stew i silver soldered the spokes in the center hub, them turned the o.d. to a light press and used 620 locktite into the bore.had to make the spokes twice as i had trouble getting them to solder, opened the holes up .003 and then pickled it all for a couple of days in vinegar . then used a larger tip to get the right heat, second time a charm. hope to get more done this week, need to cut the radius on the two parts.i also need to get some fire brick to help in silver soldering.jonesie
