    Great tool but you need room around the piece to be clamped to swing the tool around it. I am always on the look out for anything that will reduce my stock of spare parts and I think that tool might might help but not in all situations.

    Absolutely correct, and is the major limitation to the tool.
    Oh my, I have creeped a thread again. :-(

    Ummm... what do you mean not very adjustable?  It will make a wire clamp around any round or roundish object you can wrap wire around, from 5mm id fuel hose to, oh say, 200mm fence posts.  Larger than that if you make sure to take as much as possible of the slack out of the wire while attaching the tool.  I own a medium size one, and it will pull about 100 to 120mm of slack out of the wire while tightening the clamp.  I plan to use it to clamp on my mast coat, among other things.

    I've cut my battens to length and drilled a hole through each end and fitted 8mm eyebolts. I may have to plastic sleeve them to prevent corrosion between the two metals.

    Here's a tool that will beat a conventional hose clamp to death.  Standard disclaimer applies: I don't have any stake nor obtain any benefit if you buy one, but there's nothing like it for fastening to round things.  You can make a wire clamp, one strand, two, five strands - whatever you like - of any size that you can wrap a wire around, and make it as tight as you could possibly want.  You can use it to clamp fittings on hydraulic hoses.  It's an amazing tool.

    I ordered my battens today. 6 @ 6.6m x 44mm x 1.6mm...$297. They don't need to be that long but that's how they come. I should have them sometime next week.

    The 3 alloy battens on Footprints are of T5 alloy. From memory 63mm in diameter but only 1.5mm wall thickness. The theory being that by going up in diameter you gain strength. They are very lightweight. Because we can only get 5m lengths of alloy in NZ and my battens are 6.5m in length I preferred not to sleeve or weld the alloy so I used the cedar from my previous timber battens to make up the extra length. So far there has been no sign of bending and they seem to be as stiff as the other 4 carbon tube battens. I know though that I will need to be very careful about gybing in strong wind conditions.

    For my previous flat sail I was very happy with the cedar battens which were reinforced with a layer of unidirectional fiberglass on each side. At the time they seemed to be the best option cost wise and weight wise especially compared with alloy which once again I would have needed to sleeve because of the length requirement. Those cedar battens developed just the right amount of curvature in stronger winds. Normaly cedar would not be a suitable timber for battens but with the unidirectionals on either side it was OK and being cedar it is very light when compared with other timbers. I always thought it should be possible to engineer in a bit of bend in the timber battens by reducing the timber thickness at the point where the bend is required and with the unidirectional glass reinforcing the battens should still not break - but I was never brave enough to actually do it !

    Metaland price for T591 38.1x3.2 is $60.70 including GST. The price for the same size in T6 will no doubt reflect it's rarity.
    T5 44mm x 1.5mm at $30+ is looking better and better, despite it's inferiority.
