Viewed your own video earlier today, Tom, can you tell me what causes the wear as I am not familiar with the uses of these plates. Greetings from Scotland.
Hi James, The wear on granite surface plates comes from hardened gages with dust underneath them sliding around on the surface. Add some lapping with sandpaper and bingo plate wear. Keep in mind we are talking very small amounts but when the plate is your primary flatness reference you can quickly get into trouble. Thanks for the comment. Cheers, Tom
Hi Stan, Thanks for taking us along for the tour. It's always great to see how something is made. Those surface grinders were incredible! Its pretty impressive that they can keep the surface flat on something so big. Very interesting place. Thanks for the video! -mike
Awesome! That was informative and entertaining Stan. Great to see how the plates are made. Your buddy there really knows his stuff. I was jealous seeing all those plates everywhere. I need one in my shop!! Thanks for sharing that your with us! Adam
I dont mean to be off topic but does anyone know of a tool to log back into an Instagram account..? I somehow lost the password. I would love any assistance you can give me
@Mathias Steven I really appreciate your reply. I got to the site on google and I'm in the hacking process now. Takes a while so I will get back to you later when my account password hopefully is recovered.
Hey Stan, Excellent interview, very informative, I learned a lot about surface plates! Looking forward to seeing your new plate in use! Really enjoyed the field trip! Ray
Wow very informative learned a lot about surface plates I have a cast iron plate but would love to have a granite one, perhaps one day I can wish. Dave
excellent video! Standridge just came up to Sacramento and did some plates for a collaborative event Bob Korves, Randy Richard, (Razor)Ray Goff and i all had our surface plates re-calibrated. it was very reasonable and they did excellent work!
Hi Stan, This was an instructive tour, learned a lot about plates... Happy to learn that a American made plate is so much better, I'll enjoy more of my 36 x 36 x 6 Rahn plate. There were parts that I really had problems to hear and understand, about the maintenance of plates, if it would be possible to put aside a few minutes in a future video to resume at least that subject. Pierre
Excellent! That was extremely informative, Stan. Thanks for taking the time to make the video. I'm suffering surface plate envy after seeing all those big plates. Looks like you took home a really nice size one. Who'd thunk they use a Mag-lite as a light source for checking flatness. Cool!
This was a great video with lots of good info. I really enjoyed seeing that big brother Thompson grinder to mine. That machine was big but he was talking about 10ft plates, where was the one they do those on? Even that Mattison didn't look that big. Not even my house would be an acceptable climate for anything beyond an a grade plate I don't imagine.
That was great Stan. Learned something new as usual. One day I hope to get a shop big enough to get a good surface plate till then il just drool over the ones here on RU-vid.
Hi mate. That was very interesting. I wish I could have understood a little more of what was being said, but I'm sure you did your best. Like you said, these seem very nice people, quite contrary to the people that I met in LA. This guy was knowledgeable, and became more interested when you asked him meaningful questions. Thanks for taking me along.
True story. I used to work for a company that produces such high precision plates and high precision spirit and electronic levels in Switzerland. One guy, responsible for the machine shop, had an old tombstone from one of his family members. Where I live, the graves are not for eternety, so you'll have to deal with such situations after about 25 years. The tombstone was from this high quality black granite (Impala) and in perfect condition. So he sold the stone to the owner of the company and the stone was used then in various setups for internal use. The inscription was still there, they just mounted it in such a way that you couldn't read it.
That was a fascinating video and the fella was super helpful but the audio was so hard to hear i missed most of the detail ..id love for you to go back and do a detailed version of how they flatten to tolerance and more on their machine techniques
A great example of your creativity. It is a interesting and informative video! A side note on McMaster-Carr taken from Wikipedia: "The site ranked third in a large study performed at Stanford University about trust and credibility, just behind amazon.com and bn.com. The author concluded "The surprise comes in seeing who landed in third place: McMaster-Carr-a relative unknown entity compared to others who ranked high in this category. The McMaster-Carr site has relied on its own merits-not on a public relations campaign or a big reputation-in conveying high levels of credibility"
Oh lol the old wifes tales about leaving the casting to "season". Sure, it might have been done due to expense of heat treat, but it really has pretty much zero effect on internal stresses or metal structure inside the casting. I rememberseeing a study about this and they showed that it is at maximum 10-15 % that you can lower the internal stresses by just "seasoning" outside, while a proper heat treat gets almost all the stresses gone in a few days (big castings). The "real" reason you see castings laying outside is because they don't go out of tolerance sitting in the rain and usually there just is no space inside facilities to hold large amount of stock waiting to be machined.
Great "field trip" Mr. Skee. Bet your wife said you were a inch longer that evening. It's all about a rock-solid, dead-nuts, absolute, last-word... standard ... to base everything else from. Everything else is a cake-walk form there. thanks for you time.
Greetings, 1. Could you explain or make a video on the mounting the surface plate on three point suspension with 20% style 2. what was that white bottle? Could not understand due to the background noise regards
Stan, Granite in Escondido? Who knew? Anyway, thanks for the interesting video. I guess you should keep your shop air conditioned during the summer if you live in a hot climate so your surface plate with me nice and comfy. I guess the take away from this video is to be kind to your surface plate. Never take it for "granite"! (No more puns . . . I promise!) Have a good one! Dave
I wish I would have thought to ask you to ask them before, but living up here in Illinois and having a shop which isn't regulated for temp or humidy all of the time, what affect does that have on a surface plate? I know the accuracy will not be there based on the video information, but if it was in that condition, would it wear down or break if it might freeze in the winter?
ILGopher He actually talked about temperature and center deflection, 20 degrees will equal .003 edge to center over 24", convex when cold, concave when hot, totally flat @ calibration temperature. As far as extreme temps damaging the plate, it would have to be terribly wet and terribly cold to split a chunk of granite. Sorry I missed your comment earlier. Z
Very informative! But someone needs to tell that young man to either lose the hat or wear it correctly. He sounds very authoritative and professional, but it's hard to take seriously someone who's wearing his hat like a 10th grader. There does come a time when you should leave the things of childhood behind.
