We really are in need of: 24t x 9mm Wide Double Flange Aluminum Pulley (GT2 3mm, 1/2" Hex Bore) (x4) and 46t Aluminum Spur Gear (20 DP, 1/2" Hex Bore) (x2). It’s our faults for not ordering sooner, but it is core to our robot design. Is there any way we can get these parts?
My team last year needed was able to machine a hex bore through a pulley we purchased at SDP-SI, but we ran into the issue of the corners being rounded, but that didn’t give us any problems for the load being applied. Since then, we have purchased a hex broach that will help with stuff like that. We also 3D Printed some pulleys as a temporary fix to something until we could order more aluminum ones but after 70+ matches, never failing us, we are purposely 3D printing pulleys this year due to light weight and being cheap, plus quick turn around time.
I believe we used SDP- SI CAD for printing the pulleys, but they are coming straight off of CAD and then we modify the design a little bit to change little pockets that made have been added that weren’t really needed.
