Anyone use these?

It's called an allistec rob d sells them their designed for detecting metel in timber for milling. I think the depth is 8" but I think it picks up deeper depending on the size of the piece

I would think stuff up to 25/30" diameter you would pick up just about everything in the tree useing the detector running it right round the tree

On larger stuff it's just going to reduce the risk

All in I think it's well worth it to reduce hitting metal saving chains and time sharpening. It's not cheap I think it was about £160 but it pays for itself in a year or so

I'm always finding metal in the area I work in so it's well worth it

 

Nice one thanks for that......Not that RobD again!!!!!

I use these:

It files the teeth and rakers at the same time so it cuts down the strokes by up to 50%.

Plus you get perfect depth every time. The round files don't rotate in the holder so I fimd that these last a lot longer too.

I usually always prefer the hand file, unless the chain is that gone that it needs the grinder.

 

It was just one of hose jobs where it was getting dark quick and the lumps needed cutting. Hand filing was too slow, so was hinting about a 12 volt grinder as the chains where knackerd anyway and got binned after the job.

have you concidered keeping a spare chain and just swap them, and shapen it later,

Yep. We had a spare chain but couldn't find it for the 088. And we had run out of .404 on the reel for it. Had spare chains for the others but it made no difference at all. It was one of those jobs that every cut at the start hit metal. And it wasn't the average nail either. They where burried deep and about 3/4 inch thick.

 

The owner of tree did day there was a tree house in it when he was a kid. THe metal detector didn't really pick much up. (Probably density of timber)

 

Anyway it's been put down to experience.

I use the wheel version Link I find you have to be careful you dont take too much off.

That's good. Shame One of the wall mounted ones are in the workshop

 

Not much good when an hour away from the workshop tho.

They're useless. A fresh file cuts quicker. The stones wear unevenly or glaze up leading to even worse performance.

 

If the chain takes a heavy knock and you only have files, simply restore the top plate angle with a FLAT file, then bore down and in with a suitable round file to get the required hook.
