Small workbench from a half log

The thread http://www.bodgers.org.uk/bb/phpBB2/viewtopic.php?f=2&t=2507&start=30 got me thinking, especially the pictures of french workbenches with the vise to the left. I saw Sean Hellmann in some video using something similar and Roostoi from Bavaria owns something like that (http://2.bp.blogspot.com/-c7tFiifRgq8/T93AqHs3bdI/AAAAAAAAAuE/nXndDmQRte8/s1600/Foto.JPG), a half log with a vise attached, portable and useful. Today I had some time to kill while my students were on autopilot, so I drew a sketch.

Hopefully you can imagine, what I mean.

Then I ordered the small czech bench screw from Fine Tools: http://www.fine-tools.com/spindel.htm (at the middle of the page). When I got home, I instantly started working and that's the result so far:

It's a 60x80 mm post. 30x80mm go 60mm deep into the hole.

This part of an old pallet will be the other part of the vise.

I still need to order the holdfasts http://www.amazon.de/Unbekannt-Niederhalter-Ausladung-100-mm/dp/B0034YV2RE/ref=sr_1_7?ie=UTF8&qid=1344277578&sr=8-7 from Dictum. One or two, how many do you recommend for a bench top of 300 x 500 mm? Height is 780 mm. I'm not sure, if I'll add the stiffeners to the legs, it's quite stable already. I'll test without them first and add them later if needed. Altogether it will cost about 50 Euros.

Best!

I'd get 2 holdfasts. You can always find an extra use for one if it should not be needed. You'll have more than one hole in the bench anyway, and there will be times you'll need to hold the work in 2 places.

Get 2! promote the economy!!

That was quick! Yesterday morning I ordered the bench screw from Dieter Schmidt, got the order statement and packaging information in the afternoon by email and today I came home and the postman already deposited the package in my shed. So this is stage 2 of my little project, the workbench with mounted vise.

I look forward to seeing a TURNED bench hook... :?
I thought a bench hook looked like this:

Hmmm probably the 1:1 translation of the german Bankhaken = bench hook is way wrong :shock: ... bench dog is the word, I just found out. :mrgreen:

Added a bearing with spacer holes to the bottom of the vise.

mstibs, I'm very impressed by your ingenuity and speed of implementation. You've managed to combine several of my favorite things: bowlmate, Barn-the-Spoon-style raised cutting block, French Roubo-style workbench. I like the look of it.

However the bench is rather small (although I have seen pictures of small French workbenches) and light (mine is quite heavy now, I just added a shelf under it which has about 60+lbs/30kg of weights on it for ballast + a large hifi speaker cabinet + sharpening stones + ...). What do you plan to use it for?

On the other hand, my bench is/was mainly covered in junk/tools/fasteners/..., for which a table would suffice and proper storage would be better. And most of my work with the vice was probably fairly small until I started using it as a make-shift shave-horse recently. Please let us know how you get on with using it.

Indeed, it's quite light and small. I have a self-built bigger workbench with a mechanics vise and two shelves for tools and stuff below. It sits like a stone on its place in the rather dark workshop (small window but with a nice wood burning stove for the winter). But if I want to work in the sun, the small one is my choice. I just carry it over. The same counts for the (planned for somewhere in future) situation, that I need to put it on my trailer and drive to give a course for kids/pupils/students.

:) Yes, I much prefer to work outside too. Perhaps I should make one. Really need to make a shave horse first - or better yet, a combined shave/bowl horse.

Not sure why webshops like me so much these times but as speedy as Fine-Tools delivered Dictum the holdfasts. Bored holes for them and the bench dogs and made a vise handle today.

I noted, it needs the spreaders/stiffeners (not sure about the name) for the legs. The vise puts a lot of strength on the softwood post.
Best!

The name is ' stretcher '
What diameter are your tenons? I am about to build something similar. It must be smaller than 52 cm by 34 by 22 cm so it can fit in a Tesco crate.
How did you cut your tenons? If you did them with Veritas cutter, you should have a tight fit. If you whittled them with knife or drawknife, you will have a more loose fit.
Because your legs are roundwood i.e. not cleft, they will wobble more. Were the tenons dry? If not, they will have shrunk and gone oval (wie ein Eier ). Oval tenons will definitely wobble.

30 mm diameter, largest Irwin I have right now (will change next week, when my Ebay-win http://www.ebay.de/itm/ws/eBayISAPI.dll?ViewItem&item=170885743700&ssPageName=ADME:L:OC:DE:3160 arrives :-) ). They are cut with the drawknive (no money for Veritas yet ) and enough room to sink in if they dry a bit. Both, the log and the legs, had about the same moisture level. But it's not the two roundwood legs that wobble, it's the front post. Though the joint is/was a square 30x80 mm and 60 mm deep tight fit and the post is as dry as Sahara, the strength from the vise puts so much pressure on it that it wobbles a bit. The stretchers (thx for the name) are mainly for stabilising the post with the vise.

Ah, you'll be needing a dowel-plate then. Mike Abbott currently experiments with one of mine to make furniture on his courses. Will report more when I see him early Sept. I now see it could work to start at say 45 mm whittled tenon from the drawknife and progress down the dowel plate to 44 then 43 then 42 then 40 then 39 then 38 mm. I do not yet know that such large tenons will pass thru dowel plate, but it has to be worth a shot.
Here is my dowel plate at Mike's workshop creating 14 mm tenons over 1 inch length:
