Need Help!- Convert Pnuematic Speed and Brake to Manual

[PaulDSS]

I have a Bridgeport Series 2 CNC mill that I am in the process of updating to use in my home shop. This machine has a pneumatic speed and brake controller. Maybe this was a nice feature in it's day but I would rather have a manual speed selector wheel and a manual brake.

Do you know if it is possible to convert these pneumatic controls to a manual control. It looks like there are so many similarities between the various Bridgeport models that it might be possible to purchase a few parts from a different model to convert it.

Let me know if you have any sugestions about what parts I would need or if this is even possible.

I did it on my series one head. The basic config. is the same as the manual head. I just removed the brake cylinder assy and put on the handle from a manual head. The speed control air motor and the complete speed dial assembly removed and was replaced by the manual machine parts. Of course the series2 might be differrent. I would compare yours to a series 2 manual head. A exploded parts diagram would be helpfull.
