Scott, I am truly apologetic for any problems with the prop and will work with you to make it right. Over torque must have been the cause of a faulty torque wrench because I did use one and yes I did follow the instructions closely as well as have someone who has a three bladed warp drive on their plane help me with the installation. Pretty simple to install a prop. As far as the spinner goes, it was never used or installed on my plane or anyone else's. It was returned exactly the way we received it. Also this is the first info I have had on this prop since I turned it over to Langford and you asked for it to be returned. If you wish to contact me by phone, please do so at 800-242-2219. If I damaged the prop, I am responsible and like I said, will make it right.

Prior to shipping you my prop for use in the KR prop bank, I had replaced all of the hardware. I had the propeller hub and spinner bulkhead Dye Penetrant inspected by a friend at work (I was working for a little aircraft company called Boeing), to insure serviceablity of the prop for aircraft use. Never mind the fact that the prop had been removed from a corvair powered soneri that had been flying with no issues...Yet,You reported a vibration from it, which you blamed on a balance issue. What is suspect is the manner in which you mounted my prop to your airplane. I had supplied you Warp Drive's website in numerous emails, yet the prop was way over-torqued. I also suspect that when you assembled the prop and hub, you didn't bother assembling the proper blade into the correct location and or re-index the prop hub halves. Can you not follow simple instructions? This is the condition that I recieved my prop back in: The bolts are stripped from obviously being way over-torqued. Missing bolts and nuts. The bolt heads have been stripped from the use of pliers. The prop hub has eyebrow inclusions on it where the prop attach bolts were over-torqued. The propeller hub has nicks / gouges on it. The spinner bulkhead has knife edge burrs in all of the attachment holes. I know the burrs were not there when I sent it to you as I had the prop hub and spinner bulkhead Dye Penetrant inspected and all of the holes were de-burred /chamfered. This is what needs to be done: Replace the stripped / missing hardware. Contact Warp Drive for the replacement hardware kit. Reimburse me the expenses required to bring the propeller hub back to serviceable condition. I'm going to need to send the hub back to Warp Drive to have it inspected, refaced or replaced. Replace the Spinner bulkhead. The bulkhead is now un-serviceable because in order to remove the knife edge burrs, the holes will get elongated and will cause the spinner to wobble, vibrate and fail. Please reference the email below that I recieved from Mark Langford prior to shipping me back my prop.

I never got a chance to test it using the vibration data logger due to time constraints, and never mounted it to the plane or did anything else with it since I brought it home from Jone's house. I took it apart to ship it tonight and two of the nuts were stripped due to over torquing. They were low height shear nuts, and over torqued by at least a factor of two, so that's not surprising. Jones reported a vibration from it, and that may have been why. I couldn't get the nuts off without drilling the end of the bolt/nut out, but that eventually worked without damaging the hub. I'd have put some new full height nuts in the box but my nut box is at the airport so I had to leave them out.
