My wife does not understand this, either. Especially the fact that there are more than ten, and several duplicates. Oh well. She has more than one necklace... more than one dress, and so forth.
yee haw the gender wars are alive and well


Yup and it doesn't help that we don't burn wood of that if I do get a "tree job" it's usually a bunch of over growth in someones yard lol.

Question about rakers. For high horse power can you lower the rackers more? Also when I speed up the saw the chain will not bite. It just bounces off the wood. This is a hydraulic saw using 404 semi chisel chain. 32 inch bar.

I'll ask Luke how he sharpens his on the processor. See if he does anything different.

You want about a 6 degree angle of engagement on the tooth.
For more positive feed, try a 50 degree tilt vs a 60 degree under the top plate.

Too much rpm and the teeth will not bite properly.
That motor should spin at half of chainsaw rpm or go to a much smaller sprocket

I will see if I can find some numbers on the motor when I get home to night. No documentation with the machine. Chain speed is to fast with the hydraulics in high flow mode.

Still going through it and getting everything adjusted the way I would like it to run. Was used to process 10 inch soft wet pine logs.

Yeah, I'm thinking no more than 4000 rpm or so. Although I've seen piped 3120's use a 12 pin and spin 14,000 or so.
Not semi chisel though.

I am following you on the 50º tilt. But, explain the "6º angle of engagement" you speak of. Are you referring to the top plate angle, which is usually 30-35º?

No, I mean the raker to cutter height difference.
As the length increases between raker and cutter, the height differential between the raker and cutter must increase incrementally to retain the "angle of engagement ".

It is a F11-010-HU-GV-K motor

It is rated at 9000 rpm continuous and 11000 rpm short term. So with a 3.75" diameter rim. The chain speed could be a high as 122 mph or 179.98 ft/sec or 2159.84 inch/sec. No wonder the chain skips off the wood. It does slow down once it starts cutting. As I said the previous own had it setup for speed.

That would do some damage if a rivet gave way piss reving

The Oregon 18HX chain does have thicker tie straps. H for hydraulic
