No wonder the motors burn out

The Whirlpool VMW belt drive's use a 1/4hp motor in the smaller (3.4-3.5 cu ft) capacity models and a 1/3hp in the larger (3.6-4.2 cu ft) models.

Mystery Filter and an inconvenient truth about tub size?

Did anyone else notice the SQ "comb lint filter" in the first ad? Who knew! The ad with Mr. Chuck Connors indicates SQ used the same size tub for at least 16 years from the 1960 machine to the new tub in the ad "from the assembly line" on July 14, 1976. By the way nice ads thanks for posting. alr2903

Phil: checked out the Milltronics site-EXCELLENT-My how metalworking machines have changed!!Like the CNC ideas-makes for bettter versatility.And one machine can do more.Milltronic lathes and milling machines go over the edge as to what I was used to here or in that old high school shop.The Milltronic Milling machines cut metal at high speeds usually compared to woodworking tools.They work much like wood shapers and overhead routers.Their lathes speeds allow you to watch a metal turning take shape quickly as on a wood lathe.The VFD drives sure do help here-and the automatic tool changers in these machines-very impressive.
VFD drives are better for reversals of motors over strandard reversal switches-the VFD can control the voltage as well frequency to the motor so reversal isn't going to surge the motor or the powerline feeding it.
For the radial arm saws-since I used to fix power tools-there were three brake methods I could remember-Mostly on DeWalt machines.There was a centrifical mechanical brake-activated by the motor slowing down as you turned it off-activating a brake shoe to slow and stop the motor.Then there is the "plug" brake as in your saw that reversed the rotation of the motor.Last was the DC brake that when you pushed the "Brake" button the machine-a DC pulse was fed into the saw motor-DC voltage fed to an induction motor stops it instantly.
The arbor nuts on these brake machines were a special locking type to prevent the blade from coming off during the brake period.The locking nuts must be used on these machines-DeWalts.The blade guard should keep the blade from flying out of the machine-but scary nonetheless.
