Video Rotatech vs Leading brand

[lewisyounger16]

I've looked all over and I can't find what kind of steel they use. I also can't find what kind of steel Oregon, Ozaki or Stihl use.I could be cutting this wood with something totally unsuited for the job and not know about it. I'd also like to know what kind of aluminium Husqvarna makes their pistons from and what rubber is used for the diaphragms in Walbro carbs.

I am not going to sleep over Christmas now thanks to you

But if you're awake santa won't visit you!

Still can't make my mind up on these chains. I run 3/8 on my 550xp. I tried the smaller chains when they were piranha on my 021 and found them very grabby and vibrated a lot. I ended up binning them. I find the 3/8 almost too aggressive as if I had already filed the rakers down. They are ok for logging, but hard to control at lower revs if you want to tickle a hinge or the like.

Saws aren't supposed to be used at lower revs, flat out is the way to go especially when "tickling a hinge" type maneuvers are being done. Any chain will grab if it's not up to speed.

Never had a problem using oregon or stihl chains at lower revs.

Doesn't make it good practise though.

I use them on a few saws 60cc and above they seem fine, I'm trying an 18 inch bar on a 560 but it seems to be getting a lot of built up heat at the tip after only an hour cutting even though its getting plenty oil, time will tell as I bought them as an experiment so the jury is still out.

Don't think I will use these again and will keep the second chain that came as an emergency back up only. I have found they run the bar hotter and are wearing the rails down by the nose sprocket at quite a rate. I now need a new rim sprocket because the chain has really eaten into it. The bar was new and the sprocket only had light marks on it when I installed the chain. At just over half worn there are bits breaking off from the drive links and depth gauges. Shame, because the cutters do seem to hold sharp longer than other chains, but they do seem to be made from a harder metal which I think is brittle. Just my opinion and observations, back to oregon for me.
