If anyone says the internet is just for porn (I'm a student!
) then they're lying! Was having major problems working out the position of RS15 on plates CP3/4 so used the old search function.
Success! Found a 2 page long discussion between HandyAndy and NickHardy on just this problem!!
Without this forum I would probably have made a terrible c*ck up.
Did find find one error, drilled two of the holes on one of the plates on a random line about 10mm too close to the other pair
Fortunately there was room to drill them in their proper place, now just have to weld up the mistakes and clean it up
