    Not too much happening this weekend, still recovering from our trip; however, have "tweaked" some of the track work that has been laid and getting ready to finish the track work.

    Quieting down here too...

    ...just painting half the module sidewalls:


    ...and building a few more wireless throttles:


    Next week will be even quieter - I won't take a camera with me on the business trip, so any modeling I might be doing won't be documented

    Started the weekend with a really demoralizing discovery -- recently purchased an Intermountain F3A-B set from a hobby shop via ebay. Looks to be in great condition but listing says noisy. A-unit shell is hard to get off but B-unit shell comes off smoothly (those of you that repair lots of locos, especially older locos, may know where this is going). Turns out A-unit almost definitely has Zinc Pest.

    I searched around a bit (and even re-read an old thread I started here where someone commented on Intermountain locos being oft afflicted) and seems that a number of people with IMRC locos (F3 units in particular it seems) have encountered this. I hope I can get a new frame from IMRC (although their website says no parts orders for non-warranty repairs due to factory shutdown).

    I wish the modern instances of zinc-pest were documented better. Seems like a problem that will be around for a long time to come.

    So keep moving along this morning -- kids went to the gym so I decided to work on the other locos I got. Happy to get a few Katos running nice and quiet (they were squealing when I got them).

    Also found out that I could use a fiberglass pencil to remove errant paint and excess weathering (which is what this post is about).

    I originally bought the fiberglass pencil to help me remove stubborn paint from shells. However, I have mostly used it to clean really dirty contacts and commutators (which it works well for -- make sure to blast to whatever you are cleaning with contact cleaner so no little pieces of bristles get stuck in there).

    In this case one of my locos had little splatter marks all over the top of it. I tried soap and a little scrub brush but that did not take it off. I assume it was overspray of something diluted but may just be really stuck on grime. So took a chance and scrubbed the top of the cab with the fiberglass pencil and it worked like a charm to take off the marks. Pictures below.

    Also tried it to remove an errant paint mark and it also worked for this (be careful not to go all the way through the finish / factory paint). I was thinking you could also use to de-weather something that was a bit too weathered which I tried a bit but I rate this as "too early to tell" or likely "it depends".

    I had the zinc rot like you in two F7's. Print out the repair form and filled it out. Sent in the whole engine but the shells. Got word they where received and being repaired.I would do the same.
    Zinc rot should be warranty work, not caused by owner. Jim in Minnesota

    Agreed, especially if this is a known and constant problem.

    Mac: is a fiberglass scratch brush the same as a fiberglass pencil? What brand and type did you use?

    Sorry about that -- some of my pictures that included the tool did not show the spots very well and got cut when posting

    Not sure if it is the same thing or if I am using the wrong name -- did not realize that it was called a scratch brush. I just have a generic one that I got at a train show. I asked if they had fiberglass pencils and these were what they showed me. It looks like these:

    Uh, not almost definitely. That is definitely. Suddenly it's the 60s, and 70s all over again. How is it in this day, and age this is even still an issue? Totally unacceptable second hand or not.

    I made some progress on the last car for the Lark.


    Roof details on the 2-1-1 Observation:










    She's just about ready for the paint shop. I have to fill in the factory side markers and a bit more light sanding.


    Hope Y'all had a great weekend,

    Those are made China right? Same Chinese zinc rot as the lifelike engines from several years back, there is often minimal concern about what is used in manufacturing materials in China. Anyone heard of Kato engines having this issue? Kato is Japanese built.

    Between snagging a slow speed 5 pole motor for $12, a pair of newer Bachmann trucks for $12, and finding an EMD F series Spectrum chassis on ebay for a mere $2.50, I made the pleasant discovery that the old drive shafts still manage to fit inside my "new-old" rebuilt Bachmann Chessie System F9. I rolled it on tracks successfully for the first time since... Probably since 1997. Sure, the only thing original is the shell, and I misplaced the windshield (it's in ONE of these several dozen identical drawers...), but she rolled under her own power for the first time in two decades today! She pulled rolling stock today! I know it's just an old Bachmann I snagged for $7 in 1993 and rebuilt with under $30 in parts... But it's my first locomotive rolling again!!!

    Pretty much built the guts to a 2004-2012 series Bachmann Spectrum F7. The original guts were the 1983 revision of the Bachmann F9... The old guts were seized... Cracked axle gears. It also never had good pickup, and had a pair of traction tires. The new trucks are all darkened metal, and all pick up power... No traction tires.

    https://i.imgur.com/ArA59nt.gifv
    Look at those slow wheels!

    0925182321.jpg
    I'm noticing there is a small gap near the top... Maybe there is room for DCC to be fairly easily modded into it internally. My original plan was to get a second A unit to double the traction to the rails, and run a dummy B unit with big speakers and DCC+sound wired between the two A units... But if I actually got the room for a DCC board in this, maybe I can just stuff the speakers into the "dip" in the chassis, near the front of the B unit, and have the DCC board(s) wherever, but have all the units motorized. All I know, is modern units have room for a DCC board, and there's a gap on this one. I suspect that it's well within the realm of reason and a little machining.

    I wasn't even planning on doing anything train related today!
    I honestly put it all together while on the phone for an hour!

    To be fair... It's no different than tearing down and reassembling an engine to clean and lube it... You just use a different set of parts on the reassembly bit.

    I believe you, no question ... so, um, how do you tear down an engine to clean and lube it?

    Quick update before I go back home tomorrow for another crazy modeling weekend: Three general service, nine LPG and four ethanol tank cars got their new body mounted MTL couplers installed and their trucks and wheels reinstalled. 20 ethanol tank cars to go, though probably I can live with twelve total for the meeting next week. We'll see what else I need to get done, especially how my locos behave...

    Cheers,
