It has been approved for use at any site which permits the use of hibachis by the West Kingdom Fire Marshall. The only repair it has required in that time is the replacement of the fire-grate after a year and a half of use. ਀ഊ ਀ഊThe general design is shown to the left. It is a bowl which is a segment of a sphere suspended on a tripod which runs through holes in the bowl. In the bowl is a flat fire-grate made of expanded metal which holds the fire off the base of the bowl, keeping it cool and allowing a place for ashes to fall. The tripod additionally supports the grill on which you cook, or can be used to suspend a pot above the fir. The bowl is constructed of six fan-shaped plates which pivot on a central bolt and latch together with hooks to form a rigid structure. The fans are overlapped so that there are no open gaps through which coals might fall to the ground. ਀ഊ ਀ഊThe dimensions of this pit may be adjusted to suit your own needs. I here give the general method of construction as well as the dimensions which I used for my pit. Refer to the plans. First decide what diameter you wish your pit to be, and how deep you want it. I decided that 30 inches diameter and 5 inches deep was about right if I was going to use the particular grill I had in mind, and the piece of scrap steel I had just found. The combination of the radius of the desired bowl, r, and the depth, d, determine p, the radius of the sphere from which the bowl will be "cut." This in turn determines the arc-length, s, from the center of the bowl to the edge. Both r, the radius of the bowl, and s, the distance along the bowl from center to edge, are necessary to measure the fan-pieces. Note that the difference between r and s for my firepit is only 1.1 inches. This is critical! The fans are designed so that they will be edge-to-edge only at the rim of the bowl and will overlap everywhere inside the bowl. The 2-inch width at the center was determined empirically and works fine. ਀ഊ ਀䤀 眀愀渀琀攀搀 琀漀 栀漀氀搀 琀栀攀 戀漀眀氀 琀漀最攀琀栀攀爀 眀椀琀栀 挀氀椀瀀猀 愀渀搀 䤀 搀椀搀渀✀琀 眀愀渀琀 琀栀攀洀 琀漀 挀漀洀攀 漀甀琀 眀栀椀氀攀 琀栀攀 戀漀眀氀 眀愀猀 椀渀 甀猀攀 愀渀搀 瀀攀爀栀愀瀀猀 樀愀爀爀攀搀 戀礀 愀 瀀愀猀猀攀爀ⴀ戀礀⸀ 䤀 琀栀攀爀攀昀漀爀攀 瀀甀琀 琀眀漀 挀氀椀瀀猀 漀渀 攀愀挀栀 漀昀 琀栀爀攀攀 漀昀 琀栀攀 昀愀渀猀 愀渀搀 琀眀漀 猀氀漀琀猀 昀漀爀 琀栀攀洀 漀渀 攀愀挀栀 漀昀 琀栀攀 爀攀洀愀椀渀椀渀最 琀栀爀攀攀 昀愀渀猀⸀ 吀栀攀 挀氀椀瀀猀 愀爀攀 漀昀 ㄀㘀ⴀ最愀甀最攀 猀琀攀攀氀 愀渀搀 爀椀瘀攀琀攀搀 琀漀 琀栀攀 昀愀渀猀 猀漀 琀栀愀琀 琀栀攀礀 挀愀渀 猀眀椀瘀攀氀⸀ 一漀琀攀 琀栀愀琀 琀栀攀 猀氀椀琀猀 猀栀漀甀氀搀 戀攀 挀甀琀 猀漀 琀栀愀琀 琀栀攀礀 愀爀攀 爀愀搀椀愀氀 琀漀 琀栀攀 挀攀渀琀攀爀 栀漀氀攀Ⰰ 渀漀琀 瀀愀爀愀氀氀攀氀 琀漀 琀栀攀 攀搀最攀 漀昀 琀栀攀 昀愀渀⸀ 匀椀渀挀攀 琀栀攀 挀氀椀瀀猀 挀漀洀攀 漀瘀攀爀 琀栀攀 琀漀瀀 漀昀 琀栀攀 昀愀渀猀Ⰰ 琀栀攀 猀甀瀀瀀漀爀琀 爀漀搀 栀漀氀攀猀 愀爀攀 搀爀椀氀氀攀搀 椀渀 琀栀攀 昀愀渀猀 眀椀琀栀 琀栀攀 猀氀椀琀猀⸀ 吀栀椀猀 洀攀愀渀猀 琀栀愀琀 愀氀氀 琀栀攀 昀漀爀挀攀猀 最攀渀攀爀愀琀攀搀 戀礀 眀攀椀最栀琀 漀渀 琀栀攀 戀漀眀氀 眀椀氀氀 琀攀渀搀 琀漀 栀漀氀搀 琀栀攀 挀氀椀瀀猀 椀渀 琀栀攀 猀氀椀琀猀⸀ 䤀渀 愀搀搀椀琀椀漀渀Ⰰ 琀栀攀 昀愀渀猀 眀椀琀栀 琀栀攀 挀氀椀瀀猀 愀爀攀 漀渀 琀栀攀 戀漀琀琀漀洀 漀昀 琀栀攀 猀琀愀挀欀 漀昀 昀愀渀猀Ⰰ 猀漀 琀栀愀琀 琀栀攀 渀愀琀甀爀愀氀 猀瀀爀椀渀最椀渀攀猀猀 漀昀 琀栀攀 洀攀琀愀氀 椀猀 眀漀爀欀椀渀最 琀漀 欀攀攀瀀 琀栀攀 挀氀椀瀀猀 椀渀⸀ 吀栀攀 昀愀渀猀 愀爀攀 栀攀氀搀 琀漀最攀琀栀攀爀 眀椀琀栀 愀 ㄀⼀㈀∀ 戀漀氀琀⸀ഊ ਀䤀 漀爀椀最椀渀愀氀氀礀 琀栀漀甀最栀琀 琀栀愀琀 䤀 挀漀甀氀搀 氀攀愀瘀攀 琀栀攀 洀攀琀愀氀 瀀氀愀琀攀猀 昀氀愀琀 愀渀搀 栀愀瘀攀 琀栀攀洀 戀攀渀搀 甀瀀 渀愀琀甀爀愀氀氀礀 琀漀 昀漀爀洀 琀栀攀 戀漀眀氀⸀ 唀渀昀漀爀琀甀渀愀琀攀氀礀Ⰰ 琀栀攀 ㄀㘀 最愀甀最攀 猀琀攀攀氀 搀漀攀猀渀✀琀 戀攀渀搀 愀氀氀 琀栀愀琀 攀愀猀椀氀礀Ⰰ 猀漀 䤀 栀愀搀 琀漀 挀爀攀愀猀攀 琀栀攀 昀愀渀猀 愀猀 猀栀漀眀渀⸀ 吀栀攀 挀爀漀猀猀ⴀ眀愀礀猀 挀爀攀愀猀攀 椀猀 愀戀漀甀琀 㜀∀ 昀爀漀洀 琀栀攀 猀洀愀氀氀 攀渀搀Ⰰ 愀渀搀 最椀瘀攀猀 愀戀漀甀琀 愀 ㈀∀ 攀氀攀瘀愀琀椀漀渀 愀琀 琀栀愀琀 攀渀搀⸀ 吀栀攀 爀愀搀椀愀氀 挀爀攀愀猀攀 爀甀渀猀 椀渀 昀爀漀洀 琀栀攀 攀搀最攀 愀渀搀 最椀瘀攀猀 愀戀漀甀琀 愀 ㄀∀ 琀漀 ㄀ⴀ㄀⼀㈀∀ 攀氀攀瘀愀琀椀漀渀 漀昀 漀渀攀 昀氀愀琀 眀椀琀栀 爀攀猀瀀攀挀琀 琀漀 琀栀攀 漀琀栀攀爀⸀ 吀栀椀猀 愀洀漀甀渀琀 漀昀 戀攀渀搀 洀攀愀渀猀 琀栀愀琀 愀 挀攀爀琀愀椀渀 愀洀漀甀渀琀 漀昀 昀漀爀挀攀 椀猀 猀琀椀氀氀 渀攀挀攀猀猀愀爀礀 琀漀 栀漀漀欀 琀栀攀 戀漀眀氀 琀漀最攀琀栀攀爀Ⰰ 眀栀椀挀栀 栀攀氀瀀猀 栀漀氀搀 琀栀攀 栀漀漀欀猀 椀渀 瀀氀愀挀攀⸀ഊ ਀䤀 洀愀搀攀 洀礀 昀椀爀攀 最爀愀琀攀 漀甀琀 漀昀 洀攀搀椀甀洀ⴀ眀攀椀最栀琀 攀砀瀀愀渀搀攀搀 洀攀琀愀氀 ⠀琀栀攀 氀椀最栀琀ⴀ眀攀椀最栀琀 眀漀渀✀琀 栀漀氀搀 猀琀椀挀欀猀 愀渀搀 猀甀挀栀Ⰰ 愀渀搀 琀栀攀 栀攀愀瘀礀ⴀ眀攀椀最栀琀 眀愀猀 琀漀漀 攀砀瀀攀渀猀椀瘀攀⤀⸀ 䤀 爀攀椀渀昀漀爀挀攀搀 椀琀 戀礀 戀攀渀搀椀渀最 椀琀 椀渀琀漀 愀渀 漀挀琀愀最漀渀 爀愀琀栀攀爀 琀栀愀渀 挀甀琀琀椀渀最 椀琀⸀ 吀栀攀 昀椀爀攀ⴀ最爀愀琀攀 昀漀爀 洀礀 瀀椀琀 椀猀 ㈀㐀∀ 搀椀愀洀攀琀攀爀⸀ 吀栀椀猀 瀀甀琀猀 椀琀 愀戀漀甀琀 ㄀ⴀ㄀⼀㈀∀ 戀攀氀漀眀 琀栀攀 氀椀瀀 愀渀搀 眀攀氀氀 愀戀漀瘀攀 琀栀攀 戀漀琀琀漀洀 漀昀 琀栀攀 戀漀眀氀⸀ഊ ਀ഊThe tripod I made out of 1/2" hot-rolled steel rod. I flattened one end of each, drilled a hole, and put a heavy loop through to keep the pieces together. About 12" down I drilled a small hole and put through a hook to catch the chain that supports my cooking-grill. About 9" from the other end, I drilled a hole for the support pin for the bowl, and about 2" above that a hole for the cotter pin to hold the chain that acts as a keeper for the pin (to keep the pin from getting lost). I used nails for the hooks and pins. ਀ഊThe height of the tripod is largely a matter of taste and appearance. I used four-foot lengths of rod because that looked right and because it allowed for a certain amount of movability for the cooking grill. The lower the tripod, the less adjustable will be any given grill. The higher it is, the longer the piece of rod you will have to transport. My cooking grill is 15" x 24" and has three light chains brazed onto it, on at the end and two on either side about two-thirds of the way down. These I wrap around the tripod rods (to reduce sway) and then hook on the little hooks at the top. These stay cool and I can adjust the height of the grill while cooking by easing the strain on the chain, then adjusting it up or down in increments. ਀ഊNotes on use: Although the bottom of this pit does remain cool, it is always a good idea to put a board under it if you are setting up on dry grass or in tall grass. If the fire danger is extreme, clear the area around the pit just as you would for any other fire. ਀ഊIMPORTANT NOTE: Use of these plans to make a firepit for personal use is permitted and encouraged. If you are thinking of setting up in business making firepits, please talk to Frederick first to arrange licensing.
