Vise mounting location & mystery screws

[ChicagoJeff]

I bought a 4" Vevor vise for my LMS 6500 and have two questions:
1. How do you decide which of the 3 table slots to mount it in?
2. What's the purpose of the 2 Philips head screws shown in the 2nd picture?

1) Mount the vise so that you can reach the back side of a part held in the vise with a 1/2" end mill (inside face of the back jaw needs to be in front of the front edge of the 1/2" end mill).


2) The screws keep swarf & dirt out of the holes, which are used to relocate the jaw plates to the outside of the body, increasing the size of the material you can hold. There's another set on the back (fixed) end of the vise. I'm assuming that the vise's jaw plates are secured with SHCS on the inside faces? These screws would be used to attached the relocated plates.

I keep tall jaw plates "permanently mounted on my 3" vise:


I also knock sharp corners off of things to reduce the opportunity for cuts & gouges in my hands.

They can also do double-duty and hold a "ways cover" in place if you want to keep swarf off the vise screw.

Hadn’t thought of that, but have used them to mount swarf shields to keep chips from flying everywhere:



Since the time of the photo I posted above, I added a single tapped hole in the tall plates for this purpose:

I suggest sawing off the coolant trough on the side facing the column! You won't regret that extra inch of room on a small mill!!!

great idea! You can then mount the vise upside down and mill the saw cut so it looks nice...

However -- You should check that the bottom is still flat after cutting the lip off... taking that lip off can release stress in the casting and allow it to dish. Only happens a small part of the time, but is worth checking.

- your mill table is good enough to act as a reference if you don't have a surface plate. You will need to buy and learn how to use Prussian Blue to accomplish this.

Actually, if the Vevor vise is anything like my 3” that lip barely extends past the rear jaw plate when mounted on the back of the fixed jaw. Also, Y- travel will stop before the lip comes close to the column with the vise positioned as I suggested so the back of a part can be reached with an end mill.

Suggest you check deflection of rear vice jaw when clamping something in vice. I have one similar to that I got from Grizzly and the rear jaw deflects in the range of .007 throwing off milling accuracy in "y" axis when doing production type milling.

I have the 3” and 4” and neither are a problem mounted in the center slot.

Then again my mill is partially home brew.


Op, how was the packaging and overall condition of your vise upon arrival?

Mine was bad enough (both damaged and manufacturing defects) I got two refunds from vevor, so I basically paid $22 for it.

For $22 I don’t mind the ding and the handle that was totally fubar from a manufacturing standpoint was repairable.

Packaging was scant to say the least.

I guess I was lucky, UPS didn't damage anything. I purchased the 4" version with the 360 Degree Swiveling Base and put the base in a drawer.
Packaging was pretty minimal with just a cardboard box and a layer of Styrofoam only on top.

Thanks to all posters for sharing their knowledge. I wish I took machine shop in high school 50+ years ago.
