Thanks for the replies,
Musky - that is a great article which doesn't encourage the ring-ping test. Until now I didn't know you could buy a torque wrench for spokes. Definitely on my next Christmas shopping list. (I wish I had posted this a few weeks ago). Seems I might also acquire a Wheel Balancer as well.
For both tools, there is a huge range out there on the Internet.
The comments on the BSA straight pull are spot on. I had no trouble. The CL90 - I had to unlace it a second time before I got that one right. They are all hooked spokes.
On all wheels I have done, I clamped the wheel spindle in the vice, but with the vice rotated 90 degrees, the wheel would not clear the bench, so I did them at an angle.
The Lilac was a dream. All 4 spoke types ( two per wheel) are identical and straight pull.
Just for fun, I have attached a couple of shots of my Lilac. I hope the moderator doesn't chuck me off.!
Once again, all my questions answered.
