| Converting pneumatic Biax to electric |

I am in the process of converting the scraper to an electric unit :zap: The main idea is to use a kress spindle to replace the pneumatic motor. I plan to machine down the original spindle so it can be fitted in the collet of the kress, I read that the original speed of the motor was around 20k so the spindle speed of 10k to 29k should be fine. As the spindle is hardened I am wondering what is the best way to cut the end off and turn down the od from 12mm to 10mm (max collet size of spindle is 10mm). I plan to make the adapter from aluminium, one end will be threaded to fit the existing threads on the main body whilst the other will have a split collar that fits on the kress. What do people think? |

Definitely a worthwhile effort if you can marry the two parts. Does the air motor use the typical 4-tooth spline of the electric Biax? |
