Sticky mat to hold objects

I came across this mat in a CNC forum. The manufacture claims it can be used with a laser. Anyone use something like this before? The 12 inch x 12 inch is about $60.00 USD

Interesting electrical issues

Interesting electrical issues

So today I was working on the slate garden markers for my friend. After 4 hours running, and before a marker was finished, the GFI breaker blew. Swapped outlets on a different circut and it blew too after a few minutes. Ran an extension cord to a non GFI breaker and no issues. The most interesting part is the power supply squealing almost went away. Things that make you go mmmm!
