A very aesthetic Look for the control box, my OCD kicked in when I saw ( early on ) 3 button screws and one slotted on the front panel but thankfully you corrected that. Despite what you think, a project to be proud of.

Ha ha ha ! Ian, you are a legend. I noticed it too when reviewing the clip before doing the next one. Had to swap it out straight away 😁 OCD? Surely you mean CDO 😉😉

I'm privileged to have known about this from conception to completion, and it has been really interesting to see how Nel has brought it home, very well done buddy.

Well mate, you've been my wall that ideas are bounced off for over 30 years. Dont mention the helicopter though 😉😉😉

Gday Neil, this turned out great, I really like the magnetic clutch idea, thanks for sharing mate, cheers

Hello Neil, You've done a great job as you've taken it from a thought to an actual working device.... I am very pleased to have been following along with this process... Take care. Paul,,

Hi Neil from Australia, after watching your youtube I was inspired and thought about how you did it and knowing the problems you had I decided to build it useing the complete clutch from a car air conditioner. It works spot on. I will sent some photos if you let me know where to send them. Thanks for your inpiration, Regards Merv

Hi Merv !!! Great to hear it worked out for you 😊 If I had access to a complete AC unit at the time, I would have gone down the same road as you. Really pleased one of my mad ideas has helped someone. You can send photos to my email. Its shown at the beginning of this video, would love to see how you did it. All the very best Neil

Very clever stuff Neil 👏

All that shines isn't gold 😉 It looks the part Andrew and will do the job but I think it will need replacing. Due to wrong settings I don't think the threaded holes will hold up for long. But,,,, it works that's the important thing. Thanks for watching and commenting Andrew, it's appreciated. Cheers Neil

That looks fantastic! Nice work.

Very interesting project- well executed! On my second iteration of building one, I avoided needing a clutch by using a stepper motor- I arranged the controller so that it only enabled power to the motor when it was driving- without energization the motor does not increase the effort of turning the handwheel. In use, you never need to worry about engaging drive... There is a video on my channel if you are interested.

Hi Mike, I'll take a look at that video. I read something, somewhere about backfeed from the motor causing issues if you drive it. You had any problems with this? Be interested to know for a future project. The idea turned out ok and was different but not totally ideal. Got issues with it due to lack of consideration from myself. Basically, heat! Got a fix on the go and will reveal my errors soon. Thanks for the comment, always appreciated. Neil...

@@NellsMechanicalManCave If I turn the handwheel quickly without power to the drive, the display starts flickering! But it has caused no problems, and it has had quite a bit of use.

Great job Neil, lovely bit of work on the enclosure. Best wishes, Dean.

That's easily done Dan on the motor end and a good idea. Could hide the chock block inside the E stop enclosure. Only need a NC contact under the stop button. Nice!!!

It turned out great Neil. The motor should be ok. The one i did has never let me down. Even when using the 6 insert 60mm facemill. I think the only difference was i used the high speed of the motor for rapid return. But it's not that much faster. Great video. Regards. Steve.

Cheers Steve, I'm still not overly confident with the clutch yet. I'll get the vice back on and start some trials tomorrow. Cheers Neil

Niel great job. Well thought out and very clean looking. Since you have the belt drive 1:1, why not hook up the motor direct.

Hi Patrick, sorry for the delay in responding. To answer your question, I wasnt sure when I first started the project how much torque and speed I would need, so i went 1:1 as a bench mark. I now know that 30rpm (90mm/min) on the machine is a nice cutting speed in general and has sufficient torque. I am looking at fitting a pair of spur gears which might be 3D printed in the near future and do away with the belt. Just need to wait until I'm back on my feet and build up a tolerance to the new meds, then I'll be hard at it !! Thanks for the question and coming by. All the best Neil

Yeh totally understand. I do a lot of projects that I update after completion. Still great work.

It's looking good. So you want the direction switch to switch the magnet relay off when in neutral? Is that correct? And is it necessary@ Also what voltage are you driving the internals at and what is the voltage and current your relays drive? (I got a box of 5,000 5v coil, 10 amp SPST relays that can do 240 AC or 28V DC from a scrapyard new). I can't help but think an arduino controlling the relays would simplify things though you could also use a few transistors or a logic gate.

Everything is 12v Ben. Probably not necessarily but motor and magnet operating simultaneously was my original idea. I'm thinking of two micro relays as I'm not into Arduino, but the jury is still out 😁😁😁😁

@@NellsMechanicalManCave If you are going to do it with relays you could take a wire off each side of the switch, through a diode then through a relay coil to drive the magnet. You could use either end of the switch to drive the same relay.

@@BensWorkshop that's what I was thinking but was worried if a diode failed it would allow a back feed energizing the second relay in the PWM resulting in a dead short. I'm not sure of the characteristic of diode failure and dont know if they just stop working as in no current flow or flow both ways

@@NellsMechanicalManCave I don't know enough about the way the PWM unit is wired but diodes can fail both open and closed circuit though much more often open.
