EACH ORDER
COMES WITH A PHOTOCOPY OF THE
CENTER DISTANCE CHEAT SHEET
THAT CAN BE SEEN IN THE PICTURES !
WE HAVE USED SEVERAL OF THESE GEARS ON OUR PROJECTS AND FOUND THAT THEY ARE VERY
USER FRIENDLY.
THE TEETH ARE LARGE WHICH MAKES MATING THEM TOGETHER EASY BECAUSE THERE IS MORE ROOM FOR ERROR. WE CHOSE THE CORRECT CENTER DISTANCE FROM THE SHEET AND THEN ADDED .020" OF EXTRA SPACING FOR SOME "BREATHING ROOM". THIS EXTRA SPACE ENSURES THAT THE GEARS WILL TURN FREELY AND NOT BIND OR BE TIGHT.
SEE PICTURES THAT SHOW SOLDER TECHNIQUE TO ATTACH A HUB TO ONE OF THE GEARS. THIS IS A STANDARD NICKEL PLATED BRASS SHAFT COLLAR FROM A HOBBY SHOP. THESE PICS ALSO SHOW A SOLDERED PINION ON A BRASS SHAFT.
WE HAVE OVER 11,000 OF THESE SPUR GEARS FROM MASSACHUSETTS ESTATE SALE. ALL GEARS ARE THE SAME PITCH AND PRESSURE ANGLE.  16 PITCH AND 20 DEGREE PRESSURE ANGLE. THE SMALLER SIZES (5, 6, AND 7 TOOTH) HAVE 1/8" BORES AND THE REST HAVE 1/4" BORES.
THE 1/16" THICKNESS FROM 15 TOOTH AND UP HAVE A SMALL SLOT FOR A CROSS PIN TO LOCK IT TO THE SHAFT WITHOUT SOLDER.
PLEASE LOOK CLOSELY AND YOU WILL SEE THAT UNLIKE AMAZON WE USE
REAL PICTURES
OF EACH TOOTH COUNT AND NOT JUST A STOCK PHOTO FOR ALL SIZES !
NO DROP SHIPPING ! EVERYTHING THAT YOU SEE, WE HAVE ! !
THIS IS A MULTIPLE CHOICE LISTING. YOU MUST FIRST CHOOSE THE FACE WIDTH AND THEN CHOOSE THE TOOTH COUNT. THEN YOU SELECT YOUR QUANTITY.
THESE GEARS CAME WITH SEVERAL SERVO GEARBOXES. WE HAVE INCLUDED SOME PICTURES OF THESE IN THE LISTING TO SHOW HOW THESE CAN BE USED. PLEASE NOTE THAT THE GEARBOXES ARE NOT PART OF THE LISTING.
THE THICKER 1/8" WIDTH GEARS ARE DESIGNED TO BE SOLDERED TO BRASS SHAFT OR ATTACHED TO A LOCKING HUB TO DRIVE THE SHAFT.
THE THINNER 1/16" WIDTH GEARS CAN BE SOLDERED OR USE THE INCLUDED SHAFT PIN. ANY GEAR THAT HAS A SLOT COMES WITH A PIN. THE PIN IS INSERTED INTO THE SHAFT AND THEN THE GEAR IS SANDWICHED BETWEEN 2 SHAFT COLLARS.
THE PACKAGE OF PINS THAT CAME WITH THIS LOAD OF GEARS HAS 12,000 PIECES. WE ESTIMATE THAT THIS IS ALSO THE QUANTITY OF THE GEARS. WE STILL HAVE THOUSANDS TO CATALOG BEFORE WE CAN UPDATE THE QUANTITIES.
IF THE QUANTITY SAYS WE HAVE 7 THEN WE HAVE 7
