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 .
