McCulloch Chain Saws

[MS460WOODCHUCK]

Hmm .... I dunno if a governor will even fit. Biggest I've ever seen is a state senator.

Seriously John, I've never seen a 'governing' device in a PM700 carb. Can you post a pic?

The only reason I was asking is because my pm700 screams a very high rpm and will still 4-stroke a little. Made me wonder about it. I don't want to run it too lean.

Another crap shoot at the chainsaw shop everytime I get a chain the teeth are different. This grind I havn't seen before but it throws chips like a woodchipper. I believe it's square grind but havn't seen this particular grind.

Those are fast cutting. I use a couple of those chains. I just can't sharpen them.

 

[Mac 6-10]

That is square ground. The fastest cutting but the hardest to sharpen properly.

 

[ethar]

How exactly do you sharpen these use to the old chains. I'm assuming it takes a special file and patience.

 

[heimannm]

Square grind done correctly is fast indeed, just not a good choice for cutting dirty wood.

It takes a very special skill to sharpen one either by hand or on a machine.

Good news is they can be filed or ground with a regular round file or chain grinder to be "round ground chisel" and still work very effectively.

It is interesting that they have square chisel on hand and don't recognize the difference. Perhaps you need to check with some other shops...

It can be filed free hand but you need a steady hand and good eyes, plus the goofy files needed and a solid mount for the chain while filing.

You can also set up a Granberg type filing rig for square chisel, the top angle is more like a ripping chain at 15 or 20°. Do some searching and you will find a number of threads that go into great detail on square filing.

On the cutter it's marked as 20. If it stays sharp with what I cut I'll get it again. Hopefully it will last a month but since I don't have a file to touch it up we'll have to see.

 

[heimannm]

Most chains won't last a full day of cutting under normal conditions, you should plan to either learn how to file the square chain, or jus file it round so you can keep going. I will either touch up a chain with a file, or change it for a fresh one after a couple of tanks of fuel.

Usually I have to touch up a chain at least twice but most of what I cut is fallen trees so alot of grit in the bark. If a chain will last a month without some serious filing I'm doing good. In the last month went through 2 chains 3 axe handles and 2 sledge hammer handles. With the axe the handles shatter on me guess I'm hitting it with too much force or could just be the cheap handles I'm using. Got 4 or 5 chains that need to go to the shop as hand fileing aren't going to fix the cutters.

Interesting acquisition from e-bay

I will try to get it transcribed so you can all enjoy the lyrics even if you can't hear the tune.

The things you find on ebay. The one thing I need to find I can't find but am finding everything else.

Got a call to help cut a cedar today. The PM 850 made a good showing. The next best saw there was a husky 455.

Did manage to get a replaceable rim system for the 1-46 off of ebay for less than $10. I like those better than the spur type clutch bell.

Sometimes pics are not enough.

Looks like the tree was split. Is that why it was cut down? going to mill it and make some cedar chests?

 

[joeymt33]

It was hollow and they were in fear of it falling. There is some there that can be milled. I plan on going back and getting it.

 

[ethar]

Cedar is good for all sorts of things used a few small rounds for gate posts. Depends on the cedar but alot of mills will give you good money for logs.

 

[Mac 6-10]

Some mills will give you 12-15 cents a board foot out here for cedar but most cedars out here are 4-6" at the base and on fence lines. no mills out here will take any lumber near a fence line for obvious reasons.
