    I know how to do the rest, but I can't for the life of me work out how to drill the counter gear to make full floating gear without damaging the gear. Any one could give me some pointers?

    I can do that, but what I want is to remove the entire middle section. I want to know how to do that without damaging the gear.

    Yes like that, but all the way through, I want to mount the gear on ball bearing only. I need to try find a routing bit rather than a drill bit.

    I found this from one of the build guides I was looking at, but can't seem to find anything like it in the UK. http://www.zoukei.jp/product/1587.php

    Would be very handy, not just for routing the gear centers, but for making the suspension upright in the FISS build.


    Edit: Ok, worked out how I can do it and get it to 6mm. Could still use something like a vice or something to hold the gear though.

    I'm thinking I might just get one of those cheap chinese lathes for like £30, that should be good enough for tire trimming and gear hollowing.

    IMG_1876.JPG just take your time and measure a lot with calipers. i screwed up quite a few gears before i successfully made something usable. centering the hole is the hardest part in my opinion

    Another question.

    20170722_161834.jpg

    I was thinking of doing this with counter gear too, but this is for a wheel mount. Now I can get the 6mm bearing into this rubber pipe, but then it won't fit into the wheel mount, same issue vice versa, I can fit the pipe in the wheel mount, but then can't fit the 6mm bearing. Any ideas how to trim down the rubber? I don't want to trim the plastic, as that's already thin as it is.
    I have tried taking a drill to it, but is just gets stuck to the shape of the flutes on the drill bit.

    Help...

    Btw, this is a part I want to make for the FISS v.2
