Lobbocks.
Your bands should be good quality and matched to the manifold (I use AGIR bands as they are the widest and as good as the Highland Mills which I believe are no longer made).
Once your bands are on these are what are holding your cylinders in place.
If your bands are cheap and cheerful then yes there is the possibility of movement but it's remote.
When you shift your cylinders around you'll never get both cylinders grounding at the same time so saying your stressing the manifold by having different height cylinders also applies to having cylinders that are the same height....unless you've calibrated arms so that they lower the cylinders perfectly every time. |
Putting twins together, best to have them lying flat on a bench, attach the manifold and have the bands sitting losely around the cylinders, once you have torqued the valves, then start tightening the bands, this way you have light or no pressure on the manifold, plus, if the tanks are slightly off height wise, the tension isnt on the valves, the bands once tightened will take the majority of the strain. With 12's, you may find between Lux or Faber around 4/5mm off, with boots on, this is hard to notice.
