If you have limited space in your shop, this idea will enable you to have a reasonably sized burning table along with your regular workbench.

     As can be seen, this table has casters attached to allow it to be moved around the shop as needed. Lay a plate on top and it can be used as a second workbench also. But the main purpose of this table is to save space while providing another tool in a more often than not overcrowded shop.

     It does this well by being made small enough to be stored underneath of a normal 4' x 8' workbench. The majority of its use will take place by simply hauling it out from under the workbench a few feet, and returning it underneath when finished. At the same time, it contributes to good housekeeping and safety by keeping burning and slag confined to one area, and off of the floor. The dimensions are for a guide only. Obviously it can be adapted to suit, but it should be made wide enough to ensure it is not top heavy.

     The box bottom, ends, and sides are made from 1/8" sheet, with sides being between 6" and 10" high. On each of the sides, there is a length of angle iron welded on the inside of the box. The crossbars will rest on these two angles, and the bars are spaced about 4" apart. This can be seen in the bottom drawing, which looks down on the top of the burning table. The tops of these crossbars should be slightly above the sides when put in place to allow larger pieces of metal to stick out pass the sides without catching. The crossbars are made of 3" x 1/4" flat stock. These bars will need a means of spacing them apart, as well as holding them on their edge. Flat stock that is cut approximately 3" x 4" long , or 2" pipe cut  4" in length will work to provide spacing. Weld the spacers onto the angle iron, leaving a gap for the crossbars larger than the thickness of the crossbars.
