I took a few photo's not sure if these are ok but let me know. They're of a Parkinson No6.
Hey Vono,Carsten, here's some more
I was talking about gold leaf, and my Wife said she had some metallic pens.
Hello Carsten, no problem you're welcome.Hey Vono,
you've done a hell of a job!
I thank you very much for your effort.
By comparing and relating, I should be able to recreate the dimensions of the missing parts, along with measurements on my vice.
One more thing: I only have the spring from my Woden 190/7A as a comparison so far, they are 21 coils, a coiled part of 72mm length, the outer diameter is 20mm, the wire thickness 2.4mm, so the inner diameter should be about 15.2mm and thus the spring should lie quite loosely on the 1/2" round material.
Are these roughly standard dimensions for Parkinson's as well? I counted 20 coils in your picture, right?!?
Thanks again.
That does look very good Mike, congratulations.
You should ask your wife more often anyway - says my wife ...
Have a nice evening all

Thanks. The metallic pen has a very hard porous tip, so it was easy to follow the top of the raised lettering without going over. Also, the gold seems to have a fine satin look, which blends in well with the age of the patina on the vice's. It doesn't look new, but looks like its always been there.That does look very good Mike, congratulations.

She is brilliant. I wouldn't have returned half way across the world to marry just anyone................. You have clearly found the better method! Sorry, your wife has.

However, it is rusted solid. Nothing moves. Handle doesn't even move in the spindle nose.
Welcome Greame,
I can only warmly recommend it here, I have recently been very kindly welcomed myself!
First you should say what type of vice it is (front or rear opening), prism tracks, should the nut turn or the spindle, spindle protected or unprotected, how big is the part (will it fit in an ultrasonic bath)????
Pictures usually help too.
I would do it like this:
- Hot soak and wash with household grease solvents so as not to mess up later agents with dirt;
- Rinse with water, pressure washer;
- Soak in hot citric acid solution, several times if necessary, the surfaces should have changed their appearance;
- Rinse with water;
- Blow dry with compressed air and continue drying with a hair dryer or similar;
- Soak in a penetrating oil of your choice;
- Try to move the controls again and again over a period of days in the penetrating oil;
- Resilience is more important than strength;
- Change position, let the oil run in and out of cavities;
- Replace penetrating oil that is saturated with dirt;
- If nothing moves after a week, ask again with further information.
I never had to go further. Someone else must help from there
Good success!

Hi Vono,Hello Carsten
As promised some QR spring pics
Hope they help
A nice Fortis you have there, I wouldn't worry about embrittlement, I've used electrolysis on a number of vices now without issue.That's pretty much what I had planned, just wasn't sure if to use the citric, or replace that step with electrolysis.
I have done a fair bit of citric de rusting recently (every steel part of a 1950s motorcycle). But since then I've also been electroplating stuff (every nut bolt washer and chrome part of a 1950s notorcycle).
That's why I wondered about trying to remove rust that way. Maybe I'll try citric first as it's not line of sight.
The vice in question...

A rare one, but apart from the missing jaw, and not one single part still moving, it seems ok. Doesn't seem to have had much abuse.
I just don't want to weaken it. It won't get abused, I use my record 112 for abusive jobs, but it's going to be a reasonable amount of work to sort out so I don't want the dynamic jaw to fall off first time I clamp anything down in it!

I'd go with electrolysis first if it was mine.

Ok, maybe I'll give electrolysis a go. I have everything to do it.A nice Fortis you have there, I wouldn't worry about embrittlement, I've used electrolysis on a number of vices now without issue.
I'd go with electrolysis first if it was mine.
For me, electrolytic rust removal would come after all the other measures.
If it is stuck solid I'd chuck it in whole and run it for a while, take it out and pressure wash it (as I can be a bit lazy), then try taking it apart. If it won't come apart still try another go in the electrolysis tank and repeat. You have nothing to lose but time and it may stop you damaging/breaking bits.Ok, maybe I'll give electrolysis a go. I have everything to do it.
As it's line of sight, I guess it would be best to try and get it apart first, then do the pieces individually?
My be a citric soak first will loosen it all up. Might try and get the quick release mech out first though so as not to risk damaging the spring.

Same here.
