- This is part 3 of my buildseries where i am going to show you how i made myself a Milling Machine. This part is focused on the belt drive and the rolling cart.

The build is coming along nicely, ingenious build Thank you for sharing.roll on part four .
Thank you for the nice comment!
I am a bit tied up right now but next week i will start to make part 4.
This thing looks beautiful every step of the way my friend.
Thank you :)
Great series! Looking forward to part 4.
Thank you!
Part 4 is already in the making
Coming along very nicely.
Thank you! :)
Clever build. Nice.
Thank you Matt!
good job
Thank you very much
Looking good mate!
I think that your spindle speed might still be too high, that is if I read your speed chart correctly!
If it is still too fast, you could possibly look for an in-line gearbox unit to lower the output speed of the motor.

It depends.
My collet chuck limits me to a max. diameter of 20mm endmills. This should be within the limits. With smaller endmills the speeds should be high.
However with facemills you could be right.
Thank you for the input and if the speeds are realy to high your idea might be worth looking into.
Further testing will show.
Would you share the 3D models for printing ?
I guess i can
I will let you know when they are online
Is it rigid enough to do face milling on steel?
Sadly i don't have a facemill to test but as it is now probably not. Mostly due to the locking mechanism of the mills arm.
Taking deeper cuts with 16mm endmills is a bit of a challange now.
However i am working on an upgrade for that and i might get a facemill once the upgrade is finished.
The rest of the build should be rigid enough.

why you spend a lot of time to make pullys etc insted buy biger motor and vfd? set of 2.2kw motor and good chinese vfd is under 200euro.
I thaught about that and it is a good idea.
But the motor i got now cost me nothing.
At the beginning i wasn't sure if this project would even work. That's why i wanted to keep my expenses as low as possible.
As a bonus it's a nice example of repurposing old equipment.
I made the pulleys myself just for fun (and to get the right spindle speeds). I just love tinkering and i haven't really seen 3d printed pulleys in that size.
One thing that also kept me from buying a motor and vfd is that i was worried that at lower speeds i might get less torque than needed.
But i am no expert in electronics so i don't know if that would be the case.
Thank you for the comment!
@@wastelandworkshop3839 3phase industrial motor have constanst torque, you can run from 25hz to 100-150hz without external fan. Under 25hz you need use external fan because internal fan was designed to run above 25hz. Under 25hz air flow is to small.
in the past I had a similar philosophy - to do everything myself, but almost a year ago I started a business and now I have to have everything calculated. From my point of view, printing pulleys is not economically viable because my time is also an expense. Time is the most expensive resource what we have
This would have been a great solution too.
However there will be a motor upgrade. But still a single phase 1.5 kW one. I found a good deal on one that even has nearly the same rpm.
That means i don't have to rework my drivetrain system.
I totaly get that you value your time fairly high.
If i would own a business i also would value time different. Just because so much of this time needs to be invested into the company.
More important is that you do stuff you enjoy in your remaining time.
For me that is the homeshop environment.
I can do what i like and can have a little peace without any distraction.
@@wastelandworkshop3839 i think your 1phase motor can run 3 phases - in most cases "1phase motor" is 3 phases motor with one or two capacitor. Most of 1,5kw motors can run on 230 and 400v - there is two setting Y and Triangle.
Indeet it can.
But i am going to leave it hooked up for 230V mainly because i only have one 400V outlet in the workshop and at least for now 230V is more convenient for me.
