Topic: 67 hood spring finish

[gimpystoy]

67 Metuchen, May build.
Hood springs bare?

[CharlesTurner]

Hinge and spring would be phosphate & oil.

Thank You

The spring would be darker as it was made from heat treated steel.

Not certain that the beginning finish and look had allot of impact on the final, after plating, look and tone. If so its been my experience that it is/was not noticeable. When plating them today care must be taken with heating them for plating since you can effect the structure of the metal if you use too much heat or cool it too quickly

Just my experiences

Well add this - heating any iron or steel item between 180 F and 212 F for phosphating is not going to affect the temper. I've found the typical temperature in my tank is around 190 F to 200 F. That goes for the maximum ten minutes of plating. I let the item cool a few seconds from the hot tank to being is dipped in rinse water, so the temperature has probably dropped to 100-120 F, just about where it can be touched (don't, there's acid on the item).
However, zinc plating temperature get up to 380-390 F (maybe higher) in the process and that does have an adverse effect on the temper of steel. This is from conversations with my plater. There is an additional step to reduce the effects of embrittlement where the item is baked. I assume that cad plated items are similar. I've had a few washers crack (they may have been stressed in use), and an occasional screw heat twist off (too much torque?) that I had zinc plated. It's not an absolute.

Just passing on concerns and comments from those that do this for a living. Metallurgy is not my area of study

+1 the identical process renders a darker spring than hinge every time. Perhaps with the time and heat cycles it dulls down to look closer to the hinge in tone. They all look different than new with time regardless as witnessed on survivor cars.

Metallurgy is not my area of study either, but back when I worked for a living, I evaluated subcontractors as part of my responsibilities, platers included. There were many facets to this function, but in the case of platers, the plating process was critical, and somewhat interesting. You pick up little bits of info that get called on later in life. I consider my current plater a friend, he is car friendly, owns a 1967 and a 2006 Mustang, and answers my plating questions willingly (I do bribe him with a bottle of wine occasionally). Just passing on "the process".

Wow: I'm always getting an education on here. It's wonderful!

I refinished my hood hinges/springs a few weeks ago and have provided a few pics.  I used magnesium phosphate to parkerize the parts.  I'm pretty happy with the finish but due to the size of the parts and the pot I was using, they were finished in two different batches.  I think the color is slightly different...in the right light.  However, once on the car, I don't think it will be noticeable.  The first photo is the set-up picture after the hinges and springs were blasted and cleaned.  The second picture is the completed parts with a darker, more uniform parkerized finish.

I got so good news and some bad news  . The good news is the hinges and spring plating look good. The bad news is the hinges are replacement style . 67 style is different. That style hinge wasn't used until later 68 Mustang production. Typically seen on 69/70.I'll let others post pictures of 67 earlier 68 hinges to show difference. I hope they are going on a later 68 and not a 67 like the heading of this thread indicates.

We'll Bob, that' not bad news....that's terrible news!  Until, 5 mins ago, they were supposed to go back on the (Dec 67 built) 1968 Mustang.  They came off the vehicle I've owned for over 10 years, they always say you never know what you'll find on a preowned vehicle.  I knew the driver side fender had been replaced in the 70’s with a ford replacement part, presumable it was hit at one time.  But now, it appears the hinges were likely replaced during this same incident.

It looks like I have a set of (replacement) hinges for sale and I'm in the market for an earlier set.  I guess I'll get to further develop/ improve my parkerizing skills.  Thanks for your "observations" Bob....I think

I'll check and if I have a early set on the shelf.

That is indeed horrible news, Lee!
Putting all the time and effort in restoring it, and then finding out there not the real deal...
Always want to learn more, so... how do you see/know that the hinges are aftermarket or real?
