| An unassuming gray box holds the key to worry free motor tool excellence. |
This has to be one of the best investments I've made in my hobby tool set. The Dremel Solid State Motor Speed Control lets me dial the motor tool speed down to a near crawl. I've shattered countless cutoff discs and melted too much plastic with the high rpm built-in speed control Dremel tools. This vintage beauty combined with an old Weller motor tool lets me use a spinning grinding and cutting tool the way I always imagined - with careful precision - to do fine work.
Note: this variable speed control was made for single-speed, on/off motor tools only. Fortunately they, like the speed control, can be found readily online. Not sure where I picked up this Weller but I'm glad it survived the latest round of tool purging. I found the speed control box on eBay in its original packaging, with spare fuses, for under $30. Of course the low speed operation doesn't have much torque, but for grinding and shaping soft material this is definitely the way to go.
