Building my control pannel, have some questions on transformers.....

[lionelsoni]

The body of the Z is 7 3/8 inches from front to back and 7 5/8 inches from side to side. There is a shallow decorative molding on the surface that may add about 1/8 inch to these measurements.

The baseplate is 8 inches from front to back and 8 11/16 from side to side. There is a mounting hole on each side 7 7/8 inches on centers to clear a #6 screw.

You could remove the baseplate to mount the body directly on a non-flammable surface. The holes are 6 3/8 inches on centers front to back and 6 11/16 inches side to side. The holes are tapped for a short 10-24 screw into bakelite and are fragile. I would add shim washers to reproduce the 1/4-inch or so spacing to the original baseplate.

I'm pretty sure the Z is the same size as the prewar V transformer. 8 1/2" wide by 8" deep.

Sorry Chris I misread your question as referring to a ZW. I do not know the physical dimensiions of the "Z". All I recall about the Z is that it is a "higher voltage" transformer rated at 6-24 volts variable output on the A,B,C & D binding posts.
Hopefully someone who is familar with the Z will respond.

Dose the Z use the same base size as the ZW?

The postwar ZW's base is 6-1/8" x 7-5//8" [overall transformer body occupies a space of about 7-3/8" x 12"].
Two Diodes replace the two old copper disc rectifiers[washer-like discs]. A 40 amp Anode-to-Case(+)Stud mount Rectifier Diode will do the job. The threaded stud goes in the mounting bracket hole from which the disc is removed and is retained by a 7/16" nut. The body of the diode is 11/16". You will remove[desolder] one wire from the old rectifier and resolder it to the new diode's terminal.

You can buy the 40 amp Diodes, catalog#1N1190AR $3.50 each, from ALL ELECTRONICS Corp at 1-800-826-5432 or fax [phone].

(The 40 amp size sounds like overkill but you want your diodes to be larger than the transformer's circuit breaker so a surge or short will trip the breaker instead of blowing the rectifier diode).

working on a layout for my control pannel, i'm planning on using a postwar Lionel Z transformer to control some of my accessories.
Dose anyone have the dimensions of the base?

I also read somewhere about replacing a whistle rectifier disk with diodes, what size diodes do I need, any where can I find a schematic on how they are
wired up?

Thanks for your help
