I am currently restoring/preserving two vertical shaft E-7's.

I am cleaning all the muck off the die-cast parts (black wrinkle finish) by soaking in warm soapy water and carefully scrubbing with a sponge and shop towel. Problem is that when the parts dry, the finish turns brownish. Anyone know what in the paint is causing this?? Remember that these are zinc/pot-metal die-cast parts that do not rust.

The machines will occasionally be run...so I wanted an opinion regarding appropriate preservation grease/oil.

Mark Gulbrandsen: I e-mailed you regarding some intermittent and spare parts help. You never responded .

Cheers

Will,

What you are seeing is actually the dirt. You've pulled the oil away and are seeing what is left.

Now...try with a cleaner like Simple Green or Zep Spree with a tooth brush and water...you have to brush pretty good but when you are done...you should see the original finish.

Thats because I've been on the road. I'm actually in Louisana right now enjoying some great Cajun cook'n!!! I'll will call you when I get bck to SLC.... probably over the next weekend.

I suspect that something in the detergent you're using is reacting with something in the paint. Remember there IS lead in the paint from that era. I use Dawn Detergent, seems to be pretty neutral in and of itself and it's great at cutting grease. I reccomend that you use Dow Oven Cleaner or some other type of oven cleaner who's fumes won't knock you on your ass. I've used oven cleaner for many years on most projectors to remove the grimy dort and dried up oil that accumulates. BUT! If you're not careful it will remove the paint. Don't make the water too hot, that increases the likelyhood of stripping the paint off or bublin it up. Spyar it on and swish it around with a fairly still brish to loosen the crud up. Then rinse in cool water and make sure you get all the cleaner off. I reccomend that you experiment a bit before doing critical pieces or you might be re-painting some of them... The gray wrinkle paint used on Centurys is durable and particularly good to clean this way.

If you have access; ultrasonic unit with water soluable cleaning solution. The unit we have is just like the jewelry shop except about 200 times more powerful. Louis

Try "scrubbing bubbles"...seriously, this stuff really gets off some nasty stains and crud.

Will,

I have a vertical shaft E-7 that has a stripped shutter shaft. Let me know if you need any parts. I'll send them to you free if you pay for shipping. Don't really want to deal with parts that are hard to remove though as I don't really have a ton of spare time, but any easy to remove parts let me know. It is in very good physical condition.

Hi All!

Thanks for your help. Soaking and scrubbing in mild dishwashing detergant and warm water was not quite effective enough. I had some Clorox Bathroom Cleaner in the spray bottle on hand and decided to give it a try. A couple of sprays immediately lifted the dirt without attacking the wrinkle finish. The result: WOW!

Mark: I look forward to your call.

Adam: Please hold your thought on your E-7. I have a couple of parts machines and maybe we can restore yours, too?

Also, the Mercury switch lead in the spot sight box: does it attach to upper pin P-643-D or lower pin P-644-D. The E-7 book is unclear.

Cheers

Kutler
