Some time ago I was fortunate to find (given my location in Nova Scotia) a Royal Chester model, complete (well almost) but in pieces. The boiler had never been fired and was made by the well-known and regarded Mr. Chambers. A full set of drawings and the Hughes book were included.

I don't think the engine was ever assembled, as some 'fettling' was needed a few parts to get holes to line up, but generally the workmanship is to high standard and it has been a pleasure to undertake the build. Reference to the drawings and book, along with looking at photos of the model on the internet have all helped and provided some confidence along the way.

It is now time to make the small bracket used to support the crankshaft end of the trunk guide. Making the bracket is not a concern, but do really have to drill and tap my beautiful boiler to anchor the bracket? any words of help or encouragement much appreciated!

Many thanks

Thanks for the prompt replies!

This was my mistake. The set of drawings I have are short Sheet 9, which is for the boiler. Presumably it went to Mr Chambers. When I looked at the same sheet in the book, it showed details of the internal pad , as per JasonB's reply. I measured the pad location, as per the drawing, and while not a scientific test there is, from the response to tapping the boiler, a pad.

I'll make the bracket, but still approach the drilling and tapping with some caution.
