Kalgorn,I was using 2x4's as an example, the wood in this "lift" is obviously of greater diminsion. Adding plywood sheating would increase the life span of this "lift" as well as to make it alot stronger by tying together the supports.

If he had this bolted down to a concrete floor in a garage I bet the majority of people would use it. BTW There is a thread about this "lift" on the garage journal

its got nothing to to with supporting the weight. its more to do with side and front to back loading.

put it to you this way.......put your fbod on there and torque down your crank pulley. while your going for that 137 degrees with the breaker bar and cheater pipe watch those side rail and cross boards. i bet you see them start to flex and push to the side....then a screw snaps and momentum builds and down it goes.

good idea......bad execution

thats rediculous if you look on the last picture the one from the front close up you can see the wood already bending down by the front wheels id like to see what it looks like after a couple of months. you would be stupid to get under this thing and the walls on the side would be annoying and would get in the way. i like the ol' jack and jack and stands.

Every now and then I will get under a car with a jack on one side and jackstands on the other side if supplies are short......but im always on the side with jackstands and i still feel uncomfortable. I would never get caught under that thing

if the car was on track instead of tires your math would work but his load points are more direct.

its not awful, just needs some tweaking. i would put 2 more verticals under each tire, use diagonal bracing to reduce side to side with slides and cotter pins for a simple breakdown and plywood the inside of the ramps to further decrease the risk of tipping forward or backward. other than the above and it being constructed out of wood and kept outdoors its not the worst idea.

i have stood on a coke slowly as possible and didnt hold up to 180 pounds, to me it looks as if the wind would blow that sideways, heavy metal shouldnt go on top of pine wood.

I can think of only one word......fuhdahshit. It's not even treated wood. All it would take is for him to come up or off of the ramp to fast and the whole thing lay down. Two horizontal supports, retarded. This is old as hell now, so he's either dead, or he tore it down.

I googled this one.......... I could say is an ok idea, but I would not make it out of wood and wood screws!
