Carbon fiber cowling in place on the hull450 viewsThe solid carbon fiber rod does not go completly into the high modulus sponson tube, but ends 1.750 in from the inside of the sponson. This allows the sponson tube to shear off easily in the event of a collision. After milling out the damaged tube in a jig, new tubes are glued in; also done in a jig. Jim Allen

rear view of dyno housing1234 viewsThe long knurled knob is the load control valve. It is pre-set before the beginning of the dyno pull. The two smaller black knobs control incomming water to the engine & incomming water to the dyno reservoir. Incomming water to the engine is metered at the outlet to control engine temperature. Incomming water to the dyno reservoir is adjusted to maintain a completely full reservoir during dyno pulls. This ensures that there is no change in the pre-set load amount due to a change in the water height in the reservoir.Jim Allen

The anvil with the shims in place295 viewsIn the next two photos the .008 shims are visible at both ends & at both sides.Jim Allen
roller rod bottom end1665 viewsThe "I" beam connecting rod; through hardened; tempered; with both holes align ground; & with no bushing in the upper end, allowing the rod to be lengthened to a maxium length of 1.741 center to center. The AISI S-7 shock resisting tool steel used, after hardening & tempering, has a 315,00 lbs/square in tensile strength; a 210,00 lbs/square in yield strength; is 58 Rc hardness & has a C-notch Charpy impact number of 224 ft. lbs. The rod has a .250 in dia. wrist pin with the upper outter dia. of the rod at .360 in. The connecting rod is .030 thick in the middle of the "I" beam with 16 caged rollers; 2 in each window. The maxium clearance in the bottom end is .0003 in; in top end .0001 in. The connecting rod runs forever at 32,000 to 35,000 rpm with no wear & a maxium of 8% oil. The connecting rod is guided in the upper end between the piston bosses with .005 in total clearance. The retainer, with two rollers per window, is made of full hard (Rc-60), C-350 Maraging steel. Its tensile strength is 350,000 psi making it the strongest part in the motor. Notice the two .3125 dia carbide slugs added to the crankshaft counter balance, which gives 33% of the total weight of the piston, pin, & connecting rod on the crankshaft coiunter balance.Jim Allen

Inside view of jar cap modification172 viewsThe siphon air bleed hole can be clearly seen at the bottom of the aluminum ring. The metal pickup tube has been cut & rebent for the proper location in the glass jars used. A 100 mesh stainless filter is fastened to the end of the tube for final filtering.Jim Allen

749 viewsThe pitching blocks use dowel pins for alignment. When the pitching blocks are closed in a vise, the propeller blades are held securely for pitching up or down. On the left are pitching blocks used to bend 2170 blades; in the middle V-967 blades; on the right are pitching block cavaties.Jim Allen

mufflers & stinger reducing devices638 viewsSmall reductions in the stinger dia will raise the engines head temperature & HP rapidly. The same thing happens when the stinger is made longer, but the head temperature & HP rise slowly. Mufflers which reduced the DB reading by five had the least effect on HP readings. Mufflers that reduced the DB reading by ten reduced HP, but brought engine noise down to 80 DB at 50 ft.Jim Allen
torque cradle 004.jpg
Adjustable dyno weight616 viewsThe only purpose of the weight is to control the amount the cradle will swing during dyno puls. I have several weights from 12 ozs to 2 lbs 10 ozs. All can be adjusted on the threaded shaft. These weights have no effect on the amount of torque developed or the measurement of that torque. Jim Allen

642 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
545 viewsThese spring steel washers will prevent any galling of the clamping nut, even when it is tightened with great force.Jim AllenSep 27, 2007
565 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
364 viewsJim AllenSep 27, 2007
468 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
479 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
443 viewsThe collet holding fixture is made of #316 stainless steel & is not hardened. Jim AllenSep 27, 2007
423 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
527 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
785 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
