Steerable Nose Gear 3/32" 1/2A size

thingiverse

If you're like me then you're heartbroken that it's nearly impossible to find steerable nose gear in NON metric sizes now. Carl Goldberg stopped selling the 1/8" steerable nose gear a long time ago. (I'm currently working on a 3D printed replacement) and Dubro seems to have stopped selling my beloved #234 1/2A sized 3/32" steerable nose gear. I only have three packages of the Dubro #234 gear left so I decided to 3D print some standby kits. The nose gear bearing only looks like the Dubro part. It's sized to meet my needs. I also never really liked the Dubro steering arm so I took a Goldberg 1/8" arm design and sized it to fit my needs. I much preferred the offset arm on the Goldberg part. I'm very happy with the outcome. Printer setup and accuracy are of EXTREME IMPORTANCE on the steering arm or you'll be very unhappy with the results. For most holes you can just drill them out to final size but the arm is sized for a 3/32" wheel collar and the opening is a needed interference fit of 6.35 mm o.d.. If you get it right you should need to use pliers or a vise to push the wheel collar in place WITHOUT splitting the sides out. It MUST be tight so your steering stays accurate.Also you MUST USE supports when printing the steering arm!! Of course you'll have to bend up your own gear wire so you're on your own there. There are lots of tools available out there to help you get that done. I included .stl files of the "kit" as well as both parts in separate .stl files for your convenience should you want them that way..
