When one says "ball bearing" i assume it to be hardened as bearings need to be hard.  I was hoping for the clarification that we really need a hardened bearing, not just a steel ball.  Thank you and I hope that the distinct yes will be helpful knowledge for others in the future.

Size notwithstanding, I still have not seen confirmation  that one should use a hardened ball bearing vs. a steel ball which is not.  That was what I was asking about.

I was thinking about the ball bearing test recently and I suppose it ought to be a ball bearing, which should be hardened, vs. say, steel shot like for a slingshot.  Yes?

Improvised anvil for starters.  I thought that once I posted I did pretty well with the pic.  I paid attention to the file size, too.

48" forklift fork, six inches wide.  1 of 2 that came home with me.  I cropped and resized the pic, time to see how well I did that.

There are also other surface treatments for increasing wear resistance, abrasion resistance and more.  In particular, thermal spray coatings.

Thank you

Steve, I think he means at work, his job.

I am no expert but have been around machine tools for a while.  It may not be the appropriate method of hardening you are presently thinking.  There are methods like flame hardening which will harden just the surface to make it much more wear resistant while retaining toughness.  Pack carburization is another method.  Have you a mettalurgist or materials person to consult with?

What was the purpose of that signal?  Wake up?  You are approaching a populated area.

So you want to turn a rivet into a bolt?

A chainsaw would waste more of the wood and can be more difficult to control.  On the other hand, if you got one of those saws which require a buddy working the other end, you could make some nice, even cuts.

That is nice.

Drown out the anvil noise with some loud heavy metal music.

I dropped out of high school in my senior year.  I was bored with school.  I was smart enough to know that my future as a high school dropout could be not so good so I decided upon enlistment.  My Mom had to sign a waiver because I was not yet 18.  Happy 18th birthday in boot camp, Great Lakes Naval training center in January.

I got some much needed discipline and training, the most important of which is attention to detail.  They drilled that into our heads over and over.  That lesson has served me well in my life ever since.  I got to a ship homeported in Italy, as it was the Sixth fleet flagship.  So I saw quite a bit of the world and had some good times with my shipmates.

I made rank quite fast, E-5 in three years' time.  I have to admit that sometimes I was a bit of a jerk.  There were some older guys, late 20's or maybe even 30, that had gone the college route but still found it hard to make it in the civilian world, so they enlisted.  So I, at the age of like 20, outranked these other fellas.  Sometime I would say something like "Shut up Grandpa and swab the deck."  We were friends nevertheless.  So keep in mind that you will likely be working for some cocky people who are junior to you in age.  Not trying to discourage you, just to ready you.

Also be aware that they have a clever spin on the job descriptions.  The job that I was going to have offered "Working in clean, air-conditioned spaces."  Well, for the first year or two, it was clean because that was my work.  Not all of it, but more, since I was junior.  And air-conditioned meant that it was COLD.  We most often wore jackets in our workspace because all the electronics had to be kept cool.  They also promised mostly thinking/mental type work rather than physical labor.  Later that translated into what we would call "Sweating the load."  Worrying about stuff that really warranted very little worry.

I left after four years' active duty and did another six in the active reserves.  The GI bill really helped to pay for my college education.  I certainly was better prepared for excelling in my studies.

It seems to me that you have it pretty well together, so discipline and maturity you already have.  The will to be patriotic and serve is admirable.  I wish you the best and that you enjoy the camaraderie should you go that route.

Look for ASM Metals reference book, it lists the properties of different metals and their alloys.

Have you done a search for sawmills in your area?

Anthracite coal is the densest.

So since it has been brought up about Craftsman tools and the warranties...everyone selling that name now has their own unique SKU's for the tools that they sell.  So if you have one bought years ago at Sears, and try to exchange it at Ace hardware or any other retailer which sells Craftsman tools, they can decline the exchange.  It was not a Craftsman tool that they sold to you.  Take up your warranty exchange with the retailer that you bought it from.  Try to keep track of that!

Yes

Well, I was assuming that the middle of the sammich was stainless, making the bulk of it after grinding stainless.  Thomas disagrees, but I am still waiting on Phil's reply.  I asked because you are not going to harden stainless, just the high carbon steels.

The key thing about that paper is "edible oil production", as you can see on the second page.  They were not studying BLO products sold at the big box or hardware store.  Those may have drying aid additives which you certainly would not want to consume.

Nice work.  I have a question.  Since most of it is stainless then you forgo the hardening quench which you would do if it was all high carbon steel?

I was a bit skeptical about your claim Owen, so I googled it.  You are right about many common BLO products which are sold.  I did see, however, that there are some products offered without those heavy metal drying aids.  I guess that armed with that knowledge one should carefully choose which one to buy and pay attention to any additives present.
