You can tighten it by drilling a hole right behind the head of the bolt, so you can get an allen key to it. It's hrad to describe so this may not make sense. If you use Loctite it will suffice for a frame. My did it in 2008 and it worked just fine.
I think I understood. Our team has used 8020 for years, just I'm one of the few surviving people who know how to use CAD.

This is going to be fun. Whee...

I wish I could drag Inventor windows to my second monitor, would be soo much easier than flipping back and forth to see my measurements.

Re: 8020 Mass

go to where you would edit the color- then go all the way down to material styles, then open that, then double click on aluminum 6061, it should turn bold, then the entire solid is recognized as aluminum 6061, including the mass

Thanks, but as far as I know if I model a rectangle 1"x1"x12" it'll model the mass as a solid piece of Aluminum with the same volume.

Re: 8020 Mass

yes, you must put the thickness of the tubing into the sketch, but if you use extruded 80/20, it will do the shape

Re: 8020 Mass

I would also verify the weight of your piece. Library components may have simplified fillets. 80-20 is a complex extrusion, some components dont model all the detail and then your weight will be off a bit.

Re: 8020 Mass

Make certain that when you are calculating mass you take density out to at least 4 decimal places - especially in an SI (millimeter -gram-second) units.
