Hi
I need to replace the cylinder head studs on my Ruston APR 2 1/2hp as the old ones have been stretched.
They are 1/2" Whitworth which I can easily make on my lathe but I don't know what grade material I should use or if I should harden them.
Can anyone advise me on this.
Regards
Liam
Liam,
Cant go wrong with EN8 steel I would say, but dont harden them ! I dare say EN3B would be fine also (Mild Steel) - This is the grade we used for my boiler studs...
Just my thoughts...
