Electrolysis, and cast iron.

[brino]

.....found one more online reference....

This site:
http://www.oldengine.org/members/diesel/WipacMagneto/wico11.htm
seems to list a BESA letter code to various magneto shafts

This page:
http://www.oldengine.org/members/diesel/WipacMagneto/MagTaper1.htm
gives dimensions for the three letter codes.

Cast iron is probably the best material for using electrolysis.

Thanks for that information peeps
Cheers

RE: BESA tapers
I still have some searches going on my collected reference material, but so far no luck......

says:

Every mag I have handled with a taper spindle, has a BESA taper...even the French used this standard. Never stated in degrees, the slope of the taper is 1 in 10, regardless of taper size..​

I'll keep looking.

Here's the direct link to the American Machinist article from July 27, 1922 that Dave H. (@British Steel) mentions above.......

All thanks to Dave H. for the interesting article!
It has some great history like:

EDIT: By the way, I am sorry if this is tending down the path of a discussion of tapers rather than electrolysis of cast iron, but from the feedback the originator is on board with it!

I can't find much information about the Pallas mill, apart from on www.lathes
It's about 4'6" high, and the table is 30" long.
My mill has a single phase 3HP motor, not 1 HP motor as they show on www.lathes, I'll probably fit a 3 phase motor, and run it from the VFD inverter that I use for my Colchester lathe, so speed control/FED&REV will be a doddle.

Try this link: http://www.lathes.co.uk/pallas/ or maybe that's the same one.

Yes, that's the same one, but Thanks

Hi. I'm back again, been busy removing paint with caustic soda and wallpaper paste, and rust from the mill using electrolysis, how should l clean the rust from the feed screws, phosphoric acid, or electrolysis?
I'm also building a tank from old doors lined with plastic sheet, so l can put the main body of the mill in, and use electrolysis to pull rust from the knee dovetail on the front of the mill
Thanks

Electrolysis works fine for feed/lead screws.

Great. thanks
