Fuel tank in SG 80 hull521 viewsEnough room has been provided to allow .125 thick foam to be placed on the bottom & both sides of the tank.Jim Allen

845 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 Allen

Deep-Groove Ball Bearing 014.jpg
817 viewsThe sleeve, which fits over the crankshaft, fastens both inner races of both bearings mechanically to the crankshaft. The front end seal is machined onto that same sleeve. Crankshaft endplay is set at .003 to .004 with machined spring steel shim washers to be shown. Even at elevated running temperatures, the end play remains the same, because all parts; the crankshaft; the sleeve; the shims; the front end; & the bearing races; ARE ALL MADE OF STEEL! This system also works with all metal bearings, but CERAMICS WILL RUN FASTER, LONGER!Jim Allen
dynamometer 002.jpg
rear view of dyno housing925 viewsThis knurled knob controls a valve which allows infinitely variable loads (from full open to full closed) to be applied to the engine being tested. Repeated dyno pulls tells me where any engine makes its peak HP. There is only point where this takes place; where the torque curve & the RPM curve cross one another.Jim Allen

736 viewsFinished rollers & crank pins, both made from full hard (63 Rockwell C) M-2 steel reamer blanks. The rollers are .0627 dia. X .250 length with a .0313 radius on both ends. The radius is ground on each roller end after cutting the roller to length. Full contact length of each roller is .1875. The crank pins are .3283 dia. with the driving pin for the bell valve ground on one end. The crank pins are a .0013 interference fit in a ground hole in the through hardened crankshaft. These crank pins never come out or break & the wear is very low because of the large diameter!!Jim Allen

705 viewsThese spring steel washers will prevent any galling of the clamping nut, even when it is tightened with great force.Jim AllenSep 27, 2007

720 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

625 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

638 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

591 viewsThe collet holding fixture is made of #316 stainless steel & is not hardened. Jim AllenSep 27, 2007

567 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

682 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

988 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
