A matter of scale

In Episode 107, I had a look at the Amana Tool miniature inverted copy router bits from Toolstoday.com.

Although you get an idea of the size from the video, I thought I’d give you a closer look, and compare them in size to a Australian 5c, and the USA cent and quarter.

What I really wanted to show however, is the size of the bearing that is used on the smaller trim bit.  It makes for a smooth copying operation, and so the router bit doesn’t burn at the rub point.  Now when I say it is small, I mean small.  It is in that first photo – have a look at the 1c piece.  However, to make it clearer, here is a real closeup!
