About This File
This is a jig I made to drill a pilot hole in a 10cm gazing globe. The globes I used were Rome brand purchased thru Amazon. Each had a single hole already drilled. This jig allowed me to drill a matching hole directly opposite.
The base has leaves which can be clamped to the drill press table. It also has a peg which fits the existing hole in the globe. I clamped down the base, fitted the globe to the pin in the base, pushed the cylinder down over it and then the lid. The lid has a center hole.
There's also test cylinder file which is only 5mm tall. If you want to use this jig I suggest you first print the test cylinder and make sure it is the right size for your globe. It should fit very snugly.
