Title: Vice speed? handle
Post by: Spurry on November 22, 2016, 02:18:18 PM
Saw a glance of one of these on a Youtube video, a three-lever vice handle, and thought it would be interesting to make.

Having made the square hole for the vice shaft by using the lathe as a shaper, next job was the angled section. Not sure if everyone knows the dodge of a power top slide.

I replaced the small countersunk-head allen bolt, with a full-headed one. Chopped the end off a ball drive hex key and popped it in the drill.
This makes it a doddle to get a consistent speed across the whole of the angle, made more awkward with the top-slide handle being at the rear.

Must admit Pete i hadnt thought of that one, nicely filed away for future reference.

Good, i thought it would unscrew it  :clap:

Next job, to drill the three handle holes. There was a handy bit of 25mm WR mdf just waiting to be used for a little fixture.
Drew it up, then cut it out on the router. The two angled pieces hold the main piece at 18° off the vertical.
Prior to removing from the lathe 3 Jaw, I scribed a line across the angled face using a pointy-piece in the toolpost, and positioning a short length of bar under each chuck jaw in turn.

Looking good Pete


Looks like you made a cracking job of cutting the square hole  :clap: :clap:

By the way, you did not need to have the compound slide handle at the rear. You could have spun the lathe in part in reverse, cut on the far side of the piece and feed from the front.

I hope you understand what I mean.

Thanks for the comment Rob.
 
Jacques - that was my first thought too. But the cross slide ran out of travel, as well as exposing the cross-slide screw to the anticipated swarf. If enough time had been spent experimenting, with tool reversal, spinning the tool post etc., it is possible there would have been a method. The easiest for me, was to spin the cross-slide backwards (for want of a better expression).

Graham - lest I forget. I did not give the reversal a second thought until I read your post. The cut was carried out with the screw moving clockwise, and only dragging when in reverse. I have been using this stunt for some years, and it could well be that the screw is secured with a little Loctite. :-)

Your interest is appreciated.

Jacques - it also depends on how the chuck is mounted on Pete's lathe, whether it would unscrew when run in reverse.

Well (not being able to resist), my "vice speed" is usually accomplished with rolling papers and flue-cured tobacco.

I have a set of vise "speed handles" made a long time ago.  What I "discovered" many years ago is to install a spring plunger to maintain pressure when a (slip fit) handle is used or they decide to take flight at the most inopportune times.

Handle finally finished. Main problem was trying to decide on the length of the bars. In the end, I decided on the maximum they could be, without interfering with the Y feed. It works really well to move the jaws from fully open to closed. Only downside is the weight, (but that might assist with the inertia to spin.) I was going to drill a complete set of 12mm holes, but could not calculate the angles and depth when they would start to break into each other , so interspersed the 12mm's with 6mm holes.
As I have yet to work out how to put words between photos, here's the list:
1. position of handle when jaws fully closed
2. back view
3. front.
4. clearance shown dictated max length of bars.

As yet, there is no sprung-ball retainer, (as advised) but will try without, and hope the experience is not too painful.  :palm:

Pete,
Looks to be a fine piece of machining and very functional too....  :bow:

Thanks for the comments. One has to make a bit of an effort in view of the high standards portrayed round here.

Nice job Pete. Looks like the one I made many years ago.

Maybe this tip can help you...after the n'th time having the speed handle speed drop on top of my feet, I counterbored a rare earth magnet in the bottom of the hole to help it stick to the vice shaft. Hasn't been a problem since.   :beer:

I have a set of vise "speed handles" made a long time ago. 

As a famous British celebrity* said not so very long ago (when explaining that in British English, the "hood" of a car is called a "bonnet", someone called out that a bonnet was a kind of hat worn by babies and ladies in the Wild West...

...to which our hero** replied - "We British are totally capable of understanding that the same word may have two completely different definitions!"

i.e. in British English - vice = a device to clamp work to a bench/milling machine/shaper/whatever. Or drugs. Or even pornography, that's considered a "vice" here.

Meanwhile, the word "vise" does not exist! Similarly tires, aluminum, oh - and the thing that goes over the engine of a car? It's a bonnet! A hood is the thing on a coat that keeps the rain off your head!
