@Norton posted:I believe it was Bob2 back in the original Niagara gear thread who pointed out the best Delrin gears are cut, not molded and that NWSL plastic gears were cut. Stock Drive Parts offered a Delrin gear in the same sizes as the Lionel gear that was also cut but it turned out the SDP gears are a straight cut spur gear vs the helical gear Lionel uses. The helix is very subtle though and only obvious when placed next to the spur gear.

I stand corrected, ....I wouldn’t have thought a nylon gear would be cut in the same fashion a brass gear would be.......but then again, I’ve always avoided a nylon or any plastic gear like it’s got the plaque......and I own a couple with plastic gears.....🤢🤮
