So that means you'll have a new video up shortly with a better chain and better tuning on the saw, right?

Yes! Get and use some GOOD chaps! Here's me getting slapped by a chain off my 046. Just a ported work saw with a pipe, 9 pin sprocket. It cut into my chaps and stung a bit. The last cookie dropped onto the bar and threw the chain.

Yowser. That was a close one!

Yup, close enough for me. The chain had stopped rotating when it hit me, it left 3 small cuts in the chaps where the cutters hit. Just a slap.
Sounds like me, lol!

Hey Trout....
I think you should post this vid as a separate post to get everyone's attention. It really communicates how unexpectedly a minor slip-up can happen and the safety edge that chaps give. I know it has convinced me to start wearing my chaps...

Once guys starts playing with piped saws, especially the big alky-nitro saws and bike saws, safety gear is a MUST. I won't even start the things without chaps on. Watch the chain in this video, it gets thrown completely out of the rails, and the chain was tight. I've fixed the problem, but I was just lucky it was staying on.

Had a chain come off an 026 cutting square cants at a gtg, just came in too flat on the log, chain came up off chaps and just kissed knuckles on my right hand enough to make them leak a little.

What do you do for work?
How about we take this a step farther. If this doesn't fit in this thread, just say so and I'll move it.
What would be good porting numbers for a piped 460 or 660 work saw/GTG toy? I've heard mention of only 160*-180* of exhaust duration. I'm guessing 160* would be too little for a work saw and might even require blocking the top of the exhaust port. I don't want to take it that far. No two-piece head here either. I'm talking about numbers to put into a OEM cylinder to work well with a pipe, and still be able to do some work with. I know there will be some compromises here from the outset.

Right on! A diesel Mechanic! That's cool bro... Makes it a bit easier on ya to work on two strokes then, being as you already turn a wrench.
Why did you get laid off?

all info relevant to piped saws, and me learning more about them is ok by me!
I want to re-port my 460 for a pipe, but will probably leave the pipe building to a pro. I have virtually no experience working with metal like that. I would like to do the porting myself though, just for the satisfaction factor. I have to admit, I'm in love with the pipe Timberwolf built for that 361. I especially like how it wraps around to the right side, tucked in close to the saw and out of the way of the operator. This saw currently has close to stock port timing numbers with only the intake lowered a couple of degrees. I'll have to get a degree wheel back on it to know where I really am. Both the intake and exhaust are already widened to their max. The transfers have been widened and tapered towards the intake. The transver intakes have been blended all the way to the bottom of the jug. The windows in the piston have been worked over considerably as well. Basically, I just need good port timing numbers that will work good on a pipe: intake, exhaust, and transfers.

our build has dropped 75%. we have permanantly laid off 550ish people already and who are left are dealing with temporary layoffs. as our schedule sets right now, I am only working 12 more weeks the rest of the year!
