Gday Neil, the more I see this the more I’m liking it, great job, Cheers

Cheers Matty. Did a load test too. Run it up and pushed against the bed. 120kgs (260lb) verses the mill at 500kgs. The table slowed a little but I did have the machine off the floor by that time. No wonder my back is f#*ked 🤣

Nice one Neil! He's only gone and done it! Works a treat. Best wishes, Dean.

Yes I did it. Made something more funky than a dog clutch but probably less reliable 😂😂😂🤣 But,,, its opened peoples minds and shown theres a different path. Been good fun though👍

Brilliant 🤓

Excellent!

Hi Neil I knew you 'd gaffer it, great job, now for the easy bit tidying things up, when i'm at a loose end🤣🤣🤣 i may have a go at that, thanks for sharing take care of that back Kev

Hi Kev, hope you are feeling better. I'm still not overly confident but anyone from my engineering past will tell you that. I sat for 2 weeks once on and off watching the computer updates on a bucket elevator I designed. It could lift and transport 700 tonnes an hour vertically and the drive assembly was based on a pizza cutter! My boss thought I saw the design when I visited factories jn Europe but I only approved the chain design there. The drive came to me when I was pished in a takeaway the night I got home 🤣🤣🤣

@@NellsMechanicalManCave Great story, and yes i'm much better, but the little bugger knocked me sidewards, glad i got myself full of anti bodies before it got me😰 see you next time Kev

A very neat solution in the end

Thanks Ian. Still a bit to do to finish this folly 😊

Well done! Great work and must be satisfying to see it running!

Cheers Ben, it is nice to see it working. I'm not finished yet though. Still got lots to do and lots to confirm before I'm happy. Cheers Neil

Thank you for your kind comment! A simple idea that I hope will benefit many . Kind regards Neil 😊

Hi Neil, That seems to work a treat... do you think the resistance generate by cutting something will have an impact on it? I know I keep saying this but it is a fabulous project. Take care. Paul,,

Good point Paul. The mill is 500kgs and I'm 120kgs. I got my shoulder against the table with the feed running and braced. The motor slowed down as the mill started to lift off the floor. Now you know why my back is in such a state. I'm an ex-pit pony 😉 Cheers Neil

great stuff Neil, do you know what model compressor or vehicle it's for and maybe a link to buy the electro magnet.. cheers Jim

Hi jim. It was the cheapest one on ebay. £22.00. Think it's a Vauxhall astra from memory. They all work the same as far as I can tell. 12v I used which when checked was 4ohm so 3amp current draw. If you go for it Jim and hit problems, give me a shout. Oh, brown is - black is + 😁

Awesome project! Do you expect any problems regarding metal chips that collect around the magnetic clutch? If so, do you plan to cover the drive?

Hi Jonas! I am expecting chips to be attracted to the area and planning a guard. Probably aluminium but I might 3D print one, not sure yet. The metal casing of the coil itself doesn't become magnetised but I will cover everything. Really glad you are enjoying what I'm trying to do, it's been real headword on times 😊 Thanks for commenting cheers Neil...

@@NellsMechanicalManCave Thank you for the answer. Of course i enjoy your work! I was trying to come up with a simple clutch for my own milling machine, but the mechanical solutions i found were way to complicated. Your design is very clean and does not take up much space. I am looking forward to the next video, maybe we will see some cutting and how the chips behave around the magnetic field.

@@jonasasche3169 new one uploaded but no chips yet 😕 The clutch does work but don't jump on the band wagon yet! I'm not that confident in my design at the moment. I might have to go down a different path but still use the magnet 🧲 Hold on a bit longer and let me get it working as I want. Cheers Neil 👍🏻

@@NellsMechanicalManCave Sure thing! I might order a magnet in the meantime ;) The custom wiring box looks good, maybe 3D printing isn't useless after all! For the wiring you might want to look into 'relays with latch circuit' (?), in Germany we call it 'self-holding-relay'. You could add button switches into the latch circuit that are activated by the end position of the table, turning of the motor and the clutch. But you probably know about this already.

@@jonasasche3169 yes I am aware of these relays and contractors. Usually an auxiliary NO contractor to hold the coil energised and a NC to break the circuit when activated😉 The odd thing is I learned this in Germany. I used to work with Polysius Krupp (Beckum) and developed several systems, mostly in automated welding and automation. That was a long time ago though. Still miss Germany but I dont think they miss my humour 😊
