chrome tank 009.jpg
798 viewsThis two part mold is used to cast the lead antomony anode. After casting, the anode is machined; then a machined copper plug is screwed to the top for the alligator clip contact area. The machined anode is located precisely in the center of the liner to give an even amount of chrome on all sides. The diameter of the anode is .750 when chrome plating a liner with a 1.127 ID. This large size anode places the anode close to the cathode (the liner) which makes the plate very straight.Jim Allen

Pistons that differ by .0001 give different piston liner fits585 viewsStarting with the first photograph of the largest piston, notice how a change of .0001 smaller effects where the piston stops in the liner.Jim Allen

dynamometer 028.jpg
rear view showing the load control valve624 viewsThe valve has a scale on the rear of the dyno housing & a pointer on the knurled control knob. The valve can go from full open to full closed when varying load amounts.Jim Allen

DP-350 Digital Panel572 viewsThis digital panel is connected to a calibrated load cell. It reads the applied force in lbs to two decimal points & it is shock mounted. The cost is about $650.00.Jim Allen
torque cradle using Dynamax fun for load1402 viewsThe load is varied by changing the size of the opening to the fan. Notice the air outlets on the circumference of the fan housing directing the escaping air away from the torque cradle. With the craddle locked by the black delrin block, the engines needle is set for maxium rpm. Then the cradle is released, & the swing position of the weight is noted by the pointer assembly. After the engine is stopped, a beam type torque wrench is placed in the nose cone & the entire unit is rotated for the torque amount.Jim Allen
447 viewsBall end blanks & female end blanks before machining. The pieces have a bored ID hole & machined OD, done in one setup for concentricity. Also shown are the 8-32 splined cone point set screws & splined wrenches. Cone point set screws are used in conditions where severe vibration is present. A matching cone shaped seat in the shaft, plus #271 locktite, prevents the set screws from coming loose; unless they are heated.Jim Allen

1106 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
724 viewsThese spring steel washers will prevent any galling of the clamping nut, even when it is tightened with great force.Jim AllenSep 27, 2007
737 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

641 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
654 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
608 viewsThe collet holding fixture is made of #316 stainless steel & is not hardened. Jim AllenSep 27, 2007
588 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
697 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
1011 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
