Hardinge Lathe 204 frame Motor

Looking to replace the 204 frame motor I watched my favorite teach on the subject

and that pointed me to the plate on the motor I have

Reading deeper into this, this is an OLD style of motor frame. 204 Stopped being used in 1953… Of course, mine is a discontinued motor frame…

Looking more at this I see the 203 and the 204 frames are similar it’s the screw mounting width that is different. I think an adapter plate could work. The only dimension that matter is D and U. U is 3/4″ so the center of the motor must be 5″ from the bottom of the plate. Obviously P must be smaller or equal. Watch out for the boxes that stick off the side for the wiring to enter.

LOOKING AT A MODERN NEMA CHART:

A D of 5″ is no longer a standard. The closest D is 4.5″ that leaves 1/2′ for an adapter plate.

All the newer motors have 7/8 shaft meaning the pully will also need to be changed. The 145T looks interesting… Some shopping:

There is hope.

There are also sexy stainless steel motors….

there are charts for the motor mount brackets:

JL Sub-Woofer

Took a look inside a JL subwoofer… quite the coil and suspension system.  http://www.jlaudio.ca/home-audio-powered-subwoofers-fathom

JL audio dominates the Car stereo market in terms of driver quality.  The salesman said the best line “We learned a lot from our 12 Volt line of products in designing this home theatre sub”  so from now on, Car audio will be forever “the 12 volt industry”

Moving stuff across the country

I most certainly had a busy “reading week”.  It started with finishing up a job My brother Mike started.  Moving 7 pallets of equipment from my moms garage in Saskatoon.    Followed by great visits with Family and friends.  I’m sorry I did not get the chance to meet with everyone I had planned to visit with.  Things got a little busy in the IT support world and there was so much family to visit!

Custom made dollies were built for the two large sections of console frames.

Modules were packed, boxed and palleted.  A small fortune in bubble wrap and pallet wrap were employed.

I’m excited to work on these projects again in my “Spare time”

Stay tuned for updates of what’s happening with this lot.  We’re very excited for what’s planned :-)
