Hello everybody:

This is my first attempt at making an instructable (I had to make one some day)

I live still with my parents and have not neither the space nor the money to set up my workshop, so I have to be creative to make something.

An essential tool in any workshop is the vice, used to grip stuff, crush stuff, push stuff into some other... I knew I needed one, but could not afford paying for a new or used one. Then, one day I found a car jack, and thought I could turn it into something useful.

Excuse me if I make any writing/spelling mistake, English is not my native language, and excuse me for the photographs as well, art is not my specialty :)

Step 1: Planning

Before getting my hands dirty, a good planning/design is essential for everything.

I thought of many designs, but I finally chose a woodworkers vice, mainly because I thought of it as more feasible with what I had.

I would use the whole screw and nut from the car jack, (around 40 cm long) and, for the jaws, reuse the metal.

Step 2: Materials

The jaws (wood) measure 35 cm, and are 3cm thick and 9 cm high (From a pallet board)

The angle iron (1m 25mm) was cut to 32 (two pieces, reinforcement for the jaws) and 36 (end piece)

The guides (1m 8mm steel tube) were cut to 45 cm, producing 10 cm of scrap.

The handle was made with a 6mm metal rod. Improvement is in progress, ideas are welcome.

x4 8mm bolts, many washers, and 4 wood screws.

x6 4mm bolts

I also needed a 8mm and 12 mm wood drill bit, 8mm and 4mm metal drill bit.

Tools: power drill (also from the trash), hacksaw, screwdriver, bastard file

Total cost in materials: around 15€

Step 3: Cutting and Drilling

Cutting:(the easy but boring part) First, disassembling the jack (four cuts near the joints)

Then, cutting the pallet board.

Cut the angle iron and the tube (a vice would have been very helpful)

Drilling: Due to lack of tools and experience, I had to file A LOT for the screw and guides to fit and slide properly.

Measure and plan carefully where are you going to put the guides, because, at least with this design, may things could go wrong. A drill press would have helped a lot here, as well, to drill everything at once so holes match.

There are 3 holes in each jaw (wood) (12 mm for the spindle and x2 8mm for the guides), 4 holes in each angle iron (those that screw to the wood and those for attachment to the car jack), and in the end, for screwing to the bench (not yet) and for the guides (it serves as stopper).

The guides are drilled as well (I first glued the washers to the tube with cold weld, but it did not work well, so I decided to use bolts as stoppers. Was a real challenge to drill 8mm.

Filing: the longest part was to file a groove in the wood to make the "joint" of the car jack fit better and make a straight line.

I think the photos explain themselves better than me. Sorry for the quality

Step 4: Handle

I made the handle with a 6mm rod, cold bent to fit in place. I know it looks crude, but it is fully functional.

I believe the jack was abandoned because it lacked the handle, and I was too lazy to search for spares.

Step 5: Does It Work?

Of course it does. A whole new world opens before me.

I realise I have made (I knew there were going to be) a number of mistakes; maybe someone else can spot even more , so feedback is appreciated.

Thank you very much if you are reading this.

And comment!

the same idea can be made without disassembeling the jack ,by removing the center rod and fixing then jack in its place ,it gets a little too bulky but this way you get to keep the jack .
Hi!<br>I am sorry but I cannot understand how you would make it:<br>Where would the jaws go? <br>How do you compensate for the jack structure angling? do you have a pic?<br><br>Thanks!
<p>Nice project. I really like reusing, re-purposing, old equipment. And it looks like you have a beautiful wooden floor. I envy you. </p>
<p>Strange, jacks were run out of store.....kidding, nice 'ible! </p>
<p>Over the years I've had to explain to a lot of people why, buying a chunk of all-thread big enough to make a vise was probably not a good idea. Now I have a place to send them for a much better idea.</p>
<p>Nice instructable! A great idea to re-purpose those dangerous scissor jacks. I will have to find my old jack and try this!</p>
<p>Add some holes to the top of the jaws and you can create a variety of holding devices for round or odd shaped stock:</p><p><a href="http://images.meredith.com/wood/images/2008/03/p_benchvise.jpg">http://images.meredith.com/wood/images/2008/03/p_b...</a></p><p>Google &quot;vise dogs&quot; for plenty of other simple ideas:</p><p><a href="https://www.google.com/search?q=vise+dogs&num=20&newwindow=1&safe=off&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjMs9aS89rJAhWKSSYKHWTJA5kQ_AUICCgC&biw=1480&bih=925#imgrc=_">https://www.google.com/search?q=vise+dogs&amp;num=20&amp;n...</a></p><p>Nice work too, BTW.<br></p>
<p>Thanks for the idea! </p><p>I also thought on making them at this time, but I believe I will wait until I need them.</p><p>I am a bit worried about shear stresses; maybe it can be overcome with thicker dowels. What do you think?</p>
You are correct, wait until you need them, if ever. I use dowels from 3/4&quot; [19mm] to 1&quot;[25.4mm] diameter, or simply what I have on hand.
<p>good one !</p>
<p>Thanks!</p>
<p>Woah, cool project! But is the pressure even? I would need this device to clamp wood together to make cutting boards.</p>
<p>Hi!<br>Althought it might look uneven, the mobile jaw adapts to the piece you are working on as it is tightened.</p>
<p>Wow. That would make a really powerful clamp.</p>
<p>I have yet to explore its limits :)</p>
