424 viewsWhen all the pieces are assembled together the indicator reading is within +- .0001.Jim Allen
P7160005.JPG
1033 viewsAll the back ends of the engine universals are machined first with holes for 6-32 screws. All pieces are then mounted on a machined arbor for cutting of the ball end. Each ball is indicated in a fixture to insure the precise location of the drive pin is centered. All male & female pieces are interchangeable with a concentricity of +-.0002.Jim Allen

Test fitting508 viewsThe "T" shaped blades should not fit losely! All the inside corners on the "T" shaped blades & the "T" shaped slots are machined with a radius to help eliminate any stress points.Jim Allen

The dyno consists of three main blocks541 viewsThe three main blocks; the engine mount & the two fan shaft bearing blocks are all the same width. All three main shaft holes are aligned bored in these blocks at the same time. The fan shaft bearing holes are also bored at the same time. These three blocks & the main shaft are set up on a surface plate to ensure alignment. After alignment the three blocks are locked into position while still on the surface plate. Notice the split in the engine mount block that allows it to be clamped to the main shaft. The fan shaft bearing blocks are clamped in the same manner. All blocks have jack screws to make positioning on the main shaft easy.Jim Allen

front view of the dyno housing615 viewsAll pieces are machined with .0001 precision. The front & back bearing mounts are concentric within .0001 also. The ball of the universal (.3125 dia) & the center shaft (O-1 tool steel) are machined as one piece to ensure concentricity. Notice the blue colored ball end (spring temper) which allows a .001 interference fit of the 4mm (.1575 dowel pin), without splitting the ball. This pin NEVER comes out & can be replaced when worn. This procedure is done in a fixture.

some tuned pipes that have been tested615 viewsThe top pipe is a Rossi 1.05 duct fan pipe. The second pipe down is a carbon fiber pipe. I could not solve the problem of seperation at the head pipe area. High temperature cynate ester resin was used which could stand 750 deg F temperature. The bottom, steel rolled pipe, was used in the 38,000 rpm engine test.Jim Allen

835 viewsThis picture shows machined spring steel shims made using the same method used to make crankcase shims or head shims. On the left is the crankshaft sleeve that sits between both inner races with the correct thickness shim to give .003 to .004 end play. Jim Allen

405 viewsThe aluminum piece on the left will become a taper master. It can be used to quickly & accurately re-set the compound for cutting tapers. Jim Allen
torque cradle 018.jpg
Dedicated table for torque cradle774 viewsIn the bottom of the picture, mounted on the table, there is a flow gage & a water control valve that are used to control engine temperature. Also notice the two black, round delrin pieces, mounted to the table top. They hold the dyno feet & prevent movement of the dyno during dyno pulls.Jim Allen

834 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

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

710 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

616 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

628 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

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

558 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
cable_collet_clamps_050.jpg
669 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

974 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
