Will begin the project to convert my 3A from original steel disc to 60 spoke wires once the new tires and 1/4" spacers arrive (end of week, fingers crossed). Can't seem to find what the torque specs are for the new nuts holding on the wire wheel hub. Does one exist?

I've been using 60 ft lbs on the spline extension nuts for many years and never had one come loose.

Although the nuts are high tensile, they only have a narrow spanner contact area. An old trick is to keep a dedicated socket for that job with the front chamfer ground off. It then gets full purchase across the width of the hex faces.

"Practical Hints" gives 60-65 ftlb. Page 51 in the 6th edition.
