Blower massage

I have a Littlefield hi-helix retro 14:71 that has some scratches on the inside of the case toward the back, is there any way to repair them? Also, does anyone have any stripping material they want to get rid of as well as rotors for this thing?

 

the scratches on the inside of your case will not effect perf, but are more cosmetic, but if you do want to fix them, the case can be coated by companies such as H.P.C. then the O.D. of the rotor has to be fitted with the bore size of the case, hope this helps. If you have anymore ?'s call me at Littlefields,

 

I've seen a few blowers like yours that looked like a back of rocks went through it, and the blower still kicked butt. Don't worry about it, just re-strip the rotors and have fun.
