SPEEDY 5inch boiler stays

[Speedy Builder5Participant @speedybuilder5]

Can anyone help. Following LBSC's writings in the MAP book 1978 and sheet 5 'Mechanics' there are no dimensions for placing the 1/8" stays on the backhead / fire/door plate. Reading from the text, there are 47 stays each side of the firebox, 6 in the throat plate (All OK so far) and 3 in the wrapper. Now by my interpretation these would be in the backhead / door plate – BUT 3 do not look like enough. 1/8" stays are drawn at between 3/4 to 11/16" pitch. Thus there should be at least 10 to support the doorplate.

Can anyone shed a bit more light on the positioning of these stays? I intend to use 1/8" copper rivets and silver solder in place instead of using 5Ba/1/8 x 26 as specified in the drawings / text.

Does anyone own a Speedy who could have a look at their backhead/ fire door plate and count the number of stays please ?
