- Whats Happening Everyone! This is day 2 working on the camlock leg vice, I have added a new mechanism so it now has a wider clamping range. Its now a working prototype woodworking leg vise/ vice.

That's fantastic John such a great simple concept! I must say your work rate is impressive too, from suggestions last night to incorporated mechanism plus an edited and uploaded video 24hrs later. Hats off to you!
i feel privileged to have been a witness to the revealing of what should be the "McGrath Vice/Vise", a most excellent workshop tool. Well done, Man in Shed!!
Cheers man
Excellent idea with the saw tooth's
Well done John 😁. A working design, a working prototype, a modified prototype, a fully functional tool and two videos filmed and edited in two days.... god.. you must sleep less than I do 😂. Great job, keep it up 👍. You deserve a beer 🍺. 😁👍
INGENIOUS.
Excellent video and process.
Thank you so much for sharing.
No problem
I think jay bates put a taper on the inside bottom of the chop that motors the floor wedge to help prevent racking ...
Great effort make and works a treat. I'm tempted to have a go at making your bench so l can install one. As you say 8 inches is enough for everyone...😲
more than a handful is a waste they say
Brilliant, John. You are rapidly becoming one of the go-to sources of wisdom on UA-cam. Brilliant idea. One thought I had was to replace the tenon with a wooden screw that could screw into the leg by rotating the cam-lock. Like the device that holds the bicycle saddle. But that would not be as quick to adapt to the various sizes of wood as your saw-tooth mechanism. The wedge at the foot is brilliant and I'm going to add that to my existing leg vice. If this CoVID lockdown ever ends we'll have to wait longer for your flashes of creative genius. Have another beer. G'luck.
Clever idea. I fancy trying out the build,
Go for it
Use a cam lock on the tennon to actuate a clamping pressure on the tennon much like the brake on a car. Make a couple of "plates" with material that has a high coeficent of fricton that will grab the tennon and keep it stationary. This would replace the gear rack or locking pin.
Have been subscriber nd follower of the top woodworking channels for a number of years now. THIS must be the best I ve ever seen!!!! Brilliant John and to all those who pitched in and gave advice!!
Wow, thank you!
You also mentioned your design brief in vid 1! Taught my students for many years that a proper design brief is the battle halfway won.
The idea of camlock leg vise is unique and ingenious and thanks for useful tip and detailed explanation.
Edit: This would likely fix the 'torque' issue with the tenon-bar.
Small suggestion for the foot-wedge - Cut a small triangular piece with the same taper angle, flip it around so it points in the opposite direction, and fix it to the bottom of the bench leg. This will keep the back of the wedge parallel with the table leg, and ensure consistent clamping pressure on both sides of the jaws.
“Fix it”? What do you mean?
Nail, screw, glue, rope? It needs to remain adjustable so I don’t understand “fix it”?
Oh ok. The second tapered piece!!! Sorry
I’m so impressed with this, John. The design is so clever, inexpensive, and functional. (Here’s one really good thing that has come out of this quarantine-period.) Thanks so much!
What a unique solution! I think I will build one just like this one, eventually! Great work and demonstration of the build process and functionality of it in use.
Nice product and great presentation 👍
Brilliant
John, great job! I think you have a winner! I am planning on building a jointer table and i am thinking that your design for the vice will be the right one for me. Thanks, take care and be safe!
I'm really excited to try building one of these for myself. I was curious about the clamping force so I did a quick comparison with a commonly used leg vise screw, which has 3 TPI. Basically I found that it is difficult for a cam lever to generate the same force as a screw with a 12" handle. If the cam changes radius by 1/2" over 120 degrees of rotation and your cam lever is 36" long, then it can generate about 2/3 the force of the vise screw (which is probably plenty!). The disadvantage is that force is inversely proportional to the change of cam radius, so if your cam changes radius by 1" then you only get 1/3 the force of the vise screw. I love the sawtooth solution for changing widths of boards, but the cam is still a little more limited in its range of motion than a screw, I wonder if it would be practical to place some shims or have dovetailed jaw inserts of different thickness to be able to add a finer adjustment than the sawtooth provides.
I'm working on a solution, I can now pull the vice in and out and clamp at any point, I have removed the saw tooth system and I'm now using an idea similar to a bar clamp. When the cam is engaged the vice locks and when its disengaged it is free to move in and out.
Love it
Very elegant! I wonder what you would think about exchanging the bottom saw tooth for a single pin through your mortise board?
Its pretty close to where it needs to be, so now its time to use it a see what needs improving.
Great job John!!!!
Awesome work. New to your channel, but over the past week I have watched all your videos. Great content and great work ethic! Keep it up
Thanks and welcome
Truly genius!
Genius John
If you had a vice at either end of the bench it would be great for holding extra long work 👍
Oops. Never mind l see you lengthened the tenon board. Great stuff!
That's fabulous John, amazing thing :)
Looks great John, look forward to seeing you making projects out of 8" thick timber 😉
Take care David
Beautiful job, John! Works nicely! 😃
Stay safe there! 🖖😊
Thanks 👍
Nice work john
Thanks 👍
excellent idea i have working o n a dedicated leg vise with no metal parts but i am having trouble making a 65mm wooden screw i may try your method well done
go for it
Hi Barbara, I am busy with a jig or two to cut such a big screw and nut with a router. But it needs a special router bit and extensive jig or two. This is certainly much simpler and quicker. We'll done John! Why did you not show this months ago before I started!?!
Impressive
"I think 8 inches is more than enough" well that made me laugh. :)
Just move your top saw tooth down to mate up with the bottom.
I posted this idea! Winning!
That’s amazing!!!!!!!! I’m definitely going to make one. Don’t have much plywood. Do save that for the ten on arm and teeth. What pitch were the teeth? Cheers
they are just a series of right angle triangles, 30mm across 20mm up
Is there a formula for the cam or is it trial and error to get your good tight fit?
John, nice build. Where in Ireland are you located?
Hi John, would you mind telling me what brand of low angle jack that you own and if you would recommend, regards Phil.
Its a Lie Nielsen no 62 and it's fantastic but not cheap.
@@JohnMcGrathManInShed thanks John, thought it looked a bit nice.
I am pretty sure you can still buy handbook with all details you need on woodprix.
Are you sure your an electrician 😂
I think so lol
