As someone who has quite a lot of both, I wouldn't recommend it. It's likely to result in a vehicle which won't run properly. In uncompensated axles it can result in wheelsets which won't rotate, or which have no sideplay, and thus, if both axles are so afflicted, no tolerance at all for minor irregularities in the track.

Agreed if you take it to extremes, but it isn't as critical as it is with a sprung system. I didn't want to over complicate my answer.

As there appears to be a stone wall preventing resolution of the bearing/axleguard compatibility issues, I'll go back to my main point which was to use the plastic axleguards, slotted, in order to save a lot of work replacing them and adding castings. What's wrong with that then?


Absolutely nothing - it's what I do.

Agreed
