A solution if anyone has one.

I made the bushes for my Minnie to the sizes shown, i.e with a 7/32 x 40 Tap holes.

I do not fance making this. I can purchase from Macc Models what appears to be a suitable alternative, but the smallest I can get has 1/4 x 40 thread.

I think I have enough metat remaining to re-drill and tap.

Is this the best altetnative or are there any other suggestions ?

As always any help and advice will be MUCH apreciated.

Best wishes to all

Probably not long enough to clear the third shaft, you may be able to make up some sort of extensions to overcome this.

Hi Malcolm,

Why not make your own water gauge? I am quite sure you will be able to make something far more satisfying than a standard commercial fitting, plus with your 7/32" x 40 TPI ME thread.

They are not difficult to make.

I have always made my own boiler fittings, and have never bought commercial products.

Hello Malcolm,

I'm with Julian on the subject of boiler fittings, they are very satisfying components to make, further most commercial boiler fittings seem to be made from brass, and generally where fitted below the water line will slowly dissolve before your very eyes! The water gauge for Minnie as pointed out is specifically designed for that engine, so I'd doubt if a suitable item is made commercially.

As always thank you you.

Jason B. I am going to try the 1/4" item. But very grateful for your comment on the 3rd Shaft
