A while back I mentioned in this forum that I have a Simplex Standard (aka "Normal") projector head that I am planning to rebuild. This past weekend I began taking it apart and getting it cleaned up. In general, it looks to be in pretty good shape, although I did find a little bit of rust on some internal parts. This was no big suprise since the projector sat for years in an unoccupied, unheated house, before being stored in a warehouse.

My plans are to disassemble the projector, clean it up, then strip and repaint it prior to reassembling it and replacing needed parts.

I'm starting with a degreaser to get the 70-80 years worth of oil and crud off of and out of the machine. Any suggestions concerning what I should soak slightly rusted metal parts, like gears, in before I put them back?

Clean 'em off with mineral spirits. After they dry then soak overnight in 20 or 30 weight motor oil.

Kerosene also works works wonders for removal of lots of gunky residue, plus it is slightly oily. Also, Ken's idea of light oil soaking seems right on to me.

Kerosene is great!

There have been several posts regarding repainting heads.

Strong is now powdercoating new units, and Mark G. says that he has had great results with this.

After cleaning and stripping, washing with a good clean metal paint prep etchant will stop and kill any corrosion and is excellent for paint prep!

Several people have different types of paint that they prefer. I am partial to Duplicolor High Temp Oil/Grease/Gas resistant engine paints. However, I am currently upset with this product... I must have gotten a can from a defective batch, as there seems to be no hardener in the paint and four weeks later it still has not cured !

Remember to use either Zinc Chromate, Zinc Oxide, or etchant primer on the non ferrous (diecast) parts.

Duplicolor? Cans?

If it doesn't require mixing, baking, or deadly fumes (preferably all three!) do you really want it on your projector?

It has also been said that heating oil will clean parts up quite nicely. Brake cleaner works good too, but will remove certain types of paints and leave your hands dry and irritated. Personally, I use kerosene
