Thanks for making such an inspiring video I really love seeing these things because it empowers me to do bigger things when people tell me it’s not possible.
@Anthony Lovell. Yes, that's what I thought - a quick prototype to check, then get some contraption to sort out the lathe. Anyway, it's cool. Maybe they have enough patrons now to send the lathe bed out for a regrind, or buy a lathe with unworn ways.
Cool! I almost forgot that your aim was to fix the lathe two years ago! I am wondering, how did you manage to get two linear rails to end up on the same plane? What is the process for that?
You can check for equal distance (DTI base on one rail, probe on side of other rail) and for relative twist between rails (DTI on top of other rail; done for both rails). This doesn't guarantee flat (could be a spiral if both rails twisted the same), but given the unlikelyhood of a spiral, you're very likely to get a decent plane.
Nice!!! I like the bit at the end about learning new skills. That's how I go into most of my projects. What I think I'm building to start with normally ends up looking very different by the end, mainly because I have no idea what I'm doing and learn while I'm making. I have learnt so much in my life using that approach....... things do take longer that way and quite often the project doesn't move forwards for long periods of time until I work out how to overcome the next problem. Fun times 🤔😊
Hurrah, I can now start to watch other videos and catch up with my other subscriptions. Just binge watched the lathe and then the surface grinder. Brilliant job, I learned a lot watching these, thank you!!
Hi just saw your amazing video. I love it! I'm a machine builder too but at the lower end. I'm building a mini Deckel FP1 with similar features, started 5yrs back yet taking ages to complete with many distractions. Anyway will follow my passion like both of you did, thank you for inspiring people like us.
This was truly amazing. I admit even though I couldn't wait for each new episode, I must subconsciously have had my doubts about you actually succeeding in this project, because I am blown away to see it actually completed. Good job, I am thoroughly impressed
All this because they acquired a fantastically worn out lathe. No criticism. I admire your tenacity and your creativity. Well done sirs. Will absolutely keep watching.
Totally impressed by every aspect of this video, heck the whole damn project. Sound editing is very good, keeps me entertained with the project. keep up the cool work.
Can't speak for them, but I would have chose the BLDC as well. Easier/cheaper to speed control, more compact, better power factor, superior rotor cooling, lighter weight and less expensive. If it makes you feel any better, the BLDC is surely also 3 phase. The down side of a BLDC here is you now have magnets near floating metal shavings.
@@codycarse Not quite. An induction motor does not use permenant magnets, which can be ideal when the environment consists of floating ferrous metals due to, say, grinding steel.
Typically it wares into a taper and you grind advancing in one direction. So as you grind, you start out with the leading edge doing all the grinding. Over many passes it will eventually get to the point where its cutting on the trailing edge, but long before that you should redress the wheel, which will square it back up. It takes a lot of grinding to get it cutting on the trailing edge. So the effective cutting diameter remains the same. I think Tom Lipton explained it better in one of his videos.
@@lordgarak I get what you are saying but I stated my question wrong. Over the course of time the loss of material will change the diameter of the wheel. So let's say if you are trying to grind a 12"×12" piece of material on one side the "X" it will be higher than the other end. Even in the "Y" axis. I will look up that video you referred to. Thanks for your reply.
@@CJMorin The effective diameter remains the same as all the material loss happens on the leading side of the wheel. If your grinding properly your only stepping over something like 0.100" on a 0.750" wheel. That first 0.100" of the wheel is doing all the work and receiving all the ware. After a few passes the next 0.100" starts working harder. So the third 0.100" is bringing it to final dimension. You can complete a fair number of full passes across the part before you ware across the entire wheel and have to redress(depends on the material your grinding and the properties of the wheel). After redressing you would take a light cut and measure your work to see exactly what height its cutting at. Their machine can only grind something smaller than something like 12"x6".
It is on top of a cheap moving tool cart. It really needs to be on a solid surface. The frame of the grinder is perfectly sturdy for the forces being applied, but I have got to believe that much wobble is going to loosen something.
@@bluedeath996 I remember in a previous video, the surface quality of the part was extremely poor. Hobbyist don't understand that a machine structure is designed for damping, not for rigidity under elastic deformation.
@@meocats If damping is the goal, why are machine tools made from giant blocks of plain, cast iron? Composites usually have superior internal damping (along with a lot of other nice potential features), can be engineered to have VASTLY superior internal damping, and can be made more cheaply than cast iron. Also, there are a million-and-one add-ons to fix what internal damping doesn't that I've never even seen mentioned in relation to machine tools. I'm not saying you're wrong (it sounds like you're more qualified to speak on the topic than I am), but if you're right, then it seems like the whole industry needs a serious paradigm shift.
Should do a Q&A for the build, like what have you guys learned along the way, and what things would you change or have done differently knowing what you know now? Great job 👍
oh... i was hoping to get some more informations about the wiring of the motor. I could use that for my projekt. Maybe some one can help me out? I dont know if i can run this with a power supplie or do i need a battery pack... So much more questions
The love of shiny metal things. You can't help but fall in love with a ground flat surface. Also, I guess everyone noticed that the lathe works fine without the surface grinder. :)
Stunning wideo and great job. I just wondering 2 things. 1- what program you use to move the cnc table. 2- what was that beam you use for calibrate the grinding stone.
That would be great for a cross purpose grinding machine. Make the grinding head easily removable and add a 2"x72" belt sander head. Knife makers are probably the largest group doing these conversions to conventional surface grinders. Accuracy of course suffers a bit but stock removal is dozens of times faster and great surface finishes are achievable. You'd be amazed at the number of people doing this. Check out 2x72 surface grinder conversions, you make like what you find. Done right you could convert it back in forth in 30 minutes or less. Great job on the machine!
Check our Instagram :) long story short: I had to try twice to get a thin enough layer to show anything, but when it did it was very interesting. You can even see the stripes from the stepover/traverse. I think those are only a few tens of millionths deep but I'm guessing fairly unique to our machine
When you ground the magnetic hold down table, it didn't spark. I was told a long time ago that if what you were grinding didn't spark you should not grind it as the grinding wheel will load up and could possibly explode (shatter at speed). Just asking. And you did very fine work on the grinder, thanks for sharing your work.
Just watched whole series, and i probably missed something. What size of rails did you guys used? I am just starting to gather materials to build small surface grinder(manual, not CNC). Your video series is a great inspiration. I am planning to get around 10x5 work area since this is more than enough for my use. I already welded solid frame from thick C beams that will probably be overkill stiffness wise for such small machine, but its always better this way than the other. If you could tell me the size of linear rails you used that would be great, and save me a lot of thinking and calculations. Thanks!
I think you would do a lot better with the chatter with a larger motor. Not just for power but also mass. And even use a flywheel to stop harmonics and smooth out chatter and bogging. Maybe even direct drive but I would think a lot more weight directly on the spindle will keep things more solid and smooth surface finish.
What are you going to do now there's this huge empty "surface grinder build" shaped hole in you lives??? oh yeah...... lathe restoration?????????? I LOVE your closing message..... so true.
That is sweet. "BUTT"' A surface grinder has way more uses than just flat surface grinding. You need the Y and Z axis with a back parallel on the Chuck to grind slides n gibs. Like form dress the wheel with a diamond to side and flat grind.
If it were for my wife she would be hounding me every day to finish the thing. I'd love to see that thing finished, it will be awesome to see the vintage look he's designed into it.
You're going to have to be very gentle with your cuts without flood coolant. That problem with any Grinding is the heat generated locally creates positive feedback. By that, I mean that if you take a reasonable cut, the heat you put into the work causes it to expand towards the wheel, meaning on the next pass you will take a deeper cut and so on. If there's enough mass, and you're gentle, you'll likely get away with it on a Surface Grinder. Don't try it on a Circular Grinder between centres though, it will surely end in tears because the effect is magnified so much more.
wow impressive flat as a very flat thing. Seriously impressive gentlemen. So I guess you'll be surfacing a few items over the next few weeks then :) greetings from down under.
Thanks for making such an inspiring video I really love seeing these things because it empowers me to do bigger things when people tell me it’s not possible.
"Now we can finish the lathe restoration!"
"Is that why we were making this? I sold the lathe to finish this thing!"
"..."
I had completely forgotten about the lathe XD
I for one am anxious to see it used for its intended purpose of grinding the ways on the lathe
@@j7gy8b making this was to learn how to make a surface grinder so they'd know how to make one that was large enough to do the lathe ways
@Anthony Lovell. Yes, that's what I thought - a quick prototype to check, then get some contraption to sort out the lathe. Anyway, it's cool. Maybe they have enough patrons now to send the lathe bed out for a regrind, or buy a lathe with unworn ways.
Within a couple of tenths, on a home-built surface grinder? I'm seriously impressed. Good job, gentlemen, you should be very proud of yourselves.
"do you want to work on the surface grinder?"
"The what?"😂😂😂
Love the ending quote. Great work, guys!
They said you couldn’t do it, but I knew better, great job lads well done,.

Well done lads! You never gave up on it, looks great! 👍🏼👌👍🏼
why didnt you use a 3 phase induction motor instead of the bldc one
A bldc IS a 3 phase induction motor

how do you compensate, for the stone, getting worn?
i was holding my breath when they ran the dial indicator over the job. What better can one ask for!
Thank fucking God. Been waiting for the culmination of this one for far too long.
So how do you account for the material loss on the grinding wheel? On a large object that would change the level of the flatness would it not?
Typically it wares into a taper and you grind advancing in one direction. So as you grind, you start out with the leading edge doing all the grinding. Over many passes it will eventually get to the point where its cutting on the trailing edge, but long before that you should redress the wheel, which will square it back up.

Excellent, most excellent. Now we need some details of the final build. 👍
Can't wait to see what the next project is!!!!
Glad to see you guys got it finished!
awesome finish, guys.
Looks good.. But going by the amount of wobble while it's grinding it could go with some counter weight or getting bolted down lol
whole thing is flimsy should have just cast it all out of epoxy granite

What software you use to control the stepper movement?
Awesome! Now that it's done will you be using it to tube up the lathe bed?
Should do a Q&A for the build, like what have you guys learned along the way, and what things would you change or have done differently knowing what you know now?
Great job 👍
I'm for this, we'll end up doing a follow up so ask away!
Good work guys finally got it done
that last scene was epic even the fail was totally worth it keep up the good work guys
Cool, show us what it can do! Good to see you got the motor taken care of.
