How to Make a Hole in the Middle of a Golf Ball

If you’ve ever tried to make a hole in the middle of a golf ball, you know this can be a difficult task.  With the right fixture, however, it can be pretty straightforward.

Safety Note: Be very careful when drilling golf balls.  Be sure to at least wear eye protection as with any shop operation.  Liquid core balls are especially tricky, as they are under pressure and have been known to spray hazardous liquid when pierced, so avoid this type.

Why would you want to put a hole in the middle of a perfectly good golf ball, you might ask?  My reason was to make a “ladder toss” set for my own amusement, but maybe you would like to attach a golf ball to the top of furniture or make a golf ball ornament.  Possibly you’d really like to screw your friend’s (enemy’s??) drive up by hollowing out the inside of a ball…  The possibilities are endless!

So how do you put a hole through a golf ball?  Probably most of you, upon reading this, thought about using Read more »

Draftsight… Limited 3D capability?

I have used Draftsight at work for several months now alongside my installation of Pro E.  Although I don’t do any “creation” of parts with this package, I generally used to open .dwg files from vendors or colleagues.  It’s done a very good job with the 2D files that I’ve been opening, but today I got send a 3D .dwg file that I assume was made with AutoCAD.  To my surprise, Draftsight opened it up with no problem!

Here are some views that it generated, illustrating that you can pan rotate the image as you please:

Capacitor Safety for Cameras

Capacitors are fairly common components when it comes to modifying/breaking electrical components.  However, they can be quite dangerous.  According to “repairfaq.org“,

“While accidental contact with capacitors on a 3.3 V logic board isn’t going to result in a shocking experience, this is not true of many common types of equipment including TVs, computer and other monitors, microwave ovens; the switchmode power supplies in some VCRs, laptop computers, camcorder battery chargers; electronic flash and other xenon strobes; laser power supplies, and many other consumer and industrial devices.”

Disassembled ==> Could be bad...

Most people familiar with electronics should know to be careful around TVs, but what many people wouldn’t think about is the smaller things, especially electronic flash devices.  Quite a bit of power is required to use a flash, and as such, quite a bit is stored in a camera’s capacitor.

I did an article about triggering your camera with an air freshener, which should be Read more »
