I was thinking of making a helicol idler gear with timkin bearings like the link below but helicol
out of an existing gear
Purpose to eliminate the idler washers
So what do you think

Ah, you want one like this then? 
(this one belongs to justminis). KG Engineering in Melbourne made it. Company now gone kaput, but hey, it's possible to do. I suspect they made a new gear though, not machined out an existing idler. |

Hi Bernard KG did make a new gear for that set up. My first attempt (1990) was with an original gear machined to suit the timken set up. It worked under a 1380 for quite a while but the centre step in the gear for the bearing races was too thin (my bad) and did break. The KG gear has a substantial centre step. While I have not done another original gear, believe it is entirely possible to use an original gear provided the centre step is sufficient. Steve |

The other alternative is to use a std gear and shaft. Machine the shaft down to 5/8" and fit the taper roller outers to the caseings. The brg in the flywheel side is in a fixed postion but the one in the gear box case has 3 5mm grub screws that push on the outer to give the correct pre-load for the brgs.. With the brgs further apart the whole assembly will take more load and the brgs have less twisting load on them. |
