While trying to make my Forster DBT base (Inside-Outside deburring tool) an electric powered doohickey with a Dremel tool, it made me aware by freezing up in rotation it was spinning too fast from heat friction...and it locked up.
Yes, I know ball-bearings are the way to go, but you can't put them in the DBT base.
Went to a lot of trouble making an adapter that would screw onto the threads that once held the knurled knob handle. This adapter worked very well connecting up the DBT base and the Dremel tool rested on a little plastic stand with a hose clamp.
OK, go to plan B. Remove Dremel tool, and find that Skill Twist cordless screwdriver I never use anymore. It had been put away in my tool box about 7 - 10 years ago, and I found the battery is deader than a mackeral and won't take a re-charge.
That screwdriver will be getting a new batterey as soon as I can locate a place that has them, maybe Ace hardware.
Already made another adapter on my mini-lathe to work in the Skill Twist cordless screwdriver, that will connect the DBT base to batterey charged screwdrive...which rpms turn at a more sedate rotation that can be operated by a flick of a finger teater-toter switch that is forward and reverse.
If you ever decide to play around with this stuff, I'm an expert on adapter making and can help.
