Every homeowner needs a workbench where he can do those small repairs that seem to pop up every weekend. But not every homeowner has the space for a bench. If you lack the space for a permanent bench, maybe one of these two ideas will solve the problem.

SAWHORSE BENCH. This is cheap and easy to make, and it's portable so you can take it to the work. Use it outdoors when the weather is good, in the basement or garage when the weather is bad.

To make it you need a couple of pairs of folding sawhorse brackets, a pair of 12 feet 12 inch x 4 inchs, one 8 feet 2 inch x 4 inch, and a piece of 3/4 inch plywood for the top. A whole 4 feet x 8 feet sheet will give you a huge work surface, but it will be hard to handle; a 4 feet square is a good compromise.

Cut the two 12 feet 2 inch x 4 inchs into eight pieces three feet long. These are the tops. Fasten these parts together using the folding brackets. Stand them up with the sheet of plywood on top and you are in business. When the job is done, take off the top, fold up the horses and store the whole bundle away until next weekend.

FOLDING BENCH. This one, shown in the sketch, will take a little more effort, but it's sturdier and easier to put up and take down. It can fasten to any wall in your garage, basement, furnace room or wherever.

To start, cut four 2 inch x 8 inchs and one 2 inch x 4 inch to the length of your bench. Fasten the 2 inch x 4 inch to the wall 1 1/2 inches below your desired bench height. Use 20-penny spikes into the wall studs if the bench goes on a frame wall. If the wall is masonry, use lead screw anchors and 4 inch lag screws. Then fasten the verticals in place, centered over studs if the wall is framed.

Next, make two triangular brackets using 2 inch x 4 inch stock and 1/4 inch plywood gussetts. Fasten them together with 1 1/2 inch (four-penny) nails and white glue. Then fasten one of the 2 inch x 8 inchs the top of the 2 inch x 4 inch on the wall using 16-penny nails.

To make the bench top, fasten the remaining three 2 inch x 8 inchs together with 2 1/2 inch No. 10 screws driven through 2 inch x 4 inch cleats. Stagger the screws to avoid splitting the cleats.

Fasten the two brackets in place on the uprights using a pair of 3 inch T-hinges for each bracket. Make sure these brackets are pushed up tightly against the 2 inch x 8 inch. Finally, fasten the bench top in place with a pair of heavy 6 inch strap hinges.

That's it. To use the bench, raise the top and swing the brackets out at right angles to the wall. To store it, fold the brackets inward and lower the top. The 2 inch x 8 inch anchored to the wall serves as a shelf while the bench is folded away. CAPTION: Illustration, no caption, Copyright (c) , 1978, Popular Science.
