Ammco Phenolic Bull Gears" for 1940's Ammco and Delta shapers.


 We have about 25 (2-14-2016) phenolic bull gears for Ammco and Delta metal shapers patterned from original gears. The material is the same Grade C phenolic and the attachement inserts are CNC machined from 12L14 steel. The blanks were made and sent to a gear cutting business for the helical teeth to be cut. This is our third run of these gears and we have never gotten a complaint, however we will refund your money if the gear you purchased does not meet your needs and is returned in good unmarked condition.

The price reflects the original replacement cost from an invoice scan from 1948 or 49. That was $14.35 and run through an inflation calculator we get $158.38 (CPI Inflation Calculator).

 We are selling them for $158.00.

Replacement Ammco Shaper bull gear - $158 


From my fourth run of Ammco bull gears over many years, made to original specifications of grade C phenolic with steel inserts for the 1/4-20 slide mounting screws pressed in. The helical teeth were hobbed by a dedicated gear making business. The two small stop pin holes are drilled and two pins included for the installer to drive in place.
Money back return for undamaged gear. Gears sent via USPS flat rate, the cost is included in the price.
Payment via paypal, please contact me over CL mailer and I'll send back the email to send the paypal funds to. If you don't have paypal say so and I will send the postal address to send a postal money order to.
Edit; The price was raised to $158 each because of increases in the costs of materials and production. See first two photos.

As of today we also offer a complete final drive set; (See third and fourth photo's) this bull gear, the mating pinion gear made of steel, the pinion gear shaft with new bronze bushings and the pinion gear pre-drilled and taper reamed for the taper pin. All of the above as per an original sample for $350. Same money back guarantee. Note; the taper pin in the pinion gear is lightly tapped in place, it will need to be driven in so equal amounts project from each side by the installer while the shaft and gear are within the column.
Thank you.
