You will use a fair amount of tape and glue. When I made a pile of Batarangs a while back I went and found ~4” wide blue tape which made it easier. I screwed down the sheet for Op1 but that required an Op0 to prep the material. In that project it was worth it.
Do you have MQL or Flood coolant? For MQL you can use blue painters tape but for flood you need powder coating tape.
If using blue painters tape then you can pop the part of the fixture with a putty knife when you are done. The CA glue technique is strong in shear but will pop up with a fair amount of prying force. I haven’t worked with powder coating tape yet.
Taps is a check box in 2D contour type operations, depending on your CAM option. I use Fusion360 and it is right in the tool path generation.
Your soft jaws look pretty solid, you might have to get creative with the long jaws so they don’t flex out on you. I highlighted a few areas to pay attention to:
- Orange: make a relief on the inside corner, don’t follow your part geometry exactly.
- green doesn’t need jaw material there.
