  • Quote: Same here, except I went one step farther. I also got the reinforced black rod guides. To get even more consistent feel, I also drilled a hole in the plastic piece of the top cap.
    Part number for these and the clear o-rings please.

    Thanks

    For 64 pitch I like the Axon spur gears
    For 48 pitch I like the 3Racing spur gears
    I haven't tried the 48 pitch on the 419x but I think the it's thin enough to fit between the center pulleys ?
    Just my 2$

    My problem with 48p is getting down to 3.2 fdr. It's been difficult to find a brand that has teeth at around 65 that also have the right fit for the pulley.
  • Robinson makes a 66t 48p spur gear and hirosaka makes a 65t spur that is very thin...
  • Quote: Robinson makes a 66t 48p spur gear and hirosaka makes a 65t spur that is very thin...
    Yes but the Robinson spur is too thick. Kimbrough spur gears have the wrong drill hole pattern. I ordered a 69T for the serpent cars. I assume its made by Axon.
  • Then the hirosaka spur will be best at 3mm thickness. It might be hard to find...
  • Has anyone try the Arrowmax Spur Gear?
    Can buy some 48dp with 78 teeth.
