Do you thing that filling the outside tubes with concrete would have a noticeable impact on the overall rigidity of the system? You would not want to fill the tubes that cross in the middle as it would add a lot of mass that the motors have to move around.September 24, 2017 at 3:43 pm #44639
This gets asked often enough it should be stickied. It will add some, but not really worth the hassle. Mid span supports are way easier.September 24, 2017 at 6:22 pm #44653

How it works isa single set of mid span supports add more than 4x’s the rigidity, concrete would not and make a huge mess.October 17, 2017 at 12:13 pm #46187

Is there a STL file for mid span supports?October 17, 2017 at 12:24 pm #46188How it works isa single set of mid span supports add more than 4x’s the rigidity, concrete would not and make a huge mess.

I just used what’s in the second picture. Just drilled a hole in the tube, and used a locknut on the bottom of the tube to hold it. Nothing inside the tube is really needed, it just keeps it from sagging.

Hey Barry what’s your working area?November 9, 2017 at 5:19 pm #47771
It was almost 4 feet square. I’ve put it back to about 2 feet square since building the lowrider.February 21, 2018 at 8:01 am #53470
Barry, how well did it do with the 4×4 setup? Asking because I’m thinking of doing the same. Also was it hard to load a 4×4 in from the top since the midway supports are in the wayFebruary 21, 2018 at 9:41 am #53480
It worked okay. Works better smaller though. I use the lowrider for bigger things now.
