IMO Beryllium Copper, being about 2% Beryllium is not bannedBrian.G wrote: @ Tok, Beryllium copper, wasn't banned then,
in grades for both electrical and mechanical applications, it's a well-established material (the electrical grade is almost indispensable)
Beryllium/aluminium alloys as used for pistons eg around 50% Be are banned
such materials (eg 'Lockalloy') have never established themselves in aerospace

the tapered cam surprised me (didn't the F1 BMW and others ?? use finger followers and untapered cams ?)
do we have a dimension for the cylinder bore ?
