Well, the mini vice mount Hi-Vice gets pretty much constant use, so it’s time to make a nicer one based on the prototype. 

Pretty happy with the design, but may as well make some changes to it for the final one.
1)        About an inch higher 

2)        Hardwood so it doesn’t vibrate 

3)        Slightly wider jaw 

4)        Bottom nut a little bit bigger to make it easier to spin 

5)        Some king of anti-rack mechanism 

6)        Detachable piece for clamping straight to the bench 

So, not really any exact kind of plan, just a rough idea, I know where everything needs to be and I'll just wing it from there. 

A lot of the process is the same as the other vise, so I'll keep it reasonably short.

Cut the screws first.
Had some ¾ birch ready done, so thin some of that down to ½ inch and make Both threads.
I made more later, but same process.

Dimension the sections for the body.

Drill and tap the holes, I decided to go with 3/4 inch threads for both the main screw and the guide screw.

Make a cutout on the main thread for a garter.

Make the garter, needs to be tight enough to hold on to the screw, but flexible enough to go on and off easily.

And cut the slot in the vise body for the garter.

Handles are spalted beech with a walnut cap.

Nothing too fancy, just shape so they will be easy to turn.

Glue on the walnut caps and shape

Oil them so they don’t get dinged up while building the rest.

Mark up and cut out the spots for the bench mount.

Make the bottom, detachable, mount – it’s about here when I realised I should have put a shoulder on it for a more secure connection. 

Ah well, cut the shoulder and patch the body, use a bit of walnut to match the handles and I can pretend it’s intentional for decoration.

Mark up and cut the profiles on the arms.

Just use rasps and files to shape.

Drill and tap the mount screw and mark up the profile.

Drill the hole in the body for the holding screw to go through.

Drill and tap the hold in the mount for the holding screw. Tapping the thread int end grain, which is generally a bad idea, but it shouldn’t get too much hammer and if it strips out I can always patch with a piece (Which is probably what I should do first time, but I’m kinda curious to see how it will hold up – It’s Ash and the threads are fairly course, so it might be fine)

The hole looks OK, I’ll give the inside a couple of coats of oil before tapping it. 

 

 Shape the mount.

 Cut out a spot for the jaws and finish the shaping on the main body.

Add some walnut to the arms to act as a shoulder. 

And that's the main body done, so glue the arms up.

I decided to add a jaw to the mount screw at this point so it wouldn't ding up anything I attached the vise to.

Which needed a matching hole cut out so it would still retract enough to fit onto my bench.

Quick test, everything works as it should.

Shape up the front

And add the jaws

Some leather for the jaw faces.

OK, so this was the plan, everything covered off.
1)        About an inch higher 
Done

2)        Hardwood so it doesn’t vibrate 
Done in Ash

3)        Slightly wider jaw 
Done

4)        Bottom nut a little bit bigger to make it easier to spin 
Spins with a flick of a finger.

5)        Some king of anti-rack mechanism 
Added a screw into the vice jaws

6)        Detachable piece for clamping straight to the bench 

Done
This is the anti-rack screw, works well.
