Rik, Remember that when this was drawn everybody who looked at it would of had many years training and be able to understand the function of the part. If he'd drawn the 'true' or 'apparent' length at both ends in the plan view the lifting arm may of been assembled (or made) incorrectly. The draftsma...

The lifting arms are not horizontal and the plan view shows the 'apparent' length of the rhs arm and the 'true' length on the lhs. The 'true' length between centers is shown at 'J' and the orthogonally correct view at 'F'. The drawing is an assembly drawing and as such would not be used for the part...

I'd be inclined to try something less aggressive than grinding paste, which is after all meant for steel. Autosol or liquid metal polish might be better, even cheap toothpaste, all of which should be easier to remove after a lapping process. For small non ferrous items any surface will do as long as...

The BBC says a 'Steam Engine hit a car' - how come the car is still between the warning posts and half way along the engine? They also say the '........... locomotive ploughed into the silver Mercedes', at 7mph, I beg to differ but the picture suggests the 'Merc' ploughed into the train! All this, a...

How about procuring three screws (max length 1mm < back to back dimension) with nuts, say 2BA/M5 and placing them between the backs of the flanges and carefully and evenly jacking them apart. Only one wheel will move, but you probably don't need to go very far. The only drawback is: if the left hand...

The tightness can be felt with the loco not in steam on my table, it seems to be at this position both in forward and reverse:

If the regulator is shut, and the loco is new, could it be just cylinder compression?

If you wish to store superglue for any length of time - keep it in a fridge.

A freezer is better, but it has to defrost first before you use it.

If it is fresh when you buy it, it will keep for years.

Compressed Air!
It works under water here.
Brandbright used to do a system, but there are others.

I'm sorry, but why worry if you can't get it out? On a 16mm boiler @ 50 psi its not going to block the steam outlet, its too big, and the are no other steam ancillaries. If it does, then at least you know where it is! If you have a piece of similar tube, put it in the oven at 150 deg C and see what ...

I suggest you are confused by scale and gauge. A drawing of a 2.5" gauge locomotive is meaningless unless you know the scale, or can make a guess of the author's intentions, is it intended as a narrow gauge or standard gauge engine? If you believe the drawing is of a standard gauge loco, then the th...

It all depends on your definition of a water tube boiler, would a 'smithies' type count? I have built a small yarrow boiler, though not for a 16mm engine, but for a boat and while it produces a lot of steam, as you'd expect, the most time consuming part was the casing and insulation. I had expected ...
