Here are a few photos, some of which are in the video.

wrench shares this board as well):
Really crappy mid-experiment photo of the 2855 Gen 3 impact wrench’s electronics assembly (notice the different trigger, which is the only reason why I didn’t simply swap the driver’s entire assembly, as it wouldn’t be housed securely in handle moldings):

This modification was super easy, 3 wires to desolder/resolder. Can even be cheap with eBay finds…the 2953 doesn’t really even need to work. Feel free to ask questions, offer suggestions, etc. I am not an EE or a motor expert, just someone with some curiosity and the desire to hotrod everything
This was simply a “f&$@ it, let’s try it” procedure right before officially calling it quits on the experiment. It’s far from perfect, but it’s a step towards making this embarrassing tool what it should’ve been from the factory. Milwaukee would rather sell you more impacts, which is why I believe they corked this thing from inception…but hey, businesses have to do business things I guess.
My next steps are going to be looking into tweaking the impacting mechanism to allow it to fully reset with the anvil dogs upon every 180* rotation as intended. I’m not going to rule out sourcing a beefier spring…somehow? haha…but my first round of efforts will look at preloading the existing spring with shims. I don’t know, I haven’t taken any of it apart yet to know if it’s possible, but it’s a logical starting point.
