I love a good DIY thing but I have something against crudely made tools for some reason :)
Plus I'd rather pay a few bucks and have one to carry in my tool box that I know wont screw up or break when I need it.

I may take your suggestion temporarily though to finish up these forks.

You can buy this tool from Motobins.com UK
or made it
take a flat chaep fork wrench like 17mm japanese tool kit one
drill 2 holes insert 2 old drill in holes, and weld it flush. 5 mm at the oposite side to take your fork caps

So my question still remains about the master cylinder and I can't assemble it until I find out. Which way does the up that retains the spring against the cylinder go? Is it open end TOWARDS the spring or open end AWAY from the spring?

MC thingy

Without seeing the parts, I have a hard time visualizing the problem. If you could post a pic I could probably tell you right away. One way the spring fits into it and the other way it doesn't, as I recall. I've got some in pieces and if I remember to look I could maybe describe it for you. Lotta ifs...

Here's the MC after I stripped all the masses of rust and corrosion off and repainted with a rattle can.

1. This O ring came in the kit, not sure if it goes here because that doesn't seal anything.
2. The cup (which direction should it go on the cylinder?)
3. WTF is this little washer?
4. Large O ring in the kit. Idk where it goes unless it replaces the one on top of the MC body under the plastic reservoir (that requires some big time stretching.)
5. I already have a washer behind that seal but I have an extra one, does the extra one go somewhere by chance? (I don't think so, I'm not sure where it came from.)

Fuzzy memory:

1) Looks about right. I think I remember stabbing myself with that one, or at least in moving it to its final destination (if that's not it).
2) I am 99% sure the flat side of it faces the spring. That is, it and the rubber deal "mate."
3) I believe that's the one that goes around the allen bolt that holds the resivoir on. From the bottom of the resivoir. (EDIT; you have a slightly different one than mine. On mine, there is a small allen bolt that holds the resivoir on from the inside, next to the big opening. Since yours seems to be a better design, I don't think you have much use for that o-ring.)
4) I think you're on the right path.
5) I think it goes along with the cup (#2) and the rubber deal.

Good photo Blaine!

You've got #5 pointing to the correct spot - between the cup and piston.

#2 - I believe that one sits flat-side to the seal (bowl visible) and the spring seats into it. Isn't the spring smaller diameter on the other end?

I've never removed the actuating arm - what did that involve? It always looked to me that the pivot was peened and not removeable.

Also, in case you don't know (I didn't till recently) you can get brake paint - maybe it's called caliper paint - I'm assuming it's impervious to brake fluid.

Crap! I did know about this and totally forgot. We'll see how well rustoleum holds up before I have to repaint it

Also, the spring is the same size the whole length and does not fit in the cup from what I recall (I'll check when I get home) which is what confused me. If I do it open end away from the spring, it looks like it will cut into the seal there. I should have paid closer attention when pulling it apart. It was the only thing I did not take a picture of when dismantling *sigh
This is why you should take pictures of EVERYTHING as you take it off the bike!

*Edit: The pin holding that arm on is peened on one end and is just a snug fit on the other. I tapped it out pretty easily with a blunt punch and hammer.

Ok, I'll take a look at what I've got in the garage.

I think it cleaned up all right. I basically de-greased the MC then hand sanded the corners and used a dremel for the bulk of the corrosion removal. Taped it off and painted it. The plastic reservoir sat in bleach for a couple days...cleaned it up but not like new, owell.

I took a look at the MC bits and pieces and here's the answer:

That sheet metal cup shaped piece fits with the bowl-side to the rubber.

There's a piece missing from your photo that then fits against the cup. This piece is like a stepped solid steel washer; the center hole fits the end of the piston assembly, and the raised part centers and locates the spring.

I believe caliper paint is only Heat resistant, Not impervious to brake fluid.
