Milling with an 051

[Mr Chainsaw]

So this is my first thread, I just started milling. I read the milling 101 thread but, I need it in better words for my dad. I've already got my chain at 5 degrees and my rakers down.
So I've been milling with my 051 lately and my dad thought it was kind of slow, so today I pulled out my 038 magnum and made 1 cut with that. It outcut the 051 3 to 1. It was also using standard chain, so my question to you is does the chain speed make the difference or will the way the chain is sharpened make the difference.

It wouldn't surprise me if the log is small, like less than say 16". The 051 should do better than the 038 in large logs if all things are equal.

Might be the angle on the chain. 5 deg will give you a smoother cut but you're cutting endgrain - much tougher than crosscutting. How far down are the rakers? Taking a bigger bite will slow it down as well.

 

[Mr Chainsaw]

Ok, so for a rougher cut but faster speed, keep it at 35 deg. And for a smoother cut, but slower speed(a lot slower), I keep the chain at 5 deg.

I forgot too, that the 038 is using full comp, while the 051 is using full skip.

What is the diameter of the log you are doing the cutting?

If it's a small log then chain speed will win out.

When you say the rakers are down , down to what.
If you want a chain diagnosis post a magnified fully side on photo of a cutter and I'll give you some feedback.

Bobl has had some very good threads on chain for milling over the years. He is a expert at csm. If you get a chance take a picture and post it up. In fact really try to do it because there has been a lot of pictures lost from the big crash. Time to rebuild the information threads and get some pictures up.

Sure ill post some photos later today, any feedback would be appreciated.

 

[Mr Chainsaw]

Well now, how do I post a picture?

 

[BobL]

Start a reply by clicking on "More options" rather than "Reply".
A text box will open up and one of the 3 choices you can make underneath is "Upload a file"
Follow that trail and you can post a picture.

 

[Mr Chainsaw]

This is my chain on the 051, at 5 degrees.

Thanks for posting the picture. It's bit too far "out of focus" to make a reliable comment.
The edge of the cutter looks rounded in the pic - see if you can take a sharper picture - maybe in daylight.
The raker depth seems OK but the gullet looks like it could do with a serious clean out.
The top plate cutting angle (cutter hook( is hard to measure but I measured it as best as I could and I get around 65º which is way too high.
Compare your cutter with the following.The top cutter is CSM guru, Will Mallof's cutter, the one underneath is one of mine.
If you are milling softwoods you could afford to go a bit less (i.e. more hook)

 

[Mr Chainsaw]

Oh now I see, that is so true. I'll look my chain over again, thanks for that.

As stated, chain speed will win in small logs but torque is king once you get into some bigger diameter. In 16" elm my 440 would walk all over my 075 but in the 30" elm the 075 won by 2:1. I sharpen my milling chains exactly like I sharpen my cutting chains with the exception on the 10 degree angle for milling. I really need to look more into sharpening my milling chains like Bob suggests and see if I can get more chips and less dust.

A couple of other things to look at on an old saw are the condition of the fuel filter and the air filter. My fuel filter looked clean but it was disintegrating and clogging itself.

That 051 sucks a lot of air and needs a clean filter or the RPMs will drop like a rock. Try cleaning the air filter.

One last thing that could be causing a loss of cutting speed is a bad rev limiter in the carb. You can still by these from a dealer, or you can cut a tiny circle from a soda can and put it underneath the limiter valve which will disable it.

possible the most likely reason the 038II out cut the 051 is low compression in the 051.
