    Is the future of chainsaws battery powered?

    Not in my hands

    Major changes to Quadra Fire 5700

    Yes I have been using it. I use the air on the ash door to give the coals a little air up through the grate. I'm amazed at how much heat I can get from the coals now. I used to get four inches or more of coals mixed with ash that would not disappear easily and my house would be cooling down as I...

    Major changes to Quadra Fire 5700

    My Quadra Fire 5700 had a joke of an ash removal system. There's was a plate in the center that had to be removed then a lever on the side of the stove actuated a trap door that opened to the ash pan. I used it once. I fabricated a fully welded and sealed ash compartment with ash pan, sealed...

    Chainsaw Dyno rework finally complete and ready for some mod testing.

    No I have not. Tested a bunch of saws and then quit. The dyno has Been unused for a couple years now. I'd love to see someone put it to use. Somebody make me an offer.

    Chainsaw Dyno bring saws to there knees. Build from start to end with video

    Yeah I've done that too and that made it better but the scale and rpms took time to stabilize. Then I'd record all the info from my video and put it in a spreadsheet

    For a while. Pad and pencil take a time. Requires more run times to get the rpms exact and steady for recording the scale and rpms. To much time around a loaded smokey saw gave me headaches. Mostly because I was doing my testing indoors during winter months. I think a high tech data acquisition...

    The main reason my dyno sits is because I have failed to find a data acquisition system and software that fits my budget

    That was my first sketch and my final product was changed many ways. I read pump shaft rpms

    Would you care to share the strain gauge you ordered?

    Make sure to take pictures along the way.

    Best break in procedure??

    Use non synthetic oil. 40:1 Avoid high rpms with no load. Run it hard lugging the engine for a long cut of about 30 seconds or more then idle for a minute. repeat this a bunch of times. Pulling the engine hard pushes more pressure on top of the piston. The pressure slips past the piston and to...

    Oh and I mod bird feeders as well.

    I mod more than saws. This is my Kubota. Added a turbo and boosted the HP 76% Wait till the end of the video as I have some pictures of my fabrication work to fit the turbo under the hood. I'm looking into building a pulling tractor. If only I could get a turbo on a saw.

    Don't forget that two stroke saws do not make much torque. You need to measure ft-lbs in at least the .01 lb to be able to see the tiniest increase in HP. My scales measured .001 lb.
