    For the benefit of math challenged and anyone else interested I have prepared a spreadsheet to calculate that .0627 dimension as well as 2 different ways to measure the mouth diameter. If anyone is interested I'll attach it in my next post. Eugene

    I mean no disrespect to any reader of this thread especially of the OP, but any of my apprentices could tell you the depth of that countersink. Most of them could derive it without picking up a pencil, just their calculator. The others would be able to sketch it out and then do the math. No...

    The OP's image clearly describes the countersink requirements according to drafting standards. I don't know what the fuss is all about. Eugne

    Lennard, of course you're encouraged to be innovative. You can still do that when working for a customer, just don't try it without consulting with whomever is authorized to implement what you are proposing.

    Yes, Peter that is my method but I was replying to a posting by Cogsby. There is also a likelihood that an error would occur if the thru hole is not to size. That also needs to be accounted for if working to tolerances. If you're working for a customer get his/her approval for any variances...

    Yes and no. For this to be true the c'sink would need to have a dead sharp point. If it had even a .005" radius the mouth diameter would be oversize by .0045. Trivial maybe but needs to be taken into consideration if working within tolerances. It's not a good idea to try to second guess the...

    The .0627 dimension was never on the drawing. It was provided by me in answer to the OP's request for a down and dirty method of fulfilling the requirements of the c'sink specs. I stand by my procedure. Drill the hole to size. Replace the drill with the c'sink. Lower the c'sink untill it just...

    If you copied BillC's sketch you should know that the use of (a = b x Tan B) is not correct in this instance. Eugene

    I believe you need to rethink your logic on the total travel. I could be wrong. Eugene

    Some users prefer to work in degrees rather than a constant X increment. You have your choice. It really makes no difference. Gene

    I have created a spreadsheet to do this. If you make your steps small enough there will be little work to get to the finished product. I'll attach it if anyone is interested. Gene
