    I was going to try and offer some solace for Sturdee, but I don't think he cares anyway
    I have also seen the clamps, typical of all of his creations, functionality first, aesthetics are not an issue.

    Hi there,

    I know this is an old thread, but I've gone through and can't find a question or answer that I have on this clamp of yours.

    You have one piece of the clamp moving, and the other piece "fixed".

    Is there a reason why you wouldn't make the "dangerous" screw end the same as the "safe" end? Wouldn't it still work ok?

    I've "butchered" your photo to hopefully show what I am getting at, just in case my query is unclear.

    Thank you.

    There is a simple reason for the way I made mine and that is I used standard threaded rod. If you want to do it your way you will need to use a Right Hand and a Left Hand threaded rod for each clamp.

    Sorry, but there must be something here that I am missing. The thread direction only determines which way you turn the handle, doesn't it?

    As I see it, you only need the dual thread if you are trying to make both pieces of the clamp come together at the same time, (in which case you need 2 shafts with half of each thread, operating somewhat like a turnbuckle), rather than moving just the one piece as in your, and "my" version.

    In "my" photo, the closest handle freewheels in the left hand piece of the clamp, and the furtherest handle freewheels in the right hand piece of the clamp.

    In your version, both handles freewheel in the left hand part of the clamp.

    I there a reason that both handles must freewheel in the same piece of the clamp?

    Thank you.

    Maybe you're right and it could be done as you suggest but I know my way works.

    As it is now 8 years since I made them and I don't need them any more as my interest has changed I've been giving them away for a while now as gifts or presents.

    So I'm willing to pass on the challenge for you make one your way and post the results.

    Peter,

    I cant seem to find any pics on this thread and your links dont seem to work (could be my conection as I'm away from home this weekend). There was talk about a lot of pictures disappearing from the forum some months ago perhaps this happened here.

    Is there any chance youbwould revisit this thread and post some pics again?

    Regards

    Dave,

    The pictures disappeared from the forum a couple of years ago, when most pictures disappeared because of a forum upgrade problem. As I made these about 12 years ago I don't have copies either anymore.

    I made two types, one with two handles and one with only one but both using the same method. Three years ago I got a great offer to sell the ones with both handles and as I moves more into turning I sold them and bought another small lathe from the proceeds.

    I still have a few of the single handled ones and I would be happy to give one to you next time you're in Melbourne so you can reverse engineer the clamp.

    Peter.

    Found a couple of pics on my PC.

    The first is my modification to the clamp and the second is the original as per this thread.
