Hello everyone from Slovakia,

my name is Taniq and I am building AR3 model. I have a small issue.

While inserting the J3 spindle into the J2 Arm, the washers of the bearing are sliding between the arm and the spindle. I had some problems to find the proper size, since most of the dimensions in the plan are USA. However I found proper one that match so far so good.

The four tiny screws that keep the spindle are set to a position enabling enough so that I can have smooth rotation. But in this case the second top washer starts to slide.

Please if anyone overcome this issue I will appreciate any advice. Pictures below.

Thanks in advance,
