Sorry Si

Oil works! Works on catenary wire also.

I guess that I just cussed out the electoprotons and scared the bejabbers out of them.

Shove THAT up your nuclei !!

I don't (yet) have eneough track length to worry about wheel cleaning so I cannot argue against the catenary/&for track "oilers" but Si is totally correct re: the insulating properties of oil. Oil can also encourage micro organism growth over the long term; all oils eventually oxidise, thicken & entrap dust, bacteria etc. to form a grungy sludge.

John (oztrainz) : I've never seen a graphite stick like that used by Prof K in the video. Does it have any other (Brit friendly) trade names that you know of please ?

Reg: I'm glad you've fixed a very frustrating problem.

Regards, Michael

Atlas, Bachmann, Peco, and USA Trains all have lubricants that are Conductive compatible.

Thanks Nathan, that's interesting.
Perhaps based on a mix of oil+graphite ?

Hi Michael,
have a look at https://www.amazon.co.uk/KOH-I-NOOR-Progresso-Woodless-Graphite-Pencil/dp/B00H8Z2WS8/ref=pd_lpo_229_tr_img_3/252-2133528-8009713?_encoding=UTF8&psc=1&refRID=SWKQW3P3D3880WC8D7M2

These are the ones that I use. These have a plastic sleeve around the graphite. Just one of these pencils is a lifetime supply, so you can afford to give one to a mate or two.

I find the 2B and 4B give best results but the others are also very effective. The trick is to notch the end of the pencil and hold the pencil at an angle so that you can apply graphite to the top and inner (gauge) face as you swipe it along the top of the rail. A light to firm pressure is all that is needed. The aim of the game is to leave "a smear" of graphite along the top of the rails, not to grind the graphite and rails through the baseboard. ;)

Glad it works now, conductivity problems are the worst!

Yep ! :f:

Hi Michael :wave:

I haven't seen the Profs. video...
...BUT !
If you search on eBay for the 'Koh-I-Noor' brand...
...they make SUPER BIG artists clutch-pencils, amongst other things.
Quite nice kit !

They sell 6-packs of 1/4"ish & other sizes, refill sticks, El Cheapo !
They also make VERY CHUNKY and soft/dark, graphite hand-held sticks as well.
Up to Grade 6B I seem to recall.

This is also a good alternative for coupler-pockets, to the Kadee product 'Grease Em'.
Sand a bit orf on some emery & BOB IS YOUR UNCLE ! as they say in China !

:moose:

Si.

Thanks, guys, for all the advice. What started out in frustration has ended in an entertaining, and informative, little thread.

I am going shopping for the Koh-I-Noor pencils. Sounds like the ticket to me.

I also need to rig up an easy way to clean wheels. Back in HO days I used a cradle I made from a chunk of wooden gutter and some soft fabric.

Try finding wooden gutter. I don't remember what kind of fabric I used except it was soft and had some give to it. My locos were all diesels then, too.

I think I might work up some kind of cradle using packing foam. It would be easiest if I could lay the loco completely on its back.

In the latest round I just laid the loco on its side on a couple of pieces of 1/4" square spruce. Doable, but awkward and risky to detail and paint.

One note of interest...I was under the impression that for the consolidations and the ten-wheeler the tender trucks contributed to electrical pickup. They certainly have electrical contacts.

But, apparently, not so. No matter what I did I couldn't get any action using the tender wheels and the drivers. I had to make all contact through the drivers.

Thanks to John & Si; something else to go on my shopping list.

Reg: are you referring to Badman's consolidations ? Mine certainly pick up via the tender, as do the MMI K's. Are your tender to loco wire connections & plugs/sockets OK ?

Regards, Michael

The railroad is now entirely operational. Well, almost. A critical switch machine decided to pack it in.

I will be interested to take it apart and figure out the failure point. But I have an idea. Switch Master has you solder the actuating arm (you really need to go their web site to understand how this works) to the output shaft. The output shaft, which carries some plastic gears inside the case, is steel. It takes a lot of heat to get solder to flow on steel. I did the first two switch machines according to the instructions, but all subsequent machines I attached the arm to the shaft with JB Weld. The machine that failed is the very first one installed.

I stopped in at the Elma Variety Store (which is an institution around here, if they don't have it, it probably doesn't exist) to look for graphite pencils.

Sure enough, they had a set. It consists of two fine point wood pencils, three woodless pencils, and three graphite sticks.

I adopted the 2B stick as my main applicator. But I also took the 2B woodless pencil and narrowed the point down so it would fit between the switch points and stock rails. I cleaned all the points and applied a bit of graphite to the points and stock rails to preserve that path.

Only time will tell for sure, but, at this point, the graphite pencils are the ticket. Locos are running better than they ever have.

Now I just need to replace a switch machine.

Off to the Switch Master web site after I complete my Administrator duties.
