get together this weekend

Hi Ed, glad Paul made it there ok, twelve hrs. is a long drive. How's my 7900 coming along?
Dennis, I'm filing so true now that one of my 1.3 mil chains will run true in a 1.5 mil bar. LOL

 

[Dennis Cahoon]

Gypo, when you can get a 050 to run in a 063 let me know, because I have and still placed. Dennis

 

[ehp]

No Dennis a 18 tooth .404 is bigger than a 13 tooth 1/2, so lots of chain speed
but the chain doesnot jump up or lift out of the bar but i can tell you and no BS , this stuff do cut fast , it kind of surprized me because that is the first time filing that kind of chain , i thought it would cut but not that fast, in 15 inch wood it cuts as fast as you can drop the saw, it is waiting on you , not you waiting on it, we will cut some bigger wood soon

 

[glens]

The math correlates .404×18 with ½×14½, while .404×16 is almost exactly the same as ½×13.

 

[Dennis Cahoon]

Ed, this is a tooth of the 404 I'm playing with. I'm trying it on my Mac. Dennis

 

[jokers]

Nice pic Dennis, Thanks for putting it up. I think I can see a little of how you are thinning the kerf.

Russ

 

[Dennis Cahoon]

Jokers, that tooth is thinned from the inside to eliminate keef, but you can't tell in that picture. The outside of the tooth has been stoned and that's what your looking at. Dennis

 

[jokers]

Hi Dennis,

I recall how you had mentioned at an earlier time that you thin your teeth from the inside, so I assumed that had been done here as well. What I think I noticed is that you also surface grind or in some other manner thin the top of the drive link, the part normally covered by the tie straps and cutters. That in itself would narrow the kerf about .008 wouldn`t it?

[Dennis Cahoon]

Yeah, the driver is ground to 050 to make a 404 chain for the chainsaw motors. The bike motor chains will stay at 063. Dennis

 

[ehp]

Thanks Dennis for your info. , and who said you never put info on here, yes we are using .063 gauge on the bike saws, and it cuts very smooth about the same as 3/8's on a chainsaw,real nice, do you think your top plate angle is thin enough , mine is a little thinner

 

[Crofter]

Dennis;

It looks like you tigged up those rivets before grinding flush in last picture.

Frank

 

[Dennis Cahoon]

No, the tie-strap[tooth in this case] has the holes beveled so the rivet is mashed in good enough to grind the rivets flat on the strap.
Ed, thanks for the advise on the top angle, I'll try it and see how it works. Dennis

 

[ehp]

Dennis ,Gypo is coming up here tomorrow and if he beings his camera we will post a video of the rotax ok

 

[Dennis Cahoon]

Ed, would like to see the Rotax cut, but let Gypo just take videos. What ever became of the 250 you were making? Take a picture of that too. Dennis

 

[ehp]

No picture of the 250 , they will see it at the stihl series

 

[Gypo Logger]

Hi Dennis, what do you think of my new Rotax? LOL
