Extremely In Depth S&G 6730 Wheelpack/Wheel Float Analysis
Hello all,
I am deeply analysing the wheel pack geometry and wheel float phenomenon in my Sargent and Greenleaf 6730. I have attached an indicator which I am using to read the movement of the lever at drop in with different wheel positions. This first graph shows both wheels 1 and 2 at their gates at L50 with wheel three AL one increment at a time. This gives an extremely accurate measurement of the geometry of wheel three and it's effect on fence movement. Now I will be doing wheel three AR, and then wheels one and two AL and AR each. This is obviously quite time consuming but is extremely interesting and valuable data in my opinion if one wants to really understand how the lock works and the phenomenons that are sometimes seen while indicating the wheels via contact points. One observation that I have already made is how small of changes are actually detectable via contact point readings. Total movement of the indicator everywhere other than the gate was only about .003 but yet significant contact point readings can be found when graphing the wheel traditionally. I expected more movement of the indicator while graphing than I saw. Have a look and let me know what you think. More graphs coming up!
