Now that the mast is back up I will have to tune it for the first time.
I have a Selden fractional rigged double spreader which seems the norm for Bavaria.
The fraction appears to be between 9/10 and 19/20.
The shrouds (cap and lower) have wire diameter of 7mm.
I have the Seldon Rigging guide but not much detail given on this particular fraction
The previous owner had the backstray really tight and it appeard not to have moved for years
I have a Loos Model B tension meter.
Any pointers or links from members who have tackled this job previously?
