Welcome to unsupported upgrades! Development of this spindle cartridge definitely took longer than expected due to adding another kid to the clan, pretty crazy times at the office…and a global health pandemic. I ended up doing a total of three revisions of the preloaded dual angular contact spindle design I am currently running on my Nomad 883 Pro before I was happy with it. This spindle design has a larger diameter spindle shaft and bearings than stock machine as well as frictionless dual labyrinth seals. The three I’ve built up so far have been super smooth but also very stiff, quite happy with this ‘best and final’ design. This is a direct stock spindle replacement, 100% bolt on with no change of clearances and takes less than 15 minutes with basic tools.
- 10mm diameter spindle shaft up from 8mm on stock design, should be ~56% stiffness improvement if I can do math correctly on Saturday mornings
- 7000 sized angular contact bearings
- Six custom machined parts per spindle; housing, spindle shaft, two inner and two outer labyrinth seals
I’m offering these at $300 each shipped and a handful have already sold to people who have offered to do product reviews if you’re on the fence. I anticipate people being pretty stoked with the improvement in material removal rates but mostly the reduction in sound levels cutting harder materials.
Send me a DM if you are interested!
