Colil bracket recondition question-Gerry?

[Charles P.]

What would be the correct way to restore this bracket. I believe it had a bright zinc finish almost like a galvanized finish. As you can see it has oxidized to a matte gray. This is off a 73--low miles but things still oxidize!

Re: Colil bracket recondition question-Gerry?

Charles, You are right about the finish being like a galvanized bucket. Some of the NOS FI coil brackets I have are cadmium and some are like the galvanized one you have. I just have them all cadmiunm plated and no one complains. John

Re: Coil bracket recondition question-Gerry?

This is a commonly reproduced part and cheap too but I have noticed differences in the remakes therefore I want to rehab this one. Any recommendations on Cadmium platers? Thanks

Coil bracket recondition question

Charles,

I'll bet if you dip that part in Jasco Metal Etch(2 to 1 cut) for a half hour, then dry it off, and use a fine wire wheel on it, it will probably look like brand new. Then protect it with a coat of WD40 or TriFlo.

The part does not look like there is any rust coming through. You'd be surprised how some of these old parts just clean up. Take a look at these 67 hood latches:


No replating at all, just a cleanup and brushing (maybe a little paint on the spring).

I have found if you have a bead blast cabinet you can turn the presure down to 35# and use fine glass beads you can clean off just the oxidation. Have the glass clean so you can tell what is happening to the part. Aim the gun at the part and use short blasts on the foot pedal. The secret is use only the least pressure you can and short blasts. Try it on a part for a test till you get the feel of how to do it.

Re: Coil bracket recondition question

wow! those look like NOS. good job.

Re: Colil bracket recondition question-Gerry?

I had thought about that but I don't know of anyone who has a cabinet close to me. I may attempt the metal etch is that 2 parts of Jasco to 1 part water or vice versa? Also I have an accelerator bracket that was gray phosphate that I want to recondition. What is the best way to prep it prior to cooking it in the grey phosphate crock. If the best way to prep is to glass bead blast it then I will have to see if I can borrow someones cabinet for both brackets. What is the cheapest setup to get for prepping small items like this? See part below--just a bit of surface rust and paint.

Re: Colil bracket recondition question-Gerry?

Charles,

It would be 2 water to 1 metal etch, all you want to do is soften up the corrosion and let the fine wire wheel do the rest. Then you can follow it up with a medium/fine Nyaloc (nylon) wheel for the polish. You could also try skipping the metal etch step and go straight to the wire wheel.

For the gray phosphate part, you need to get it down to bare metal. A solution of 2 water to 1 muriatic, will take the old phosphate off in short order, it will even take zinc plating off. You will see it bubbling. Then neutralize it and use the wire wheel for the final touch. You could also beadblast it.

Re: Colil bracket recondition question-Gerry?

The gray phosphate bracket looks good enough to just oil with WD-40 and that rust may go away if you wipe on it some.

Cheapest setup for preping small parts

Charles,

That's a nylon abasive wheel, but you can also get a fine ss wire wheel for corrosion removal and polishing. See the Weiler rack at your hardware store. They make both.

I use a 3" and 4" wheel to get into the crevices of parts.

Re: Cheapest setup for preping small parts

Gerry/Lyle--Thanks for all the advice as usual. I believe a trip to the hardware store is in order for, at the least, some metal etch and polishing wheels. Give me a bit and I'll post pics of the final product.

you hold the trigger down with one hand and the part in the other?
