@@matthewknight5641 After talking with a few people, we think the ring broke first and caused the cascade of events. Definitely a good learning experience.
@@dubbssawshop I'm just getting into building saws. I've worked on them off and on for a long time but recently started porting shaving some off the cylinder. Do you still like your Dyno Jo mandrels? I'd like to cut squish but I'd really like to cut it at an angle and cut a dome in the piston to match the chamber. I figure that would be taking weight off the piston and also the smaller distance from the ring to top of piston should let my exhaust out a little easier. And I think it might even help with getting air into the cylinder as well . Do you think the Dyno joe mandrel could be made to cut squish at an angle rather than flat?
I was thinking about cutting me an old piston to the angle I'll be using. Then glueing some sand paper to the top. Using it to cut squish then pealing off the sand paper and seeing if it would run good like I'm thinking. It might just be a waste of time but I really think it might be the way to go rather than cutting a flat band in the top
@@matthewknight5641 each squish shape has different run characteristics, tapered squish bands are great, just don't thin the top of the piston to much, leave about .100" of meat above the ring to prevent it from breaking. 👍🏻 go for it man, may tags a bit of sanding, but it can be done.
@@dubbssawshop im gonna try it and see how it goes . I think I'm gonna get me a dyno joe cutter here soon and I believe that's gonna help me alot with my builds. I got Aaron Lynch to build me a 460 lite and I'm excited about getting it. It's in the mail already. I can't wait to see how other porters set them up to make them so strong.
@@Houseworksaws there's a very small knick on the floor, it may have just been enough. The groove above the exhaust port was odd to me. Looks like the ring dug a ditch a few degrees above the exhaust roof. Saw probably had 5 tanks on it. And we ran it hard at Smitty's I figured that's when it would've popped 😂😂 but nope it waited til about the 5th cut today.
@@dubbssawshopRight lol who the hell knows what actually happens at 13-14-15k rpm lol 😆 all sorts of stuff goes on real quick. You’ll make it better and better. No sweat
I think you’re right Matt the bottom is more app to snag most people don’t pay attention to the shape of the bottom of the port, which is typically fairly flat if you widen the port and leave sharp corners on the bottom, it will most definitely snag.
This why I don't like using aftermarket cylinders and pistons, I bought a new hyway 52 mm kit for my 372 and did nothing to the cylinder bolted it onade four cuts after break in and broke the piston and top ring ? I call ryon at Wolf Creek and he sent me another cylinder kit no question asked but I sent it to a well known porter and he ported it put it on my saw and ran it until it popped so it's OEM for me
@@alltherpmthis one was a cheap $25 FT cylinder kit so my hopes weren't to high, it was a test build for SawFest. The oem build is going back on for the race just a bit sooner now 😆
Glad to see you have aa backup plan ready to go.
Well good thing it was the farmertec cylinder. Good thing you have the oem! Have to see it back like it was!
@@tedneitzel that's right!!! 15k rpm here we come. 😁😁
Bummer, I know the feeling.
Definitely not a failure in my book. Just testing the limits and seeing what didn't work... And could have just been a defective piston or ring too.

Bummer dude!
@@jamiewykes8585 it happens, sucks for sure, but we will get it back rockin'
They usually always catch on the floor of the exhaust from my experience. Most people think roof but on the down stroke they grab the floor.
@@Houseworksaws there's a very small knick on the floor, it may have just been enough. The groove above the exhaust port was odd to me.

The floor makes sense to me, the ring catching on the way down seems like it would chunk the piston above it like that.

@@larrywarner9314 yea the FT kits have a very flat exhaust floor and roof. Makes good power but can bite you in the end.
👍👍 was that the cylinder at Smittys? That was a runner!
@@crazyfeller5704 sure was!!! I never would have thought this one would snag after all the blitz runs. Crazy
@@crazyfeller5704 but with a small amount of exhaust clean up, and a good piston, she'll be golden to live again.
You will have it going in no time
If your not breaking eggs your not cooking hard enuff
@@CharlesBrisco you got that right buddy!!! Congrats on 30K 👏 👏
I have a video with the same title maybe it’s a curse
@@steelcityperformancesaws oh man that sucks!! Must be a good time for blowing up
Sux being this close to SawFest but if I know you you’ll get’r done.
@@Houseworksaws luckily I kept the oem P&C, it's already ported up too 👍🏻 just gotta toss it on and she'll be back in action.
I no couple hrs to me is not worth unreliable power!!

@dubbssawshop is there big Gaines in port widing?, maybe try to take some tension off ring?
👍🆙👽
😬🤐
@@Doc-Cole_Trickle-of-Chainsaws gotta send em high sometimes!!!!
@@dubbssawshopGlad it was the FT cylinder
@@Doc-Cole_Trickle-of-Chainsaws no doubt about that. 😁
