I only have one pair of Ace RB freight trucks in active service on SHABBONA, although I have 3 sets on order from SMMW. I use just a drop of Mobil 1 synthetic motor oil to lubricate the journals, and they roll almost as free as some of the contemporary trucks on the market. I have for years tried to locate a source for the brass bearing inserts, thus far without success. I have used some delrin tubing, but I still prefer the integrity of the brass ones.
As for flanges "picking" frog points, another way to cure this is a few swipes with a modeler's file on the offending point. I have also ACC'ed an .010" strip of styrene on the back face of the guardrail to infintesimally increase the check gage with good results. As usual, I don't guarantee my track laying procedures to9 anybody foolish enough to try them, but my railroad is derailment free for the most part, in spite of them. boB Nicholson ____________________________________________ --- In [email protected], "pickycat95" <pickycat95@...> wrote: > > I have always liked the ACE trucks.
