However if its near a riveted seem or staybolt I heat yhe stud red hot and let it cool off, no quench. You can also put some kroal on it when worm and wait for it to work . Say 10 min. or so. Most of the time that will work. bb |

Isn't "the axle in effect is the armature shaft" what the Milwaukee Road "Bi-Polar" and some other locos of that earlier era used? The "Quill" is a hollow cylinder with the axle running through it. Prongs (quills?) on the ends of it engage spring cushioned "cups" inserted into the driving wheels. The motor armature can, but does not have to, use the "quill" as its core. Wasn't the advantage of the GG1 that it used 12 small motors, possibly like the ones in PRR MU cars? Each pair turned gears mounted on a hollow quill (12 motors, 6 driven axles). Is it possible that the competing R1 (4-8-4), only one of which was built because "Old Rivets" tested better, was the electric loco with the large motors that you mentioned? > SD90MAC to power an NJT cab car???? DEFINITELY APPLES AND ORANGES. < But probably possible, as many modern diesels are backwards compatable for many generations. Thanks for expaining about your loco's transformer. Now, when will your "Little Joe" be running? TyburnRR@cs.com |

Impressive new cog engines, I think in Switzerland. http://abpr.railfan.net/abprphoto.cgi?june03/06-14-03/BRB_1.jpg ryarger@rypn.org |
