![]() ![]() Screw the metal into the left-hand edge of the back upright and the side of the front upright parts of the frame, and bend it around. Then fit the bend part to the back left-hand upright of the frame, with the remaining sheet metal going towards the front left upright part. Using the hammer, bend the 1” part until it reaches 90 degree angle to the rest of the sheet. It will be a cut out from the 26 gauge sheet metal with a total parameter of 16 “plus extra 1″ (which again should be marked using the marker pen). The first layer of metal covers the fire box area. Once all is done, place the frame inside the base piece of metal. Then, make a frame around the ashtray opening by welding two 7 and a half inch vertical, and one 8 and a half inch horizontal pieces. Then weld a 19″ piece between the right-hand uprights, at the top. To the right of this mark weld another 19″ piece.įor the front part of the frame, you will need to weld a 28″ piece horizontally between the front, left-hand upright and the front right-hand upright. Measure 13″ from the left-hand edge of the 37″ horizontal piece, and mark the spot. A horizontal, 36 and a half inch square tubing piece run horizontally, and it is welded between the 34 ” left-hand upright and right-hand upright pieces. The two left-hand upright pieces of metal should be 15″ tall, the piece that connects them is 16″. Building of the frame is quite difficult to describe in writing, so it could get a bit confusing at times. Please do refer to the picture at all times along the way. Before we continue with putting it all together, here are the lengths of the cuts of square tubing that you will need to prepare: 15”, 15”, 16”, 36 ½”, 19”, 34”, 34”, 28”, 19”, 8 ½”, 7 ½” and 7 ½”, making a total of 20 ft, or one piece of tubing. Here it is very important to get the measurements right. In any case, even if a welder is not available, make sure that you are not alone there, just in case. If you are not an experienced welder, it might not be a bad idea to call a specialist to guide you or at least supervise what you do. Here you will need some good welding skills, and suitable protective gear. This is one of the crucial steps, as the frame would hold the walls of your RMH. Draw a circle with a diameter of the size of your stovepipe. You can do this easier by hanging a plumb bob from the center. The last thing to do here is to put the base in place, and mark the metal where the stove points down. Again, if you would like to stick to the tested design, then the 6 and a half inch wide ash box will start at 6 and a quarter inch from the left front corner. Cut the flap at the place where the ash box will slip in. Then, with the snips, cut from each corner into the drawn line and then bend the flaps upwards using the pliers, so that they can be bolted to the wall. Using the marker pen, draw an outline that indicates the 1″. If you would like to stick to the “done and tested” version, then you would need a 46” x 18” (48” x 20” including the 1” flap) cut out. The size of the piece should be 1 inch bigger (on all sides) than the space where you want to fit the unit. To build the base, you need to cut a piece of the 26 gauge sheet metal. This step is needed in order to contain the sand, which in this case is used as a thermal mass. Heat resistant, non-flammable clothes, gloves and goggles.Saw, with both metal and masonry blades.You will also need the following equipment: High temperature resistant silicon and paint.6″, quarter of an in thick well casing pipe.To build the Rocket Mass Heater you will need to get the following materials: 5% Discount Code: GREENOPT Materials and Equipment ![]() Also read: This Device Extends Your Phone's Battery Lifespan Like Nothing Else. ![]()
