I have 4 locos that really need some more traction. So I got some Bullfrog Snot. I figure I would ask first before I mess up and have to do it again. Model are as follows: Model Power 4-6-2 semi-streamline Model Power 4-6-2 Pacific Bachmann 2-6-2 Prairie Bachmann 0-6-0 Switcher Seems like the rear drivers would be the right ones to apply the snot. But it never hurts to ask. Where should I put this stuff on each loco? Thanks. Dave
JMO... If its a loco that HAD a traction tire...put it in that grove. If its all wheel drive and all wheel pickup...I would do the middle axle. DONT put it on a driver that may be the only axle with pickup ! Just a small dab on the end of a wooden toothpick works wonders. Put the loco upside down in a foam cradle...apply power...slow speed...apply the SNOT. I usually snot close to the flange...but not on it. Once you have a nice bead going on both drivers...same axle...STOP !! Let it cure. People have said that SNOT actually works better then a traction tire ! I use the stuff on my smaller diesels that have a hard time pulling themselves let alone some cars. I have had great success with the stuf. YMMV...
Thanks George. None of the 4 locos I listed have traction tires. I have one other Model Power semi-streamline with traction tires on the rear drivers. That is why I figure the rear drivers would be best. At least on the 2 Model Power locos anyway. I just don't know about the Bachmanns. They are both newer Bachmanns with tender pickup. I am going to switch out the regular Bachmann tenders for the all wheel pickup spectrum tenders as well for improved performance. Dave
Yea...sometimes I think where a traction tire or SNOT goes depends a lot on aesthetics. When the loco goes past...the only driver you really get a decent look at is the front one and the rear one. Seeing a black traction tire...or dark green SNOT on the surface of the driver...may just bother some people. I cant think of any logical/mechanical reason for which wheel....other then not on a wheel that has electricl pickup to it...as the snot would most likely stop the continuity/connectivity...JMO...
i was told on the atlas board that the MP pacific's headlight gets it power from the front driver only. check out "model power pacific" over there if you like.....
For steamers, I generally apply on the crank main. For malleys, thats two axles If an existing tire is in place, I remove it and replace with BULLFROG SNOT. Multiple layers, allowing each to fully cure before applying the next, until I reach the desired level. Eliminates the wobbles. Diesel power trucks will rock due to torque effect. So the application can seem 'directional'. For a A-B lashup, I apply BULLFROG SNOT on opposite ends - just one axle per loco. Not on the central wheel of a C-C BULLFROG SNOT gets scuffed with use and the green virtually disappears. It can be 'freshened' using something like a Trix wire brush style wheel cleaner. But, if you don't like where you've put it, just scribe it and peel off. BULLFROG SNOT does not adhere, it shrink fits. For smaller steam, with poor pick-up to begin with, I've made a trailer car using B-mann or Kato side-wiper tender trucks under a boxcar. Hardwired to the motor with DCC wire. Makes 'scenery' engines useful. Bill
The Bachmann locos are done. I will test them after the snot cures. The 2 Model Power locos are giving me fits. They have brake detail that will not let the snot spread out and set. The details keep scraping the snot off. I may have to take these apart to install the snot. Anyone take a Model Power pacific apart? How hard are they to work with?
