See post # 110 ........... there was a loup "POP" when my head was pulled from my arse, and everything was clearer after the Molson XXX wore off. Nice examples !
lol. I missed that.

I found the 24 tooth sprocket in a company from Washington state. I found a cutterless chain onlineGreat job putting talk into reality, then publishing your reality for others!
That's 2 steps more than most take and 1 more than many people do once they put the work in. I think it looks great
I read through this entire post and I can't find the answer to a simple question I had.. where on earth do you get a 24 tooth chainsaw sprocket? What did you use for chain? (grind the cutters off?)

Here is the company I got the 24 tooth sprocket from Sprocket Applications
Not sure if I can ask this but here goes. Would anybody be interested in a dyno if the cost was $1500. Maybe I could make them cheaper on the next build. I'm just trying to figure out if this would be worth manufacturing.
Well I'm now working on getting it dialed in. I got some vibration dampening pads for the scales to sit on and a new scales on the way to compare the two. I'm reworking the hoses for less drag. I'm using my stock 461 as the mule.I've been thinking about this thing since I first read it and have an idea for a way to verify the readings.
Use an electric motor you have laying around, any motor of any size, and use a volt meter and amp meter to record the wattage used when loading the motor to its full potential. Wattage can be easily converted to HP with a simple calculation. Compare your wattage input to your dynos recorded power absorbtion and you will then know your correction factor. Try this when your fluid is cold and hot and you may be able to interpolate and graph a correction chart based in fluid temperature. I would think it would be a linear function. Then forget the rest and keep it simple. As most who have worked with a dyno know, it is about proving repeatable results and recording changes, not the final numbers. So if you start out with a baseline reading of a saw then record power improvements after each mod and can repeat the results you would therefore have a scientifically proven method of data acquisition.
An individual could also use a spare saw as a "mule engine" one that is never touch or changed. A mule engine is used to make the first couple of runs each time a dyni is used. Those runs are compared to the previous mule engine runs, and a correction factor is derived from the difference in results. Allowing an individual to compensate for changes in testing conditions that may have occurred over a couple weeks or months between tests.
I'd haul this to a gtg if one were close by. I would let anyone run and tune there saws on it.My gut take on this is...
It'll be a darn handy thing to have in the shop for all the reasons mentioned
around tuning motors and keeping notes on 'em.
hmmm, how many adapters can you rig for checking the [local ?] lawn mower racer's engines etc ??
2nd: I'd wager this thing will be a big hit at the first few GTG's
*IF* you have the opportunity/time etc to carry it around...
I'd love to make my first trip to a GTG and see the first "dyno races"
...could make for some interesting "tuning clinics" and so on.
Ahh I have other ideas,
but as always more ideas will lead to more new variables to have differing opinions on.
