    Default Mill winch

    Just looking for ideas.
    I just acquired a milling machine. One of those mill/drill machines.
    It has a handle on the side of the head to wind it up and down on a gear rack. I am finding it to be a real major effort winding it up because it's so heavy. Even though it's geared quite well, around 5mm per handle rotation, it's still a struggle. To add to this, I can't get it to the top because the handle ends up way over my head and that's ridiculously awkward.
    The force required to wind it up is approx. 8Kg @ 135mm (handle length).

    What I need is a motor gearbox arrangement, like a windscreen wiper (worm drive) but stronger and more powerful. DC would be and advantage too for speed control.

    The rack has 23" of travel at 4 TPI. That's 92 turns of the handle to get it from the bottom to the top. If I could fit something that does that distance in 1 minute or less I'd be happy. Of course I could fit extra gearing if necessary to obtain that power and speed.

    Without spending too much (pensioner you know), what items have a thing like that so I can scavenge one.

    How about a bigger head lever?

    a cordless drill does the job , but i have seen the wheel
    removed and a bipolar motor fitted onto the spline the handle
    was connected to.

    how about you loosen the clamps ???? I have one and if you dont release the clamps it wont move but you can force it by winding the handle some people do up the allen screws too much which also makes them hard to turn it moves easily if done right don

    A longer handle would make it seem lighter but then the turning circle is larger which prob equates back to similar effort required.

    Photo required.
    The head is prob over 100Kg and much larger than it appears in the photo. It's huge.

    yep thats the same as mine , on the other side are the clamps 2 of them then it will swig around and go up and down easily some times the moving rack twists slightly but just push it back level and all ok don

    That it correct !

    but there's nothing I can do about it I'm afraid.
    About 15 years ago the wife and I copped a really bad virus which I remember resulted mostly in a severe sinus infection. She got over it fine but it had a dramatic effect on me. I lost around 1/5th of my body weight in 2 weeks and haven't been able to get it back. I now have zero fat anywhere and I can't find my muscles. All my life I was a lean but strong 58 kilos. At least I can now say my weight is stable at 44Kg. Yep, skin and bone, at my biceps is around 10" circumference and I struggle to lift and carry more than 10Kg. Speaking of bone, I also have osteoporosis, and asthma (which has turned into emphysema). I have to eat gluten free, lactose free, pepper free and onion free because of gut pain. Any attempt at exercising to build muscles only seems to causes injuries because the following pain can be excruciating. And there's more....

    Having said all that, I've learnt to live with it. I just keep busy with movement and light exercise (usually in the shed).
    Spending some of my time making things that make life easier is a priority, and it's a great hobby, to design then build to my requirements.

    In the past 2 weeks I've gained 2 extra pieces of machinery (early Christmas presents). For years now I have wanted a Metalmaster HM-51 milling machine from Hare & Forbes and I pretty much had the misses talked into it (she has the purse now) when suddenly a beaut $5000 4-axis CNC router popped up on Gumtree for a steal and I just had to have it. The sacrifice was this mill/drill machine.

    The shed's lookin' great now.
    I have a 3D printer which will make parts for the mini lathe, medium lathe, milling machine and CNC router.

    This machine is an RF-31. Around 300 Kilos worth.
    Yes, the clamps were fully loosened. The column and rack thoroughly cleaned and oiled.
    It was near impossible to raise it before that.

    I'm envious!!!!

    I have one small bench-mounted metal lathe and a floor standing pedestal drill.

    I enjoy lathe work and make little bits and pieces as I need them.

    My father was a wheel-wright and carpenter and his father and grand-father were smiths, so perhaps I've inherited a little from them, although my main occupation has involved electronics, which I also enjoy.

    nice cnc . I just finished building a 1200 x 900 setup with a working bed
    of 820 x 650. I am in the process of adding a 15W laser to it as well
    just waiting on a new control board to run lightburn.

    Its sad how we collect machines

    i have the cnc - wood lathe - 2 x 3d printers and the list goes on

    You need to throw a dust boot on makes a huge difference with the mess
    and air born wood particles and connected to an old shop vac in a box
    to quieten the noise.

    I made mine with the 3d printer saved me about $140

    Yep, already in the planing. Where it's sitting at the moment is only temporary.
    I have to build it a solid table to sit on, complete with a lift up cover to keep the noise in, and a shelf to mount the vac, controller and computer stuff.

    So getting back to the original subject.
    I thought about one of those chair lift mechs.
    You can often pick one of them up cheap if the chair is dirty or torn. It would certainly be powerful enough but I need a rotary output not linear.

    Sorry I just got a chinese lathe 6/12" 1050 mm bed -four / three and six/jaw chucks m3 morse tapers on etc and insert tips vsd and 1.5hp three phase motor plus the usual thread cutting gear have fitted digital readouts to x y &z works great but i dont have enough work for it but who cares it there when i need it , the mill drill is the same except mine is 3phase then theres the floor drill etc and the linisher which i use the most also have a wet linisher i got as payment for a job the belt is 300 wide and bloody expensive was used for edging snow skis and then the welder have caddy tig and argon setup and mig alloy welder with corgon gas weldwell setup and 12"sawbench for alloy sheets and wood and drop-saw for both too . But my best toy is my lawnmower its a 60" hustler zero turn ride-on with a tow hitch I have made for the front great for moving boats and caravans around sections . It takes 7 minutes to mow the lawns front and back , Its that much fun that I pop over and do the neighbours as well before they can start theirs and wake me up on a sunday morning. hahaha

    Agreed, I used to love the ride on. I was always looked at rather strangely by those unfamiliar with me when they saw me mowing my front lawn with it. I usually did it when I finished mowing the school across the road.

    Loopy, could you just mount a roller/pulley arrangement on top with a counter weight(bricks or a 50kg sack of cement or something) to take off the load for easier travel?

    What I don't like about using a motor is the inaccuracy of lowering the drill to the work piece usually due to the inertia of the motor.

    I only have a small bench press drill probably 30kg but I need it to be down to 1/10mm accurate with some work pieces. There is no way I could work with it using a travel motor unless it was a stepper where I could input the travel distance digitally.

    I don't have a proper lath, just a tiny Chinese toy lathe that I modded with a brushless speed controlled motor and fitted a hardened steel chuck.
    I don't really need it much nor my 3D printer and can't see the use for a CNC either as I don't reproduce things in larger amounts, would take me much longer to input/draw up the software than cut/mill/drill the one-off pieces I need by hand.

    I think I can consider myself a surgeon with the Dremel or if it is a bit larger with the angle grinder

    I am probably twice your weight, just love my food and beer too much.
