South Bend 9A 9B 9C and 10K lathe gears (14.5 PA, 18DP)

Description

Print The Ones You Need. All Gears Are 3/8" Thick And Have 9/16" Hole Diameter And 1/8" Keyway. The Diametral Pitch Is 18, And The Pressure Angle 14.5 Degrees. Designed In Fusion 360. Why These Sizes? The Collection Includes Several Non Standard Sizes (E.G. 27T). I Use Them As Stud Gears On My South Bend 10K To Cut Metric Threads. For This You Will Need A Metric Conversion Gear (See Below For An Approximation You Can Print), And Some Calculations. Approximation For The Metric Conversion Gear. The Conversion Is A 63T Gear Bolted On The 80T Idler Gear. The 80T Idler Gear Should Come With Most Lathes. The 80/63 Approximation To The Exact 127/100 Conversion Double Gear Is Pretty Good (The Error Is 0.0125% Or 1.5 Thousands Over A Foot). See My Other Printy-Thingy For The 63T Conversion Gear (Whole Or Rim): Https://Www.Thingiverse.Com/Thing:2993608 Take A Look At Mrpete'S Videos Such As Https://Www.Youtube.Com/Watch?V=V6Aq0D1070I These Things Do Last For Hobby Work Or In A Pinch.
