It's the Makita............."FLEET!!"....and a couple others
Conversions. At left is an old 19V Nicad angle drill. Sawed off the front of the drill base so it more fit the 18V battery base, easy. To right, a 12V Nicad drill I bought new, have not been used much. The batteries are long gone. Again, a Egag battery adapter/ base, some hacking, and now it's Li-Ion

Below, a china no-name air compressor which I bought for SIX BUCKS. I wanted to use it in the basement to blow dust out of equipment, without firing up a compressor. It used a completly oddball and worthless 18-20V Li-Ion so THAT was an easy decision!!
Again, some hacking, and we have a Li-Ion Makita mount. Works GREAT

Showing the start of a Makita 14.4 to Li-Ion 18v adaptation.
Cut out the front area of the battery well, will have two screws from the tool base into the battery holder, an one screw inwards from the rear of the tool and into the new base
