    Default Can anyone here bead roll a wire edge on sheet metal?

    Hello
    Im working on restoring an old lathe and cabinet. There are some leaf hinges on the cabinet that require half the leaf to be replaced and this will involve getting some 0.040 sheet steel bead rolled around a wire edge with a wire of 0.125 diameter. Heres a pic to show the idea.



    Anyone know where I might be able to go to get someone to fabricate a piece like this say 8-10 inches in length and about 1 in width? I tried some local sheet metal shops but they dont have the dies necessary to do something this small. It's small enough that I could have a guy/shop mail the piece to me.

    Thanks!

    I think a swaging machine is required and surely they are not too difficult to make....?

    .... if you cant find someone who has one.

    They were once upon a time (pre WWII?) essential tools in panel shops and a favourite tool of old time tinsmiths for making pails etc.


    Have you considered piano hinge?

    Maybe not 100% original but easy enough to use. Available from many hardware stores.

    I can do it but you will have to supply the bead roller.

    Have a look at pages 199-200 of Guy Lautard's The Machinist's Third Bedside Reader.

    For small jobs like yours, this can be done the old-fashioned way, with a hammer and the following simple tools:

    There are die sets to do this work. This type of die is usually illustrated in press brake die catalogs. I used them a lot in years gone by (almost 20 years ago.) To do this by hand would ceretainly be a challange. Not the same as illustrated in the previous post.

    Usually done with a tipping wheel. See post #44 for a DIY version here.

    A Google image search will produce many more examples.

    Possibly make up a tool like a dull can opener to roll the edge?

    I made up a bead roller specific to my needs and it works great. With some different "dies" I am sure something like it could roll an edge around on itself.

    +1 for the piano hinge.

    But they need straight surfaces.

    Some are pre-drilled for counter-sunk screws but can be used with counter-sunk pop-rivets.

    Go the extra yard as regards cost and buy brass ones (not steel) and oil them regularly and you will have no rust or "binding" problems.

    Pivot pin should be brass as well.

    If the steel frame or door is distorted use common brass hinges - which are shorter - with similar profile to that of a piano hinge.
