I'm seriously considering converting my soon to be purchased L-32/Zippyy joysticks for top-fire - however - I don't have the equipment to drill the proper holes into the ball-tops (I only have hand-tools).
I'm looking for someone who has done this before, has the equipment and can do the drilling of the tops for me - the assembly I can handle.
PM me and we'll discuss how best to do it.
Be seeing you,
WonderAlex
