Ladies and gentlemen:
I want to know everybody's deepest and darkest thoughts on the subject of wheel wipers for electrical pickup.
Now, I have this view that they are a necessary evil. It's not their appearance that I mind but their lack of functionality, at least in my HO steam engines. The only ones I have that really work well are the pivoted shoes on a Mantua Booster, with a separate spring to hold them against the wheel tread, but this is quite a collection of parts, and doesn't fit in engines with smaller axle spacing.
What I want to find out is what design works the best. Is there any arrangement of pickup wiper that functions as well or almost as well as picking up current through the axle bearings?
I have used Rivarossis with wire wipers that hook over the flanges, Life-Like tank engines with plain metal strips, Model Power engines with wheel-back wipers, and none of them seem to work really well.
Cordially yours, Gerard P. President, the electrically incompetent Sparta Railroad.
