Is 19mm carbon fiber tube actually 19mm ?
I bought some and try to insert into this sliding plate with 19mm holes
and it seems like the 19mm tube is more than 19mm or the plate
opening is not 19mm.

so what's the standard on buying carbon fiber rod - do I go 1mm less ? or sand it down ?
 
Rod tolerances is a black art.

Different clamp companies don't adhere to anything.

Ideally 15mm would have a hole 15.05 to 15.1 and rod 14.9 to 14.95

Even anodising can mess with this.

If you bought something off the non camera shelf expect disaster - if you bought something from China expect disaster.

And carbon fibre dust is poisonous so don't polish it without knowledge of what you are doing.
