Reply To: Bachmann Class 20 Conversion (2021 version)

This is an incredibly useful post for me as I purchased an Ultrascale conversion set a year ago, and have been looking for an older version Bachmann Class 20 to convert on the secondhand stalls at shows without any luck.

I took a chance yesterday and bought a later tooled version of the model that was on offer at the Ally Pally show which has the later bogie design shown in your original post – so I have same conundrum with old style Ultrascale conversion set vs updated bogie design.

I’m up for doing the same conversion that you have done and purely by chance I happen to have the same blue puller set as you (great Amazon find!!), so I should have all of the parts and tools to do the job!

A couple of questions that I do have….

Did you reuse the original Bachmann axles complete with gears, or did you carefully pull off the gears and fit them to the Ultrascale axles?

Secondly, when you filed back the spacing spigots, how much overall float on the wheel set was needed to ensure good running?

Thanks in advance
