connecting rod 033.jpg
Phase 2 tangent radius dresser727 viewsA tangent radius dresser will put the correct radius & tangent line in any aluminum oxide grinding wheel. This operation is done on the surface grinder. This dresser formed the radius on a wheel used to grind the ends of the 16 (M-2 steel), .0627 reamer blanks that are used for connecting rod rollers.It also dressed a wheel for the ball end universal part tool bit, used in the lathe.Jim Allen

torque cradle 014.jpg
Top view of black delrin clamp block & throttle control831 viewsThe throttle control is designed for very rapid opening & closing; a necessary feature when testing piped engines. Engines that are tunned properly, will pipe up instantly from 12,000 to 32,000 rpm, even after long periods of low throttle operation. This fearure is helped greatly by the automatic fuel metering carburetor.Jim Allen

fuel metering carburetors620 viewsAll carburetors tested have been automatic fuel metering barrel types. All have aluminum bodies & stainless steel inner parts. Diameters tested are .475; .513; .625; & .750. The newest carburetors use a needle valve that is not tapered. This feature eliminates the condition that takes place when leaning tapered needles that are not concentric; the needle goes lean, then rich, only to go overlean suddenly.Jim Allen
jig grinder 001.jpg
Yuasa jig-grinder797 viewsThis Yuasa Accu-Jig-Grinder #525-200 contains an air turbine & rotates at 120,000 rpm with 80 lbs of air. It uses borazon & diamond pins for small hole grinding & can be mounted in the lathe or the milling machine.Jim Allen
torque cradle loading devices 011.jpg
Five loading devices728 viewsFive loading devices will allow one thousand rpm increments from 32,000 to 36,00 rpm. This will be accomplished by reducing the diameter of each blade. Jim Allen

chrome tank 009.jpg
668 viewsThis two part mold is used to cast the lead antomony anode. After casting, the anode is machined; then a machined copper plug is screwed to the top for the alligator clip contact area. The machined anode is located precisely in the center of the liner to give an even amount of chrome on all sides. The diameter of the anode is .750 when chrome plating a liner with a 1.127 ID. This large size anode places the anode close to the cathode (the liner) which makes the plate very straight.Jim Allen
753 viewsAll the internal parts of the carburetor are made of 303 stainless. The carburetor meters fuel automatically as the barrel is closed & has a .0625 dia. stop pin in the outside of the rotating barrel which engages the machined circular grove in the .032 thick side plate. This feature controls the full open & closed positions. The needle valves have precision ground tapers & are made of 52100 full hard steel gage pins. The needle valve retainer spring is made of fully hardened beryllium copper. A new design needle valve is being built which will eliminate the problems associated with non-concentric tapered needle valves.Jim Allen
pit box 001.jpg
Pit box415 viewsThis pit box contains all the necessary items to start the engine. There is no battery for an electric starter because the engine is started with a pull chord. In the photo beneath the box are some typical pull chords made of 1/8 dia nylon & kevlar braided ropes. The glow plug cables are very fine stranded 12 gage copper wire. Their ends are staggered to prevent accidental contact & a insulator is connected between them during transport. This is necessary because the glow plug battery is a 10 amp hour nickel cadium wet cell. It easily lights any glow plug used, including a Novi Rossi # 9. The aliminum plate holds various types of glow plugs including tappered seat & standard types.Jim Allen

627 viewsCompleted pieces are all interchangeable & after mounting to the flywheel are within +-.0002 concentricity 1.000 in from the split collets face. The same type of a flanged piece with six mounting holes is made when I set up ball and pin universals for solid shaft applications. When using the solid shaft method the thrust is driven up the entire shaft into the engine by using hardened thrust washers between the ball ends & there sloted ends. Jim AllenSep 27, 2007
535 viewsThese spring steel washers will prevent any galling of the clamping nut, even when it is tightened with great force.Jim AllenSep 27, 2007
555 viewsMachine an arbor; fasten pieces securely; machine the OD with carbide. Finished washers have no burs on the OD or ID & are very precise.Jim AllenSep 27, 2007
355 viewsJim AllenSep 27, 2007
460 viewsAfter clamping .010 thick spring steel pieces between two aluminum pieces, they are machined square to a convienent size. Boring with carbide gives a clean hole without burs. Jim AllenSep 27, 2007
471 viewsThis photo shows the locking nut being singled pointed internally. This piece does not have to be hardened because it will ride against the spring steel washer when tightening the split collet. It is made of #316 stainless steel.Jim AllenSep 27, 2007
434 viewsThe collet holding fixture is made of #316 stainless steel & is not hardened. Jim AllenSep 27, 2007
414 viewsThe split collets are ground internally while being held in the fixture directly above them. External grinding was proved to be un-necessary.Jim AllenSep 27, 2007
516 viewsThis photo shows the back ends of the split collets being ground square to their ID's. This is done in a Suburban Tool Master-Grind. (+-.00005 spindle runout) The split collets are wrung onto a hardened indicated gage pin for this operation.Jim AllenSep 27, 2007
774 viewsTwo 6-32 SHCS, a precisely machined steel hub on the flywheel face (.5002 OD) & a flange on the tapered sleeve which has a 1.125 in OD (.5000 ID), ensures positive location of the tapered sleeve each time it is mounted. The hub is #316 stainless steel & is shrunk into the flywheel before final machining. Notice the six bolt hole pattern used on the tapered sleeve's flange. This feature allows automatic positioning of the propeller to a horizontal position if the engine should stop suddenly at wide open throttle & prevents the hull from diving! It is used on solid drive shaft setups.Jim AllenSep 27, 2007
