For U-teams and HS teams with a metal lathe:
On Team VIRUS: MCCC, we have a little collet to hold HS shafts in our lathe for turning and end drilling/tapping.
If you would like one of these collets for your own team, read on:
If you send us a pre-drilled chunk of hex bar (3/4” long, drilled on your own lathe with “G” drill), we’ll broach the hole square for you (using the same broach we use to make the HS Lock Bars for robosource.net). No charge…except a couple bucks for shipping. Contact us through the VEX Team 3547:VIRUS facebook page, or message me personally through the VEX World Coaches Association | Facebook facebook group.
