Low Cost DIY Rod Weighing Setup
OK, reproduced your jig as best as I could using a bearing instead of the 3rd pointed thingy. My pan looks to be about as thick as yours, no deflection at all under weight. I F'd with this thing for 10 minutes then moved the entire thing to the very level concrete floor of the garage. WOW, what a different. It was looking alot better on the rigid surface as I didnt have that chunk of metal you had as a base. Il upload a video of all the drama, kinda boring if your not into this stuff but just goes to show you what the most minute positional changes can do to these scales. funny thing is this scale is incredibly repeatable when you lay something on it, but these loads off a fulcrum really send it to ****. Under the big end center is a small hole that the bearing sits in so as to eliminate any side load and distance variation. Pardon the upside down video, dont know how to rotate it.
