Literally the best video on youtube! How has that concept not got more views? it's a brilliant idea. Woodworking is so expensive and it's great to see youtubers create cheap woodworking hacks
This is the best novel woodworking idea I've seen in ages, great concept in the first place and community contribution.
The two tenons, the manfully screwed connecting boards at the back, and the vise comprise a rough parallelogram. The cam pulls on the top tenon and pushes the bottom tenon backwards, forcing them apart so they press against the table top and the floor. Replace the two left-leaning boards at the back with one board angled to the right using dowel pivots, so the cam action pulls the tenons together. Install horizontal rails to prevent them closing and they will clamp onto them and enable the cam to bend the spring/vise. Well, it looks good on paper :)
Isn't it amazing, the power of collaboration? I noticed when you do use the metal bar, it racks the entire end of your workbench. Note to be careful with that. Great work!
Great vise/vice. All you need now is a good auto painter to paint some flames on the jaws!!!
If I'm not mistaken, the angled back braces (that keep the main tenon-bar and the floor bar parallel) shift as you clamp, 'locking' the two bars in place via friction with the floor and the upper table stretcher... but the downside to this is that it also lifts the table up slightly (as can be seen by the slight shadow-gap under the rear table leg @7:06, and by the ease with which the table gets pushed back in the intro when applying the cam-lever, plus around @7:40, when the pressure is released and the table drops slightly)
The same mechanism, but with the 'floor bar' running just above the bottom stretcher would probably give more clamping force, because there would be less vertical movement (the top and bottom stretchers cannot be as easily separated as the top stretcher and the floor)... but this would require cutting yet another hole in your table leg :D
You are right I does lift the bench at times. It would be better to have the bottom tenon over the stretcher, however the stretcher is bit high for it to work. I'm retro fitting this to my bench which is an issue. If I was to build a bench with the vice in mind it would easier. I would keep the stretcher on the floor.
I have been watching you leg vise series and I believe you are really on to something. Good work!
Thanks 👍
man you really outdone yourself john, this vise is amazing! would love to see your mind have a crack at a bench vise idea. for those of us that do not have the space for such a grand workbench that can fit a leg vise
I have a plan for one I'll start work on it.
John, I watched step 1 and now your "final version" glad you were open to taking suggestions from your viewers...you did a great job.....that's a serious workbench you have there!
Fantastic work, John! 😃
It should be done this way for centuries! But it took you to think about it! 😃
Stay safe there with your family! 🖖😊
No Cork in Ireland? My geography teachers lied to me!
something you could also do is add a second cam lock to the bottom of the vice. with it facing into the floor. this will hold the front face in place. could eliminate the need for a bar to go through one of the holes.
Absolutely awesome improvements! Thanks for sharing! I'm viewing in Warrenton, Virginia ~ USA
Very great, well done John
Cheers
I have been searching the internet for for a homemade leg vice , and I Love the Idea of a camlock vice ...Thanks and great job.
Glad it was useful
Very nicely done John 😁👍. To see the design evolve as a direct result of viewers feedback is refreshing and the fact that you absorbed the ideas clearly shows your intentions for this project is for the benefit of all us viewers. So a big thanks from all of us 😁. Now go and get that beer, you deserve it 😁👍.
I've been actively looking for a video like this for a long time! I'm happy you went and made it!
Hey see if you can put either some timber in a cross pattern over the legs or a solid sheet of ply over the end in such a way its not gonna effect the vices operation should prevent a lot of the racking we are seeing. Nice work 😉👍
That is an amazing build! Well done sir!
Great workbench and unique shape of legs 👍👍
A simply phantastic idea, congratulations! (Innovation is not seen often on this platform.) Thanks for this inspiration. Greetings from Switzerland!
Glad you liked it, hello from Ireland
Really nicely done! Need to make one of these myself now
Well done, John. Love the old world look an all wood mechanism has.
Great job John. Super improvements. How can it possibly get any better!!
Good job John
hahaha I saw the bench untwist and it blew my mind lol, that put the amount of force into perspective for me, this build keeps getting better and better! can't wait to see what else you come up with!
These are GENIUS!!! I almost can't believe that these didn't exist before! I'll have to consider this for my nailed-together nicholson that I'm thinking of making!
That being said: why not have the handle go upwards instead of down? The lever will have to be shorter, so it'll have less leverage and will take a bit more elbow grease, but I imagine it would be better for the back. Less bending down, and you can put your weight on it to open and close it. I'll have to do my own experiments...
EDIT: other idea: Some kind of foot hook/pedal to make it possible to quick release/clamp it by foot. The lever could be even longer and reach to the floor, in that case. A possible trip hazard, but the thought of being able to kick a vise open AND closed appeals to me... What if the cam didn't have to spin perpendicular to the ground, but instead parallel, like an end cam? Then it could even have a sliding vise screw lever! So much potential! I need to do some small scale tests, I think.
Glad you liked it
Great idea to copy the f Clamp the only small change I would make is to turn the two diagonal pieces around. Because when you clamp it is causing the timber to go into tension
Instead, it should be in compression, in the long run, to have less stress on the screws and timber.
But if you are only looking to clamp small pieces I don't think should really affect it.
This is brilliant stuff! Fun project!
John, Have a look at this, not so much the build but the ratchet locking mechanism at the 2.20 minute mark, maybe an idea to stop the slipping
Great video John nice work
I've been thinking of something similar for some time now.
I never understood why not have the fulcrum where the screw/wedge/cam is usually located, then have a cam or wedge on the bottom. This would give much more power, with much less effort. Simple physics.
In my head I picture the cam lever on the bottom, but working toward the back, under the end of the bench and out of the way of tripping over it. Just reversing the locations of your pin board and cam, but cam is pushed toward back of bench and works backward from what you have, eg.. up is lose and down/perpendicular to chop is tight.
Just haven't worked out how to make it convenient to use yet. I guess some lever/arm extension arrangement to put the human interface in a better location than under the bench.
I'm currently building a bench based on Rex Kruger's Joiner Bench, and plan to attempt this.
Would be great to see a drawing of this idea.
My own thought is, you have now built in a racking motion into the vice. The force at the top of the vice jaws is far greater than at the bottom of the jaws, this on certain lengths will cause problems. I hope I am wrong, but it it is what I can see.
Hi John - loving your ingenuity with this design - thank you for sharing with the community. I would suggest adding a foot operated cam to bind the lower arm of the vise instead of the offset holes. Sent you an email with schematic. Hope it will help.
Liked and subscribed!
Nice work....its been good watching this thought and build progression mate...l've been assimilated l think....
Glad you enjoyed it
This is dope. Did he ever make plans?
Might be an ignorant question, but could you touch on the advantages of leg vices vs end vices vs moxen etc. I haven’t really heard/understood the pros and cons of different vices.
Thanks!
Yeeeeeeeeeessss you used my idea, gonna drink a Guinness now 🍻👍😉
Nice work...smart.
Thanks 👍
Oh by the way I'm building one, I'm not in the same position as you with a full sized shed, in fact I only have a garage that I share with 2 cars so I have a corner of the in house garage so I have to be a bit different with what I do but the eventual vice will operate in a similar manner, so it's thanks to you and UA-cam popping your vids up in my feed, I wouldn't be doing this🍻👍
Good stuff glad it was useful
I rather prefer the ratchet or engaged tooth version. But the floor wedges are a bit inconvenient.
Perhaps you can make a bottom rail which has teeth that engage in the opposite direction. When you lift the vise leg to disengage the upper teeth it could simultaneously disengage the lower teeth. Then when the leg was adjusted to the needed length dropping the leg would lever the upper bar to engage the upper teeth while dropping the lower bar to engage the opposing teeth. This would probably require a careful design of the dimensions, but should give really strong clamping.
Just a notion.
You could do that but i'm trying to keep it a simple as possible and retro fit my existing bench which is not ideal.
Have you considered building it like a cam-clamp? You wouldn't need the top bar.
Hive mind? Wait, are we the BORG? 😱
You seem to have a little resistance when pulling it out. Would waxing those moving parts be a good option?
i still don't understand how the new system works. How did you determine the angle of that diagonal piece?
I would probably put a cross bar on the end of your handle so you could use your foot to lock it down and hold your workpiece with your hands.
Great improvement there Greg
Hi John, a mightily impressive leg vise and extremely well explained. I have a question, would this set up work without the stretcher being so close to the top bar or is that a requirement? I’m building my bench at the moment and if the stretcher is required I can add it before I continue. Cracking series and thought process.
It helps keep things stable, the weight of the leg vise is pushing down on the tenon arm so the stretcher keeps it level as it moves in and out. It might still work fixing both tenon arms together but I would put in the stretcher.
Thank you John, I’ll sort the extra stretcher and make this awesome vise.
@@ianvoden8915 Hi Ian, would you mind show us your version? Thanks a lot.
Umm the opposite leg lifts of the ground
