"Heavy Duty BT-50 Centering Rings Uses Other Than...."
champfluff
I have used these centering rings for centering BT-20's in BT-50's, but they can be used for engine blocks for 24mm D, or E motors. Single ring for D motors and double rings for E motors will be sufficient, if epoxy is used instead of wood glue.

 
"Perfect for making engine mounts"
skorotky
Makes two engine mounts that fit in BT-50 tubes. Very nice quality.

 
"Fine centering ring"
andrew359
not much to say about centering rings, except that these fit and work like expected. I always seem to be short these when building.
