I also made all the fasteners for this bike, including the front wheel spindle, pipe unions, etc, but unlike when I made them for my Manx, I felt that because the bike was not a completely standard Inter, I had some license to use modern materials. I made the wheel nuts, bevel housing gland nuts, and some other items in HE30 aluminium alloy to help keep the weight down, but everything else was made in Type 303 Stainless Steel. The shape of the bolt heads was different on the featherbed Manxes, with a larger size hexagon which was shallower, and faced off flat.
