Right On Ralph! I"ll be doing the removable / adjustable tip plates to facilitate removal and adjustment during experimentation. I'm
using two mounting screws on the end ribplate, the forward one being a "pivot point" & the rear screw will lock the tip plate in position. The tip plate will be slotted in the rear mounting hole so as to be swivelable up and down. Has anyone noticed any improvment in knife edge performance due to increased side area after adding tip plates of sufficient dimensions?
Hi BalsaBum; A slot will weaken the plates and maybe cause a whistle. My adjustable ones had three holes, one mounted the plate to be flush with the top of the wing (all plate area below the wing), one was in the center, and one caused the plate to be flush with the bottom of the wing (all plate area above the wing). I don't suppose you could tell the difference in any finer adjustments.
I just screwed on the approximate shape in the upper hole and then marked the plate to match the top of the wing. Then moved it to the lower hole and marked the bottom to match the underside of the tip rib. When you cut it out you have the perfect shape for an adjustable tipplet.
