    Default Replacement Tuning machines for Eastman MD515

    I love my MD515 but the tuning machines are stiff and temperamental.
    Iím not sure what the ratio is on them but I would like to find a drop in replacement set that would provide a more granular ratio and be lest difficult to turn.
    Could I maybe get a few recommendations for a drop n replacement?
    Blessings,

    You might want to have yours checked out by a pro, or see if they loosen up by lubricating. The Eastman 500 series have the old style Schaller tuners and they are generally good.
    Anyhow, the post spacing is standard with those tuners and most new worm-under tuners will fit.
    Grover 309 are good, but might not be huge improvement over the Schallers. They do have a better gear ratio.

    The new hotness are the new Schaller Grand-Tune but they are $200+

    I personally like Rubner tuners, but their selection for F style worm-under looks pretty low right now.

    Thanks Al...
    Looking over the options I really like the only in stock Rubnerís but aside from them being a bit out of the reasonable price range for my 515 they are only 15:1 ratio..

    So I think I will end up with the Grover 309ís more than likely. Looking at this I would really like to swap out the tail piece for a gold one while Iím at it and go with the golden tuning machines.

    Iíve just always like that on a dark finish.

    I guess before I pull the trigger I need to see if I can find a suitable tail piece as well, or just settle with the Nickle.

    Before you order those Grover's get the length of the tuner button shaft from the specs at the bottom of the Stewmac page and measure to make sure the buttons are going to clear your headstock. The Grover tuners are shorter than the Schaller's that Eastman was using. You may have trouble turning a button if they are too close.

    You might check out the new Schaller Grandtuners ! They look great and half the price of Waverly's !

    Can't find any spec's on the Schaller Grandtuners... might be a good move with the 18:1 ratio but I'd like a bit more info before making a jump.

    I personally wouldn't spend $200+ on new tuners on a mandolin that is worth $600-$700. It may sound great and be wonderful to play, but I'd see if I could get the existing tuners to work better and put the $200 in the new mandolin fund.

    Well that is being done right now. I've got it in for a tune up and attention to the tuning machines is on the list. But I still would rather have a more granular ratio on the machines regardless. So I will likely end up changing them out sooner or later.

    The Grover 309 will be different, but not hugely so. The Schallers should have a 16:1. The Grovers 18:1. As a reference, Waverlys have a 16:1. Rubners are 15:1, I find the Rubners superior to the Grovers and Schallers because the machining is better and the gearing has less play, even though the ratio is lower. I think that is why Waverlys are also well regarded. Not the gear ratio but because better machining and assembly makes them work more accurately. Ditto the new Schaller GrandTune

    I looked over the Rubners and thought they seemed outstanding from a design standpoint. I might go that way. I'm not sure what the stock ratio is on mine but if it is smooth and capable of zoning in tightly on the pitch I'm working on, that is all that really matters. I only was thinking of the 18's for granularity.

    So, I may have to do that.

    I asked Rubner about their inventory and they said that many of the models will be restocked next week.

    If your mandolin has the older style Schallers it will be 16:1. My guess is that they are slipping or binding, causing them to move in steps instead of smoothly. It could also be that your strings are binding in the nut or bridge slots, unrelated to the working of the tuners.

    Older as compared to the new GrandTune series which just came out in the last 6 months.
    I suspect this is the tuner you have:

    The other side of this coin is that if the tuner problem exists because the holes weren't drilled quite right changing them won't change anything.

    Right.
    If this is the problem and you are the original owner, you should have a lifetime warranty that would cover the repair or replacement

    I put some Rubners on my Mid-Missouri M4 and absolutely love them. The original tuners were fine, but a little stiff. The Rubners are just so smooooth.
