I am trying to design and fabricate an Engine Support Bridge. For those not familiar this would be similar in function to a hoist but it is a framework that would fit over the engine (in a car or truck) and be supported at two points on the cars inner fender lip that meets the hood. Basically this would consist of a horzontal bar about 48 inch long supported at two end points about 12 inch above the engine. This is a rough idea of what it should look like. I will hang chain from the horizontal piece.
=================================== x x x x x x
I want to know what type of steel and form I should use. It has to be weldable (I have access to gas welding). The frame should be capable of supporting 350 to 500 lbs. I am thinking something tubular but since I dont have any depth of knowledge on whats available I thought i would ask.
thanks
Tim
