REVISITING 50/60 HZ

1402:

Re-configure the primary power for 220v Delta.

Swap the Ferro ( which is already in question ) with the tour 1402 Ferro.

Swap the read and punch motors with the tour 1402.

Lab 1402 is now a 60Hz machine.

1401:

Swap the Ferro with the tour 1401 Ferro. The fans don't care.

The power supplies are adjustable,and were tested with 60Hz.

Lab 1401 is now a 60Hz machine.

1403:

Swap Carriage motor ( 1/3 Hp ) and Chain motor (very speed sensitive) .

If there are problems, swap T-Casting or entire 1403.

Lab 1403 is now a 60Hz machine.

729:

Sharper minds would have to help me here;

but an E-Mail from Kantmann to Garner (6-16-04)

suggests that converting to 60Hz Is not prohibitive. Someone must have investigated.

Allen would stop beating us up about questionable power.

1406:

The 1406, at this point,is electrically transparent to the system.

Being able to use the 1406 is a long way off. Worry about it later.

PROS:

* Virtually no cost or waiting time.	* No converter/generator to fail.
* Single power source.	* Less lab space. *Less operator training.
* Less power (way less)	* No noise * No heat.
* Reduce the number of C8s from 6 to 1.	* Less work for an electrician.

Contrary to perception,we're more efficient now than we were 4 months ago.
We know the primary power system pretty well now.
I think a few full work days, with good participation, could get It done.
