Quoted from v8torino:
Went for it full tilt....pardon the pun !! ) Marked and scribed the lower ramp fork and took my Dremel tool and routed out that area of the playfield clear coat and down into the wood of the playfield so the ramp now sets all the way flush !!! Filed down the sharp leading edges as you did and then polished the ramp with Scotchbrite before re-installing---pics later or if anybody wants to see them LMK - Kirk
Picture Please, and Thank You.
