c 1" Tooling Ball needed or Advice Please
Ladies and Gentlemen,
I hope you are all staying safe in these uncertain times. I'm about to drill the oblique port holes in my 6" Scale twin cylinder casting. Joe Pieczynski (USA) has just posted an excellent (to a newbie like me) Youtube Video on this and uses a Tooling Ball. I can't find any for sale in Europe - all available have to be ordered from the USA with substantial Postage etc. Does anyone have one for Sale / Hire please? Or does GB Engineering use a different tool and if so what is it please. As ever your guidance / advice will be very gratefully received. Kind regards. Andrew |

Does it have to be a 1" ball? I have a 1/2" one that you would be welcome to borrow. It has a 1/4" stem (if I remember correctly).I can measure it properly if it is of any use.

Thank you.
Here is the link : https://www.youtube.com/watch?v=KjQscFVgQgU&t=185s A 1/2" would probably do - I went for a larger simply because I'm building in 6" Half-size scale and hence the cylinders are 3" diameter. Having said that I feel 1/2" should work just as well!! I'll pm you. Kind regards, Andrew Last edited by clayton21; 10th October 2020 at 07:29 PM.. Reason: Forgot to paste link in |

I’m completely lost as to why the design calls for an orphaned stud in the middle of 2 ports.
Why not rotate the stud pattern by 30 degrees and drill a single port? On a full size, surely that must significantly weaken a casting? |
