chrome tank 002.jpg
672 viewsA Simpson DC amp meter & volt meter with all hook up wires plus on-off switch. I have two of these also to help speed up the chroming process.Jim Allen
366 viewsA .00005 indicator tells me the piece will repeat within .0001 when mounted in a precision collet.Jim Allen

Tin steel end pieces298 viewsThese .008 thick tin steel pieces have been pre-drilled in a jig. The holes make it possible to hold the metal for the forming process.Jim Allen
343 viewsAfter a rough setting of the compound, repeated cutting & indicating brings the piece to the exact measurement.Jim Allen
liners & pistons 015.jpg
552 viewsNotice the piston is higher up in the liner when its OD is .0001 smaller. The top taper is the same as the first piece.Jim Allen
.90 & 1.0 cu in motors1592 viewsTwo motors with aluminum crankcases & one with steel. All .90 & 1.0 cu in motors have a .902 stroke.Jim Allen

Sticth model MT-1A laser tachometer512 viewsThis digital laser tach; comes with a certificate of calibration; can read 5 ft from the reflector; reads from 6 to 99,999 rpm; has a measuring accuracy of +/-0.006%; has several memory functions; updates the reading each second; & has many other features. It is the ultimate non-contact type of tachometer. The reading seen in the picture is the result of pointing the tach at a neon bulb.Jim Allen
.15 bell valve 006.jpg
688 viewsThe .15 hanger piston assembly, requires very precise machining; but gives extremely low reciprocating weight. No piston bosses; part of the upper end of the rod eliminated; a very short wrist pin; & three windows in the piston make for a very light weight assembly.Jim Allen

902 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
709 viewsThese spring steel washers will prevent any galling of the clamping nut, even when it is tightened with great force.Jim AllenSep 27, 2007
724 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
515 viewsJim AllenSep 27, 2007
629 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
642 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
595 viewsThe collet holding fixture is made of #316 stainless steel & is not hardened. Jim AllenSep 27, 2007
572 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
686 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
994 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
