How To Make And Use Precision Ground Flatstones

[@jasonmoore3557]

I've heard about grinding stones but i didn't know how to do it. So this has been massively helpful. Brilliant video 👏

[@daveticehurst4191]

Thanks for watching. So glad that I could help you out. Good luck if you try it yourself. Feel free to email me with any further questions. Regards.

Great to see you posting again Dave. Nice video - very imformative. 👍👍😊

[@daveticehurst4191]

Thanks 👍 Glad you enjoyed it. Thanks for watching.

[@MrCrispinEnterprises]

Great Video Dave, I loved the trick of using tool makers clamps on the mag bed as a work holding method.

[@daveticehurst4191]

Hi Crispin, had to come up with that idea as I could not find to buy the spring hold down plates that used to be around in the 70"s for holding non magnetic materials on a surface grinder. Thanks for watching. Regards.

👍 thanks for sharing. I didn't know they could be ground dry.

[@daveticehurst4191]

Thanks for the view. Just be aware of the dust in your lungs and over any nearby tools and machinery. Regards.

Hello Dave. Lovely to see a new video from you. Beautifully ground stones. Now I have a hankering for a surface grinder. 🥴👍😀

[@daveticehurst4191]

Go for it. You won't regret buying it. Thanks for watching. Regards

Brilliant video David. Very well presented. Precision stones would definitely be on my wish list. I know you can buy them from the US and Germany, but as you say they are very expensive, plus the shipping. Great to see your surface grinder in operation. Thanks for sharing. All the best Nobby.

Hey Dave, nice video. So good to see you posting again! I don't have a surface grinder but I have a trick that does a pretty good job, if not as good as a grinder would produce. I mount a diamond tipped core drill in the Bridgeport and use it like a shell mill to give me a flat surface. Works surprisingly well. Keep up the good work please!

[@daveticehurst4191]

Thanks for the view and comment. Your idea is fine for general use but is not suitable to make these stones. Not only is a rotary grind not realy suitable as it will leave swirls as you get if you have a steel plate Plough Ground, but also if the mill head is out of Tram, you will get a hollow surface. Regards.

[@mousemade1]

@@daveticehurst4191 True Dave. A good surface finish is possible with the right speeds and feeds but nothing in the class of a surface grinder. It does get them flat enough to do a great job on chisels and plane irons. PS - my mill is always in tram, you cheeky bugger lol.

[@DudleyToolwright]

[@Randysshop]

Hi Dave I hope all is well, I clean my stones with small ultrasonic cleaner and dish soap. I have also seen where you can use card board and WD40, I have tried that method and it works ok, The ultrasonic cleaner is better. Cheers

[@daveticehurst4191]

Hi Randy, are your stones Ground Flat Stone ? If so they would have no oil so cleaning is easy, either solvent or soapy water. What I was asking was how to remove the oil impregnated into new stones. Until that is removed they are not suitable to be ground and made into new Flat Stones. Thanks for watching and your comment. Regards.

[@williewheelspin9918]

Hi Dave I use a 50:50 mix of mineral engine oil and white spirit (used to be (paraffin).

[@daveticehurst4191]

Thanks for this BUT, Ground Flat Stone need to be used dry. New stones these days contain oil, my question was how to get the oil out. Thanks for watching. Regards.

[@craigbrown2183]

Excellent job! When can I order a set? 🙂

[@daveticehurst4191]

Thanks for watching. Email me where you are and I will see what I can do. First I need to find a way to get all the oil out of the new stones. Thanks for watching. Regards.

[@craigbrown2183]

@@daveticehurst4191 Thank you very kindly for taking the time to send me a set to Perth Western Australia. I can assure you they are excellent and have been used a few times with perfect results.

[@jonsworkshop]

Good to see you back Dave, and you certainly didn't get that sun tan from being in the UK😊. Often seen these used, never seen them made so that was interesting. Guess what type of wheel is now on my shopping list, hopefully I can get one thin enough for my surface grinder. I was surprised at the cut depth of 0.015" but I guess being diamond on stone, the forces are much less than stone on steel. Cheers, Jon

[@daveticehurst4191]

Hi Jon thanks for watching. Hope it gives you and idea to make yourself a pair. regards.

[@lydwood]

Thank you for sharing your knowledge, that was very informative. Interested to know more about the longitudinal feed arrangement you have added to your grinder, I can see a couple of inductive sensors which I assume flip a relay. What’s the mechanical side to this arrangement?

[@daveticehurst4191]

Thanks for the view and questions. The longitudinal travel is done by using a 12 volt car windscreen wiper motor with a crank on the output shaft. The crank arm has various tapped holes in so that I can attach the table arm to it to achieve motion. They are spaced so that I can get stroke of 4 inches to 12 inches. The cross feed is done by a stepper motor, the sensor you saw is a hall effect type that when a magnet passes it switches. I can slide some neodymium magnets along the edge of the magnetic chuck to suit the stroke that I am using, there is one at each end. As the table reaches the end of the stroke that I have set, I slide a magnet along until the light on the sensor comes on, this will turn off the inhibit signal on the stepper driver and allow the motor to run. There is a magnet at either end of the stroke. By adjusting the pulse duration the cross feed can advance from about 10 thou per magnet to about 50 thou at both ends of the table stroke. If you would like more information and some pictures, please send me an email to the address on the video. [e-mail] I hope this helps. Regards.

[@karlmansson8319]

Nice work! I’ve only seen people use those flexible combs for work holding before. Can you use flood coolant to grind the stones? To reduce the dust being kicked up? I’m tempted to try this myself.

[@daveticehurst4191]

Yes you can use flood coolant. Here is a link to a much better description on how to use and make them. I saw the combs 50 Years ago at my place of work. I have tried to buy some without any luck. Thanks for watching. Regards. kzbin.info/www/bejne/eoeviaanbNWcb7s

[@tas32engineering]

You could add a vacum shaped nossle made of gal so you could add a vacuum hose.

[@daveticehurst4191]

Thanks for the view. I did use a machine fixed extract nozzle when I made the next pair. I got fed up holding the hose by hand. 😊 gets tiring holding it and it also stopped me doing something else whilst it was auto grinding. Regards.

[@peterhadfield873]

Not being the owner of a surface grinder I had to find an alternative. Lapping three stones together using the Whitworth method produced three flat stones after a couple of hours work. Made a bit of a mess though :-)

[@daveticehurst4191]

Hello Peter, I am not too convinced that what you did to your stones that they would be classed as flat stones. When you rub them on a ground steel surface, do they glide easily or do they bite and scratch the surface ? With what you did by lapping, I wonder if the crests of the grit were removed at all. My diamond will defineately have removed the peaks. Thanks for watching and your comment. Regards.

[@peterhadfield873]

@@daveticehurst4191 Hi David. You may be right about the stone surface - I suspect that lapping the stones removes entire particals rather than planing off the peaks - rather like dressing a wheel. The stones are flat and don't dig in in the way that they did before lapping but I'm not sure that I'd describe them as gliding over the surface. thanks for your reply it was most helpful.

[@johnwilleford7715]

Good video Dave. Should you always use these dry or can you use oil? I don't have precision ground ones so I just spray mine with brake cleaner to clean them. One of the places that sells the ground stones here in the states is called 26acremaker. I have not contacted them about cost. I only know of them through other videos. I believe on Adam Booths channel. Thanks Dave.

$250-280 for two stones. Not cheap but worth it.

I find watching a grinder goin about its business oddly relaxing. You know these vids where they show a fireplace burning down for 8 hours? Do that with a grinder- we got a deal. I try to become a backyard wrenchmonkey, don´t have stones or a surface grinder. Just a shitty bench grinder that needs new faceplates and dressed wheels. Badly. I´ll shoot You a mail, I have a proposal in mind. Thanks for showing this, maybe I sometimes need it. Nice oilstones I´d like to have. G´day and kind regards

[@daveticehurst4191]

Thanks for the view and your story. Regards.

[@dizzolve]

how do I dress my diamond wheel

[@daveticehurst4191]

There is no need to dress the wheel. My wheel is some type of bonded diamond, it started off with 4 mm depth of diamond. I have made 12 sets of these stones and there is still over 2 mm left. The crisp sharp edge that you get when new, wears down to radiused corners and a slight crown in the center. As long as you pass the wheel fully over the stone you will be fine. I seem to recall when I was working that the diamond wheels we had were of the plated type and were dressed using a green grit block. Hope this helps. Thanks for watching and asking questions. Regards.

[@smpwaterjet8967]

Hi Dave - Great video thank you! Can you recommend a diamond wheel for this process? Which grit do you like? I have a small Taft Peirce grinder. will you share your email address?

[@daveticehurst4191]

Yes and yes. Email is on the video but here it is again [e-mail] Link to ebay wheel is www.ebay.co.uk/itm/234682927911?var=534397357029 and my size was 150 OD X 32 ID X 10 mm wide with a 4 mm thickness of diamond and 150 Grit. Comes quickly from China. Other sizes available from the same seller. Thanks for watching, hope to hear from you soon. Regards.

[@fearlyenrage]

use a ultrasonic cleaner that is what Robrenzetti does.

[@daveticehurst4191]

Thanks for the view. I saw him doing that but I beleive he used hot water and a soap solution. I just spray them with brake cleaner. Regards.

[@fearlyenrage]

​@@daveticehurst4191 well i assume higly that breakcleaner would work. When not I would go wild and use some washing soda. Then the oil would turn into a soap and could be washed away.
