J4 main tube / shaft sizes?
Hi Chris,
I've chosen the way to print the structural components for my AR4. And as the manual says "The J4 tube cannot be 3D printed", so I need to make it. Unfortunately, I can't find in the manual the exact sizes or technical drawing of the shaft for me to cut it and drill the holes.
I checked the stl model (J4 Main Shaft.STL), it looks like 25,4 mm outside diameter, 3mm thickness and 116,3mm length.
So I suppose the standard 25mm aluminium tube will work too, right? Can you please confirm the sizes and the holes positions?
My apologies I need to add the tube specs to the manual. It was in the previous manual but got removed. Here is the information:
