    Default small collets

    Hi Everyone,

    I'm trying to keep to 100% handmade to have some hope of a USP and selling something!
    With that in mind i'm having trouble with making small collets, normally round.

    Does anyone have a method for making tapered round collets at the 2-4mm size?

    I'm presently trying to use a round collet plate, but it often results in the ring of metal going in wonky and coming out... wonky!


    Very much appreciate any suggestions
    Cheers
    Nick

    First of all welcome; are you working your way down with the collet plate that is progressing from large to small and taking it slowly, you cant just bang in in and hope it will
    come out ok you have to (for want of a better word) tease it into shape

    Hi China,

    Thanks for the welcome.

    The problem i have is that the collet plate is to big.
    Is there a collect plate with smaller holes than 5mm?

    Cheers
    Nick

    That's a nice piece of kit china!

    I think my smallest plate goes down to 3mm and was from ebay for less than £20. I'm pretty sure the dreaded Cousins have them as well.

    You might look at his page on how to use a collet plate: https://www.google.com/search?client...a+collet+plate.

    For me, it's a good idea to start with a piece of tubing, hard at first, that has had the ends filed square in a filing block. Then I start it gently on top of the block, to begin the funnel shape before inserting it into the appropriate hole.

    It's best to use a small hammer and light taps and anneal when you feel resistance. Dennis
