Spoke Calculator for unequal spoke numbers by Roval hub side

[bduc61]

Hi

I have made up a crazy plan : build a set of wheels with roval vintage hub and spokes but modern rims :roll:

I am trying to locate a spoke length calculator that allows to enter spoke numbers for each side of a hub

As I am trying to build a set of wheels on vintage Roval Hubs and the rear side is 16/8 spokes right/left crossed once for the drive side and radial for the left

each calculator I have seen asks for total number of spokes !

so I believe it must divide by two the total number of spokes to allocate to each side

and if I put the correct total number of spokes ( so the interval for each hole is correct at the rim ) it probably assess that there is only 12 spokes on the right; so the space between the holes is wrong on the hub flange
and if I put 32 to have the correct 16 spokes on the flange, it is the interval on the rim which is wrong !

Not to speak about the issue of how a Roval spoke length is defined as there is no "elbow" at the head :shock:
and that the lengths available of Roval spokes is very limited and generally too long as the spoke threading was inside the rim and there was a specific washer and nipple and the nipple was not protrudind outside the wheel - but that's another issue

Any clue appreciated

2:1 lacing pattern then radial NDS? If so just put 0x in the calculator and use the number for the NDS only. For the DS I believe 48 spoke 5x works I have yet to try it though. there is thread on weight weenies in which another possibly more accurate method was provided. Lost the link though you'll have to search.
