Thoughts on this? Copper scrubbers + tranny fluid = low dollar filter media?

I like it. I need some for one I'm working on now. Why tranny fluid though?

Jdpan!

I believe there is a lacquer-like preservative on them that must be removed first.

Cotten, 10 cents?, that one has been around for a while!

but you're right about the coating, an over-night soak in a coffee can with lacquer thinner takes care of that.

The oil helps to grab some of the micro dust particals that might sneak through.

And you can tell by the color (ATF, or even MMO) that it isn't a motor leak when it drools all over the tappet blocks.

Instead of plastic wire ties, I use the big copper-colored staples that cardboard boxes are often sealed with.

I just used what I had on hand... Whats the advantage of the staples? Theres three of the scrubbers on there and the wire ties seem to hold them all together pretty well.. I might have some of those staples around the shop, maybe Ill give em a try.

My first fear would be that the plastic would eventually become brittle.
The large staples, penetrating the mesh from the outside of the support screen, and then bent upon their ends to lightly grab through the support screen's holes, would have a very difficult time to get inside. (photos pending...)

Another concern, particularly for J-slot covers, would be that you have the ties where the cover and backing plate would pinch them against the edge of the support screen, allowing vibration to eventually cut them.

Staples are not my idea. That's just what I always found, although usually smaller, and not as aesthetic as copper-plated box staples.

I see what you're saying, on the other hand, if by chance the a staple came loose and got swallowed, I'd much rather have the motor chew up plastic rather than metal. Maybe there an in between somewhere?

I use ordinary safety wire. Not the thin stuff, and not the thick bailing wire either. Medium gage. Don't go around the outside. Stick it down "through" the mesh, like Cotten mentioned, around the support screen and back out. Don't twist the 2 wire ends too tight. Keep the mesh "fluffy". Just my 2 cents.

Just for clarity:

Note how the staple is outside of the support screen.
(Modern element support shown on right for better visibility.)

Even when loosely crimped to keep the mesh "fluffy", it is securely trapped.
