My DIY Surface Plate

Тәжірибелік нұсқаулар және стиль

My DIY Surface Plate was made to assist me with some marking out processes, it can help a little with comparator issues but not by much. I made this video to explain how I made my surface plate in direct response to the many emails I have received asking me how it was made, this video should negate the need for me to return emails with the full process.

    Very good video :) In stead of diamond powder or paste, you can also use Cerium oxide.... It's available as a powder in many different grit sizes, and it's 90% as fast/effective as "real" diamond abrasives. And since it's so much cheaper, get a few hundred grams extra. It's great for polishing out things like windshield wiper marks on your car's windshield, removing smaller scratches and haze on a marble countertop, chrome details on vehicles and such things (where less hard abrasives like Aluminium oxide and such hardly touches the surface).

    One thought. Would sink cutout from solid granite countertops bonded together work as well. I've also wondered about the suitability of quartz countertop cutouts. Another UAE for them could be as the actual mounting surface used for a small benchtop milling machine. Bolting a mill to a wooden bench in my mind can lead to all sorts of alignment issues due to the wood expanding and contracting due to temperature and humidity iseues.

    I would recon anything with weight and mass would be ok for a base support on a home made plate, but I wouldn’t go trying to get it calibrated. if the bonding agent sticks. Humidity in my workshop is kept below 60% and all my biggest machines are sat directly on steel or cast pedestals then on to a wooden floor supported by concrete bracing.

    Non versare la polvere abrasiva sul piano, crei dei solchi profondi nella direzione della prima passata. Conviene mescolare la polvere con l'acqua e distribuire la pappetta in modo uniforme con un pennello. Non fare mai seccare l'abrasivo, si creano sfrisi, conviene usare al posto dell'acqua della kerosene o del petrolio. Il piano sotto tende sempre a diventare convesso, quello sopra concavo, la differenza fra le due curvature è pari allo spessore dell'ultima grana usata. il sistema di misura è corretto, solo che ti dovrai mappare la superficie per pinti discreti, pari all'altezza del triangolo di base ( le tre palline). ottimo lavoro

    🟢 Friend! I don't have a very thick stone (100mm). I have a lot of 20mm stones. I intend to "work" 3 large diameter stones (1000mm X 1000mm). I think 20mm is too unstable for a big rock like that. Can I glue several stones to get a more stable thickness? I chose a harder black stone in my region of Brazil. I also thought of making ribs in the shape of honeycombs between a sandwich of two 20mm stones. I'm building a universal milling machine, the stones would be to "right" the flatness of the dovetail guides and the coordinate table.

    Hi, I’m not an expert on surface plates as I pointed out in my video. However, one thing I do know is that the thickness of the plate is relative to the size of the surface plate. Not being an expert, I would expect a 1000mm square plate to be at least 100mm thick minimum. I would also expect that to maintain best stability, it would have to be in one piece, at the very least all made of the same material and the bonding agent to be as thin as possible. Temperature and humidity play a big role in the stability of of surface plates so the fewer variables in its construction the more stable the material. Sorry I can’t be of any more help. Regards.

    Hi, I was removing a wheel from one of my motorbikes, a stubborn bolt gave way unexpectedly. the watch hit a solid part of the bike frame. Cheers

    That was a LOT of effort. I wonder if there wasn't some way to move the plate around with a motor or something. I had a fuel tank that was rusted on the inside and I tied 4 cords to the corners and then hung it like a flower pot, poured in some tumbling media and some liquid, used a motor with a crank and tied to the side. Let it run and tilted it occasionally to get the top and corners. It looked great. I wish I had coated it inside with sealer because I looked inside the other day and it really needs it again. sigh. This was a good video and you explained everything really well. A definite thumbs up from me. I'll think surface plate every time I see a large piece of tile now.

    you cut diamonds into the surface to 'collect and redistribute' the abrasive. lapped your "B" & "C" plates (diamond side) together. then proceeded to NOT use that side to lap plate "A"?? what was the point of that work, then, just to use the non-lapped marble side on your surface plate!? you wanted flat bottoms?? what am i missing?

    Hi. I’m sorry for the confusion, the video was made to explain how I made my marking out surface plate to those viewers that asked me how I made mine. Using the two marble faces wasn’t a good example I admit but I had explained in the video that I used the other two identical surface plates in the garden…well my wife did actually, anyway I needed a couple of lapping plates to rub muck off some of the metal I often get given. Sand and water or oil can shift a lot of muck and rust saving sanding belts on the linisher and preventing clouds of dust and muck being thrown around the workshop. The marble side was used to show how I made the original plate. It’s not accurate but it’s brilliant for marking stuff out. My surface plate has a deviation of 0.001” good enough for marking out. Cheers

    I don’t think your measuring tool can prove that it is a flat surface, because it may also be a spherical surface with a small curvature.

    Quite right. That's why I won’t use it for anything other than marking out. As a marking out table it’s more than adequate. Cheers.

    true, but they should be 3 plates with the same constant curvature, which is impossible. That's why 3 plates are used. If you use only 2, it may happen that you generate a curve (one plate becomes concave, while the other becomes convex, complementing each other) But it is almost impossible with the interaction of 3 plates, with the turns and rotation of the elements, you can get a curved surface, since the 3rd plate should exactly complement the curved shape of your 2nd plate, which in statistical terms it is almost impossible, even more so if you consider that the 1st plate would have the opposite curve. That does not happen. A "rapidometer" makes comparative measurements, it measures the difference between one point and another, it does not give an absolute value of inclination as a collimator might do (which measures angles).

    Hi, they aren’t that cheap here in the UK. US to UK customs charges and delivery puts almost 50% on top.

    There's a cost / benefit equation in there, and if you want a verified accurate plate right now, sure, that's the way to go. However, if you're interested in the process, have exotic needs, or just plain don't have the money to buy a new (or even old) plate - as Paul says, they aren't anywhere near as cheap over here in Yurp - there's a lot of benefit to be had from rolling your own.

    sorry, but is piece, sorry 3 pieces of stone : too thin + glue + pies pumice +glue + thin piece granite - all have different temperature expansion (especially glue) & hogging under pressure . better, or correctly do that with 10 sm or more granite (not all, need hard, better diabaz or gabro). IMHO. process correct
