    pmf's AR3 Build from Massachusetts

    in Robot Builds

    Parts acquired, now to build...

    I have already printed the covers and have started on the electrical cabinet. All of my screws and smaller "stuff" is located in the Akro-Mils Bins and wringing and larger "stuffs" is in the clear bucket.

    I may send the aluminum pieces out for bead blast and black anodizing, not sure yet.


    My 5v power supply did not have mounting holes like Chris's, so I 3d printed a bracket which mount to the two holes in the bottom of the supply.





    I also had a difficult time marking the larger power supply mounting holes using the paper method, so I 3d printed a drill guide which worked great. I don't have a picture of it, but here is a render. The bottom ledge rests on the grid board, and the cutout on the lower right side is so that it can reference the side wall of the cabinet without hitting the inside radius.

    I was having trouble adjusting the feel of the J3 bearings. Upon closer inspection, It looks like the flathead screws are slightly proud of the surface. I hated to do it to the nice anodized part, but I used a diamond stone to lap the screws flush with the surface. The bearings feel much better now.
