    Hello friends. new member here
    Its my dream to build my own tuning keys for guitars which i build myself.
    i came across with a workshop which has M1TR machine on which they do their milling job.
    the jobber says that he can make the base plate from brass. but needs some drawing which
    will be very helpful to him.
    can anyone help me in this regard to know the distance between the centre of the worm and gear?
    is there any member who is classical guitarist who know about the gear and worms
    the ratio generally is 1:15 and OD of the gear is about 10-12 mm.
    is there any ratio or anything like it? or any drawings will be more helpful
    there is VMC too in my vicinity . but it needs 3d model in igs or step files.

    waiting for ur help

    My mate across the road makes and restores violins. I have made some worm gears and pinions for him in the past. I shall ask if he has a guitar piece . I made a special tap/hob thingy to mill the worm wheel in the lathe .

    I would use the .7 module. The tooth form is slightly larger. I will look for that module on my emco super 11, I know my colchester triumph 2000 has it. I could make you a couple to start. Do you have any machining capabilities?

    it means i should go for OD-12 and 15 Teeths?
    i dont have machining capabilities.
    but i do have industrial area near my surrounding so that i can get made some modifications
    should i use phospor bronze or aluminium bronze for gears?
    if u make wat will be price per set?

    Phosphor bronze usually for gears. Send me dimensions and I will make a sample for you.

    I shouldn't say anything,as bad as my pictures can be. But,I have to plead that it was because I had this small Canon auto focus camera. You could not focus manually with it. It focused very often on something near that you WANTED to take a picture of,and your object was really out of focus.

    I now have a Canon Rebel,which I CAN focus by hand. So,hopefully my pictures should be better.
