While adjusting the R/C I just installed on my K-28 I noticed something I can't identify.

Please excuse the technical lingo, but here is a thingy on the right side of my K-28 that is some sort of adjustment with a long threaded rod and a nut holding a spring. The rod goes through a fat tube and terminates with a curved gizmo at the top of the reversing mechanism doohickey. What is it called? What does it adjust? Dave? Jason? Got any ideas? Right now the spring has no compression and the nut is loose, but it doesn't seem to affect anything that I can see or hear.

Is it merely a replication of something on the prototype that has no function on the model?

I think on the prototype it would have been a 'counterbalance' spring for the reverser. If I'm thinking right, it would have helped when putting the engine in reverse, instead of just lifting the dead weight of the links it would have helped push them up. If that's right, it wouldn't really be needed on the model and is just there for looks.

All of the K-28's except 476 had power reversers that moved the long Johnson bar linkage. The detail you mention is the modeling of this feature. It is also on my Accucraft #476 but will removed when I get around to it. I specifically wanted #476 since I've got video of the engineer on the D&SNGRR using his foot to push on the non-power assisted Johnson bar on that loco.

Well I guess since I have 476 alao I should remove it to be proper!!




and add an articulated engineer to the cab with his foot on the Johnson bar!

Just my thoughts, It looks nothing like a power reverser. I think Justin is right it is a spring assist for the reverser, not a power reverse. I do not know if 476 had one though.

Carl, I loved your description of the Whazzit. It made me smile and laugh out loud. /DesktopModules/NTForums/themes/mls/emoticons/w00t.gif It reminded me of when I would sail my 30 footer and on purpose call halyards, sheets, boom vangs, downhauls and the like, completly incorrect terms. After 20 years of haze gray and underway, I figured if I was the skipper of my own boat, I could call 'em what ever I wanted. I remember getting into a long discussion with a guy over the difference between rope and line (as if it really mattered!) When I was active duty all that was called small stuff anyhow.

It's your K, call it a Schnitzengrüben if you want! :D
