Another chainsaw dyno...

[Red97]

Well been holding out.

Finally got tired of cutting wood.

Wanted to share my new tool with the class.

First few runs after getting everything all calibrated.

This has a built in weather station, to keep track of temp/humidity.

Those are the sae corrected numbers. Very close to the 660 book specs.

Last week's project making the "bench" and jackshaft.

This is a 30hp rated waterbrake, 17k rpm

Have A 2:1 reduction. Helps smooth out the runs with low tq saws.

Adjustable power head rest with a thick rubber cushion.



Designed it to work with Any power head I could think of. Even raise up enough for belly pipes.

If it can run a std 3/8×7 rim I can run it on the dyno.

Thoughts?

Wow Joe. I’m impressed.

 

[jacob j.]

That's awesome Joe. I'll have to send you a Mac 125 to see how it does.

Yessir.

Made the mount the big stihl 14mm slot. With the small stihl tail profile.

Everything has to run a 3/8×7 to keep my ratios correct.

But I did design it to hold the fattys...



116cc of echo. Can clamp it almost 45* while still keeping everything in line.

Twice in the same day.....


I remember those days

Any of my junk is available for benchmarking Joe. I'm an hourish away. All I have still stock is a 2171. Limiters still on the carb. If it helps. Or maybe I just want a beer and brat day watching Cole's saws. But seriously the Johnny is all stock...

 

[Bigmac]

Super cool! Test more saws!

Who likes dumping chips, and having to file chains anyway...
