Does anyone know where you can get a long sanding mandrel for polishing the ports? (Besides RB)

Also, I got my injectors back from RC Engineering, and apparently three were OK, while one was dripping. But now they all flow 'excellent'ly according to the data sheet, and are on spec (450 cc). Also, they look brand new now! Their cleaning process is impressive, to say the least.

I got my side irons back from being lapped, and all the damage and wear is gone now. Very nice...
