Just another junk chainsaw

Unfortunately, the red line in the photo hides the detail making it hard to see the "bumper" is on a separate link.

The depth gauge aka raker is not the same on the LPX and LGX cutters as mentioned. Look at both. They are totally different shapes on the cutters themselves.

I dont really notice any difference in how depth gauges are shaped.

But certainly notice a difference with low-kickback chain like the LPX....like when plunge cutting.

That second tip or bumper or whatever you feel like calling it, is NOT a depth gauge. And in "theory" only comes into play as the chain passes over the nose of the bar.....due to its different pivot points allowing it to kick up HIGHER than the cutting tooth and prevent cutting/kickback at the bar tip.

This is a pretty good illustration

I sure wished I knew someone I could give Dad's (rip) chainsaws to. I'm sure they're not worth anything, all Craftsman from 70s-90s, some he took apart. Free..but someone would have to pick up. South central Virginia.
I hate to throw things away.

Talking only about the cutter with the raker in the front only.

NOT talking about the little lpx bumper you keep bringing up. Just the raker on the cutters are totally different. So simple to see that.

I wish they would use the LPX cutter and raker design on the new 325 LGX chassis. Be back to old school chains again.

What I see is the LPX raker is narrower and easier to file down with one swipe, I also see they both have oil holes in drive links and thats more important to me, other then which one stays sharper longer, then Stihl chain wins.......

Bingo. :thumbsup:


Thats how we used to make the newer chains cutters for race chains on the rakers. To get them like that on the LPX cutters.
