Articulating Arm for Woodturning Hollow Forms

[@j.s_cabin]

I have a somewhat similar solution partially ready. However, I only used ⅞" bar as the structure and the joints are 2" welding sleeves with ⅝" holes and bolts. No bearings. I don't have the turning arms ready yet, but I'm already looking forward to trying the arm

Thanks for your comments. I would recommend you consider the thrust bearings for every place where two pieces contact each other They look and act like washers but with tiny bearings. They will make the tool move more smoothly. They are less than $5 each, come in all sizes and are at most bearing supply stores. As I stated ,my Arm is very heavy and lighter steel would have been better. Email me a pic when your done [e-mail]
