outer cylinder is changed by the piston sliding back and forth as the travel of the piston is longer than the length of the inner cylinder.
To call the engine 'valveless' is misleading (I suggest) as it is actually a sleeve-valve engine with the movement of the sleeve driven by the piston travel at each end of the stroke.

|Thread: Lathe DRO|
Jim Smith 8 - I have also sent you a Private Message.
Thanks for the link Jason. In the absence of a suitable optical scale I have already ordered a (small) magnetic scale, albeit not one of the tape versions that you linked too.
I was unsure about mounting the self-adhesive tape, and a previous enquiry on here (on a different thread) failed to turn-up any experience of use. I can always give the tape a try if I cannot fit the magnetic 'bar' in a way that suits me.
Thanks & regards,
I have been playing about with fitting an optical scale in a similar restricted location and the smallest optical scale that I could find is the KA200 series (sometimes written KA-200), the scale of which is 16 x 16 mm with a reading head 14 x 14 mm (total height with clearances 32mm). It is available in the standard 5um and, from Germany, reading to 1um.
Should you find something smaller please post and let us know!
Next smallest optical scale I could find is the KA500 series with a scale dimension 18 mm wide x 20mm high with a reading head 14 mm wide x 20mm high; total height with clearances 43mm.
|Thread: 5 " AJAX|
Maybe worth having a look on Model Engineering Clearing House forum where a couple of posters have or had these locos, others are familiar with them as they were (are?!) a popular club locomotive, and I recall that one regular poster (in South Africa) is currently restoring one.
|Thread: Thompstone Engine|
Jason, and others, of course,
Re: period castings for Thompstone Engine;:
Model Engineer, Vol VI, No.69, March 15 1902, page 144, under heading 'Amateurs Supplies', text reads:
Model Horizontal Engine Castings
Readers of The Model Engineer will hardly need an introduction to the work of Mr S. L. Thompstone, some of it already having been published in these pages. A neat list, which he is issuing post free, on application, illustrates a model horizontal engine which is made in two sizes. Those who require castings of this type of engine should make application to Mr Thompstone, Nelson Street, Broughton, Manchester.
End of text.
|Thread: Loco wheel profile chatter|
LBSC's mandrel for turning locomotive wheels was fitted as follows:
"Chuck an odd casting or disc of metal a little smaller than the back of the wheel ..... recessing at the middle for about 1/32 in depth and 1 in. or so diameter" (quote from 'Virginia' notes, but similar wording appears for other builds) and then fitted with a mandrel which was subsequently turned to appropriate diameter. Thus the mandrel was principally for centering the wheel which was fully supported by the 'odd casting' or 'disc of metal' held in the chuck. The nut on the end of the mandrel was used to pull the wheel back into firm contact with the ad-hoc faceplate.
|Thread: How on earth do I build this boiler for my Fire King ?|
On the same page that Jason linked to above with the drawings (link here again for convenience), there is also a link to a build description, here. It is immediately to the right of the drawings' link.
The build is described in French, however the photo's are international, and even if you don't speak French an on-line translator and some imagination will assist & maybe clarify. The boiler is described and pictured on the lower part of page 2 of the build description.
|Thread: Copper tube?|
M-Machine list it.
|Thread: Two or three axis DRO|
If you go to ebay and 'search' ************* you will find what George was trying to link to. I think.
I'll try and See C of C

|Thread: Wahya construction series|
Thank you for the response Luker. Hopefully you will be able to relax without the concerns of filming etc., and you will be able to enjoy your beautiful locomotive still more.
It is a real tribute to your skills and approach and looks and sounds really good.
I found your 'pressure-gauge' article very interesting too. Following your example I am looking to source a couple of suitable pressure-gauges (10bar) from ebay (or similar) to experiment with.
I've enjoyed the Wahya series too. And the locomotive looks great and runs well. But I note that you don't seem to notch the valve gear up (??).
|Thread: 00 Gauge Live Steam Locomotives|
If you search +++ sherwood +++ in this Model Engineer index you will find quite a few articles of his covering construction of 00 (and still smaller) live steam locomotives from the late 50's referenced.
|Thread: Micro rivets|
You can get rivets down to 1mm diameteer from Sapphire Rivets in steel, stainless steel, aluminium (& alloy), nickel silver, brass, copper, bronze, monel, in a variety of head-forms 'over the counter'.
No need to try exotic sources down to 1mm diameter shaft; unless you want to, of course!
|Thread: Butch - can it come back to life?|
If you get stuck or would like advice at any time then it may be worth having a look on Model Engineering Clearing House forum as one regular poster ('Doug' ) there has restored (his thread on the topic includes many descriptions photos) and runs a Butch, and another is building 'Twin Sisters' which is a very similar design. From memory a few of the posters have had experience of 'Butch' as it used to be a popular and rugged club loco'.
The forum is very locomotive oriented.

|Thread: Finding a good home for my Dad's engine|
So, thanks for the info'.
Looks like you have a Nigerian Railways 'River' Class locomotive as built by Vulcan foundry in the UK and others elsewhere.
Your father built this at 1" to the foot scale. So it makes an interesting, meaty, and somewhat unusual model.
If you want to get an idea of price/value then you might want to browse Station Road Steam to get an idea of prices. There are other dealers too of course who may merit a browse. When you know 'how much you would like', then, as mentioned by others above, a 'free' advert' on here or Model Engineering Clearing House may allow you to 'test the water' as you appear reluctant to list on ebay. The lack of any (test) documentation for the boiler will depress the value - dealers sell with boiler documentation. Knowing what the model is etc., will enable you to get a better price.
Please keep us (me!) posted.

As to what the source locomotive design may be:
The plans that you show in your last photograph are not directly relevant to this model. It is unlikely that your model is of a French prototype (used in France) as it has a 'pilot' ('cowcatcher' ) which were not (customarily) used in Europe. However, it may be a French design used in the French colonies or areas of influence.
The photograph that you uploaded with three photographs of real locomotives may be more relevant as there are striking similarities (albeit with some stark differences) between the photos and the model. Maybe these photos were taken in Australia?? The signals are distinctive and may aid identification. The paperwork in that photograph may shed some light on your father's inspiration as there is some commentary about the design of valve-gear and I can also see some documentation referring to French 'pacifics'. There is also the corner of some drawings of connecting rods (??) or similar visible, these may indicate the source design.
Your father's model is of a 'Mikado' rather than a 'pacific'. So, any references to pacifics indicate inspiration rather than the specific model.
The model may be a free-lance design incorporating some of your father's ideas rather than a strict copy of a particular type of locomotive.
Model Engineering Clearing House has a good number of Australian based locomotive enthusiasts and one of them may have a few ideas about the model.

|Thread: VAT changes post Brexit|
I contacted my MP, Greg Hands (Con. Hammersmith & Fulham) pointing out that some European companies were refusing to sell to the UK as they regarded the new HMRC VAT requirements too onerous for the revenue involved. I further pointed-out that there was no apparent way for small and artisanal producers to undertake a simplified procedure.
Mr Hand's admin' support appear to be unaware of this 'hitch' and my observations have been forwarded to Jesse Norman (MP, Hereford & South Herefordshire), Financial Secretary to the Treasury for his consideration.
