Building A Small Simple Camera Dolly From Scratch and Rollerblade Wheels (if you have all the tools) 

Thank You!!, I have much more equipment to build and many more videos to make..

Depends on the type of metal, the saw i'm using is just a standard circular saw with a non ferrous metal cutting blade made by "diablo", depends what type of metal and how frequently you use it, here im cutting aluminum which is soft. for metal cutting I would use a corded saw, cordless have a very hard time with metal. be very careful using this type of saw to cut metal as you must have a very good grip on it and cut straight to avoid binding and kickback. they also have dedicated chop saws for metal cutting at almost any big box hardware store, Home Depot...Menards...etc.

Thank You. I just found an old Ryobi corded saw in the shed.. Gonna try it out and see how it cuts. Thanks again
