The best place to find genuine experts is to look at the comment section of a UA-cam video, then to verify their expertise go to the commenter's home page- Only the real experts will have "no content"! Awesome video as always Brian!
If someone told me that RCA made a hardness tester, I wouldn’t have believed it! It looks similar to their ribbon microphones. On a convex, the reading will be lower than a flat, and on a concave, it will be higher.
Just like I was saying last time, you where turning real slow (I had in my mind1400 not like 400 rpms) and you where getting some purple chips I knew that was a good sign. You have a good oven and that ATP stuff works good . and that Rockwell b/c tester very interesting on those lathe ways and mill table and the comparitive nature of the Rockwell tester
I would be interested in seeing the hardness of the working surface of the tappet, where it contacts the cam lobe. Also it would be nice to know exactly how that tool works. I have a portable hardness tester that seem to operate in a similar manner but does not seem to work. My tester is by Newage Industries Inc. Jenkintown, Pa.
If he'd hardened just the face, or done it in a separate process, testing would be a good idea. However, since the entire tappet was hardened with a consistent technique, all over, in the same process...there's no reason to think the face would be any different to the multiple points he tested on the shaft.
Great job. Nothing like proving your point to Doubters. The good one boys have gotten it done for years with knowledge gleaned from experience. To many today rely to heavily on technology.
Agreed...but with a caveat. Too many who _think_ they know what they're doing - don't. So it's always best to confirm what you believe - no different to when you mill a part, or machine it on a lathe - then check the final dimensions with a micrometer. Better safe than sorry.
Funny how a tool branded as Radio Corporation of America is made in Japan. What’s even funnier is that they made it look like an old studio microphone. Great find.
Great test Brian. I love that you tested your work on video. Of course anyone who watches your videos knows you are not lacking in the balls department. Would have loved to see the repair on the tester it must have been interesting
Wish you were closer Brian, I'd love to run a check on my Chinese "flame hardened" ways just to see the difference between proper Monarch quality and highly suspect. That tester have a aged cheese scale range? :-)
Portable....!!! may actually be practical in the bedroom, mainly since there is a C scale on it... lol You got a good point there, my Rockwell tester doesn't stretch enough to measure the ways on the lathe, I'll have to cut off a pice of lathe to bring it to the tester... Sigh...!!! Sure looks like a microphone from the 50's, hope it also sounds good... Cheers
Diamond indenter for the old diamond cutter, maybe I swll stick to using a friend to check that. Looking forward to you checking the ways on your lathe :-)
Brian, thats a nice piece of test equipment. The portability of it makes it especially valuable. I hope you didn't buy it to shut up the naysayers. They'd complain if you hung'em with a new rope. I'm glad you had those standards to compare with. Hard to find fault when your machine checks out with them. R
I have wanted a way to scientifically verify my work on my own so it just happened to work out and since it was questioned just thought I would answer it. People can't learn unless they ask so i don't think they were naysayers, just questioning.
Thanks, For the vid. I like you, farm and work on everything in my shop also. I get so tired of the negative comments from the uninformed.There is a crowd of people that have never accomplished anything and never will.Keep up the great work.
Since you've presumably dug into the mechanism while fixing it, is it something that could be shop built? I've been waffling over buying a Leeb type tester, but even the imports seem expensive for what it actually is.
Yeah it is pretty much a couple of springs, and indentor and a dial indicator. The indentor would be the hard part and then you would have to calibrate some kind of scale for it. You would need lots of samples to test to develop the proper scale vs indicator needle movement.
Hello bcbloc02, I'm picking one of these up. It has the same issue as what you mentioned with the gauge needle stuck in the 80 range side. How did you get yours to work? Great video by the way.
@@acxelalegria I didn't take any of the face apart. It is pretty much just a dial indicator so if you have worked on one of them inside this is the same.
how does hardness testing work? its something ive never been taugh as only time i hardened something was when i was 16 and it was a hammed we made in machining class and those were not tested
Def interesting Brian. Cool little addition to the tool box. I didn't even know there was something like that out therre, portable, simple. Thanks for sharing
Air cooling me friend ... air cooling ... Look at the concept of mr. Gotteswinter doing it .. low hardness but hard enough .. female inspector would accept :D ... !! It's all about hardness not elongation or E modulus! :D
Thanks for testing the lathe bed. I've always wondered how hard the flame hardened ones were. No wonder they stay in such good shape. I had no idea they were that hard.
Didn't you say that your lathe can't run the recommended surface speeds for carbide inserts in the hard turning video, Brian? Most hard turning is done at high speed, low feed. That's why he doesn't get the sparks/molten material coming off, people. Doubters will be doubters I guess lol. Your process seems dialed to me. Well done, Sir.
People can't learn unless they ask so i don't think they were naysayers/doubters, just questioning. I was fairly confident in my methods but only way to know for sure is to check. :-)
Holy smokes! What kind of steel even gets to 90 rockwell? That had to be in B scale right Bryan? Thanks for another great vid Edit: Referring to the test block in the beginning not your mill table that you said was 90 B scale. Also, not sure why those people were expecting to see glowing glowing swarf when you were turning because you said in the video that your lathe won't spin up that fast and get to what that insert really wanted.
WOW, such a nice test tool. Most think of RCA as electronics, not test equipment. Glad Baily approves. You can now give documentation for hardness on projects.
What's with all these comments? Someone sees a possible issue in the process, Brian checks it out. Whole reason you share videos or anything really, to get different views on what you're doing. It's real easy to get your quench oil too hot to properly quench, especially when you're using a smaller amount than you've used in the past. Past a certain point it just boils around the part leaving a nice envelope of vapor that doesn't conduct the heat quickly. Just like with w-1 drill rod, try and use water that's 190F and your parts will come out nowhere near glass hard.
People can't learn unless they ask so i don't think they were naysayers/doubters, just questioning. I was fairly confident in my methods but only way to know for sure is to check. :-)
Want to make it clear on the last video i was not questioning the hardness just the shape of the contact surface. That tool is a find! If you look at quality aftermarket lifters. Every one will have a little mark on the surface that touches the cam. Hardening is part science part art and part luck. Seems like you could make a simple fixture to drop the lifter in (a piece of steel with a hole drilled in it. ) to check the lifter face. one of the variables is depth of the hardening and being fairly equal in different locations. Ps I want one of those

Nice little unit to have in the shop! Good job on the tappets!

"have my hardness checked by a friend" LOL
Shockedbywater Still owe me 50 bucks lad. Don't know why you want a man checking, but I'll take 50 for 2 seconds anyday.
Yes there are peole that have friends
definitely a cool tester, sure beats my non portable . stick it to the critics.. nice video
Brian, that was a very interesting test, guess you showed the daughters. Love your videos.
As long as they are legal age I guess I can show the daughters my hardness! Lol
Very valuable instrument, very cool.
You will get good use from that.
I would be interested in seeing the hardness of the working surface of the tappet, where it contacts the cam lobe. Also it would be nice to know exactly how that tool works. I have a portable hardness tester that seem to operate in a similar manner but does not seem to work. My tester is by Newage Industries Inc. Jenkintown, Pa.
Face and shank are the same hardness, I checked some. Also the material thru hardens so it should be consistently the same throughout.
Interesting kit. Never seen one.
It should more than meet your needs
What is the hardness reading on the face of your tappets, isn’t that the face riding against the camshaft? Nice tester, thanks for making the video.
If he'd hardened just the face, or done it in a separate process, testing would be a good idea. However, since the entire tappet was hardened with a consistent technique, all over, in the same process...there's no reason to think the face would be any different to the multiple points he tested on the shaft.
They are thru hardened so faces check the same.
Nothing like having a spare axle in the driveway’ just a quick swap-out and back on the roads~>
Keep spares of everything, could need it at any moment! :-)
Look at all that blank space they left on the dial...they coulda went to 90 ;)
Yeah you would have thought they would have expected people to need that portion of the scale all the time! lol
With that logo and look, I half expected to see the glow of vacuum tubes through the side vents :-)
Nice tester Brian. Nice to see you casually give the middle finger to the keyboard naysayers. Good on ya
Great job. Nothing like proving your point to Doubters. The good one boys have gotten it done for years with knowledge gleaned from experience. To many today rely to heavily on technology.

They used to always make us "prove our work" in engineering school. Life is no different. :-) lol
Nice piece Brian!
ATB , Robin
Funny how a tool branded as Radio Corporation of America is made in Japan. What’s even funnier is that they made it look like an old studio microphone. Great find.
That is a cool new toy, I would be testing everything too. Well made back then.
Great test Brian. I love that you tested your work on video. Of course anyone who watches your videos knows you are not lacking in the balls department. Would have loved to see the repair on the tester it must have been interesting
RCA.....Radio Corporation of America........Sorry, I couldn't resist!!!!!!!

Keyboard cowboys always have 'something' to say. And they never offer, "Send a sample to me, I'll check it on my portable hardness tester" haha.
Less than $259. Excellent deal, Brain. Thanks for sharing!
Ah...vindication. You *were* right all along. Thanks for the video.
Portable....!!! may actually be practical in the bedroom, mainly since there is a C scale on it... lol

Nice tester. I like it.
I believe ya Bry, no doubts on the quench, no need to provide it. Cool hardness tester though. "My hardness checked by a friend" HaHa!
Hi Brian, now that you have a hardness tester you can check the next knuckle head guy and see how hard his brain really is!
nice to confirm what you knew already - good job!
And there goes all the eBay prices on portable hardness testers. Ha.
I thought they were already high!!!
I can't believe anyone would doubt you Brian!! Great job!
COOL TOOL and good info on Monarchs.
Brian, thats a nice piece of test equipment. The portability of it makes it especially valuable. I hope you didn't buy it to shut up the naysayers. They'd complain if you hung'em with a new rope.

Not sure why anyone would doubt your methods, well studied & experienced. Nice work sir !
That is a very good find. The box is even cooler. I took the high road here despite my 12 year old sense of humor.

what a cool tool with a side order of I told you so :)
That's a very nice addition to the shop.
Thanks man!
Since you've presumably dug into the mechanism while fixing it, is it something that could be shop built?

1,100 people already watched this morning. It's only been out for an hour.
If it was 10 times that it would be like an Abom79 video! lol
Nice job, That RCA Hardness tester looks like a microphone from the 50s.
That was my thoughts too, was looking for the wire to go to the amp LOL
Great tester too. I like to learn and this is a good spot to learn! Thanks Brian
Hello bcbloc02, I'm picking one of these up. It has the same issue as what you mentioned with the gauge needle stuck in the 80 range side. How did you get yours to work? Great video by the way.
I took it apart and cleaned it.
@@bcbloc02 thank you. Did you take apart the dial and was it complicated? I have the dial off the body.
@@acxelalegria I didn't take any of the face apart. It is pretty much just a dial indicator so if you have worked on one of them inside this is the same.
Cool! I just purchased a digital portable hardness tester (not cheap!). Great tool to check your workmanship.
how does hardness testing work? its something ive never been taugh as only time i hardened something was when i was 16 and it was a hammed we made in machining class and those were not tested
Brian's tester is using the Vickers method, which is one kind of indentation hardness tester. en.wikipedia.org/wiki/Hardness
Brian nice job. Nice little addition to your tool collection..
Yep glad to have it!
What did you have to fix on it?
The indicator and travel mechanisim were gummed/frozen up.
Definitely a cool tester to have.
How do you you know when your mill is big enough? When you can do a presentation on the table and still have room. I love that old American iron.
Def interesting Brian. Cool little addition to the tool box. I didn't even know there was something like that out therre, portable, simple. Thanks for sharing
Air cooling me friend ... air cooling ... Look at the concept of mr. Gotteswinter doing it .. low hardness but hard enough .. female inspector would accept :D ... !! It's all about hardness not elongation or E modulus! :D
Useful bit of kit that. Proved that Baily was right all along!!
Thanks for testing the lathe bed. I've always wondered how hard the flame hardened ones were. No wonder they stay in such good shape. I had no idea they were that hard.
Nice info, Bob.
Enjoyed!
a lot of good steels will almost air quench, you dont need 100 gallons of oil!
Nice video thanks for sharing. Hey Bailey
I enjoyed that demo. things I did not know nice tester. hi Bailey.
well, it says that you know what your talking about when hardening steel brian well done sir and not seen testing before now.
Nice little addition, Keep up the great work.
Nice addition to the shop, very versatile. Good score
Nice work Brian! Matt C.

if bailey is happy that's good for us
Holy smokes! What kind of steel even gets to 90 rockwell? That had to be in B scale right Bryan? Thanks for another great vid

Also, not sure why those people were expecting to see glowing glowing swarf when you were turning because you said in the video that your lathe won't spin up that fast and get to what that insert really wanted.
I can only speculate that it is Tungsten carbide that is that hard.
Pretty cool stuff!!
No doubt in the tappets or Baily approving. Now to retrieve the HBM! He'll approve it too. Snow here this a.m. Pretty but gone pretty quick.
We had snow too, maybe if it is dry tomorrow I may try to make a move..........
Just spitting snow here this a.m. but NOW you're talking!
FIRE THAT CUMMINS!
I seen files that would check rockwell hardness one time different files would file a higher or lower rate
Yep those exist to for a good way to estimate hardness as well.
well done brian
Nice work!
Brian, can you explain what you did to fix it please? Thanks,
Joe
I took it apart, cleaned it, oiled it and recalibrated it. It pretty much was stuck/frozen up from sitting.
Thanks!
Nice tester.
WOW, such a nice test tool. Most think of RCA as electronics, not test equipment. Glad Baily approves. You can now give documentation for hardness on projects.
I never knew they had an industrial instruments division. I guess they probably did build oscilliscopes and the like though.
I know. Electronic yes but Mechanical. You need a clean room in the shop/doghouse for that and the optical caparitor
If I could get the granite table in Bailys couch room I could make that my "lab" controlled clean room. :-)
Hey if you can rebuild that barn you can figure out how to get the granite table into Baileys couch room, but you may have to reinforce the floor!
Hope your doubters at least apologize.
What's with all these comments?
Someone sees a possible issue in the process, Brian checks it out. Whole reason you share videos or anything really, to get different views on what you're doing.

Brian, I just asked a question of how. Didnt mean to start a war. notice thumbs down? Never could affort one. B 10, others 0.
No worries! People can't learn unless they ask! :-)
