[QUOTE="Marcus Bowden, post: 96929, member: 3287"] Patrick Godet is running plain B/Ends I'm about to venture in that direction with an "A" Comet as it has a much greater loading area and an oil p/p of much greater capacity, although not much pressure as it p/ps to an open roller system. The gear type "A" scavenge p/p is 1/4" wide and supply is 1/8" wide, uring on the side of caution I've in-creased the supply by half as much again by machining 1/16" deeper and making gears to suit. The floating bush idea Royal Enfield used for years as they just had grooved center and radial holes to outer faces, I have made additional herring bone design grooves to with in 2 mm from the edge of the bush, other wise pressure is lost. Tremendous saving in cost too, just grind old pin precision grind rod eye and make bush to suit £20 for a nice bit of bronze ,couple of days work with whole lot of job satisfaction, 9 months I waited for my last B/End to be dunned. bananaman.
