Steps

Step #1: Prepare the hammer

  • Drill or punch the hole in the flatbar.
  • Weld the two pieces of flatbar together
  • This needs to be a really strong weld! The hammer will be under a lot of stress, and if it's not a solid weld, it could fly off! (This is why the guard is there).
  • Tack the shaft into the hole so there's about a 1/4" distance between the end of the shaft and the opposite side of the hammer.

Step #2: Couple the shaft

  • Cut the coupler down so it's 2" long. It doesn't matter from which side you cut it.
  • Get the shaker motor, the mount you made, the shaft/hammer, and the coupler.
  • Put the shaker motor onto the mount and couple the shaft to it. Mark where the shaft enters the coupler.
  • Make sure the coupler won't be rubbing on mount while it spins.
  • Make sure the hammer has about 5/8" clearance from the mount.
  • If not, you can pull it out of the coupler a little, but make sure the bolt won't be too close to the edge.
  • Otherwise, you can grind away the tacks on the hammer and tack it properly.

Step #3: Drill hole for bolt in coupler

  • Remove the motor and shaft from the mount
  • Put the coupler back onto the shaft.
  • Drill the 1/4" hole thru the coupler and rod, using the mark you made to make sure the rod is inside the coupler the proper amount.
  • The hole should be 3/8" away from the edge of the coupler.
  • Drill thru both at the same time. You will need some sort of vice to hold it down while you drill.
  • Double check that your bolt will fit thru. If not, either re-drill it with a slightly bigger bit, or do another set of holes.

Step #4: Weld the shaft to the hammer

  • Remove the coupler
  • Fully weld the hammer to the shaft, plug-welding the back side, and welding around the shaft on the other side.
  • Make sure this weld is SOLID.
