Re: Blackstone K-27


I think from what I have been told that was the problem with the Bachmann Sepectrum Shay and Climax series, the gears were of the same material and wore out after about 45 minutes of use.

Yes is the short answer. Apart from ensuring that the worm's pitch is correct you should use dissimilar materials for worm and gear. If they are both the same they will wear quickly. I'm not sure what BS gears are made of but they look'Nylonish' using the original brass one would prevent any such problem.
