there it is. I will be boring my pump on a single axis harbor freight drill press as soon as i get the tool path's programed in. The impeller will be held on the drive shaft with drywall screws and tree sap.

I still need to modify a mailbox for my new pump shoe.

i just read through this entire 17 page thread and to be honest i thought he was going to prove you all wrong then V came out and busted him...thats classic. kinda reminds me of that jaminjetski guy last summer that had all these awsome parts for crack head prices. hey some check his url # make sure its not the same guy...
 
amazing thread, worth reading the whole thing. there was some funny sh*t on here. i knew from when it started he was full of it. too much money to build not to mention the machining time and machines involed. plus there are lighter materials that could be used to make the same project. i ACTUALLY work in a machine shop that works on a lot of aerospace parts. anyways, nice thread.

Using a titanium alloy bit for my drill I CNC'd an impeller using precise motor skills and a 6,000 RPM Black and Decker multiple axis, variable speed, variable bit size, brush motor powered hammer drill. Using TLAR and some common enginuity, it was quite simple to CNC a simple variable pitch impeller out of plastic, which will not only act as a lightened flywheel, but the pitch flattens at high RPM for better low end, while it expands during lows, so you get a high speed idle capable of maintaining plane, and when you want to get into the power, the torque is multiplied by a factor of about 5.6. This number is an approximate however, and with a few breeds of plastics that are commiserate in durability to that of memory metal, and of equitable strength to some of the better aircraft aluminums that I am working with in the future, this number is expected to GROW!
