    Congratulations on great dovetails, I'm envious! Photos like those are a great incentive to just go out and practise some dovetails!

    Nice yarn too Ray, thankfully dad's pretty computer illiterate, so I don't mind saying that I'm enjoying some time working with him at the moment!

    Keep up the good work,

    Cheers and beers,

    Muzz

    Hi TruckieMuzz, artme, pampelmuse, moikel, Justin, IanW,

    Thanks for the words of wisdom, I'm now looking for an opportunity to use the words "Only a nong would do it that way" with any luck I won't have to wait too long..

    As to the moxon swin screw vise, I can't see how something so simple and yet so effective hasn't become more popular..

    Regards
    Ray

    Been thinking that meself.

    I can get fairly wide boards in my home-made front vice, so I tend to use that when dovetailing smaller drawers, etc. For years & years I did wide boards by clamping them to the apron of the bench, which was an awkward manouvre, and didn't always hold tham dead flat, making transfer of marks from the tails a dodgy business.

    But the twin-screw, on the bench-top vise is the answer, alright. The 50mm thick Kwila front jaw on mine doesn't flex, & clamps boards dead flat (you do need to beef up that front jaw on yours, Ray! ) The other big advantage is getting the job up higher, where age-challenged eyes can see it. I'm thinking that can do with a bit more of a boost in my case, and am plotting Moxon Mark II, which will be a bit taller, and have a better system for quick mounting & dismounting to the bench. However, given that Mark I works pretty well, it may be some time before Mark II makes its appearance (if ever).....

    Cheers,
    IW

    Hi Ian,

    I like the way Derek did his with the "wings" on the side for clamping, I might pinch that idea.

    One other idea that came up on another forum, was to slightly camber the inside of the jaws, like you would for a clamping caul, rather than perfectly flat jaws.

    I was demonstrating the twin screw vise to a skeptical friend the other day, and you put a board close to one jaw and do it up finger tight on the screw. Then invite them to tighten the other screw finger tight, then ask then to try and move the board... For some reason they are surprised to find it's clamped so tight that it's impossible to move...

    Regards
    Ray

    Ray - yes, I think the side wings are a very good & simple way to hold it firmly. I was looking for a way tp hold mine that would be simple & quick to mount & dismount without clamps sticking out from the bench & getting in my way, so I used bolts through the dog holes. This gives a very solid attachment, and nothing gets in the way, but takes longer to set up than walking across to the clamp rack for a pair of clamps. For light work, clamping it with the tail-vise works ok, but when I lean against the work more heavily, as when cleaning out half-blind dovetail sockets, it has a tendency to rock back, which is a bit disconcerting. I think that problem can be cured fairly simply by adding a wider sub-base. This will lift it a bit higher, too, which won't do any harm.

    That would help a lot if the front jaw is a bit flexible, like the one you have now, and save you from having to hold the job & wedge & tighten the screws with just two hands. I prefer the jaw to be straight & stay straight under load, so I'd just find a thicker piece of tough hardwood & drill a couple more holes...

    Yairs, I have seen similar expressions of surprise when demonstrating wooden clamps. Lots of folks seem to think they are delicate things, not capable of generating any real pressure. So I have often had the satisfaction of seeing the eyebrows go up when I clamp one to a bench top & ask the sceptic to move it. Unfortunately, the inexperienced DO snap the inner (tension) screw by trying to tighten the jaws way off parallel - they don't like that!

    Cheers,
    IW

    Good Morning Ray

    Lovely saw, lovely dovetails, lovely box design, lovely execution and an absolutely fascinating end vice.

    Note your comment about the use of a sticker to overcome jaw flex. Ian is probably right when advocating heavier jaws and a stiffer timber, but I am unsure if the colour variance with kwilla would qualify as a design feature, or would a lighter-coloured but equally tough would be preferable.

    Noting that stiffness increases with the square of the thickness, as a temporary measure, you might consider adding a couple of 30 mm battens to the outside of the jaws as stiffeners.

    Cheers

    Graeme

    I have not made a Moxon Vise as I considered that Jeff Millers " Benchtop Bench " would provide greater flexibility of use. A couple of ideas I utilised in this that could be useful on the Moxon were firstly to put a camber on the front Jaw which from memory was around 0.5 mm across the overall jaw length of 900 mm. Secondly, to hold the bench in position I put four 5/16" "T nuts" in the underside of the cabinet top on which the bench sits. Then it is a simple matter of fixing the bench to the cabinet.

    I have found this small bench to be very useful, and although it is very easy to move, it now seems to have taken up permanent residency on top of the tool cabinet.

    Regards

    Hi IanW, Graeme, Basil,

    Thanks for the comments, the current plan is pretty much as you've described, heavier jaws and a little camber, I guess the heavier the Jaws the less camber.

    That bench on a bench is something I've always thought is a great idea, it brings the work up to a height where you can do fine detail work. On top of the toolbox, it becomes another smaller bench!

    Regards
    Ray

    I find the vise very useful for all the jobs you would normally have to bend over for on the main bench, as it saves the back. Plus it aids with accuracy as you can see things much better.

    Before going to the trouble of making a thicker jaw. I suggest trying a camber of .5mm or so on the existing jaw. My jaw is 40mm thick and with a board of 600 mm wide I only have to tighten each screw finger tight, then give it an extra 45 degree or so tweak and it holds the board so tight the cabinet will move before the board will.

    Regards

    As the Septics would say, 'I need one of those!' I think it would greatly improve my work, but unfortunately I don't have the space to store one when not in use.

    I know you believe you understand what you think I wrote, but I'm not sure you realize that what you just read is not what I meant.

    Hi Ray,

    I'm a little late, summer Holidays. Thank you for posting this. Next time when my son asks me, why I'm making just another saw, I'll show him this thread!

    Cheers

    This makes me want to sweep away the swarf and smell the wood again Ray. Thank you.

    Thanks Bob and Pedder,

    Josh got his match planes to do the tongue and groove joinery on the bottom of the blanket chest last week, so I'll update this thread in the next few days with few pictures of his progress.

    Regards
    Ray

    PS, having never used match planes before to cut T&G, I'm impressed at how quickly you can get nicely fitting joints.
