Vise for a G0704

[hive8]

I am in the process of buying a Vise and Parallels for my G0704, i was wondering what would be a good vise to choose.

I saw that Glacern is running some deals right now. Also should i go with a 4" or 6" not sure if the 6" would be to big on the G0704. If 6" is good i think i would like to go with the Glacern GPV-615.

Also what other good choices are out there, i saw some on ebay like these

or

Shars Vises on ebay.

Please anyone has some info let me know.

My dad bought a glacern, but I think it was a 5". Either way, a beautifully made vise! He does have two 4" vises, I'm sure he would sell one, one is new, but had some stains on the top, the other is a genuine Kurt . 6" would be mighty big on that mill IMO, his is a small Bridgeport type, and the 5" fit perfect.

can you email me please with some details on the 4" vise... my email is anton8 "AT" gmail.com. Price and some pictures also some details on the dimensions and accuracy would be nice.

The general consensus is that 6" is too big for these mills. Some people consider 5" too big, some are happy with it. I have a 5" shars and it can get in the way depending on how you mount it. If you mount it in the center t-slot, the vise hangs off the rear edge of the table and limits your travel. If you mount it in the front t-slots, a lot of the vise will hang of the edge. Attached is a pic of my 5" vise mounted in the center t-slot of my G0704 for reference.

I have a 4" and it is a nice size for the G0704. In my opinion the 5" would be too big and the 6" is definitely too big. I would post some pictures but my G0704 is torn apart.

Also consider that you can move the movable jaw to the other side of the ram to clamp larger stock. I made some stepped jaws from 1" thick steel stock that have steps on both sides of the jaw. The ledge on the jaws places the bottom of the stock 0.2" above the top of the ram on the vise. Just the other day I was milling some parts from 6" wide stock on my other mill using the 4" vise and the stepped jaws. I am out of town right now but could get you a picture of the 4" vise holding 6" stock on the stepped jaws in a couple days.

Don't think he has an accuracy report on the new 4", the Kurt would be quite accurate, but $$. I'll see of he can send pictures.

I don't need a accuracy report , if you give me a model number then i can check on the website and get the specs from there...

Since LittleMachineShop.com is close to me i was thinking of picking this one up:
LittleMachineShop.com - Vise, 4" CNC Mill

Any other suggestions

Here are those pictures of holding 6" stock on a 4" vise. Excuse the chips. I had just finished cutting out some parts for my G0704 when i got sent out of town suddenly for work. Also excuse the rust patina on the vise. The vise is 15 years old and has seen several moves where it was in unheated storage and my shop is also not heated all the time.

Anyway, the pictures show a piece of 6" wide 6061-T6 bar that I was cutting out parts from. I can't remember for sure, but I think I had 8" stock in this vise at one time mounted like this 6" piece. You can see the stepped jaws which are made from 1" thick steel stock. I don't remember the height, but the step is about 0.2" tall with a 0.1" wide ledge. With a piece of stock mounted there is about 0.2" clearance between the bottom of the stock and the top of the ram portion of the vise. I have steps on all side of the jaws so that I can use them in different locations. You need steps on both sides because of the counterbore for the bolts. For example, the fixed jaw can go on the opposite of the mount on the vise to provide a step for stock probably up to 10" wide. Likewise the moveable step jaw can go on the other side of the ram for narrower parts. I milled the steps with the jaws mounted on the vise with a block clamped below where the step was milled. Hope this helps.

109jb thanks for the info and the images... yes i comes back to my memory now, when i was at my internship we used jaws like that, I actually made it myself on a mill then surface grinder, we did the whole process, of getting the steel, cutting it with like 0.3mm more material so we can go and surface grind it. Then we put it in the oven to harden the steel, let it cool, when it came out was all black. Then we had to precision grind it to dimensions.

I wish i had all the tools i had at the internship, i start missing these. Special a surface grinder doesn't need to be CNC, manual would be fine... I think i start looking around how much manuals are going for...

Another shot of a new Shars 4" vise for you as well in case you wanted to see what that (specifically) looked like on the G0704.
