Machinist Vise Stop... ( Clamps on Jaw )




These are directions on how and what you need to make your own vise stop
 for a kurt style vise...
  I did it at the Tech Shop in San Jose California....

  Gabriel Aceves....

Step 1: Step One... Materials and Tools...

You are going to need one piece of .625  x 1.50 x 1.125 inch steel bar stock...  One .500 inch endmill capable of cutting steel...
  A .159 inch drill bit... 10-32 cut tap... Two 1.0 inch long 10-32 cap screws...  One Tap Handle... 
A milling machine...  .5 inch collet ...  Mill drill chuck attachment... I included a rude handdrawn print in the pictures...

Step 2: Step Two... Blanking Your Material...

So you are going to want to start out with .625 x 1.50 cold rolled steel bar stock and cut off
 a piece that is 1.125 inches long.... Deburr your cut edges so they
 do not get in the way later...  You may want to cut a few extras, stuff happens...

Step 3: Step Three... Squaring Up Your Material...

Now we are going to start cutting our parts with the milling machine..... 
We are going to use two of the stock dimensions and only alter the 1.125 dimension...
First you are going to make a side cut to square up one edge... 
 Remove about .05 inch or so from one side as shown in the picture... 
 next you are going to flip your part with the other saw cut edge facing up and cut it down using the tip of the endmill...
 Until you reach your finished dimension of 1.00 inches...  Make sure everything is square because this
 is a tool and you always want your tools to be perfect because your finished product can only be as good
 as the tools used to produce it...!!!  Dont forget to deburr your newly formed burrs...!!!

Step 4: Step Four... Cutting the Slot...

Now we are going to cut a slot in our part as shown to the dimensions listed...  Again it is of utmost importance that everything is square and parallel....  Your slot does not need to be perfect...  So if you are .02 or .03 to big or
to deep dont worry your stop will still function...  just keep it square...

Step 5: Step Five... Drilling...

Now we are going to drill our .159 pilot holes for our 10-32 tapped holes in the locations shown...  Locations of these holes
are some what important so try to get them as close to the dimensions shown....

Step 6: Step Six... Tapping Our Hole...

Now we are going to tap our 10-32 holes...   Try to get good quality holes because these screws are going to be
 loosened and tightened often...  Use cutting oil...!!!

Step 7: Step Seven... Assembly...

Now we are going to screw our 10-32 cap screws in to the tapped holes as shown and now you have a new
 vise stop...   I did this at the the Tech Shop in San Jose California...   Gabriel Aceves

    You are aware that y'all are fighting over vise stops, right?

    Pitiful. It looks square to me, and I am a machinist by trade. CNC is a waste. If you can't work a manual lathe and mill, and do the formula(s) yourself instead of letting a computer do it for you, you don't need to call yourself a machinist.

    My boss had something similar years ago. His had dowel pins installed on each side for a single point contact.

    Now I have to ask, how do you use your stop? When I posted the stop I made I put up a few pictures of how mine is used.

    My vise stop is far from perfect, but it stops work precisely every time. Because my vise stop has one thing going for it, it is made out of solid matter.

    The first rule of machining is, never make anything closer tolerance than it needs to be.

    You put the rear jaw inside the large
    Slot with the screws facing backwards towards
    The rear of the machine and tighten the screws
    To secure the stop...
    I am a machinest by trade and the
    First rule i learned was measure
    Twice cut once... thanks for
    The input... Gabriel ...

    I guess the guys in the QC inspection shop are going to be bummed to hear about your theory. It sounds to me more like what a roughing carpenter would say than a precision machinist. I did enough time in a union tool and die shop to know that nothing gets measured twice then cut only once. OK that's not strictly true, we tossed out a lot of parts like that.

    What ever... your superior and I'm inferior... you win I lose...
    Its just a stop... anyways you know what opinions are like right???


    Reply 7 years ago on Introduction

    It is, "you're superior and I'm inferior." But you are on the right tack now. Although I do not expect you to know just how right you are with that statement. My opinion is qualified when it comes to machining.

    Enough that I could see from your setup that you do not even know how to square up stock. But I was being polite before not bringing that up. I guess we can drop the pretenses now.

    Site policy forbids me from voicing my true opinion of you. You can be assured though that it is on the low side, and your childish outburst has not ingratiated yourself to me either.

    My stop is way better than yours is, but thanks for playing you shoemaker ha ha.

    Whatever... give it a rest... its stock material... say what you will
    but I know the truth... are we gonna keep going back and forth...
    I was being sarcastic ... I'm way better then you...

    No, it is, "I am way better than you". Then is after the fact. As in now and then. Maybe this will help explain it to you?

    What do you kids do with your time to grow up so ignorant? Crack a couple books in your life why don't you?

    I just made a plate to mount a stepper motor on. Here check it out. It is for the Z axis of my CNC router I'm making. Pretty cool huh?
