<div>Hi Joe,</div>
<div><br>
</div>
As Bob pointed out, the easiest thing to do, is to remove the old tweezers and replace them with a new set (they are dumont style L5 tweezers, and you can find them in EMS, part number <span style="background-color:rgb(255,255,255)"><font face="Arial, Helvetica, sans-serif" size="2"><span style="line-height:19.200000762939453px">0508-L5-PS). </span><span style="line-height:19px">You</span><span style="line-height:19.200000762939453px"> will
have to mill them to fit the brass piece and make a hole, which is a tad difficult because they are made of kriptonite or some similar material. Of course, it is critical to place the hole at the proper location. If you want to have some more of the brass
pieces made, it is a tad more expensive, but it can be done in any machine shop that has EDM (any decent Engineering Department has one). The brass piece should cost you something in the order of $120 and the tweezers another $50, so in total you should be
able to have them made for something ~$200.</span></font></span>

<div>Dear all,</div>
<div><br>
</div>
<div>I am thinking to make the customized tweezers for Vitrobot Mk III as the commercial ones are over my budget. Does anyone have a blueprint that can be kindly shared with?</div>

<div>Thank you and best regards,</div>
