Might be good to start a new thread for your build. I'm sure it'll get a lot of interest.
Would you care to share the strain gauge you ordered?Ordered a strain gauge and amplifier to mess with as well. Should get enhanced accuracy wrt force measurement that way. Will need to figure out a calibration lol
Will orient the torque arm vertical so no weight error. Cal will be a known weight at a precise distance.
That was my first sketch and my final product was changed many ways. I read pump shaft rpmsChad, looking at your general arrangement sketch, it hit me that your tach is engine rpms? So do you reduce that in your formula by the 7:24 gearing? Iirc that is your sprocket setup?
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.Pad and pencil works lol
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 spreadsheetHow about video recording?
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.
It appears that friction/stiction is the enemy of my hydraulic load sensor
It is repeatable but it takes extra force to overcome the oring stiction. Will try a different seal to see if that can be corrected
