I own a tuna rail gun and was gifted a MVD roller head. I watched this video and to drill the hole he first suggested that you need a 3.3mil drill bit. Then he suggested that he should have used a 4mm drill bit. I have the 4mm drill bit from attaching the anchoring screw at the grip of the gun. Can I use a 4mm drill bit to drill the hole for the screw already in the gun. Making sure before I even take it apart. Which size hole punch and screw would I use.
will this work well with spearshafts that do not have the shark fin? becasue I think the rob allen shafts generally come with the cut notch not the shark fins
It works fine with both, I have used both notch and finned shafts. I ma currently running 174ph Triple Finned 7mm Cressi shaft and I am very impressed with the it,
