Jet
 

Was looking through the "tear into" thread
Looked all the way through, but couldnt find a link to anywhere i could buy replacement impellars
Would any of them work
Not the whole unit
Just the shaft and prop

RE: Jet
 

if you get a new coupler and drill out the drive for the shaft

RE: Jet
 

ryanwilson is right. The tear into shaft is 2.3mm and the one the for mini jet is 3mm. Both are 19mm impellers. Other than buying another drive or making a new impeller by turning down one made for a 2mm shaft, It is the only option.

Turning it down? on a lathe?

I suppose you could use a lathe, but most use a drill press with the propeller to turn mounted on a shaft and spinning. And then use a file to turn down to the right size. The best way is to put the file in a "X" "Y" vise so that you can slowly apply the file to the spinning prop. Hope I didn't confuse you too much. I think dragonfire said he used a 26mm Graupner prop for a 2mm shaft to turn down. Good luck.
