Replacing tuning machines

  1. There seems to have been a mini-spate of tuning machine questions lately, so I'll throw mine in:

    I was thinking of replacing the machines on my old Engelhardt.

    Are the two-on-a-plate machines pretty much universal, or am I better off getting the four individual machines? Is this a "get-thee-to-a-luthier" job?

    I just replaced the "plate" machines on my working bass with good-but-not-luxury quality "single" machines from I'm real happy -- they're great gears and Gary always does square on the price.

    If you go from plates to singles, there is the bonus of allowing more of your bee-yu-tiful headstock to show. The downside is that plates sometimes cover a multitude of luthiery sins. The only special tool I needed was a big honkin' reamer to slightly enlarge the holes.

    Lemur sells the stock two to a plate machines. It's something you can do yourself. (Provided you lay the instrument down, mark the bridge location, maybe lay a weight on the top, and use a hand screwdriver to remove/install the little screws that hold the plate down.) Depending on the size of the holes, you also may want to use a >>slightly<< larger screw for the new machines. Home Depot/Lowe's type places have a good selection of silver/gold screws.

    Is there a standard hole pattern for the two-on-a-plate machines? I mean, can you mount any type of these in the same holes?
