That is a nice solid looking bed , great job. Just think although scraping in to flatness is very tedious but there wouldn't be precision machine's without the process in the first place. Another super interesting video, thank you.
"but there wouldn't be .... In the first place." Exactly! That's what intrigued me most and that's why I wanted to go into this journey despite its challenges.
I think what you are doing is absolutely fantastic! I would love to have access to a lathe and building one yourself is incredible and seems like a dream project (to me)! It is one of those machines that are just soooo essential to building our modern world, because rotational parts are so useful! Sadly I don't even have the space where I could put a lathe if I had one. XD I am looking forward to the rest of the series! On to the next video!
It is interesting how were made spindles and other rotary parts of the first machine tools in the world. And also how were the axes of the machines aligned
Glad to see your Whitworth method! I have a mill that I need to tune up the ways on, but currently dont have any fancy equipment to get me there. This might be 1 of several steps to that end. Thanks
Hi, this is quite cool, a lot of P's: Plan, Patience, Perseverance, Preshism, and Precision. I have a question, how far apart are the Ways? Is there a standard Ways distance measurement? Or more broadly, what are the critical dimensions between the Ways? Thanks for posting.
Love the preshism part 😄. Gap between ways is 70 mm. I calculated this considering the torsional force caused by the cross-slide and minimizing such torsion for better rigidity. So the only rule is how much rigidity you want to achieve. Thanks for commenting, have a good holiday season.
It's amazing! Actually I first met all over UA-cam how to make ways. Can you tell which sides you made flat? How did you get a ninety-degree angle between the sides?
One side, the thinner one, on each bar, for all the three bars. Then the remainder are made flat using the first one as reference. I didn't care to have a perfect 90 deg angle because for this purpose it is not critical, and being cold rolled the bars come quite squared though. Give a watch at the other video where I detailed this job.
Thank you! I used cold rolled steel. It has better dimensional quality but more internal stress so it is important to drill holes and make other mechanical work before making it flat.
@@AccidentalScience Did you get your steel stress relieved first? Or did you use as is? I was told that internal stress might be an issue, I just wonder how much of an issue.
@@Overclocked2300 to relieve stress the only way is to heat that however would warp the material. So, no I didn't relieve it, instead I made every mechanical work (boring, cutting, etc.) beforehand the work to make them flat. I learnt the lesson rhe hard way: At first I did the mistake of working out them flat and then boring, which led me to have to rework the relevant surfaces to make them flat again. One important note. Not all steel is made the same. I used high quality C40 steel for machining. I think it is somewhat pre-relieved. I had experienced some cheap cold rolled steel that warp just by the room temperature change.
@@AccidentalScience Thank you for the info :). If I have any more questions I'll be sure to contact you, but this is all good info. Its an interesting undertaking for sure! For those in the US reading this, C40 steel is about equivalent to 1040, a medium carbon steel.
Pardon my ignorance, but briefly rubbing the edges of those steel plates against each other for 2 seconds is enough to grind them so that they eventually become flat?
@@AccidentalScience Sure! At the 1:35 mark the metal is put on top of the other and a brief 2-seconds worth of rubbing occurs. The subsequent rubbings are about twice that length, but it doesn't matter whether it's 2 seconds or 10 seconds, I'm curious about how this repetition can cause it to become flat, because in my mind (again, pardon my ignorance as I know nothing about this) steel rubbing against steel at the small pressures we exert with our arms will take forever to grind it down to flatness. If you're doing it then obviously it works, but I'm very curious as to how this is possible.
@@anthonyortiz7924 oh that! No that operation is just to check how far from flatness are the parts. To steel is peeled off using a tool called scraper. I recommend you to watch my video titled "flat from scratch". (I'll look for the link and I'll post it here)
Il metodo Witworth se eseguito correttamente funziona anche se è lungo e tedioso. Tuttavia nel suo caso a parer mio lei ha usato troppo colore. Per raggiungere una buona precisione il blu (o rosso) deve essere appena visibile. Il raschetto poi va usato con più decisione e la riga deve essere bloccata (con una morsa di legno ad esempio) senza considerare il fatto che raschiettare l'acciaio non è proprio semplice come per la ghisa. Buona fortuna comunque....
The 3 plate method is to ring surface A to surface B, surface B to surface C, than surface C to surface A. Scraping the high area's between ringing the surface's. In the video it appears that A was rung to B, B was rung to C, but C was not rung to A.
Amazing how to make something extremely straight from nothing. have look at this-The 1751 Machine that Made Everything- on youtube, this machine started everything what we have today.
i have heard of the withwort method before and watched a chap making a surface plate..... amazing

Woao!!! What a beautiful job. Congratulations Man!!!
video´s just like youre´s are the reason I started crawling through YT :P

Very good one of the best diy lathes I have seen .

Sure! That's one thing intrigued me most.
Great work.
Thank you! Cheers!
Yes it is awesome the first standard is level then flatness
Glad to see your Whitworth method! I have a mill that I need to tune up the ways on, but currently dont have any fancy equipment to get me there. This might be 1 of several steps to that end. Thanks
I will post a video to show the process I have used.
@@AccidentalScience that would be terrific! Thanks
awesome method !!
Great work! Just subscribed :)
Good luck building your lathe! I know how the start of such a project feels like.
All the best!
Thank you mate.

You can use laser to check straightness and flatness, it is better accuracy.
preschism? lol. Great perseverance, man. Inspiring!
Thanks!
Coming along well! Feel free to put your lathe build videos on our homemade tools forum if you'd like more views.
Yeah ok thank you.
Keep up the great work
since there is no heat treatment of bed-ways, what is your strategy in keeping contact surfaces from uneven wear ?
AFAIK no lathe has hardened ways. Uneaven wear just happens. The carriage has brass contact bearing, though. It is softer than steel.
I recognize that cold rolled steel is allmost perfect out of the box. I mostly get deviation of 5µm per m.
Unfortunately was not true in my case, but it is still better than other kind of steel.
Very good 👍👍👍
Nice work man, keep it up I just subscribed to your channel and gave this video a tumb up.
Thank you.

Thanks for the answer! I watched the following video and realized how you did it.
You make really interesting videos! I'll keep an eye on your work!
@@Max-ut3qi Thanks bud, consider to subscribe so YT will not kick me out in the case I go below the threshold. Cheers.
@@AccidentalScience Actually, I did it a long time ago! Good luck!
4:43 "High pershisem" XD
Good video. i Hope your homemade pershisem lathe cuts well.
Yeah, I will see how much pershise will be :D
Did you use cold roll or hot rolled steel for your ways? Great video btw :)

thumbs up man! did you weighed it ? Looks heavy
Not too heavy. I have kept account of the weight of each part but not yet summed up.
Thank you mate.
great video.. thank you

"Briefly" and "2 seconds" are the wrong words here, absolutely. ☺
Please, may you help me understand how you reach such a conclusion?

It was. Look at the video where I addressed this method.
3:35 so is it flat or earth curvature. how you know xD i will measure is for known flat(earth curvature) xD
Where are the part one?
There is the link in the description.
What is sanduh?
?? ...sorry for my thick accent. I would like to help, what's the time mark you heard this?
@@AccidentalScience lol I'm just messing with you, bud. Thanks for the video 👍
@@joesosnowski7568 hahaha, ok.
Cheers.
what is preshism?
So you are impressed a human can make a piece of metal flat!
