My DIY Surface Plate 

Hi, thanks, i’m affraid that I fall asleep watching them now… must be an age thing. LOL..

It's across :The Pond: 👍

Hi, glad to be of service. ATB

Hi, thanks, glad you’re happy with the content. :-D

Almost Machining Hi, thank you, thanks for watching.

Hi, thats a good tip. thanks.

Hi, thank you. Happy new year to you and everyone.

Hi, thanks for viewing, regards

Cheers mate.

Hi, thanks. ATB

Noneof Above Hi, thanks for watching

Hi, thank you, I’m glad you enjoyed.

Skillful Man hi, thank you, thanks for watching.

Hi, thank you. Cheers.

Thanks for that, I am unable to do weekly videos because, for me to get 1 minute of youtube video can take unto 5 hours of recording... I've only got a toy camera!!!

@@Thesheddweller Is the issue the size of the sd cards you use? I have some larger capacity sd cards i can send you for free if they are of use to you?

@@thomaswilliams Nah.. I currently have 300 odd Gb of sd memory, and I store everything on my computer hard drive as soon as I can. The truth is a bit more personal than that and it only allows me a little time to spend in the workshop. thanks for your very kind offer though.

With enough patience the Withworth 3 plate method will produce top quality plates even in home shop.

Hola, gracias, gracias por vernos.

Thank you, cheers

Hans Hi, you're welcome, thanks for watching

Stevo Smiff Hi, thanks for watching.

Hi, thanks for your kind comments, thanks for watching.

Hi, thanks.

great, have fun. cheers

Hi. Yes that’s true but, my DIY lapping plates are really for cleaning old and dirty metal that’s been given to me. I don’t like having muck and dust flying around the workshop that I get using the linisher or rotary wire brush. Cheers

Hi thanks. cheers

You’re welcome, Thanks for watching.

А класс Б это сколько нулей ? ( В СССР были плиты 3, 2, 1, 0, 00, 000 класса)

Hi, yes that is true but, I think the liquid and abrasive material can also sucked out of the grooves as the plates passover each other, don’t you think?, cheers.

Ciao, grazie per la visione, grazie per il consiglio, molto apprezzato. Saluti

Hi, So did I.

Wow, nice, have fun.

Obrigado, lembraças.

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.

@@Thesheddweller Thank you for this channel and the discussions y'all are having. The passion is felt. I'm a casual, but excited to learn more!

@@mturallo Hi, thanks for your comments

Hi, thanks for watching. They probably make the mink run like a bugger for an hour or two in an exercise wheel.. :-D

@@Thesheddweller LOL!!! I'm hoping it's the oil they use to stop the mink from squeaking - made *for*, not *from*.

@@fredgenius Well they definitely aren't squeaking anymore. Best not to google it.

Hi, thanks for your comments, I've only got so many heartbeats left before I get put out to pasture, and I've already got so much to do. cheers.

Hi, I knew a bloke who made very special clocks in his cupboard using a small lathe, mill and one or two fold out benches and vices

Hi, it is true that is why I only use it for marking out. I have used it for gauging stuff before now but, that was before I had my cast iron surface plate, that warps if you walk past it but it is more accurate than the surface plate I made.. cheers

Hi, thanks for watching. I still use mine for marking out stuff… Cheers

crikey, lasers... I've only just got used to using a simple rule...Cheers

Because I’m thinking of using a solid piece of granite, which would be more durable than marble. My biggest fear is that granite and marble tiles would be too brittle. I’ve got access to granite slabs at least 2” thick, which in turn I can also use for doing leather work.

if you have a precise surface grinder it should be

Hey, thanks for subscribing, cheers.

Hi, it couldn't be any worse, could it.

Hi, I know. I have a cast plate now for my workshop, but I have to get it verified before I can use it.

@@Thesheddweller There's nothing to stop you verifying your own plate if you can get your hands on a 0.02 or so machinist's level. You could use teh results of that to do localised honing on your plate to move it up a few grades pretty quickly. My plate was made from a piece of granite kerbstone, by localised honing only, which is a much longer process than the 3 plate method.

@@wibblywobblyidiotvision thats worth looking into, when I get some time I’ll look into that. cheers.

@@Thesheddweller I've linked the software I developed for mapping my surface plate on (IIRC) the second of my videos about it. It's jvascript, should run anyhere a reasonably modern browser will.

Hi Silvio, there are more skilled surface plate videos out there than my offering, I would suggest watching them also. the thicker the stone the more stable the material.

Да Да

Hi, thats what I like to see… someone having a go, good on you.

@@Thesheddweller I made (I think) a unique surface plate. The concrete plate was not tool-friendly, so I used epoxy and fine aluminum oxide abrasive powder slurry to coat the concrete. I used a paint roller to apply several coats, sanding each coat. It leaves a finish that looks "hand-scraped", and ground steel tools just glide over it. Couldn't be happier. Thanks for your inspiration!

Hi, thats also good enough for making out purposes. regards

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.

@@Thesheddweller Gratitude friend!

@@silvionovais2504 You are very welcome.

Hi, No… he gave up cos the tea mug was dirty.

Yes

Hi. yes,.. you're right, but I don't have one... Thats why I Gave it a (Class 'E'.. Maybe) but its more than good enough for marking out. Cheers

Привет, Моей кружке всегда удается собрать какой-то осадок, но не в этот раз. Ура.

@@Thesheddweller кроме индикатора (репитометра) как то еще плиту поверяли, (проверяли) смотрели ?

@@guliwer1713 Мне очень жаль, что вопрос, который вы задали, выглядит странным при использовании моего переводчика. поэтому примите мои извинения, если это выглядит неправильно. Поверхностный датчик (репетометр) работал, как и следовало ожидать, учитывая, что это бодж. С уважением.

@@Thesheddweller переводчики они такие .... х**** поймешь че напереводят .... what else did you use to measure the Surface Plate какие еще вы использовали приборы для измерения (ru) what other measuring instruments have you used Surface Plate (en)

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

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.

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

Well… I’m not qualified to certify it. regards

But the class of the shed dweller himself is undeniably AAA, class act all around. Good work shed dweller, i like your style.

Hi, I agree, but I don’t know anyone who can boast having any equipment to measure the error, let alone constantly control temperature of their machine shop environment. regards.

Im sorry to hear that. Your knowledge on surface plates is surely far greater than mine but, I do say I’m not trying to teach anyone how to do stuff, I merely show people what I go through to to achieve my goal. regards
