The idea behind using a smaller cutter on thin material is based on the amount of surface contact you have (diameter contact vs vertical contact). A smaller cutter will cause the material to chatter less than a large cutter. Chattering material will chip your cutter. Yes, you could profile it and drop it out as well. Full width milling can leave a rough finish, just plan for a clean-up pass around it. As good as that full radius looks, you don't really need it. Just use a 1/4" bit and leave the back square. When you don't have coolant flood (like in a CNC machine) you want to slow down spindle speed significantly because stainless generates quite a bit of heat and you don't have enough cooling mass to remove that heat. If you must use stainless, 400 series would be a better choice when milling, as it lacks nickel. I've milled my fair share of tool steel - A2, D2 and 4140PH being the main ones - and I'd rather mill tool steel than 300 series stainless.

Not certain.

Maybe. Maybe not. Won't matter to him. He's used to controversy.

My friends Dave and Cathy keep their landscape equipment in my yard and in appreciation often surprise me with thoughtful gifts.

They found this cool pump oiler at a garage sale on the weekend..

I prefer the patina look but this one had too many sharp edges.

So I spiffed it up.

I like the unspiffy look better but I suppose if one was cutting up their hands with it, then it had to go.

Same here. Especially when I look at before and after.
