Re: What Makes a Machinist's Vise a Machinist's Vise?

When I retired, I 'needed' another vice in the garage/shop so I purchased this YOST vise from Sears. I have seen others similar and I am sure made in the same Chinese factory. I bought it from Sears in the hopes that if it broke they would honor their warranty. It is a good sturdy vise and other tha...

Re: Surface Grinding

Cary: This was bought so long ago that I don't remember what fraction of a carat it is. Maybe I'll just use it until it no longer works. Only time will tell. But thanks for the information.

Re: Surface Grinding

I did not know diamonds had inclusions, but maybe industrial diamonds do. In any case it appears it is getting to be time to retire this one.

Re: Surface Grinding

Here is the pic of the end of my single diamond dresser. I'm glad this subject has been brought up as I'd never have looked else. It would appear that it is near the end of its life. diamond1.jpg I think the diamond remnant is inside the red box as that is the place that glints when the light is rig...

Re: Surface Grinding

I have used a single diamond dresser since 1985 or so. It peels off a minute amount of abrasive in a very shallow pass done fairly rapidly. The 5sg wheel was recommended to me by a Norton Sales guy because I said I was going to be grinding hardened M2 tool steel. He said that this was the best wheel...

Re: Surface Grinding

First off, let me reiterate that I know less about surface grinding than anyone. I have had this old Delta T&C grinder since 1985 when I bought it to sharpen threading dies. Think Rigid or Oster pipe threaders. Since I didn't have a job or 3phase power in the garage, I bought and installed a 240V si...

Re: Is MSC Totally Useless?

Enco, MSC, McMaster-Carr or Joe's Bait & Sushi Emporium: can someone explain why screw machine length drills are so much more expensive than jobber length?

Re: Self-ejecting chuck keys Y/N

There are two classes of machinists - those who've forgotten to remove the chuck key and had it thrown at them and those who've been hit by one. My experience is of the #2 kind, both in surprise and embarrassment. :oops: I have not left the key in the chuck and turned on the machine after the first...

Re: Milling a helix

Very innovative, Harold. I see that you made the gear pivots adjustable in case you have to do this again sometime for a different pitch, etc.
Nice job.

Weekend experience

Friends and I spent hours last weekend and this weekend helping a friend itemize and get stuff ready for a garage sale of his accumulated 'inventory'. He is moving out of state to live with his son and family. I have been over-stressed ever since. Selling personal items is tough even when it is some...

Re: Soft Jaws

Your solution is best for your application, as was mine. The point being, soft jaws work for all kinds of situations. It might be fun to try some hexagonal stock.
Yours look far better and much more professional. Nice job.
