    Probe Halo

    I can't make one for $40.00, much less go buy a $2K printer to make one. LOL Given that, I purchased one. Thanks for the heads up!

    Ball ended Hex (How to machine?)

    What about a custom ground profile (form) mill? Mill the Hex OD with a standard cutter, then clean the ball end with a form cutter.

    Rigid Tapping small hole inconsistencies

    Cutting Taps for 6-32 are the weakest taps know to man, IMHO. I toss in a 1/8" parabolic, drill 5/8 deep in 1 shot, and roll form 3/8" deep, using emuge, plug, forming taps. Our coolant is Trim E206 at 10%.

    Rigid Tapping small hole inconsistencies

    800 RPM for a M3 tap is really slow. I would run a roll tap, and shoot for 70SFM (2266rpm) if your machine will allow. Peck tapping is ~probably~ what is messing with your holes, or slop in the machine/holder etc. Would a roll formed, 70% thread work? If so, shoot for a #36 or Ø2.75mm tap drill...

    Sliding markup percentage for small to large cost for subbing out work

    Ox, I doubt it will happen. This company is used to big parts coming from big shops. I think my markup will take us out of consideration. Having said that, if they want us to supply the parts, they have to expect a markup. ([shrug] we will see.)

    Sliding markup percentage for small to large cost for subbing out work

    Well, I hope this on works out. The 'shop' in question is owned by a member of the Godwin family, part of Knust-Godwin LLC. As I could be on the hook for my own money, I went 17% with the following terms: 20% at PO, 30% due upon receipt, 2%Net30. (<-- typically 2%Net10/Net30) If they opt for...

    Sliding markup percentage for small to large cost for subbing out work

    All said and done, the quote was not 560K, but only 448K. I would love too, but it would be a large Horizontal, Bullard VTL, and a lot of tooling & fixturing. Not economical for this application.

    Anybody have all the 9000 series macros for a renishaw OTS,probe, etc, on a 2007 VF-4, to share?

    Something has happened to our macros. We cannot get the Table Probe (tool lengths) to operate, and the consensus is corrupt or missing macros.We were considering dowloading & saving all the current 9000 programs to a USB, delete the 9000 programs on the machine, then re-load them from provided...
