gas tank 017.jpg
Fuel tank in SG 80 hull467 viewsEnough room has been provided to allow .125 thick foam to be placed on the bottom & both sides of the tank.Jim Allen
crankcase, crankshaft, & piston fixtures 006.jpg
Precision face plate with crankcase boring fixture mounted944 viewsWhen mounted in this position, the front end bore is done. Rotating the fixture 90 deg allows the cylinder bore to be done. When doing the cylinder bore the brass weight is not used. Custom made, .750 in dia, carbide tipped, boring bars are used to bore the crank shaft & cylinder bores.Jim Allen

The dyno consists of three main blocks500 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

The anvil with the shims in place, turned 90 deg308 viewsTwo of the four shims used can be seen at the top & bottom of the anvil in this photo.Jim Allen
501 viewsThis fixture is used to square the side flange & cut the "V" in the fuel metering device.Jim Allen
connecting rod 005.jpg
Phase 2 rotary table & Yuasa rotary table686 viewsAn accurate rotary table is required to profile the outside of a connecting rod & machine the I-beam center section. It is also used to profile the outside of an engine crankcase; machine all piston internals; etc. Rotary tables come in many different diameters with different veniers. A 10 second venier will do many jobs easily.Jim Allen

774 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
dynamometer 018.jpg
DP-350 Digital Panel513 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
hydraulic dynamometer956 viewsThe dyno has an infinitely variable load by controlling the amount of water in the housing. This is done with a valve in the base of the dyno housing. The valves knurled knob can be seen at the bottom rear of the dyno housing. Jim Allen

659 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
559 viewsThese spring steel washers will prevent any galling of the clamping nut, even when it is tightened with great force.Jim AllenSep 27, 2007
579 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
377 viewsJim AllenSep 27, 2007
482 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
492 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
453 viewsThe collet holding fixture is made of #316 stainless steel & is not hardened. Jim AllenSep 27, 2007
435 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
541 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
801 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
