Downsize your pocket cargo with a custom-fit keychain. Editor Sean Captain ditches the ring and uses more tool than necessary to trim a small bolt to just the right size for his set of keys. (For a slightly different take on the project, see the site that inspired us: carlitoscontraptions.blogspot.com).
This is why they invented the key ring...and the key chain...
Who holds a grinder like that.
What's with the countless craftsman plugs for one 5 minute video. It wouldn't have been so bad but the "where's my flat head screwdriver" routine put it over the edge. Pretty lame and cheesy.
If the editor had of done some research he would have known that it is better to add thin washers between the keys. In my case, I used small plastic washers.
This "it is better to add thin washers between the keys. In my case, I used small plastic washers" is a great tip.
Locking Nut? What if you need to add another key or remove one?
lock nuts are removable. a better way would be to have a "flat nut" with a drop of lock tight. with the threads protruding inward, the outsides would be flat.
terrible video though, blatant advertisement, hoped pipsci was better than that
I did something similar to this, but a bit more extreme. Use a chicago style nut and bolt (looks like 2 screws,but one fits inside the other)to get a lower profile, and grind the heads of the keys down so that they are the same width as the shaft (think of a multi blade pocket knife with keys instead of blades). You can use the other keys as a handle to get leverage when you turn the key.
a little too much Craftsman bling, but good how-to, nonetheless.
