→Appendix 2: How To Fit a Spear Head
:5. You may find that your spear socket is too wide to fit onto your spear shaft (Fig 5).
:6. Fix the lump hammer in the vice, we will use this as an anvil (Fig 6).
:7. Using light blows with the ball peen hammer squash the socket until it fits the spear shaft snugly NOTE: if your spear is made from spring steelyou will probably not be able to do this. When hammering like this always make sure that you hammer straight down to stop the spear head from kippingoff. If you need to hammer a different side turn the spear head (Fig 7).
:8. Fix the shaft into the vice.
:9. Drill through the rivet hole in the spear socket. If the drill bit does not pass perfectly through the hole on the other side turn the spear over in the vice and drill through the other side, this usually causes the holes to line up (Fig 8). Your rivet should fit snugly in the rivet hole in the spear socket. The hole in this spear is 5mm diameter and the rivet is a 100mm nail which has a diameter of 4.5mm. The hole you drill should be 0.5mm
bigger than the rivet you are using to ensure it fits as tightly as possible.
:10. Put the rivet through the rivet hole and mark the bit sticking out with the marker pen (Fig 9 & 10).
:11. Place the rivet in the vice and, using the hacksaw, cut it down along the outside of the pen mark (Fig 10 & 11). There are formulas for workingout the proper length of metal needed for a rivet head, however I have always found that the width of a marker pen tip is sufficient metal for riveting a spear (Fig 12).
:12. Take the spear head off the shaft. Remember which way it went on to make sure your holes all line up.
:13. Mix some of your favourite 2 part epoxy resin and paste it all over the shaved part of the shaft (Fig 13). The epoxy strengthens the join and helps prevent the spear head from rattling as the wood dries out.
