Thanks very much Peter, that is excellent.............Just need to decide if we go stainless or cad plated steel. I'm leaning towards the plated steel just like all the other small steel items back then, excluding a black parkerised finish. I will get some machined up and go from there. Plus the threads will probably be 1 BA I have never seen a perch with 1/4 BSF threads, and I have quite a large collection of handlebar levers and perches. Not saying that they weren't that size, only I don't have any........Let me know if any of you need of want a different thread, or other ideas's for same. Cheers...............Greg.
