Life in America - I made the move.

A very wise builder friend from years back said: "I steal with my eyes"

He looks at something and then makes it himself.
I see Mr Zog making a stoeletjie with bits lying around
and some castors off something left out on the side of the road.

Just remember that the definition of junk is "something that you throw out two weeks before you really need it !"

Apply this pulley configuration on a scissors lift:

http://www.technologystudent.com/gears1/pulley8.htm

The pulley will be attached to the axle of the rollers.
The action of the rollers on the moving legs turns the diagonal force of the load into a horizontal force in resistance to the pulley system.
PS - I think a horizontal pulley would work best for ground clearance.

A belt?  Would you not have to have a tensioner on the belt as the scissors and or table moves vertically?

What about clearance?  The table will be several inches off the ground to clear the pulleys and belt, may run in to a clearance issues?

  Here we go again...!



The winch is mounted horizontally across the fixed end.
The cable runs horizontally to a pulley wheel mounted horizontally on the axle of the scissors wheels.
The cable then returns to a convenient fixture point near the winch.
The tension in the winch cable does all the adjustment necessary.
All clearances can be accommodated in the fixed frame depth as the cable runs parallel to the floor.

I'm not following...could you draft a drawing?

I like the simplistic ideas like this one:

OK let me explain something that few people seem to grasp, answer the blerry question!

The question is not how do I lift a mower 1m into the air, the question is how do I get to work on the underside, to change blades etc. 

Its not a bike lift question. 

love the bultaco

With Zogs participation I accepted he was also interested in the possible table solutions.

Also thought working on the underside of a lawnmower was as simple as tilting a lightweight one or lifting the edge of a heavy one or having a hole or tracks on the table.

Cool, I is an injineer, so was trying to explain the requirement.

OK so I went back to see what he actually requested.

So remember I said that I want to find thrown-away lawnmowers etc. and fix them up and sell them?

Well, I haven't found any yet, but thinking about how I will go about doing the job got me to thinking... 

Lawn mowers can get pretty heavy. And physically lifting them up onto a work table isn't always easy on the back. So I have decided that I need to make a special work table for this job.

I have 3 criteria for this table;
1. It must start off low to the ground, then be able to lift up to a comfortable working height
2. It must have a steel table surface so that leaking oil, grease, and fuel does not destroy a wooden surface
3. It must be strong and durable. And cheap.

So, for the steel table surface. I have noticed that there are two pieces of flat steel sheet at the new shop at work. They were there when we moved in. I will ask the boss if I can claim them. They are pretty rusted, but I can sort that out easy enough.

Then the lifting up. I am thinking that if I use a scissors-type structure and use a threaded rod with nuts, then I can build something that can lift up.

As for the strong and durable, well I will probably just over-engineer it and make sure that it is strong and lasts well. As for the cheap, well I have lots of bits of wood lying about, and can probably get the whole thing made, except for the threaded rod, with what I have here at home.

I have already thought of a few challenges, like for instance how do I bend the edges of the steel sheet over the edge of the wooden frame without a bending machine? And how do I install the threaded rod into the wood so that there is minimal play and maximum effectiveness?

These challenges will all be figured out in due course.

In the meantime here is a very rough and dirty sketch of what I am thinking about 

Advise and comments welcome

Yes but it doesn't mean he is right.

Sorry for the thread hijack Mr Zog - I promise it is my last !

BO, I do not have fancy CAD software available to me as I am retired from my profession.
I am making do with what I have on a normal laptop.
I am showing a concept - if you can't see it, then I suggest you have no 3D conceptualisation skills.
Either you see it, or you don't...

or you are taking the piss out of me and that I do NOT appreciate !

[BOZO]

And not that I’m an ingineer at all. But I was wondering how you were going to get it to your place. I mean if you can pick it up to load it onto the back of your bakkie, then surely you can just carry it to your counter top.

Valid question. 

If I go with the scissor jack idea I will get a 12V winch for $50. Then I will make it easily removeable and find a way to fit it (also easily removeable) to the front of my bakkie's loadbed. Then I can just pull whatever up the loading ramps and onto the bakkie. And release it slowly to get it off again.

Yes I can just lift up a normal mower if I have to 

But some of the bigger suckers can and do get moerofa heavy... 

[Mr Zog]

Thanks for all the ideas guys. 

Definitely given me lots of food for thought 


Fuddy, I think Big Oil is pulling your leg

Okay...I can see it now.....thanks

That took a while - for you guys to catch on that BO was messing with you
