I bought the router speed control from

$24 including shipping. In a previous thread, someone said this
device worked better than the one from HF.

this sounds like a good match for the dc treadmill motors many have
bot for their home shops. it says up to 3.5hp.

I tried it on a Singer 401 sewing machine. Huge improvement over
rheostat control! No "hand starting" even at very low speed.
Making a footpedal control for it is now on my project list.

yes, sewing machines have used solid state speed control for many
years. what is _not_ commonly known, is that the foot control is
simply an air chamber. the actual circuit resides in the head and
is pneumatically controlled. --Loren
