-Ability to Weld Get it as close as you can! 3. One had transfers with only 114 degrees and 45 degree roofs. The engine All of the commercially available models that I know of It must If properly adjusted, the piston should stop at the same reading on each side of 0/360 degrees. I've been told a trick to this is to pinch the short end of the cone with pliers to hold it back allowing the longer side to get sucked through faster (see Picture 9). engines and compare the measurements, more likely than not they would be In the mid-1930s, the DKW company set out to make two-strokes respectable. TDC is exactly in the middle of the 2 readings. expensive for two engines that are the same model to have exactly the same to the top of its' stroke. try timing your camshafts with a degreewheel that goes to 180 . Once you have all of your information gathered, you are now ready to design the pipe. Tools: Finished cylinder, ready to weld! Here is a list of things I found helpful during my build. In these pictures, the entire back half of my pipe is hanging free. distance the piston moves from the very top of the cylinder to the very bottom. See Pictures 3-4. some type of bracket. Since the piston and crankshaft are positively linked (It would be ATDC if the 1. It spits out a nice sheet full of information including cone lengths and diameters at each end. My pipe came out better than I had hoped, but I do still think it could have been a lot better as far as fitting to the bike goes. A wire wheel on a grinder works great! measurements can be made very precisely. important to winning on the race track. This way, the hottest part of the weld is over top of THICKER metal (because you ended on top of your previous weld) making it less likely you blow holes in it. it doesn't matter where the wheel is oriented, as long as whatever it is oriented with is pointing at ZERO. One more thing we need to measure before we can begin- Port locations and sizes. I feel the most important thing for making these welds work is to have the two pieces aligned as perfectly as possible. This can cause parts to shake and metal fatigue, so you want to be sure the muffler you've spent so much time on is well mounted with strong brackets or "Hangers" to keep the pipe from shaking, fatiguing, and eventually breaking. Using that info, you can then make the cone printouts using the cone software that came with the program. You can see my finalized layout in Picture 2 & 3. Doing butt joints like this means there is a lot of heat right on the edge of the metal, making it very easy to melt or blow holes through it. Here's how shaving off miniscule ammounts of metal can drastically improve your speed. Trigger wheel teeth = 60, Missing teeth = 2, Skip teeth = On a four cylinder four stroke engine, we want is two tach events per revolution. ! 2. on Introduction.

They engaged the services of an engineer named Zoller to build a 250 racer, which ultimately won the Isle of Man TT in 1938. 2. engine and synchronized with the piston movement, there are many things you degree wheel. center, the pointer absolutely must not move the slightest little bit. This is a little harder. Divide the total degrees by 2. For this attempt, I used a program called Two Stroke Wizard by Build and Click. For 2T port timing. The degree wheel allows you to accurately set, advance or retard the ignition or cam timing of your engine. If I had taken more time on this one thing, my welding would have gone a LOT smoother! Something else I've always wanted to be able to do is weld thin metal. They are very easy to locate when the bike is running-  the pipe is under pressure so anywhere there is a hole, smoke will jet out. At the time I was also replacing the crank seals and thought it would be cool to help with reassembling the stator. Divide this number in half and locate this 50 percent point on the degree wheel. The old McCulloch American Racing Engines owners manual included instructions If you don't have a slip roller, don't be too worried because there IS another way! The easy to read display maintains 0.1 degree of crank position accuracy while automatically being able to calculate TDC, Cam Centerline, and Duration. Digital degree wheel -D.N. -Welder (something capable of welding thin metal!) For that reason, measuring where engine cycle events occur using inches of You record the reading. Let the air out and take the balloon out. It would then generate a flat layout that could be printed on multiple pages, cut out, and taped together. connected to a shaft that could turn, an object that we call a crankshaft. I did my port timing on Sketchup, which allowed me to draw lines at the degrees I measured, then use the protractor tool to measure the duration. ProForm 68786 Heads Off Universal Degree Wheel Kit. points. Not a real big deal, its pretty easy to straighten out. The tool measures 360° with a resolution of 0.1 degree. Remove Check or set ignition and/or cam timing. The above processes will be operated with the sequence of operations of ports in the 2 stroke engine. C $23.16. The kit consists of a screw adapter for the most common pole wheel threads. Goes like this: number of degrees the readings are from top dead center together. So that may be kind of confusing. I don't enjoy math that much, and since this is a one-off project, it was easier to build the pipe, then cut and fit like this. Once you are sure they are lined up, tack the 2 pieces together as shown in Picture 7, then clean up the burnt flux if you are using a flux core welder, and start welding! That means I needed 45 marks on the other side, which worked out to be a mark every 4.8mm. Here's the quick version of how to jet your engine:  Make an educated guess (and guess on the rich or large size). Computer input requirements are indicated for the following software programs: Exhaust & Transfer Ports - TimeArea & BlowDown TA - Input Required: BMEP & RPM + Degree Wheel requirements. TDC is EXACTLY where the needle stops. Loosen the degree wheel retaining nut and rotate the degree Location NRW, Germany. that the pointer must line up with on the degree wheel when the piston is precisely every time will give a racer more consistency and that can be very The BUZZWANGLE Tool is designed to determine the ignition timing and the control angle of a two-stroke engine in a very simple way. They were in the business of manufacturing economical two-stroke motorcycles and stood to profit from changing the two-stroke's image. 71 / 2 = 35.5 degrees. My first attempt was done with an Oxy-Acetlyne torch, mainly because I wanted to practice using it. This is where the Squaring Shears come in handy- its great for the long straight cuts (see Picture 4). Fortunately, You can also remove the cylinder head and attach a small metal bar across Divide the total degrees by 2. Integrated Crank Socket allows for ease of rotating engine assembly and uses interchangeable inserts for … Once you have the cone roughly bent (see Pictures 5 & 6) take some time with a hammer and the Stake Table to pound the cones into shape. Thread starter shakedown; Start date Mar 1, 2009; Status Not open for further replies. it is to set up a degree wheel. The spark occurs when the points open. According to the books, the best way to build the hangers is to use the same metal used for the pipe, but layer it so that it's twice as thick. via the connecting rod, crankshaft position can be accurately described by See Picture 7 & 8. On one side, starting at the widest point of the circle (the diameter) in the direction you want the pipe to bend, cut off a sliver at the angle you want the pipe to go. the procedure because something is wrong. that slides back and forth or up and down, in a cylinder. The rule book explains the procedure well. You can calculate easily and fast the oil quantity by dragging two bars without entering numbers with keyboard. My G45 measured out at 145. Can anyone help instruct me on how to use it? The actual stroke is two times this measurement. on Introduction, helo bro can you pls send me the 2 stroke wizard, 7 years ago 1. The EASY way (Pictures 6-11) one fourth of a turn is 90 degrees. in degrees of crankshaft rotation. On the "zappy-zap" welding- if you are still blowing holes in the metal, you can also weld a spot, jump ahead about 1/4" and weld backwards into the already welded spot. Cut the pipe straight through. See Picture 2.Building the Brackets There are three ports are present in the two stroke cycle engine . adjusting ignition timing. Staff member. The first commercial two-stroke engine involving in-cylinder compression is attributed to Scottish engineer Dugald Clerk, who patented his design in 1881. I hope you have enjoyed this instructable on hand forming an expansion chamber. won't be exact yet, but it will make the next steps easier. 5.0 out of 5 stars 1. But one of the most important things to know is that arc is one of the ways to measure circles. Cut it about six inches long, the length is not critical. It is far easier to hook up a dial indicator to the top of a cylinder than In two-stroke engines, the Thermodynamic cycle will be completed within the one revolution of the crankshaft. Simply attach to crankshaft. They would be the ones who could tell you for sure if it can do that or not! cycle of an engine that allow it to run and make power. the ring(s) from the piston.
