Looking good. As with others of this design...how's the side load stiffness?
Thank you fretman_2.
It feels stout so far. I think the epoxy embedment along the full perimeter of the shear plate makes the side panels quite twist resistant. There are three 3030 cross beams connecting the side panels with large corner brackets. One of them is not visible behind the gantry. See attached pic. So far I didn't see a need for them but larger flat brackets could be added to front and back if necessary.
Btw, how do you make the posted pictures show up larger? They all end up posted as smallish thumbnails but are at the 1025 pix and 500kB limit?
I tried it both as attachment and as image but no difference. Thanks.
