Let's talk race chain

My worked over chassis chain in Ethan's build-off was slower than the one with minimal work, pictured earlier in this thread.

Think the rakers could have used a swipe or two with a file.

Looks like they could be a tad lower. Tough though when you have never ran the saw it was going to be ran on.

Raker height was the biggest factor in that race.

Nah I heard you were squaring chains now. Could be wrong. Did you see the CL ad recently for some of that 50L south of AA?

South of AA......

that’s like...Ohio or something

Probably. If you're in AA. Lots of stuff legal there now to help you lose all sorts of bearings.

Yeah purely for work chains though. I doubt I'll have time for race chain/racing. Young kiddos have a way of gobbling up all your free time. Amiright @Armbru84

Ya...they can do that.

You need a fast saw first .
Did you get the 7900 ported.

That ain't no joke .

Can't see your emoji on this end bud.

Been playing around with filling an ive come up with this

Try thinning the rivets, I did this on my play chains and there is noticeable gain.
Please take note I did NOT write race chain.



Yeah, I know - it is just round filed.
It is a well used regular work chain that I played with a little.

Got it lol.
Funny how many guys post them on different platforms and sometimes you can see them, and other times you "cant", to get things back on track lol..

Did a little messing around on some scrap chain, to kind of get a feel for what I need to do. What do you guys think? As of now its filed round. Waiting on my files to try my hand at square filing. Just did the one cutter and the 2 connecting links.

My advice would be to start with the basics and what that will do, then add to what you learn, a lightly worked over chain done by someone who understands what they are doing will be faster than a way worked over chain by someone who doesn't. I don't know you so I'm saying all this based on the picture's you presented and what I've seen work, although I don't build race chains .
Start with a stock chain, time it in a lice long log or cant. Next square it up with mild angles, then time it again. Make the angle a bit more aggressive and then time it again. At that point you can adjust the rakers to the saw/wood or take the cutters back a little further if the rakers are a little low for the aggressiveness of the chain in that wood with that saw, or try an 8 pin sprocket.
Once you get a nice chain then you can do another one the same way except start with the cutter a bit further back(a bit in front of the rear rivet) and you can add the chassis work. The chassis work will add a very small bit to the speed of the chain in the beginning stages of your work.
It's good to understand what effects the chassis work or changes you are making to the cutter will make as they many work together and others can help make a chain faster without making other changes.

Notice what is said here .

As Chipper said you have to start with the basics. Know the wood your going to race in and start to test things. Key thing is consistency. Your chassis work looks good on the rivets and straps. That’s a very small pc...speed comes from the cutter.
