    DIY Positioner?

    I could stand a welding positioner but man are the expensive. The smallest ones I can find are still twice the size I need. I'm making small parts that I can certainly do by hand but a positoner would come in handy. So I was curious if anybody had ever built one?

    Hi quasi,
    Try searching WW forum, there are a lot of positioners.
    A little one posted before is http://weldingweb.com/showthread.php...ght=positioner
    Do you need something like this or smaller? What size of pieces will you weld?
    Best Regards
    Mauricio

    Re: DIY Positioner?

    Hi Quasi, I made a small one using the centre spindle housing from a top loader washing machine.

    This gave me an alluminium housing about 60mm diam and 300mm long with two ball races inside and a spindle with a 75mm diam flange on top.

    I added a small electric motor I got out of something that rotated, and a couple of small vee pulleys.

    The earth pickup was a piece of brass plate that contacted the spindle to form a sliding contact.

    The 2nd last thing was the shroud off of a 2 stroke lawn mower engine, to keep the welding sparks off the motor etc.

    Last thing was a foor pedal to inch the spindle round as I migged the job.

    It worked well and I used it to mig hundreds of small items I had a contract for.

    Photo if you need it, it's very agricultural, but it's a case of available parts cobbled together from the scrap box, one week end.....couple of hours work.

    I"ve been looking to make a inexpensive one but have no ideas.

    I did find this a long time ago but not sure harbor freight still makes them.

    Darwinian evolution used to fix stupid. Now that humans have mostly removed themselves from the process of natural selection the survival rate of idiots has skyrocketed.
