Marriage: Causing the reuse of irons since 1974.
Sidenote: We can use your old irons to practice porting on. The RB template is very conservative and there's some more that can be removed
. I just need to find out how much more by abusing your bunk irons.

Even still I think the rennie comes with pre-balanced parts so you just need to get matching rotors and you should be fine. not 100% sure on that though.

From what we could tell there was no uneven wear. We need to get a dial indicator and fab up a mount to perform the proper tests. the bearing wear did not appear to effect the shaft.
Also let me remind you that someone on these boards pieced together a motor without balancing and it ran fine for 50k.

Its not needed! Unless you change out something in the rotating assembly (e shaft, rotors, flywheel with no counterweight, etc). Or unless you are planning on keeping it pegged at 9k for the life of the engine.

There is no clarity... Its a rotary hahaha. Everyone has an idea of how things should be done, including myself.
Time to trail blaze sir.
As for the dial indicator, I borrowed one from a shop when I did mine since you don't need it till the build is complete.

Pineapple told me balancing is a must and IIRC he uses another shop for that. I believe BDC has the tools to do this right? Let's roll up there. I'll text Tito and see what his expert opinion is (besides, "your loco man, put a 20B in it")
