hmmm intersting idea , the next thing to improve wide clamping is to siamese two vices together

I have to make do with what I have :) I've considered adding holes towards the outer edges, outward from the vise, to receive bolts, to add just a little more clamping force. So far, has not been needed. Take care

Hi we see you extended the vise jaws to hold longer plate material, it is a good idea for your fix, we use a vintage Kurt 3.00" vise so we could do this to ours as our work is so much smaller. Good share. We like your vise jaw stop as well comes in handy. Lance & Patrick.

For light work holding Umbau's table mounted vise will work Kent. But there's at least a few threads on the Practical Machinist forums pointing out the industrial versions of his idea are more than capable of bowing the table on a Bridgeport. To use that type of table vise on a much lighter mill I'd want to have an indicator on the table ends as the part was tightened in place. It takes a whole lot less force to bend a mills table than most might think. It won't permanently bend the table, but it can start to bind and then put excess wear on the dovetails, feed screw nut and in your case stepper drive.

Thank you for pointing this out, I would not have thought of it, and it makes perfect sense that without the massive vise bed, the table is going to distort. Very interesting!

@@kentvandervelden Yeah I was in the tool dealers cash in hand wanting to buy one of those milling table vices some years ago. They were out of stock though. Not long after I spotted the first thread on PM about them distorting the tables if your not really careful. Machine tools can have some unexpected results with what your adding to them sometimes. I wouldn't have thought of it myself without those PM threads detailing the issue. With a big heavy duty cnc bed mill they would probably work real well. For light tightening and work holding on our lighter weight mills they should be fine, but for what I would have been using one for it would have been far past light. My mills manual and a 3/4 sized Bridgeport clone, so a little bit larger than yours. I bought a matched pair of these. www.glacern.com/gpv_615 if it fits within there jaw opening it's a good fairly expensive and a bit heavy way to go since a pair of them weigh about 170 lbs. I think your extended jaws should work well enough for the part sizes you were doing. A couple of C clamps on the ends would stiffen things up a lot if you ever run into a chatter issue.

@@kentvandervelden sure is, I want to try it with my 6inch vise, I scraped a big part the other day due to chatter . You have any tips on milling the bolt holes?
@kentvandervelden
@kentvandervelden 4 года назад
@@PepeCheizen Bolt holes will be no problem and could be done on a drill press if needed. If you don't need the step, even simpler. Want to have pieces that are square and parallel, but one could bootstrap those if needed. I considered adding holes for screws to clamp at the ends, not in contact with the vise jaws. Might be useful. I use large clamps instead.
