576 viewsThese jig bored engine mounts locate the concentrically ground (inside & outside) full hard (O-1 tool steel) front ends at the correct gear locations. The three holes are bored to the same size as the ground front ends, at the same time, in the same setup, insuring squareness in both axes at the same time. The front ends are easily slipped into these holes because of the two jack screws located between the four flat head clamp screws seen in the top photo. The eight visible through holes which allow fastening of the front ends, the crankcases & mount together, plus the four clamp screws, give one very rigid unit when all the alloy steel screws are tightened to 50 in lbs of torque.

Torque cradle front end805 viewsThe 1.000 in dia main shaft rotates in two Barden, 25 mm (.9843) X 47 mm (1.8504), ABEC-7 bearings, with precision machined riveted aluminum cages. The ground shoulder at both ends of this shaft allow the main shaft assembly to be preloaded. Notice at the base of the front main shaft bearing housing how it is keyed to the base. It is also doweled pinned for easy re-location when assembling the unit.Jim Allen
chrome tank 001.jpg
984 viewsA complete chroming tank with heaters. The chrome tank is maintained at 130 deg. F. & is run at a current density of 3 amps/sq. in. The total current required for the brass holding fixture & the liner is 24 amps. The brass holding fixture prevents the buildup of chrome on the top & bottom of the liner. This build up takes place on the fixture & is removed afterwards with a warm 50% solution of HLC acid. At a current density of 3 amps/sq.in., .0012 in of chrome/side/hr. will be deposited. In 2 to 2.5 hrs, a total of .0024+ in of chrome should be deposited on the liner wall. If done properly, this simple bath will deposit smooth chrome with a hardness of 1,000 Vickers. Carbide tooling WILL NOT cut even 900 vickers chrome! Jim Allen

565 viewsNotice that the lathe's ways, which are hardened & ground, have been covered to prevent any small grinding particles from being trapped beneath the carriage.Jim Allen

686 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 Allen

850 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

1038 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

629 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

642 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

572 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

993 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
