No, I never did, but im not doubting a cylinder can be honed 10 over, however thats not what you are saying
You want to bore a cylinder with a home made boring bar fabricated out of a drill press
You were given many reasons why it wont work because if it did somebody would have done it already
Ive written you about a greatly talented machinist I knew who made a set up to bore a shaft bearing in the ship, ive told you about my experiences in the trucking industry and power house but in these instances machinery was designed for a specific purpose.
If you're an experienced machinist or engineer there is no doubt you could fabricate a boring bar but a boring head on a drill press? No I doubt that alone will accomplish your goals for the reason you were told
Im not looking for an argument here and I previously even objected to you being called names.
I would be interested to know how you plan to hold clearances and how you will address things like chatter of the cutting bit, what about defection in the drill press shaft
Best of luck
