The rods aren’t as fragile as they appear to you and absolutely nothing in this unit is connected by plastic. Yes, the rods could be bent, but I would argue that any tool is going to be damaged when you back a truck over them. Short of this or other gross misuse of the product, it seems unlikely that the nested steel support beams will be bent.
Below is a picture of the Centipede Tool team atop the smaller 2’ x 4’ prototype unit. With well over 500 pounds of man on this tiny little frame, we feel the durable nature of the product is apparent.
The polymer plastic P-Tops are there only to prevent marking the project board and to put enough space between the cutting blade and the steel frame. These P-Tops are replaceable after one too many misguided cuts hit them.
