Hi all, an update on the sourcing questions below: For the paper drag springs, I ended up just fashioning some replacements from some .002 steel shim stock (easy enough; just some 1/2? x 3? strips with holes.) For the bushing and rings, these have the right dimensions and look very close to the original parts: http://www.vibrationmounts.com/RFQ/VM07003.htm I?ll probably order some of these up to replace the decaying mounts for the carriage assembly. I ended up just using some inexpensive 3/8? chassis grommets for the more straightforward end stop bumpers. For the grease, which is called out for the carriage loading cams and a couple of linkage pins/pivots, I opted for Molykote BR2 Plus, though I suppose any decent lithium grease would work okay here? Overall, I have been pretty amazed by the sheer number of machined parts, castings, high quality bearings, etc. within this beast. Lots of stainless steel throughout. Sure wouldn?t find anything built this way these days! What a tank. cheers, --FritzM.
