The clamp bolt (M6) was not very good on my 2 inch vice so I replaced it with a decent one but I've since made a new "toggle" or whatever you want to call it and am now using a M8 clamp bolt instead -
Hi Vic
I also got me a 2 inch (in about; in Europe its a 50 mm ) version of a screwless vice. I still use the original M6 bolt though i first thought it might be too weak. And even if it comes from china, it is really working fine up to now.
Before using it, i did following modification (Anko: That may be useful for you too...
)
The ball cup in the clamping jaw had a very rough finish on my version. I then fixed the ball washer on a piece of 6mm steel rod (the hole is 6mm) so the rod does not come out on the ball end. (May use glue, a wooden mandrel made wet so it swells or Just press fit a brass or aluminum rod in the washer... )
After this, i've put some lapping compound into the ball cup and chucked the ball washer into my accu drill and looped in that washer by changing its direction permanently (to be shure the ball cup gets fitted to the washer on all the possible clamping positions)
Now the surface of the ball cup is really smooth as the ball washer is too.
Also he washer can now adjust to the right angle easily and really smooth.
Oh and one last hint: If you dont want all the chips to stick on the oiled/greased ball cup/ washer then use some powdered pencil (the softest one you can get)
Thats really working good because the pencil is made from graphite and other stuff (the softer the pencil the more graphite it contains...)
Cheers
