    Default Heavy Duty Sawhorse Design

    Had a quote to do for a guy today & would like your ideas for material requirements & design. Each unit must hold 1500 lbs. & 4 for a total of 6000lbs. I think I know how I am going to do it but extra input is welcome as far as design & material. Look forward to your input & if we get the job pics will follow progress. Thanks for now.

    Default Saw horses

    I would start with a square base of 3" x3"x1/4 " angle iron the base can be as big as 24"x24" or bigger,keep in mind tipping or top heavy, weld all corners flush so you have a nice square floor flush base ,in the base find center on the sides and weld two 3"x3" x1/4" angle iron perpendicular across to the other side flush on the square making the width 4" apart to accommodate a 4"x4" steel tube stock in the middle of the cross section ,weld the tube stock down into the two angle irons where connection is made...tube stock to be hight desired less 4"...now take and angle cut [4] 3"x3"x1/4" pieces long enough so the pieces go from each bottom corner up near the top of the center 4" tube stock you will have 4 pieces welded on the 4 corners of the tube stock and the four corners of the base...it will look like a pyramid...at the top on top of the 4" center tube stock will be the 4"x4"x3' tube stock..find center and weld on top of the center tube stock from the base..you should weld all 4 contact points where center tube stock meets top tube stock...you should have a big T supported by your pyramid base...now I would take two 4" tube stock and cut 45 degrees on both ends, lengths to go under your top 3' piece as underneath supports, they can be as long as you think you need to support the top rail, they can be welded at the base of the 4" tube stock and go right out to the ends of the top 3' tube stock if you think you need this much support. Weld them underneath unto the center 4" tube stock and under the top 3' 4" tube stock...this should carry aolt of weight...if not you can always beef all the materials up...I just might build some of these ...you got my think juices going..DanQweld ................ a simpler version take the tube stock cut a 3' piece put on floor take two 2' pieces weld at each end of 3' piece to form a H..take two 1' pieces and weld oposite eachother in the middle this is your floor base the tube stock flat on the floor with three supports... at center weld up your middle 3' vertical piece, support this piece with two 45's, on top of the middle piece run your 3' piece at the ends of the 3' pc support with tube stock under top pc to bottom pc weld supports if you think they need.....simple but strong, if you do not have a length of rail road rail handy...

    Just an idea that I "borrowed" from work. We use C-channel for the tops of all of our horses, open side facing up. This might sound strange but it actually make the the horses far more versatile. With any large flat object they will sit just like normal, but if you have something with a lip on it you can position it inside the channel to keep it from moving around. Furthermore, you can drop in a piece of dimensional lumber that is a little taller than the chanel if you need to work on something that you don't want getting scratched. Just a though.
