Step 12 Triple tree fork plate

The top of the triple tree fork is just a bit of plate or flat bar rounded at the edges to conform to the width of the fork legs (Photo 12). A hole is drilled at each end to approximately the center of each fork leg, or to allow a bolt to pass through the plate and meet a nut welded into each fork leg as will be shown in the next photo. You may want to weld the two nuts in place first, coming back to drill the holes in the plate later, just in case the two nuts are offset in the fork legs as the ones I used were.

If you really wanted the holes centered on the plate, the nuts would either have to be large enough to fit snugly in the fork tubing, or a washer would have to be welded in first, then the nuts into its center hole. The method I used here (using half inch nuts and bolts) works just fine, and is plenty strong for this design.
