Cock on

Chris has got it cock on, the only way to do it is by using a membraine. Rendering it both sides WILL NOT sort out the damp problem, no mater how much waterproofer you use.

As a teenager I wanted a Sigma Wand, but I never got one. I'm definitely having one of these though. The new rod is cock-on!

what I do is mix a small amount of fast set epoxi resin glue and hold the screen in place with fingers or blue tac, wait for the glue to start going stiff beffor I put a small dab on each end of the back of screen to mod, this way the glue wont run or capillary attract across the front surface, when satisfied ive got it cock on center, I can then seal the whole screen against the mod using the same method.

One attempt, nearly there.... I gave up taking photos at this point but it took another two goes to get it 'cock-on'. Now tighten the three 13mm bolts so the outer cam pulley is locked back to the inner pulley.

Cock-on mate well done!

Cock on mate. These reports are a bit special
