paint spraying equipment 006.jpg
Typical dryers180 viewsThree sets of dryers are used when spraying epoxy paints. One set at the compressor tank & these two sets just before the spray gun. The set on the bottom, with the gage, are actually fastened directly to the spray gun handle. Even very small amounts of moisture can cause clear epoxy paints to become dull & not cure properly. Heated epoxy paints should become tack free several minutes after spraying even though full cure may take 24 hours.Jim Allen
263 viewsThis is the tapered collets internal seat & clamp. It also fastens to the flywheel face with two 6-32 bolts. It is located with a very tigh fit (.0002 interference) on the steel stub on the flywheel's face.Jim Allen
264 viewsPicking up a rough center hole location with the piece held in the milling machine vise. Picture should have been rotated clockwise 90 degrees!Jim Allen

Protective shroud474 viewsThis .375 thick protective shroud is necessary because the Dynamax fan is limited to 32,000 rpm. It is mounted to the rear shaft bearing block & rotates with that same block. It serves an additional purpose of preventing the fan blast from hitting the torque craddle. Notice the air outlets on the outer, rear dia of the fan shroud. Also notice the .032 thick pointer, left of the plastic shield, which is fastened to & rotates with the main shaft. This is used to determine torque amounts. A load cell & digital readout will be added in the future. Jim Allen
liners & pistons 012.jpg
Machined pistons & K-67 stock piston659 viewsThe four pistons on the left are machined from RSP Technology 30 % silicon alluminum alloy # RSA 444. Diamond tooling including drills, end mills, boring bars, & lathe tool bits make it possible to achieve a very smooth finish. The piston on the right is a stock piston.Jim Allen

Spray gun metal canister192 viewsThe bottom of the metal canister is cut of, to allow a visual observation of the amount of paint remaining. It also provides a safety shield in the event the siphon bleed becomes clogged or if the siphon pressure valve is in the wrong position. Epoxy paints are sprayed with siphon feed at 5 to 8 psi & 20 cf/m of air. A GLASS JAR WILL EXPLODE IF IT IS USED WITH PRESSURE FEED OR IF THE SIPHON BLEED BECOMES CLOGGED! This has NEVER happened in 28 years of use, because the spray gun is always carefully cleaned & inspected after each use.Jim Allen
gas tank 015.jpg
Tank & baffle435 viewsThe tank baffle has an opening at the top only. Because of its angle, fuel will pass over the top whenever the boat is turned to the right. Turning the boat to the left will not allow any fuel to pass except when the tank is full. The fuel line (located in the lower left rear corner) & the pressure line (located in the upper right rear corner) are also welded & soldered into

crankcase, crankshaft, & piston fixtures 011.jpg
Crankcase boring fixture815 viewsNotice that the clamps are designed to be below the area of the crankcase where the round profilling must be done.Jim Allen
torque cradle 011.jpg
Torque cradle front end706 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

650 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
553 viewsThese spring steel washers will prevent any galling of the clamping nut, even when it is tightened with great force.Jim AllenSep 27, 2007
572 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
371 viewsJim AllenSep 27, 2007
476 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
486 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
447 viewsThe collet holding fixture is made of #316 stainless steel & is not hardened. Jim AllenSep 27, 2007
429 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
533 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
791 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
