Spent a couple hours fabricating the mounts for the dynamo. I am using 4130 steel for these brackets as well as a piece of 1/4" aluminum. I mounted the lower end of the dynamo with a bar of 1/4" aluminum bolted to 2 of the lower right case bolts. This is the pivot point for the dynamo. The upper end is the swinging end and is mounted via a 4130 square tube with a notch cut in it at one end. This end goes to the dynamo and allows the dynamo to swing in and out for belt tension adjustment. The end of the bracket that bolts to the cylinder head has a 1/2" 4130 tube/spool welded to it. I had to do this to locate the square tube about 1.2" away from the cylinder head. I did not want to just run a spacer because I felt that the bolt in the cylinder head may shear. I figure the welded spool method displaces a great deal of load at the base where it meets the cylinder head and would also provide for good shear resistance for the bolt. Only testing will prove whether this mounting method will succeed. More info on the dynamo can be found at Mark Langford's website. click here
The pics show it fairly clearly. |
