Thank you Patrice for the excellent pictures! What you see in many of the pictures is a replacement mainspring, (exactly like the original in every respect!) in it's combination shipping containment retainer, which also doubles as an installation tool?.. Patrice is correct in that the worst is taking the darn things apart!?....
..... Once you have placed the replacement spring assembly in the drum cup, you simply pry the retainer off from the relief hole and slot on opposite sides... then install the center pivot and wind the mainspring until the anchor hole in the spring automatically engages the anchor stud... then reassemble and preload to the correct tension, and Walla! you're back in the drum business....
... That is how they will come if you order a replacement! Otherwise, it's like wrestling a ninja cat!!!
.... BTW, More new revelations coming soon on the Numrich replacement drum tune up! Lots to tell, just not quite at the point to where I can tell it...
..... I will say this, in the past couple of months, member Don Voigt has been my "right hand man!" in any and all improvements made! As he has tested my repairs, (and some of his own!) to compare results and plan the next move / improvement.. We are almost there, and more info will follow when we have completed our testing / tuning procedures...
... Thanks again Don & Patrice, and as always, best to all, til...lat'r....GT.....
