That's cool! Are you climbing higher up the hill.of.mid-power Rocketry?
Yep, I'm building more MPR rockets. I've never stopped with the LPR stuff, but I like the big stuff too, and this is a beauty.
As far as I know the current versions of the NCR kits all use standard 29mm mounts.Does this kit have a regular 29mm motor mount? If I recall, old NCR kits had an odd 28.5mm MMT that would just barely fit a SU motor.

I really love this kit (I'm a sucker for strakes) and it got used a lot for Chute Release testing on H and I motors.
Two mods:
1. I built it as "nose cone separation" rocket, rather than mid-body separation as designed.
Why? Less worry about stability (not that it has issues), and more room for Chute Release + bigger parachutes...
2. Added an Estes 29mm plastic motor retainer. I put those on all of my 29mm rockets.

A few thoughts on the video:
1) Very nicely done!
2) Did you think to weigh the tube before and after? I would guess you haven't added enough weight to affect anything, but curious anyway.
3) This effort really shouldn't be necessary. It's so much easier to sand out a tight centering ring, not quite sure why NCR doesn't just size the rings a bit smaller and eliminate the need for this sort of thing.
But again, very nicely done, you made the process seem pretty simple and straightforward. The first time I heard of someone rolling their own tubes I thought it was insane, but it's really not so bad I guess, as long as you have an appropriate mandrel.
