So top & bottom lines are same weight?
Yes and Andy is right it is easy but you need patience getting them all equal length. I did my first set a few weeks ago and Gary gave me a great tip.
Make up one line the desired length and use that as the master to check the length of the others against.
Don’t pull them tight to compare the length, you will never get equal tension on both lines.
With the lines staked at one end, go to the other end hold two lines together and let them hang under their own weight, look down the length and compare the bow then adjust until the lines bow equally.
Choose a calm day and allow yourself enough time to do a good job and it will be time well spent.
