[QUOTE="Oldhaven, post: 55411, member: 2879"] Hi Vincent, It seems everyone who has fitted a hydraulic damper to the Bramptons finds it a big improvement. Unfortunately I am still a couple of weeks from my first outing on my B project using the Thornton modification. (and your brakes). Others who have used it are very satisfied. As I mentioned in a previous post, this does require some fabrication of mounting clevises. I would not worry about the original Brampton fork parts, especially the top mount, since it is designed for the spring already. The bottom Thornton mount is on the Brampton spindle housing, and was intended for the headlight stays. This seems rather chancy in theory, but other users have had no problems, and it is strengthened since it is tied to the bottom spring claw by a small gusset. With your capabilities, I think you could manufacture a bottom mount that would be similar to others I have seen that fit both the headlight stay mount and the claw, and possibly providing another place to mount the stays that does not slightly pivot with the damper. If you do that, make one for me.... (I bet when Michael Breeding gets his complete Bramptons finished, he will sell quite a few of them, as they are undoubtedly a lot stronger than the 65 year old originals.) As to color, you have a point, but if disassembled the aluminum parts could be black anodized. I kind of like the aluminum finish. I notice your speedometer seems to sit a bit more horizontal than mine. Different bracket maybe? Ron [/QUOTE]
