Spacers a little complicated. It should be a snug (not tight) fit between the bearings.
In my experience the spacers that come with buddy flywheels are too small. I usually get them 2mm too large and then file them down a little bit at a time.
Most people don’t like the plastic spacers but I’ve found that they tend to perform better, but not for very long. I bout 20 sets of plastic spacers and speed rings off eBay for around 2 bucks, don’t remember exactly as it’s been a few months.
I lock my wheels down tight with these spacers. Because they have thicker walls than most skate spacers they provide a very solid setup and my wheels spin for a long time. The fit really depends on the particular wheels your using. If they wind up being a little big, then I just let the wheels float on them a little because it would be very difficult if not impossible to file or hand grind them down while keeping the mating surface flat and square. You would really need a lathe to trim them accurately.
I’m gonna order some of those spacers, prolly sweet.
BTW, the way you file them.is with a jig. I don’t have a pic, but it’s essentially a piece of 2x4 drilled to hold the spacer tight horizontally and th exact depth you want vertically. Set the 2x4 between to pieces of angle iron (which are clamped to a table top) with the file clamped underneath. Then you just run it back and forth until it stops sanding. I do 4 at a time usually.
Always openmindet for new stupid things (-;
