Third Hand for Electronics, RC Aircraft, Jewelry etc.

A Third Hand is Extremely Useful for Many Hobbies. There Are Two Choices of Third Hand Bases: Four Arm and Six Arm Base. The Four Arm Requires Four 10 mm x 5 mm Neodymium Magnets to be Pressed into the Bottom, Which Can Easily Be Done on a Table. I Affix My Large Metal Washer as Weight to the Third Hand Using Magnets. Note that the Four Threaded Holes Have Another Smaller Hole Perpendicular to the Threaded Hole for Running a Wire Inside the Flexible Arm. You Could Then Use the Arms as a Probe When Troubleshooting Circuits, Making Them Extremely Useful in Debugging Electronic Devices. The Six Arm Base Does Not Use Magnets. Instead, You Can Install 5 mm Bolts and Nuts to Affix It to a Wood Platform or Use it Without a Platform. The Arms Used Are Flexible Coolant Hoses That Can Be Bought Directly on Amazon, Along with the Alligator Clips. I Found Using a 6/32 Bolt to be the Best Solution for Getting the Clips into the Flexible Hose, Which Allows for a Good Fit and Also Enables Rotation of the Clip. To Get the Head of the 6/32 Bolt Off, I Use an Angle Grinder or Hacksaw, Making It Easy to Install and Remove the Alligator Clips as Needed.
