Throw saw

[andy_engelsk]

Any one else spot this diamond yet?

Its Swedish forester who has taken a broken saw chain, tied it into a throw line and is marketing it as a breakthrough technology. I saw it in a Danish lanpscaping magazine and he had a 3 page write up about how it is perfect for arborists!!
Its intresting idea but i wont be rushing to write him a cheque.

I've seen similar products, I just can't imagine it working that well? Too dull, you work your tail off, too sharp, you can't pull it through - IMO.

marketed to homeowners I would think.

I've thought about using one for dropping tops out that I don't want to do from in the tree, such as having to rig off a weak spar with no alternative TIP.

Face cut. Downwardly slanting back cut (for alignment from the ground) started just to have an aligned backcut kerf. Install throw saw into back cut kerf with long rope to reach ground. Lower out. Finish backcut and catch on block.

Haven't bought and tried yet, but kinda wish I had one for large cedars next week. No alternative TIP, decay in base. 100'.

Nothing new at all.

they have been around a long time. I would not use one

Old idea. I'd call it a rope saw. I have one. It tends to get stuck.

 

[southsoundtree]

there is some type of abrasive cable saw that I wondered about using for the sketchy top-drops. Anyone use one of those?

 

[treebing]

you have to stand under the limb your cutting

This is what I was thinking. Note the mullets on the crew. They were going to be helmets... a Hel-mul-et.

I suspect that it wouldn't work perfectly, but wondering if anyone has tried this set-up. Perhaps cut some of the holding wood from the sides, leaving either a hinge with triangular holding wood (as suggested for heavy leaners in Berenek's FGTW) or a sorta Coos Bay-ish strip of holding wood for the cable saw to cut.

Again this would be for catching a top on a compromised trunk where the climber would not have an alternative TIP, so would descend to a more solid TIP or the ground.

Bing is right your standing right under where the load is going to fall. You better be a fast running.

I use one everyday. They make perfect collar cuts.

I figured that one person on each side of the drop zone working together would work, again only in the very rare situations.

I wouldn't stand in the dropzone.

I had a by-the-hour customer one time that was a bit upset that I wouldn't use his throw saw and use the run like hell and hope method.

Set the 'chain' saw over the limb.

Attach a bungee cord or two to one end of the 'saw' and pull the other end. The bungees will pull the saw back.

Say...doesn't this sound like one of Red Green's solutions???
