'66 jack restoration; some follow-up questions

[Gary B.]

I read with interest the thread from a few days ago on restoring a mid-year jack, since this is currently on my to-do list. I have a couple of follow-up questions. As Jerry Fucciloo noted, I realize that in order to get paint coverage on all the parts that should be painted, one has to raise or lower the jack in between coats of paint. My first question has to do with what happens to the jack during judging? Does it get raised up and down, say during a PV? I worry that raising it up and down will scratch the paint where arms slide and rotate past one another, so I'd like to do my last coat of paint with the jack in the most common, judged position, which I assume is fully down. Is this correct? But in a PV am I going to have to show that the jack operates smoothly? If so, how much does one need to raise it?

Second, on my original '66 jack the two cad/zinc washers with the plastic washer in between are not at all pristine and I'm wondering if anyone has any suggestions for how to spiff them up without dismantling the jack. Or do I just have to live with them in the present condition? If the rest of the jack looks pristine after painting, would one lose more than 1 point for those three washers showing their age?

Finally, does anyone have any suggestions for what kind of gloss paint to use that comes in a rattle can? I've had very poor results with Rustoleum gloss black in the past because there is so much non-pigment in what comes out of the can. Are there any other rattle can gloss black paints that work better than Rustoleum?

Thanks,

Gary

Gary, I have had very good results with SEMS spray paints. Good coverage and you get your money's worth out of the can

Dick: What retailers sell SEMS brand of paints? *NM*

Gary,

During Flight Judging the jack is normally not exercised, but during PV you have to demonstrate that the jack goes up and down using the jack handle.

Re: Dick: What retailers sell SEMS brand of paints

Gary, my local Carquest and NAPA both stock it. If you will do a google search there are several retailers that sell the paint online

PS. Is the large nut painted? Or naturaL?

The photo in Jerry's post from a few days ago appears to have an unpainted nut. Is that correct?

Gary, its very easy to dismantle the jack. Use a small punch to remove the roll pin (located on the screw shaft and protruding) that keeps the lead screw captive and then unscrew the lead screw. Now you have the washers and nylon bushing separated. Clean them up and you are good to go. It is my understanding that the nylon bushing is natural and the washers and screw nut are black as well as some paint on the screw on the "bolt end". Mine was judged that way more than once with no deductions.

Re: PS. Is the large nut painted? Or naturaL?

The nut is welded into the u shaped bracket and was painted black.

Re: '66 jack restoration; logical assy

I know the judging manual says the nylon bushing is natural.....
However if the jack were assembled logically following the paint scheme then I would believe the jack was completely assembled with the screw in place and roll pin inserted; then painted. This would explain the paint at either end of the screw for a few inches but then the nylon piece would be black. Now if there were a "release agent" left on the nylon from the molding process the paint might not adhere and it could be natural looking.
Comments????

Gary,

Both nuts on my 67 jack were painted. The business end nut in previous picture just looks unpainted from the reflection, but it is painted. Here's how the jack looked before I refinished it:

One can see that part of the screw and shaft were also originally painted.

However, the washers on both sides of the nylon spacer are zinc plated and not plated. To clean the washers up, I just used a little steel wool and a nylon wheel on them, and then carefully masked the washers with the nylon spacer for painting. I didn't dissassemble. I used a gloss black lacquer, not enamel (I forget which brand).

As you note in the picture below, the rivet in the jack handle was long gone and replaced with a carriage bolt. But I found a junk yard Japanese jack, with
a similar rivet and replaced the carriage bolt with a makeshift rivet.

Here's the after again:


Having fun,

Gary,
Someone may have already hinted at your question regarding PV judging. If the jack operates as it was designed to, you'll get full credit during PV regardless of its condition.

Re: '66 jack restoration; some follow-up questions

A few comments on the jack. When I took mine apart (lead screw) the "roll pin" was not the standard roll pin it was however a solid pin which projected out of each side (about 1/16"). The two washers did not appear to be painted, nor was the nylon bushing, nor the solid pin.

I have owned this jack since early 70's and do not recall playing with it until this year. It was out of car in mid 70's and never returned until this year.

The Type 1 jacks have the bearing instead of the 2 washers & nylon. The bearing is natural while rest of jack is painted. Sooo one could say that the bearing was added to jack after paint operation - that's why its natural. If such an assembly was started for the Type 1 jack it may have been continued for the Type 2&3 jacks.
It's not logical (not everything is) that the jack would be painted with 2 steel washers on, then taken apart - the nylon inserted - then put back together again. And since I found the solid pin unpainted that again points to an assembly step for the 2 washers and nylon and solid pin.

If nobody is going to hit you at PV or Flight for natural washers I would leave them natural. NOTE; not an expert on jacks.

Consider this scenario

Alan,

The jack parts were painted or dipped in paint separately before assembly. The threaded screw had one end dipped in paint. Then the jack was assembled with the zinc plated and nylon washers.

Sounds logical to me.
