Work continues on the new/spare engine. I finally found the courage to try that welding trick to remove a bearing race from a blind hole. Bugger me, it works.
I shouldn’t have been so surprised. I’ve warped enough steel with weld to know that weld shrinks as it cools. Welding so close to a large, complicated, precision aluminium casting is a bit fraught though.
A small obsession 
Awesome Trick , My hand would have been shaking to much to weld that š®
