Re: seized, broken bolt Boston

I am often forced to do hand work on stuff that cant be carried to a machine

The value is such I would carry it to a machine (I have the machines ) if you can

On and Atomic 4 block for example the 18 head studs fail here and there and after cleaning up and using the still good studs and the head as a drill guide works well

You just need to buy a letter size drill that exactly fits the clearance in the cylinder head and use this drill to spot the hole so it is exactly centered

You can then drill through with the right size drill and the head will serve as a guide in keeping a hand drill true and a good taping guide

On really crazy stuff I can drill up a guide on the Bridgeport in a few minutes

If a dirty bottom slows you down what do you think it does to your boat
