Cambium Savers

[Rich Rule]

They look good.

 

You do know though that the CE tag is for the rope construction and not your splices.

 

Unless you’re a certified splicer.

 

Out of interest, how long have you been in the industry?  You seem very keen, I very much doubt you will use all these things you’re making.

Dont throw metal weights around peoples gardens.At best you will break roof tiles and pavers,at worst you will hit someone in the head.

Why wouldnt I use them? Everything so far has been used when it suits. I currently set a sling and carabiner at my high anchor point for working in the tree, so the short one will replace that to be retrievable. The long one only for large old limbs, which we have done a few of recently.

Mike, the weight is for isolating, not for throwing.

I used to make all sorts of kit.  I spliced up an extra long cambium saver for a large crane dismantle of a London plane in Blackheath, London.

 

I barely used it afterwards as I soon moved onto SRT climbing.

 

I have a bag full of bits that never get used.

 

I guess it is better to have them and not need them than need them and not have them.

The multisaver is a brilliant bit of kit, on small trees you set it long when dropping away from the anchor so your rope isn't rubbing on the stem and shorten it up when you go back up.

 Chogging a pole you lengthen it as the pole gets fatter, or round lumps, then you have a descendable drt anchor all the way down which is safer than just throwing climb line round. Put the rope through the third ring first, stops it hanging down and getting spiked.

 

So a well thought through, reliable, safe bit of kit. Works well, retrieves well, passes loler. Much better value in my opinion than eg ART ropeguide at over £200.

 

I haven't used my fixed length cambium saver once since buying it, definitely wouldn't waste money on one. Once you get used to a multisaver you can't go back, the fixed one is always too long or too short and hence a pain in the arse. As you say, wrapping ends your chance of retrieval, forget it.

 

I wouldn't hesitate to buy another.

 

Edit: forgot to say Stein make a version now as well.

 

I have never had my ropeguide stuck, my friend has had his mutisaver stuck a number of times. I used to use a ring to ring cambium save, I was blown away by the difference in friction between the two. 

 

As for cinch up when up close and longer for further away that too can be achieved with the rope guide. 

 

Minehead is due replacement, will be wincing when that one gets ordered but it is a brilliant piece of kit!

Been using the first two savers quite a lot! I had a birch job recently, I was doing a few hours, every other day, I left the savers up but pulled the ropes through with throwline, they were up nearly two weeks.

 

Inspected them after and noticed some coarse abrasion on the alu rings, no problem on the steel rings. I cant remeber what way around they hung, whether that was from dirty rope abrasion or running on the tree. Marking is not on the inside face of the rings, which makes me think tree. However the abrasion is up and down, makes me think rope.

Rope is soaking in the bath to get any grit and dirt out.

I'll give it a fine polish and rotate the rings so the ropes not touching it. 

 

Any ideas on the cause?

Weird. It's got to be the rope surely? Nothing normally in a tree would be hard enough to scratch aluminium like that. Plus the direction of the abrasion as you say. That being the case I'd be concerned about your rope. If there's enough grit in it to cause that. Make it a long and agitated bath. 

 

Unless it was the throw line. Seems unlikely as well. 

 

 

[kram]

Had a much closer look. These rings are very unusual for an aluminium product - they are chrome plated!

 

On the other side, the rope has polished some the chrome away, the line is quite visible

 

[sime42]

The plot thickens. I thought they didn't quite look like ally, but assumed it was just the photo.

Can't help but laugh. The OP is certain he can improve on industry standard kit, for less money, then complains when his own ideas aren't up to his standards.
