I love projects that seemingly simple materials become very useful and functional.A bit of cement, cedar beams and a few screws - it's all that we need today.
for concrete slab benches need our standard bag of cement and sand.First, create a form: Take a sheet of melamine sizes 2 to 4 feet and 5/8 inches thick, they are available in many DIY stores.Using a hacksaw or circular saw, cut the base of the right size.In my case it was 13 ¼ inches wide by 37 ¼ inches long.Then cut pieces for the long and short walls of melamine 3 inches thick.To assemble the base, attach to the bottom of the long wall with bolts, every 5 inches (quite suitable conventional wood screws at their small diameter, there is no need for pre-drilling holes).Gluing yet should not be, becausewe have a temporary basis, and will subsequently be dismantled.Attach the remaining three walls to the base in the same manner, then to consolidate the structure by adding a pair of screws at each corner as shown.
Put the form on a hard flat surface and align the corners to form spacers was parallel to the horizon.This is an important condition for the establishment of a concrete slab the correct form.Then apply to the inner surface of a thin layer of vegetable oil, so that the concrete did not cling to the surface.
You can mix concrete in a concrete mixer, but I prefer to do it in a clean plastic trash can with the nozzle to the usual drill.Pour cement in a container and add the sand and 2 liters of pure cold water, consisting of concrete is also desirable to use a latex bonding (this liquid is sold in DIY stores under different names).This anchoring concrete structure helps evenly distributed in the form of the final product will get better and will not crack.Stir structure carefully, until all lumps disappear.Scoop then the entire mixture in your form, for that I use plastic milk container.Spread the mixture on the corners, gently tapping on the walls with a rubber mallet.The level of the concrete should be ¼ inch below the edges of the form.Wait a few days, when the concrete hardens, and remove the frame to release the plate.Remove sharp edges by grinding or using a medium-sized stone.
legs and cross bar.
Cut the cross and bench legs, better with the saw blade, circular saw, too, but it would be appropriate.All the bars are connected directly to the squares.(Some vendors sticks carved with holes).Mark the holes for the screws at the top of the legs and at the ends of cross members.They are fastened by pins 10 inch length and ½ inch diameter bolts at both ends.Promazhte glue each connection, it will prevent the collapse of the structure, if the bolts pluck.Drill holes for washers and nuts on the outside leg on the center hole 1 ½ inches wide and an inch deep, and then drill a hole for the pin.Assemble the frame by sliding studs and firmly tighten nuts.
Cedar will remain long in the open air and eventually becomes gray if you want to color was brighter, use the outer cover.I've been using varnish Sikkens Cetol, which I consider the most effective.You can cover plate filler layer to protect it from water and sediment.
