Axle mounting tubes...
model40fan Saturday, 2/28/2015
Hobby Lobby has been mailing me BAIT... so I duct taped 1/2 of a FTE axle and put it in my pocket... when i got there I found ; K&S PRECISION METAL, #5100... 1/16" ALUMINIUM TUBE [6] 12" pcs. $3.00... the axle slides into the hole tightly... perfect
so as not to crush the tube when cutting it, I may file it off...

They also sell fine rods that fit inside those tiny tubes. I found the longer stick, works well to round out inside the tubes after cutting. Just easier to hold and work with than an axle.
Also, they spark when cutting. Watch your eyes and flammables.
