    hello,
    Long time lurker looking for information on installing a gotoh 510t fe1 tremolo in a MIM strat.
    I cannot find information anywhere regarding what size hole needs to be drilled to accept the 10mm fluted bushings for the pivot posts.

    I would like to know EXACTLY what size hole/drill to use.

    I have prior experience in machining and understand press fits but wood is completely different than steel or aluminum.

    Any help would be greatly appreciated as I am ready to start the installation.

    Thanks in advance.

    Stud inserts have splines on them. I've always measured the OD and used one drill size less and try it in scrap wood. The wood type has a lot to do with it. Some compress more than others.


    The dimension is on the stud here, but hard to read on my monitor. It looks like 610 and that most likely is wrong.

    Thanks for your advice.
    When you suggest one size smaller drill, do you mean 1/32 smaller or 1/64 smaller or metric equivalent?

    I would measure the bushing OD at a place without the splines. And drill the holes that size.

    While wood will compress I don't think you want the hole smaller then the OD of the solid part of the bushing.

    Just my $.02

    One of the comments on the Stew Mac link from above...

    Great but beware

    This is a great bridge. No complaints, but I wanted to heed a warning about the drill size for the bushing. The bushing itself is 10mm. If you use a 10mm bit your hole will be to large and the bushing will not fit tightly in the hole and could pull out. I ended up using a 25/64" drill bit, which is 9.92mm. This worked much better. Whatever you end up doing, test with a scrap piece of wood first. The difference between the 25/64 and 10mm seems very small, but I found it to be a much better fit. I suppose if you drill the 10mm before painting and done mask off the holes, enough paint would probably get into the hole and make up the difference, but mine came from USACG pre-painted and the holes were to small. They drill them at .38 and had I forced those in, I would have most likely cracked the wood. Otherwise, great tremolo.

    Marty, it looks like a diameter mark, then 10mm to me.

    Personally I'd still measure it first.

    Thanks for the replies.
    There really is not a smaller minor diameter so to speak on these bushings.
    The spline profile is V-shaped much like a thread and the theoretical point of the bottom of the V would be the minor diameter.
    The closest I can measure using calipers is @9.8mm assuming the splines are of even number 180 degrees opposing each other.

    Looks like I will try a 25/64 or possibly a letter W drill.

    Thanks!

    Try it in scrap. If you have to pound the daylights out of it, you need it a hair bigger hole.

    3/8th inch works perfectly..... I lightly "lube" the inside of the holes with a good past wax.. then use the drill press to press them in.... easier 'n tickin' off a Cop...

    Sounds like you're a precision guy so this may not apply to you, but beware any runout in your drill press spindle as well. Even the tiniest amount enlarges the hole. But you know that.
    BL is trust no measurements on a piece of paper and test on scrap, of the same type of wood with the same grain orientation.

    Good luck,
    Rex

    Thanks for the help.
    I installed the studs I think they will be fine.
    I ended up using a letter W drill .98mm

    I used a collet on a Bridgeport to minimize runnout and I think it came out perfect.
    It took light taps with a socket head cap screw threaded into the insert to seat it.
    The only slight error may be I set the studs about 1-1.5mm below the surface. I could pull them and put something in the bottom of the hole to bring the inserts flush with the surface but I want to avoid having the studs proud of the surface.
    Also,
    I could not find ANY installation dimensions in relation to how far from the neck pocket to put the studs to I found the center of the 6 screws and moved it .25mm closer toward the neck pocket because it looked better to my eye and I figured it would allow a little more room for the back of the tremolo block.
    I pre drilled the existing screw holes to accept a wood dowel as well.

    Looks great! How does it sound??

    Did it intonate properly??

    Thank you.
    It intonates Great and plays so nice particularly compared to the 6 point original bridge.

    My first impression of how it sounds is it rings or sustains more and it is warmer. The humbucker(burstbucker), lost some of its bite.
    I did not think the change would be so obvious.
    I think I will need to switch to a 500k volume pot for the bridge humbucker. While I’m at it, I may as well swap the MIM pickups for something different.

    Just clarify.
    The letter W drill is 9.8mm,
    Not .98 which I typed in my previous post.

    I also ended up needing a letter drill to get a perfect fit installing a Wilkinson WVS50 II K. An "S" was perfect. This was going into very hard wood (red gum, I think)
