My concern with using a water based dye is whether the water will cause the tie to swell making it out-of-scale? Or is that assumption unfounded?
One other question regarding hand laid rail. I've seen in the videos where a jig is used to space the ties. That is all well and good with tangent (ie straight) track. How about curved tack? Won't the ends of the ties on the inside of the curve have to be spaces closer together than the ends on the outside of the curve? Are there any methods of methodically spacing ties for curves, or do you simply eyeball their placement?
