I have an area in the old barn that is unused and I wanted to convert to a 'rough' working place. The floor is unlevelled , which require adjustable feet to adjust for the height difference up to 30 mm. The angle of the wall corners are not perpendicular, they are more like 86 to 93 degrees, which require a remissive design.


This is an extreme heavy duty work bench that can be used for really large weights. A bench that I built some years ago according to the same concept, was acting as a stand for a metal bench mill and lathe of approx. 200 kg totally, without any problems.

My build is 4.8 m long and 2.0 m wide at the sides. The work area is 800 mm deep (from front to rear) and 850 mm high from the ground.


The first thing you must ask yourself is:

  • Should there be any heavy, permanently mounted machines at the bench? And where should they be?
  • Will you have any vice (or several vices) mounted at the bench? And where should they be located?

The reason for you to ask these questions now, is that you should locate the cross sections directly below the loads to give the bench a firm support.

Some general tips according vices:

If you work with long objects, consider mounting two vices in line with each other. Obviously more expensive but definitely worth it!. Or if you build a shorter bench with a 90 deg. sideboard you can also use two vices, if they are rotatable

Calculate the number of cross sections needed. I recommend distance of approx. 1.0 m between each section. The bench may be unstable and not sturdy enough if a distance larger than 1.2 m is used.

As a general rule I never place any wood material in direct contact to concrete because moisture can/will be transported through the concrete and into the wood. So a gap, or a large washer, between wood and concrete is advisable.

Also consider any electrical wiring to power outlets, if needed. It's a good idea to have figured this out before building the bench.

What you need:

  • Ordinary wood working tools.
  • General wood screws, countersunk (I.e. diam: 5 and length 55).
  • Angle brackets, 50x50x35x3.0 - 4 per cross section.
  • Angle brackets ,90x35x35x3.0 - 1 per cross section.
  • Large screws, nuts and washers for adjustable feet: Hex bolt head M20x80 or longer. 2 per cross section
  • A lot of wood for building.
  • Laminate floor as protection surface
  • Vices: Optional

Total cost for 4.8 m x 2.0 m (in Swedish Krona, SEK):

  • Bench plate wood: 1060 SEK
  • Wood for cross section, lower shelf and additional pieces: 520 SEK
  • Laminate floor: 336 SEK
  • Angle Brackets 50x50: 72 SEK
  • Angle Brackets 50x90: 48 SEK
  • Hex bolts, nuts M20 and washers: 250 SEK
  • Wood screws, fasteners, etc.: 200 SEK

Total cost in USD: 2486 SEK => 380 USD (Feb 2014: USDSEK = 6.55)

Step 1: Lining Up


First of course, fix the walls if they are damaged.

Lining up:

Start by drawing a horizontal levelled line at the walls describing the final working upper surface. (I am quite tall and prefer a working surface height of 850 mm). Be VERY careful that the line is absolutely horizontal because the whole build will rely on this line. Use a long level or a line laser. Double check the line position.

Find out where the cross sections will be located and at what height. The height is calculated by subtracting the total bench plate thickness together with the upper cross section height, from 850. In my case: 170 mm below upper surface.

Fasten consoles:

Firmly fasten the larger consoles 90x35x35x3.0 at the walls (with plugs if it's concrete). The purpose of these are to give you a small gap between the wood and the concrete wall, and secure the bench to the walls. It's very frustrating if the whole bench moves around or rattles when you are working furiously with some mean parts that need persuasion...

<p>Beautiful piece of work, thanks for sharing.</p>
<p>Thank you so much for sharing your project and designs. </p><p>I've made my own version that condenses the dimensions to fit in one end of my narrow garage / workshop. The whole structure is on the wonk, so the adjustable feet were essential for a level work surface, and they work really well. </p><p>Again, a big thank you from the UK for sharing.</p>
<p>Nice to see! Thanks you for photos!</p>
<p>I used your design and drawings to make this, and I am so happy with the result! Just moved into a new house, and I&acute;ve always wanted a nice work bench in my garage. Just made some adjustments due to different material sizes here in Norway. Thanx for the inspiration!</p>
<p>Very well done!</p><p>Och lite &ouml;l hj&auml;lpte, ser jag ;)</p>
<p>My man cave is almost done. Og &oslash;l hjelper alltid:-)</p>
<p>I used your design and downscaled it a bit to make my workbench :-)</p>
<p>Nice! I really like it!</p><p><em>(Especially your Drill-Press, I'd love to have one that size!)</em></p>
Will improve this my working corner
Will improve this my working corner
Thanks for the input. Realy nice and functional working area. Will use some tricks on mine existing &quot;man cave&quot; corner. I will add laminated surface and some top shelves. Great!
<p>Nice, but definitely not Extreme Heavy Duty, or just a standard bench.</p><p>An easy upgrade to heavy duty (but not extreme) would be to glue the top pieces together, then attach a 2x6 on the front on edge. </p><p>Calculating sag tells me your bench as is will sag about .1inch with a 2000lb load. Adding the 2x6 would half the sag (double the stiffness).</p><p>Without gluing the top boards, a 2000lb weight would probably damage the top.</p>
<p>What is oil hardened board ?</p>
<p>I think it also might be called 'hardboard'.</p><p>It is usually available in different hardness. Select one that has as hard surface as possible.</p>
<p>Tempered Hardboard is what he is talking about.</p>
<p>Oil hardened board is wood that has been boiled in Olive oil or Linseed oil for 8 minutes. It's good for carvings you want to last a long time as well as wooden pulleys. It also helps keep wood from splitting.</p><p><a href="http://www.woodcarvingillustrated.com/forum/f38/hardening-olive-oil-35850/" rel="nofollow">http://www.woodcarvingillustrated.com/forum/f38/ha...</a></p>
<p>Great looking work area. I have an almost identical layout that I need to build out for my wife for her own work area. Now I have no excuse to put it off except maybe converting it to the silly US system of inches/feet, etc. (Not a real problem but I may play that card if I need a few more weeks before I get started) I think I'll rebuild my own area after I get hers done, mine was supposed to be a temporary setup anyway. Again, Great Job and great Instructable, thanks for sharing it.</p>
<p>Sorry, can't resist ;) You know that there is just three countries that havn't converted to the metric system yet? Burma, Liberia and... well, ehum... USA.</p><p>Good luck with the build!</p>
<p>The United States being one of only three Countries: :=) While it is true we don't use the metric system, a few of us are trying to convert. It ain't easy for this 64 year old to go from something I have used all my life to a &quot;new/Old&quot; system. However, coming with the global economy we are seeing more and more of it. I would like to see the US switch in the schools, but it would take a generation before we saw results.</p><p>As to the bench, it is a great idea and a good use for the space. I have a similar area that needs or is crying for this type of bench in the basement. </p><p>Thanks fro your work and shareing. </p>
<p>How can you say it is an &quot;Extreme Heavy Duty Work Bench&quot;? For my standard work bench it would have to take 600 lb at any point. A HD bench would have to take about 1000 lb at any point. An &quot;Extreme Heavy Duty Work Bench&quot; would do double that. I doubt this bench could do that work day in day out. Why use such language? Just say it is a useful workbench, which it is, but it's not heavy duty or &quot;Extreme Heavy Duty&quot;</p>
<blockquote><strong>A ledge:</strong><br> Screw a ledge to the wall. Looks nice and makes the bench easier to clean without damaging the wall.<br></blockquote><p>It's also good to keep small parts, screws, etc. from falling into that gap between the wall and the bench top.</p>
<p>That is awesome sized work bench! Ah how I miss having my own home.</p>
nice workbench!
<p>Well done best 1 I've seen so far</p>
<p>I think calling it &quot;super heavy duty&quot; is a bit over generous. First, the lumber is spanning with its weak axis. With a thickness of 45mm, it can safely span no more than 900 mm. I am accustomed to using workbenches with 50 x 100, turned on edge, to take advantage of the strong axis of the wood. The boards are all face glued and span about 1800 mm. THAT&quot;S a super heavy duty workbench.</p><p>Still, your bench looks good and should handle most do-it-yourself kind of work. With the hardboard on top, I would have fastened the edges of the boards together to make the top act as one piece.</p>
Good job! amazing :)
timely! just moved house and about to build a workshop. Took my old bench with me. This gives me several improvements to implement.
<p>This is too funny! In the real world craftsmen use a sacrificial layer of Masonite (hardboard) or plywood as a work surface. Once one side is completely ruined they flip the sheets over to renew the surface. </p>
snyggt o stilrent.
Very nice. Re the saw- is that a hardened tooth saw? If so it may be sharp but it cannot be resharpened. I would say saws that can be sharpened are better. Hardened tooth saws you can only throw away when they become blunt.
<p>Yes it's a hardened saw. I like it because it's a little bit thicker than other saws and that gives a very straight cut. It doesn't bend or wobbles as much as thinner saws may do sometimes. And it's razor sharp.</p><p>I agree with you that an non-hardened saw last longer because it can be resharpenend. Therefore I have both kind of saws, for different kind of jobs.</p>

<p>Excellent job and great workshop, I will trying to perform in Mexico, I have a question, how you hang up the shelves?</p>
<p>The shelves on the wall, are mounted at the top with simple angle brackets screwed to the wall and the wood. At the bottom there is a ledge (thin, long piece of wood) screwed to the wall that bears the weight.</p><p>Or do you mean the shelf at the bottom of the bench?</p>
<p>So much talent and expertise in this build. I already have a workbench but I will certainly update it with all the great stuff from here !</p>
<p>which program did you use for the drawings?</p>
<p>I am using Catia V5. Modelling is done in 3D and projected to 2D.</p>
<p>Muy buen trabajo...felicitaciones. una idea, pintar el muro de color blanco...</p>
<p>Jealous. Like every guy (and probably gal) who sees this.</p><p>Great work.</p><p>Please do more.</p><p>Thank you.</p>
<p>Excellent photos and workmanship. Love the top surface too. An inspiration for my soon to be work shop.</p>
<p>Envy.LOVE! LOVE!</p>
<p>Cool!!!!!!!! Congratulations!</p>
<p>Seriously amazing. I mean really. </p>
<p>Excellent job. I too, like the use of laminate flooring. Very good, and understandable instructable.</p>
<p>Very nice design, well thought out and executed. The laminate flooring is genius.</p><p>I have a few &quot;vices&quot; myself but this is not the place LOL</p>
<p>I am envious. One day it will be my turn to have a place where I can make my workbench. Great job on yours!</p>
<p>Great bench! I really like the finished look, you planned this very well. Thank you for sharing with us! </p>
<p>This is exactly what I need in a work bench!</p>
