      hi thanks dasboata but i was just wondering if this was a normal thing for a cnc prop one came and looks ready to try while the other definitely looks like it was not done completely leading edge is very thick weather i should return it and order another ?

      but since you brought it up what would you charge to do props?. I just don't have the time to do props lately and not very good at it wich is why i was trying the cnc prop a little less work involved i thought

          They come that way. I take a blue or red polishing pads (usually blue, not as course) in a 90deg air grinder on low rpm at work and then polish/sharpen them that way. I check the balance the best I can (cnc are light, but they can get out of balance). I love the cncs, wish there were more for the right hand CW props I need.
          If you don't have access to air grinder/polisher, by hand would work with a file for sharpening.

            I think there is definitely something wrong there Flanders.
            The leading edge looks a thick as the trailing edge. That's not right. I've never seen a CNC prop like that & I have more than just a few from different manufacturers. I'd be asking for another one. It should definitely look like the 42mm prop that you have. But even that could do with a bit of a sharpen. I touch mine up with a fine file & a bit of emery paper.
            See the danger. THEN DO IT ANYWAY!!!

              thanks for the help sent an email off with the same pics and asked about return but no response back so i attempted to sharpen and balance but may have done more harm then good. A week later i finally get a response about returning it for another but to late now and i am still without the prop i wanted first experience with company was not a good one!

                Just tell them everything. It was a dead prop any way.

                  Just an FYI. Some cnc props start out from a casting, not billet material. Saves machining time. Some are better than other. Buyer beware.
