How to Improve an Import Machinist Vice For £10 #vevor

#vevor #machining #unboxing #vice
Join me in this Video as I Unbox and take me first look at the Vevor 6 inch Machinist Vice. With the Vice inspected I found a few areas in which I felt the Vice needed improving so that's exactly what I done. Stick around until the end to see how I made the operation of this Vice 100X better for only £10.

A Belleville washer under the fine adjustment nut is usually all that is required to take out the play. A demonstration is on my channel. My hardened thrust washers were £1.43 each. You will need a thrust bearing on the other side, a proper one. Mill out the rads with a smaller cutter to give enough flat and the job is done properly.

The needle bearing you have does nothing for you when tightening the vise. It only lets the screw turn more freely when opening. You need to try again to put a bearing on the inside. Perhaps by mounting the vise base on the lathe cross slide (fixed jaw end on the right), with a boring bar in the chuck, and back boring a spotface for a bearing seat.

Also to add to this cool video is always a good idea to spray your vice down and bed with some WD-40 if your going to be away from the machine for more than a week or two. It will keep it from getting any rust

10:30 the barring is on the wrong side of the casting. You had it right the first time. Just mill more material out of the way. Or just chunk the vise and get a KURT.

[WoLpH]

That's how I view devices made to Chinese standards as well. They're producer goods, it's a good base but it needs a little work to become a good product. A 6" Kurt vise will be at least 6 times as expensive so depending on much your time is worth (and whether you like doing these modifications), this is a good deal.

Surely the force on the leadscrew will be on the inner face when the vice is tightened? I've got a Vevor vice on my mill and to be fair, it was just fine out of the box. For the money, they are hard to beat. Very impressed with the quality of the grinding and the general flatness and tolerances when measured on my surface plate.

[rovirjm]

since you have a surface grinder, consider truing and flattening the bottom so it aligns with the jaws riding surface.

Hi George Clements
Almost all machine vices have jaw lift, but these vices are of the KURT design.
The sliding clamp jaw has hemispheres pressure pad which provides downward force when clamped.
One of the main problems with jaw lift is over tightening the vice.
You have to select a vice which will cope with the forces generated by the cutting process.
These are Hobby vices, which generally mean they should be used on hobby machines (normally low power)
I'm not trying to preach to you or be clever. Im just trying to be realistic regarding what we are all buying?

I like this upgrade. The washers really nead to be hardened washers.

[Dogfather]

I suggest adding 20% to the budget and purchase the hardened races that are normally available with thrust bearings. If you were able to part off the steel used for your DIY washers they weren't hard enough and will deform under load.

[Dogfather]

When you buy thrust bearings your supplier can also provide hardened thrust washers that are typically used with them as an assembly. Soft steel washers could go on either side of the bearing assembly if needed, but if they're used alone they may not last long due to the high tightening pressures. I believe someone else may have mentioned also that the thrust bearing assembly needs to be fitted to the opposite side of the casting (the side toward the fixed jaw). This is how a Kurt D675 is built for example. That vise merely has a thrust washer at the handle end of the screw because there is no significant force on that end. Hope this is helpful.

[thehobbymachinistnz]

Good mods on the vice, well done. You could machine up a smaller diameter brass washer to fit where the other thrust bearing got damaged. That should help reduce the friction when clamping items in the vice.

[dennythomas]

With those vices I'd be more concerned with flatness and parallelism than the lead screw. And fortunately you have a surface grinder to address that issue. If you haven't checked it yet, your going to find it out by at least .002 to .004 (or more) side to side, front to back.

[erikev]

Thanks for the video. Me thinks the work you did on this vise is of much inferior quality than the original quality. Drilling the oiling hole too big. Is it even necessary? Machining off a lot of material i the most stressed area of the vise, much of it unneccesary. Poor work causing bearings to fail. I would give Vevor a B-, and you get an F

[lucasandri]

The oil port is a good addition, i would make a brass or even better a bronze washer to put on the lead screw because when you'll tighten the vice the screw will rub against the cast iron.

[michaelnicholson]

For interested viewers, the Arceurotrade accuvice has these mods as standard. That is not to say they are free from requiring a few tweaks.
Deburring is #1 issue. Second is the ""swivel pin" between the vice and the base.Rebore it and make a new shouldered pin that is within a decent tolerance.
Third is making sure the hemisphere pressure pad is free to swivel in the slid
Forth is the tenons are " let's just say" inadequate so make some new ones to fit your machine table.
Measure your table slots as they are unlikely to be 14mm you might expect, unless you have a non Chinese mill!
Lastly " come on" for the price you have got to accept the fact that you need to finish off the assembly.
Other than above, I'm well satisfied with the product and would buy another one tomorrow.
I'm Not sponsored by Arceurotrade, I'm just reporting my findings, and I believe that they represent very good value for the money.

Some newer designs don’t have an oil fitting on that bearing. You really need to find out before you start modding designs. The new Kurts, for example no longer have that oil fitting. They don’t need it.The most important thing to check on these cheap imports is to indicate all the surfaces to find out how badly the surfaces are off from parallel from the table and everything else on the vise. Changing the bearing doesn’t do much. And, yes, that vise is much too large for your mill.

[robertalbrecht]

Open thrust bearing are no good!! How you keeping the chips out? They will be destroyed in no time!!

[DaveNorthWest]

Anyone know where to get a STEP or STL or other cad file of this Vevor vice in the 4" model? Or dimensional blueprints of some kind? Id like to make some soft jaws for mine and also be nice to have it in my cad software for setup view. Thanks

[Lesfac]

To be honest I think the vice would have been fine as supplied. I would take the view it's better not to put crushing loads on a small bearing. ( You didn't anyway on the bearing that would have taken the main clamping pressure.) A bit unfair on Vevor. It would have freed up with a little use.
