1 inch impellor
« on: March 18, 2013, 08:18:49 AM »
 :D im learning!


i could post lots of pics but for now ill stay on topic....

a lil 1 inch impeller i maded 8)

lets see... sieg x2 with cncfusion ballscrew kit, big long steppers(iunno what torque anymore! lots!) and a gecko g540 (note other bits on keyring... a gecko and some motor mount i made for an rc bike but stuffed by forgetting about the sprocket... another topic!)

back to me gizmo. vertex 4 inch table with 2:1 belt drive. made on my machine too now i think of it!

STL file. dont ask...? scaled to 24mm dia, roughed with 2mm endmill, semi finished with 2mm ball, something like 0.5mm waterlines? snapped the only 0.8 i had almost instantly on final pass. cheap chinese carbide!  >:( where do i get sub millimetre bits from? im impressed with how ebay 3flute HSS endmills cut (a 2mm ender rapid plunged 7mm into ali is pretty good in my book...) but cant find much under 2mm in HSS...

oh. deskproto for the code... a few lil hiccups but still not bad for demo version!

Any planed projects for a small impellor like that or are you just showing off?   ;D

showing off i guess :) one of my friends kept hassling me though all i wanted to do was keep drinking... he got the first one cus i crashed it bad. this ones a keyring cus i crashed it too...

yeah, i do have a few plans... make a bigger, 3 incher, for the blower on my furnace foundry melting pot thingy...

i dont think theyll work too well as they get bigger cus the fins are just "slabs" not any real aerodynamically effecient profiles...  factor in balancing and so forth... wont ever spin to the speeds reached by a real impeller :( fine for a blower. uselss for a turbo compressor.
