Ingredients of Bintsuke?
|
Cooking oil, paraffin, tallow, beeswax, cheesecloth, Rosin.
|
|
|
How to make Bintsuke?
|
Heat cooking oil to boiling. Add rosin and wait until it melts completely. Add beeswax and tallow, stirring until they melt and mix completely. Let mixture cool to approximately 150° F. Add the paraffin and allow it to melt. Soak the cheesecloth strips in the mixture and allow the Bintsuke to cool. Twist or fold the Bintsuke-impregnated cheesecloth into the desired shape for storage. The compound will stiffen during storage but will become flexible when worked by hand.

UNSEATING PROP
|
Pilgrim Nut- Forces hydraulic fluid into nitrile tire pushing ring outward against backing plate. Charleston Gear- Hydraulic ram pushes against strongback seated on Prop Nut Explosives- last resort, permission from NAVSEA 00C5 |
|
|
Rigging the Prop
|
Balance Beam- Transfer straight vertical lift displaced by horizontal component 1/2 beam length. Yard and Stay- Drop Prop. With existing attachements points then stayed out and attached to surface crane, U- shaped tunnels for rigging called lifting tunnels or "Rat Holes" |

|
Seating the Prop
|
Pilgrim Nut- Preferred method, advance the prop. Measures with dial indicator, advance taken from ship prop drawing. Slowly pressurize, take PSI and dial indicator readings at 500 PSI increments. Actual advance is difference between initial and final within +.005"-0.0" if plot not smooth, prop may get caught. |
