I got back to the shop yesterday and made some progress .
Trunnion pockets cut so back in the lathe for the final bore . I should explain that a 2 stage bore is necessary because of my indexing fixture , it is made to hold inside a GB bore .
Setting up with a 2.5" bit with extension . 13.5" to go .
1 hr and 45 mins later .
The new boring bar , I still have to cut very slowly to avoid chatter .
Almost done .
The lines in the bore look bad , but you can't feel them .
Looks like a good fit .
The HMR quick weight loss plan . From 148 lbs to 83 lbs in 20 hrs . Monday I will make and attach the trunnions .
