Bill,
 
Thanks, for your thought. I thought about extending the wheel base but there is 
very little space between the rear wheel of the pony truck and the front driver 
that I might solve one problem and create another. I think filing the inside of 
the cylinder is the way I'll proceed...I rather have a good running loco than 
one that looks good but doesn't run well!!  I doubt that anyone will notice 
where I removed the metal anyway once it painted.
 
Thanks

Hi Ed --

I have one of these engines (doesn’t pull well, but it runs nicely, as you 
say). I don’t have curves this sharp so I don’t have this problem, but 
here are a couple of possible solutions:

A bit of Scotch magic tape on the cylinder where the rubbing occurs. This 
is easily replaceable, and will probably last quite a while. (Only works 
if everything stays on the track in its present form.)

Remake the truck extending the wheel base just a bit. This would require 
sectioning the truck frame and adding a “doubler” over the joint where the 
two pieces were spaced apart. I went just the other way with a lead truck 
on a 4-6-0 when I was a kid, taking a piece out of the frame to shorten the 
truck.

This last fix is kind of being in the same ball park as cutting a clearance 
notch in the cylinders – it does nothing to improve the engine or the value 
of it except to make it useable for you. To me, that is an acceptable 
trade.

Have fun!

-----------------------------

I am having a problem with the rear pony truck wheel shorting out against 
the inside of the steam cylinders (front inside edge of the cylinders) on my 
42" curves. If anyone has run into this problem and has come up with a 
solution, please share with me what it takes to eliminate this problem. I 
could remove a small amount of brass on the inside of the cylinder but would 
like this to be a last resort solution only. This engine really runs very 
well otherwise!.

Thanks
Ed Sauers
