Sal, Woodz, I think you guys are missing the main point of Davids motor, low weight. THAT is fundamental to the design, using sleeves would just not be logical in this endeavor due to the weight penalty. Like many exoctic applications one has to weigh the 'long term' risk against the benefit, for some this will be a thing of beauty!
As for bragging rights, a BILLET motor? Whoa, thats some serious 'talk story' headlines there, just look at THIS thread!
