Lapping my Granite Surface Plate to AA Grade

My second YouTube channel that covers our fun explorations and traveling.

Lance is one of the most honest men I have ever met. He is a perfectionist. He has taken 6 or 7 Scraping Classes and in my 40, 000 students over 40+ years of training, Lance is in the top 5. I have had Lance assist / help me teach classes!. I am so lucky he came to my classes where he met Adam at a class we had at Keith Rucker's. Both Adam and Lance are A+ in my book!! Part of my scraping family. Anything Lance tells you or shows you is SPOT ON!!!

I worked in a 2A lab for the USAF for 12 years. This is exactly how it is done. Great job!!! Let the haters hate.

[custos]

It's almost like a person can be an expert in multiple areas given actual training and education

Phenomenal. Just in case anyone needed a reminder, a human hair mics’ in at an average of 4 thousands (.004) Adam’s plate is 65 millionths (.000065) from the highest point to the Lowest. That’s 61.5 times thinner than a single hair. 🤯

Guess people forget that the machinists trade has been around far longer than the certification process. So someone had learned how to do and do it right to even know how to set the standards. The negativity in people anymore is incredible. But those who can’t always want to try and bring those that can down to the only sloppy standard they understand.

I worked in the Metrology Lab at a helicopter company in the 80s. We used to joke about what is Mill Spec? It's where you measure with a micrometer, mark it with a piece of chalk then cut it with a hatchet.
You guys to true professionals in what you do. You did a great job and thank you for showing how it's done.

[bradwilson]

This is why YouTube is so great, very specific, very technical videos. Thank you both!

[johnsherborne]

It’s curious that Lance should feel the need to defend his expertise. He is clearly an intelligent gentleman, his varied talents show that. Why do folk think that to be paid for an expertise makes one more competent? In fact to do some jobs day in day out can take the edge of the pleasure of doing the best job possible. Where would American creativity be without gifted amateurs talents?

Whether Lance is a Veterinarian or a Baker or a Barber is irrelevant.... His pursuit of perfection is what counts!!! Keep up the awesome work Lance, and thank you Adam, for showcasing Lance's talent, and passion for a true artform!! 👍🏻🥃

Lance is amazing. What a treat to watch someone who strives for perfection and loves doing it.

Adam and Lance. I really liked this video because. when I was in the helicopter component overhaul industry, Our plates had to be inspected min. off once a year. I saw these guys come in, and do this just like you did lance, and watched them lap also, but I never knew what they were doing when they took these readings. So this was very educational for me even at 72 years old, I now know what they where doing. Adam& Lance Thank for showing this I really learned something. Yes we also used Windex, to clean the plates before we took measurements.

Lance is a class act. I love when he makes it into video's. That plate for 50 bucks, now AA is just awesome. Lance has some great knowledge and passion for doing this. And he actually enjoys it. Great hobby.

People will always troll you. I am a Combat Veteran, FAA certified A&P mechanic, large business manager, and Registered Nurse in an ICU. I mine, cut gems, make jewelry, am a member of a college engineering club, Nobody is ever just 1 thing and you don't have to earn a living at it to become proficient. Ignore trolls and do what you do.

I don't know how i'm going to explain to my girlfriend tomorrow that a relaxing one am activity is watching a one hour video of two men leveling out a granite plate and how important an object like that is to modern civilization

[hyn]

"let me show you what true level really is Morty..."

[sciloj]

There's the term for it: "credentialism". People these days rely too much on someone's diplomas and certificates since they are often incapable of assessing the actual substance of the work done or the logic presented.

[tomoakhill]

I have had the pleasure of seeing the "gauging lab" at a GM auto factory. It was a "clean room" that no one was allowed to enter except the certified technicians. The oil on your had would ruin their plates. It had large window so you could see the surface plates. It had an air-lock, and a huge HVAC to make absolutely sure that the interior of the room had "adequate climate control." The instruments in the room were used to calibrate the gauges that were used to calibrate the gauges that were used to check the parts being made.

[billjohnson]

Looks to me like Lance is a natural at this, and has the money to buy what you need for it so yeah I would definitely trust him.

[gamemeister]

74 millionths! .74 tenths! Across a 2'*3' surface! That's amazing.
