extra coarse sandpaper

If you learned all that from Norton, why are you asking the question here . . . . again? Save it for your usu. entries on Trolls are Us.

Then you will be able to position the disks to improve the odds. Obviously,

Stop drinking!

Whew !! For a moment there I was worried you might rub me out with one of those 5" discs that may or may not have a single abrasive particle on it.

Bob, I am prescribing two 750 vicodins for you. Take them. wait an hour, read post again. I feel there is hope for you.

P.S. If you were a woman I would know the problem.

Vicodins, huh?. I think those are for pain. Your OP wasn't painful -- just unclear.

I was just trying to be charitable.

They're used mostly for finishing at Harbor Freight.

Couldn't you just bash the part with a rock? Amounts to the same thing.

I had a tech once, very good hand, except everything we had to disassemble regularly bore a genuine hammertone finish, and I don't mean paint.

finally, finally I get the joke. :-)

yes I've seen harbour fright and it was quite agricultural in the precision area and got increasingly refundable in other parts of the shop. :-)

I thought myself that some of the rough finishes were just a poorly selected alloy that they'd tried to machine but now I'm not sure. I use a chinese drill vice on the shaper. it is dreadful but an accidental plane or two from a low cutter causes me not a moment of anguish. I modified the abysmally threaded clamping screw yesterday and found that it was the most beautiful free machining steel. How the wogginese managed to get such a poor finish on a beautiful piece of free machining steel has me beat. you'd have to really be working hard to get anything but a beautiful finish, my tool wasnt even sharp and I managed a neater finish.

maybe your abrasive paper is actually sold in china as a precision lathe cutting tool. :-)
