Re: Adding a topping lift, or the heck with sheaves
Stainless is so much fun! Stainless is very hard so drilling generates a lot of heat and work tempers the steel. You need to buy a set of colbalt drill bits. Carbide will do in a pinch but will get dull. "normal" bits just get dull and won't cut SS. Use cutting oil to keep the work "cool" and well lubricated. Drill very, very slowly and use a lot of pressure on the drill. When done properly, the drillings should come out in "twists" If it is coming out in "chips", you are probably drilling too fast.
