Take the BBQ hand blower to the next level!! Add a 3rd stage or as many stages as you like to make sure your BBQ hand blower becomes the LEAF BLOWER 3000!!!! Using the 2 stage gearbox by Gavitka, it is 4:1 ratio per stage. Two stages is 16:1. Add this 3rd stage and its now 64:1. Add a 4th stage and you are in finger chopper and impeller explosion territory!!! To help all those who are two weak to turn this torque monster (Including myself), is the extended handle. It is double in length and looks ridiculous, but you now have the power to blow anything away. Now for some math. I have only added a 3rd stage with the extended handle. It is difficult to try and crank at a pace of one revolution per sec.You really feel the load on the impeller. So being able to crank 60 times in one minute will get your impeller to 3,840 rpm. (Watch out kids!). This uses the 24t planetary and sun gears from the 2 stage gear box. Use M3-16mm bolts and nuts to hold everything together. Make sure you orient the parts before printing. No supports are needed. Have fun and watch your fingers!
