Old AHM/Rivarossi 4-4-0 upgrading

[gna]

The loco was then makeshift wired, assembled an analogue test runnings were made again. Note the replaced pilot wheels, the 33' wheels and the disappearing of the tender abdomen improving the impression of the model too. The flanges of the drivers were turned down to meet NMRA Standards.

I'm curious how you turned down the flanges. I have an old AHM/Rivarossi Big Boy I recently purchased, and I have been remotoring, installing a decoder, and tuning it up. The flanges are huge, pizza cutters, so it will only run on code 100 track.

Here's a few pictures of the remotor job. I suppose I should have taken pictures and started a thread but I didn't think of it:
