On the 181 and flat filtered 288 , metal gas tank . The air was pulled from the back. On the plastic tank, stack filtered 288 there is a slot formed in the left side bottom of the top cover. That was pre Air Flow system. That feature made it so we didn't have to make a hole/ slot there. As we...
I've worked with a lot of guys that cut on St Helen's. They had different techniques the used to deal with chains getting dull quickly. Some guys ran 084scso they could PUSH HARD when their chain got dull. . Some would fall as much as they could without crossing themselves up. Change their...
Tho I'm of the opinion that a razor sharp chain properly jointed on a good straight, true bar is 10× more important than what powerhead is pulling that chain. As far as it making a cut goes anyway. The fact is that just a good consistent chain on a good bar will get the work done. This...
Depending on what is being cut. But generally daily or every.other day. . When.bucking a blow down patch, getting in the grit is the single most frequent means of the chain getting dull.
Try as I might it happens more than I wish.it would. . And throwing a chain takes its toll also.
Life...
Chisel grinder is almost infinitely adjustable. And more adjustable than a chisel file. With a chisel grinder, the tooth can be lightly buffed, polished or ground to correct shape and sharpness. And all the teeth can easily be done the same. Long bars full of wood will show that cutter...
:lol:
Magnus, the Silvey Pro Sharp, SDM 4 and Simington 451 . A,B +C are all more adjustable than a chisel file and more repeatable. The burr can be consistently eliminated by giving the top angle of the stone a light buff dress and not feeding the tooth into the stone too fast.
Now your gettin it Jed!! Nothin ventured, nothing gained. . The more you.do it the better your results will be. Imo, chisel fileing is 30% head knowledge 40% eye hand coordination/ experience. And 30% good files and fileing set up.
Then kinda pick your battles. If you rock the snot out...
Yup, squared up it will cut smoother and be easier to control in the cut.
Ideally you would use a Silvey Bar Rail grinder. . However a less expensive solution is to put a 7" metal cutting abrasive blade onto a 10" portable table saw. . Use a square to make sure its at 90° and use that
I've...
Jed ; if your chain can tilt 10° when the chain is properly tensioned. You have a wore out situation goin on. You can try rolling the rails then grind the rails flat. Shouldn't have to take too much off. Just get them flat, parralel and true. When you roll the rails, make sure you have a...
Other than the magnifying glass on my head I don't use one to check and see how sharp my chains are. I used my scale/paycheck. . And what parts of me were the most beat up exhausted at the end of the day, week, month and season/year. . But Magnus is right. This thread isn't a pissing match...
Liked.
And the previous post by Jay.
In fact LOTS of excellent posts on here. . Including several by Magnus.
I don't want to go on a roll here so I'll just say that if your cutting softwood and your not taking your riders down at all until the cutters are half gone, well your chain...
A sharp chain isn't exactly the same as a good cutting chain. But any good cutting chain needs to be sharp. !
But for me, a sharp and good cutting chain is one that cuts the fastest with the least amount of effort on my saw handling. Meaning I don't have to pull like I'm in a tug o war or...
Since dull, wore out files are half the problem with guys hand fileing. Some of them think a file should last as long as a chain does.I'm gonna give the cider vinegar a try.
Really true!! Getting someone to get every tooth the same is ime the hardest part. Then they can improve 1 part at a time and get consistent at it. Pretty soon they have all the parts consistent and they have reliable cutting chains.
The extra work of chisel fileing may not be worth it for many situations. Like Holmen said long bars and clean wood. Or. A long bar on a small saw. . I always ran 20" bars on my 242 , 44 Husky, 024+026/260 Stihls and chisel filed or ground my chains. It really maxized the small fast...
Maybe there were 2 dots over the O. Don't remember. I think Madsen's still carries them. They were the single best quality chisel bit files available. . Lasted 3 times as long as Valhalla chisel bit files.
When I started chisel grinding it took me a couple years to get as good grinding as...
For an, in the woods touch up file I like the Oberg double end file the best. !!!!
On the jig I prefer the 3 corner chisel bit file. . But being older now I just grind them.
