That sounds like it could work AND it involves buying a new toy with the word "LASER" in the title!
Seriously though, won't the block equalize in temperature quite quickly, being metal and all? Should I run the test after a set number of minutes ie during warm up?
Any suggestions on where to buy one of these phazers?
