should have read the specs before ordering! now i need two new drill bits.
- Axis: 6.35 mm
- Bore: 8.5 mm
they also don't specify anywhere what the spacing is between them, so i'll have to assume it's standard 119mm or 120mm or so between first and last centre, and try that on a piece of scrap wood to confirm.Harley Benton Parts 6in-L Vint Machine Heads
6 In-line vintage machine heads Kluson-style machine heads, For all Vintage Fender 6 In-Line 50's and 60's models, Oval knobs, Axis: 6.35 mm, Bore: 8.5 mm, Colour: Nickel, Includes bushings and fixing screwswww.thomann.de
The axis is the shaft diameter I’m presuming- so you don’t need a bit for that
Try a 9mm bit and see will the bushing hold, just to make your life easier.
The centres for the holes should be standard,
