  • my robot is about 100lbs and is okay. I used lock tight on the set screws and that helped. I don’t know is I’d go much more than that.

  • I got a few set of these to mount a pinion gear to my project. Two of these where ok but on two of them the bearings were too tight and did not spin freely. I think these parts may work well to hing two channels together or something, but I ended up using an other piece of channel and two flanged bearing to hold the a spinning shaft.

  • 6-32 Socket Head Machine Screw works well to connect the the 0.77" hubs.

  • Wow I like this stuff. I just received and and assembled me first order and it and it works well and feels very strong and ridged. I got most of the parts right but I missed adding the spacers, this gear is off an1/8" from the 16 tooth pinion gear and the spacer will make that up. Also it looks like it’s a good idea to uses them between bearing and the gears or collar.

No public wish lists :(
