Welding K1100 Cylinder Head

[minimutly]

Well that's two hours of my life I won't get back - still needs a last cut, but it has a slight bend I want to get out first. View attachment 494148

I find this machined down cam a bit heavy for a simple oil pump driveshaft, so fancy taking a drill to it. Are there any gun drilling experts on here? Can I do it in stages with a drill tigged to a slightly smaller rod? Will the drill stay straight?

Make a new oil pump shaft out of alloy or Titanium.
Can't see the point really as it's hardly got any rotational mass that the engine would see.
So no benefit........

You're right, but the race engine is just that, and you've probably gathered I'm a pedantic so and so, and something this simple being so heavy offends the inner me...

Well if you cant be arsed make a lighter one, you could cross drilling it which would be easier......
