Zahry, I intend to bolt mine down.
I think plastic may not be up to the job especially at those narrow tab points.
Maybe if the plastic disk came right out beyond the screw holes it would be stronger.
Another problem with plastic is that it is obviously light weight.
Most of the weight, and thus stability, of the Warthog is in that big metal base.
Take that base off and I think you almost have to bolt it down to something.
Originally I was thinking of just a weighty stainless steel disk say about 3mm or more thick and about 2cm greater diameter than the Warthog itself. It would just need predrilled holes to attach the Warthog and around the circumference about 10mm in from the edge.
