I have found a replacement water gauge for the Aristo Mikado. The original is a bit oversized 7mm X 1 threaded gauge.

Reeves in the UK makes an 8mm threaded gauge but they advised against drilling and tapping to that size with the original bushing.

The replacement I found from Coles Power Models is available in 1/4" and 5/16" sizes. At .312 I am hopeful there is sufficient material around the fitting to make it safe to D&T to that size.

Are there any specs or recommendations as to the amount of bushing material surrounding the fitting?
