Topic: 64 1/2 June Fuel Filler Neck and Hose Clamp Finish

[FXguy]

I have a plater that can do the filler and straps in either a bright or a matte tin finish.  Based upon both the original appearance of the straps and a comment in Jeff's pdf article where he states that the reason for using lead/tin on the filler tube might be that it is non-conductive, unlike zinc.  One would assume you wanted the same thing on the clamps.  So I am wondering two things:

1. Is the filler better finished bright or matte (see example pictures).  It would seem that when new it would have the bright look but as the finish oxidized it would look more like the matte.

2. Would the the straps be the same finish (Note that he tightening screws look to be clear zinc, so those are being plated separate from the straps).

Thanks,

I have had numerous 'correct style" gas filler necks over the years and they would more closely match the sample marked bright. FYI there a assemblyline style with the "crook "in the bend NOS filler neck on ebay right now..

I've restored a couple dozen filler necks.  I send them out for hot tin dip and then have a combination of blasting/tumbling that results in a nice original looking appearance.

Thank you Bob and Charles for the input on the filler neck.  Any thoughts on the clamps?

Best I can tell on the clamps is cadmium plating on the bands and zinc set square nut and screw.

Your 64.5 may have had crimp clamps on the filler neck.  Although I haven't ever determined a switch over date to the common style.

Please share the process you are using.  I got my tin plated original back and am ready to start on it.  I also read Jeff's library which I'm thinking of trying. 

I attached a pic and would like feedback on the roughness of the tin plate, prior to doing any of the techniques.  Thinking of sending this back for a smoother plate.

TIA

Guess you didn't check the article in the Library of how you can achieve this at home. But will admit its much easier to send it out if your only doing one or two. Though it was fun, felt good to be able to figure out how to do it and end up happy with the results.

Actually, I did read the library article which was informative, but had to make some choices on which stuff I do myself and which to farm out and this one got farmed out.  I'm thinking of using the mag wheel cleaner you suggest, but first I'm wondering if the roughness of the untreated tin plate in some places should be corrected first, or if this imperfection in the plate is more indicative of what we'd see from the factory.

Because of the thickness in parts of the finish, pooling, flowing and such I would not expect to have a perfectly consent finish across all of the surfaces but the underlying metal would have not been textured. If I have roughness I use light sand paper before I add the plating to the item.  Flattening of the finish from the shinny step tends to make the differences in the finish (often go back and reheat the area) less noticeable

Sorry I missed the mention of reading the article you posted above. Catching up after being gone for a few days

The part was very smooth and clean before going to the plater, so the variation is purely a result of variations in the plating itself.   The plater said that they'd take it back and redo it.  I'm thinking that I'll go ahead and send it back for now.

Thanks Jeff.

No worries.  You replied while I was still editing the post and adding pictures

My finishing method requires a vibratory tumbler.

I saw that was one of the things you mentioned along with the light bead blast.  I have a tumbler and thought about putting this in there to smooth it out.  Have ceramic in there right now but I'm a little concerned that it will take too much material off the edges of the flange.  I'll revisit all of this after I get the part replated.

Thanks Charles.
