Show Simple Plan to Replace a Coupling and Magneto A simple way of replacing a coupling and magneto when the taper Is worn Is to true up the taper by using the compound rest on a lathe (not by moving the tailstock). Set the compound com-pound rest so that It will turn the new taper as shown In the Illustration. rtw Ttfti r 1 I 1 .CMUOf m COMPOUND K5T If rr 1 J TnC HC f bOTn --y iool ifvrrco .. 11 Fl The Taper on a Magneto Coupling May Be Easily Trued Up by Setting It in a Lathe. After the taper has been turned on the magneto shaft, do not move the compound rest, but leave It at that setting. Put on the chuck, and turn up a new flange coupling, finishing It all but the taper. Then turn the boring tool upside down and run the lathe the same way as before, the tool cutting cut-ting at the back instead of tlie front, the taper must be the same und the coupling will then fit perfectly.
