I found this on another website and thought I would share it here. It seems to be the safest way to cut a factory looking handle in boxes that we build ourselves using a tool made for tire work.
Heres the website for the tool. http://www.olivercorp.com/rubberhog_products_details.cfm?category_ID=16
And heres the link to the website explaining how they did it.http://www.beesource.com/forums/showthread.php?t=245973&page=5
The poster's screen name is Carlinmo and he has a link to a picture of the handle that it cuts out. The tool however isnt cheap at all-I know cuz I just ordered one but they are supposed to last a lifetime and I think they would be way safer than the plunge technique on a table saw that Im using now as well as the moulding head cutter that Ive looked into. This tool is used on a drill press and produces a darn nice looking handle.
Yes, it is expensive and yes I know the arguments of nailing strips on the sides for handles, but I just like the look it produces with less risk of losing a finger or two in the process.
