dynamometer 004.jpg
dyno load control knob809 viewsThis knob rotates a very precisely machined stainless steel barrel type valve that is centered on the center line of the rotor contained inside. It has an o ring seal & a teflon based locking screw to prevent rotation during dyno pulls.Jim Allen

Forming die pieces278 viewsThe two pieces on the left are dowel pinned & screwed to the piece on the right. Trapped in between is the tin steel piece to be formed. Jim Allen
Deep-Groove Ball Bearing 014.jpg
766 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
connecting rod 024.jpg
729 viewsThe connecting rod grinding fixture holds the rod with the small clamps at each end & two 2-56 set screws in the middle. The locating pins are removed through the bottom of the fixture.Jim Allen

crankshaft machining fixture513 viewsThis fixture used the hole on the left hand side to machine the crankshaft counter balance area. The hole in the right side was used to grind the crank pin hole, after mounting to the lathe face plate with dowel pins.Jim Allen

Deep-Groove Ball Bearing 015.jpg
706 viewsThese hardened & ground gages allow precise grinding of the bearing bores to the correct size. A .0008 interference fit is used on the rear main & a .0005 on the front main in all assemblies made. Each gage is .0002 under nominal size to insure proper bearing fit. Only custom assembled high clearance ceramic bearings can be used at these interference fits when using a hardened steel front end!Jim Allen

950 viewsSide view of the geared twins. The engines fire alternately & with the gear wine they sound like a turbine. Geared twins set up this way require that both motors turn clockwise. Reverse rotation inverted drum valves made this possible.Jim Allen

K & E drafting table799 viewsAll boats, including kit boats, that I build, have full size prints showing complete hardware details. Some details include; designed running attitude with water line; exact engine position; locations of skid fin, rudder & strut; location of all radio parts; etc. This allows modifications to be done easily & it allows precise location of necessary holes.Jim Allen
548 viewsThis fixture is used to machine & bend throttle arms.Jim Allen

708 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
599 viewsThese spring steel washers will prevent any galling of the clamping nut, even when it is tightened with great force.Jim AllenSep 27, 2007
619 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
410 viewsJim AllenSep 27, 2007
521 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
531 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
489 viewsThe collet holding fixture is made of #316 stainless steel & is not hardened. Jim AllenSep 27, 2007
469 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
579 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
858 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
