Looks good Jim, how does it sound?
General consensus of family members who have been around when I've done some testing at different stages of the build has been "what the hell have you got running in the shed and hope you're wearing ear protection".
On air 20 psi starts to really get going, 40 psi starts to REALLY get going and making a sound like a 747 jumbo gunning the jets, 60 psi is pretty ear piercing (and scary speeds) and sound like a military fighter jet
Any pictures of the “guts”?
No, didn't even think to take any when building it.
Axle is running on bearings with a hefty 1" internal brass wheel with silver brazed thick copper sheet fan blades inserted into cuts on the brass wheel.
