Re: Thread converting

Only with the appropriate adaptor. BSP and NPT may have the same tpi at 1/2" dia, but the angles of the thread form are different (55 and 60 degs. respectively). Close, but not close enough for pressure.

Re: Boiler questions

Is the prop tall enough?

Re: Ash pan

I would suggest it depends entirely on the size, shape and configuration, but if designed well, 16G (1.6mm) should be more than adequate.

Re: flexible shaft coupler

The problem with Hooke's type universal joints (as shown above) is that they do not give true constant rotation, unless in an absolute straight line, in which case there is very little need for one. Ideally they need to be used in 'aligned pairs' to cancel out the increases and decreases of rotation...

Real exposure to the machines, and real understanding of them, carries more weight than having just the cre...

Definitely silver soldered, or TiGed, if it's to take boiler pressure.

Re: Exhaust

Mike, just so I get this straight, what you are saying is that your float-valve is really a self-regulating by-pass valve. There must also be some minimal evaporation losses from the hot-well, so you do still need to keep weather eye on the gauge-glass.
