Looking for someone so manufacture a bracket to modify my small trolley jack to enable me to lift my large woodworking bench to enable the access to the power supply and extraction system.
It needs a piece of plate bending/welding and a round stud fixing to adapt my trolley jack.
If anyone can help I would appreciate a call/message.

I assume that the cranked part is going under the bench.
Will the jack not pivot on the front wheels as the weight of the bench presses down ?
Cheers, Andy

Hi Andy,
No, the way it works is the "spade" shape goes under the edge of the bench, then I pump up the jack which lifts the side of the woodworking bench clear of the floor and after inserting support blocks I can then carry out any maintenance on the air or power supplies as they come up though the floor.
I had this system some years ago, but a kind friend borrowed the attachment and he has since left the country.
(I am assuming he took the jack adapter as well)

Ah, okay Alan, I did not realise it's tried and tested in a previous incarnation.
Hope you find a willing candidate.
Cheers, Andy

If you could forego the ski slope part, and have it as a cliff edge (vertical), it could be made from two pieces of 100 x 100 angle iron bolted back to back. That would eliminate the need either for welding or for cold bending or for hot bending.

The diameter of the cylindrical piece that goes into the jack head is not given. That could be bolted to the angle, again meaning no welding is needed. Providing the cylindrical piece is a commonly available diameter, the whole item could be made with a hacksaw and drill.

Simplifying it thus means the skills and facilities required for its making are reduced, increasing the number of potential people who could make it.

A toe jack is available from Vevor for £44.64 delivered to your door (£47 less 5% with VVGG5 discount code) as of today. That would provide an upper cost limit for the item.

Try One Off engineering, just north of Sheffield S73 0TF. They are at brampton

My suggestion would be ask whoever services your car (presuming you have one) if they don’t weld themselves they usually know someone who does.

Hi,
The "Ski Slope" section is necessary to clear the front wheels of the jack.
I previously had this adaption but sadly a "Friend" borrowed it then swiftly moved abroad.

The "Ski Slope" section is necessary to clear the front wheels of the jack.

Your own sketch/drawing exaggerates the amount of slope required.

Lower the jack to its minimum height and measure from the centre of the jacking pivot to the frontmost point of the wheels. Then correct the proportions of the sketch so it matches what you have rather than an artist's impression.

You do not necessarily need a facsimile of the part that has been borrowed, just something that will function in the same way. Look at the problem with fresh eyes and consider what could work. That way your manufacturing resource will be increased.

Would something like this - there are many variations out there do the job?

Or a length of 2x4 as a lever on a brick - when lifted the bench legs could sit on wooden blocks or more bricks and lift each corner at a time (which you would do with your device anyway)

 

[johnnyb]

There's a guy works next to me whose great at this stuff. You'd need a decent drawing and he could price it up. Pay most up front and I could ship it (or you could puck up)

In normal service a trolley jack carries a vertical load. Providing the load sits vertically within the jacks wheels - no problem - capacity is limited mainly by the hydraulics.

Normally the circular plate on the jack pivots as the height increases and the angles change. If it is somehow rigidly fixed to the lever arm I think the jack will pivot on its two front wheels. If the plate pivots the bracket will lift nothing.

A completely alternative approach (albeit without seeing the workbench) - fix (screw or bolt) right angle brackets to the bench projecting ~50-100mm from the side of the bench. Use a bottle or scissor jack under said bracket.

Should do precisely the same job as your proposed solution. Almost non-invasive as brack can be removed afterwards.

I appreciate what you are saying, but sadly I don't have the space to make that idea work. At present I lift the bench edge with a steel bar (1m) then place blocks under. This allows me to get the jack in place and lift to the height I need to insert axle stands. I work totally alone so have to be very care full and cautious with what I am attempting but appreciate your idea. As I had a a modified jack in the past, I found it easy and less dangerous, sadly a so called "friend" borrowed my adaptor and then left the country!!!!

Sorry this is the best photo I have of the Jack for my combination machine, all it needs is a hole in a solid piece of wood? Fastened to the side of your bench, put the jack/towing bar under, locating into the hole push down on the long handle - not shown, and the bench lifts up.
The jack thing could easily be made from two large wheels and bits of scrap wood.

Hi,
like your idea, but as I am working solo, and my space is limited I find it very difficult to get some levers/bars etc., in place as it is I have to leaver the edge of the bench with a piece of 4 by and then place a piece of timber to hold up the bench while I place the jack in position. I don't have any assistance available 90% of the time so have to "make do and mend" as they say.

Agree with your idea, sadly I don't have the space around certain areas of my bench as the workshop is only 3m x 4m and the bench is 2.2x1.4m
Thanks for the idea though.
