The dash light was missing the cap or cover. The new ones being sold are about 35 bucks. Mine is mounted in a hole in the dash the ones being sold are surface mounted so I figured I could make my own. I used copper pipe and made a brass end cap.
It’s one of the benefits in having a lathe.
It was not just the money but the satisfaction of making it yourself.
I was going to paint it black or leave it as is.

Does anybody know how to give copper and brass the aged look?

You should be able to upload more than two pictures. Pretty sure I've done as many as six or seven occasionally.

More than two or three may not show up in the preview. Just hit the button again and a different two or three will show. All if them will be in the final post.

Aging copper & brass: Don't polish. Just wait.

To age it just handle it with your bare hands. Mine only takes a few days after someone touches it.

Nice work Peter. I like seeing fun stuff like that. Troy has a good suggestion. If it was mine I would try to match the black on the base. On these wheels I put gloss black on and then daubed flat black over it. After it dried I scuffed it with a scotch-brite pad. I also like to let a little muddy water dry on it and let it wear off from use. The main thing with patina is it is not consistent all over. Some random nicks would help.
The nice thing is you can try several things to get it like you want.

Thanks for sharing the project.
Rich

A solution of vinegar and salt will rapidly patinate brass and copper.

Thanks Rich,

I'm soaking a test piece with a concoction I found on the internet vinegar, salt and ammonia.

I also thought of burying it in dirt for a week or so.

Chrome shops can simulate an aged copper finish they call florentine copper.

I usually pour some loose black powder on it and light it, of course building and working with flintlocks I have black powder handy.

Liver of sulphur will turn copper near black, but does not tarnish brass. Sulphur in the gunpowder will likely put a patina on copper. Brass will acquire a patina when exposed to the fumes of ammonia, or similar solutions . . . like urine. Fuming gets more result than applying the liquid.

I'm really curious about the vinegar/salt solution, as that mix will remove all tarnish from copper when applied hot. ?? Maybe it makes for a patina when cold ? Chemistry was never my long suit . . .

It appears your dash light was painted black. That should solve the problem.

Rich's post reminded me of the story that Rodin used to instruct his children to urinate on his newly cast bronze sculptures to give them the patina he wanted.

Just about any mix of green antifreeze and water will tarnish brass like crazy—which is something I've learned because the riveted-on neck of my radiator leaks and after each ride, I must wipe up a few little neon-green pearls to avoid the overnight tarnish they would otherwise bring.

Just remember nitrogen (what's in pee) also found in mirical grow will turn the parts green. For a proper patina the parts need to be browned and then if you like somewhere where they may frequent salt air.

If it were mine I'd just paint it satin black (to match the rest) and call it a day. If you really badly wanted to accelerate the wear on it to catch up with the rest of the car I suppose you could take the cap off, drop it, then reinstall it every couple of days for a few months to simulate ninety years of bulb replacement, but I would just let it age naturally.

Looks good Peter. I have the opposite problem - I'd like to have a nice bright, shiny brass one to match my brass speedster. Would you be interested in making another one out of brass?


Top of pagePrevious messageNext messageBottom of page Link to this message  By Rich Bingham on Saturday, October 22, 2016 - 12:00 pm:

That looks great. I realize in the fever of getting it tarnished I forgot to sat what a fine job you did of making it !!

Thanks Rich.

Seth,
I would have no problem making it but the material would be a problem.

I made mine with a piece of copper pipe and a scrap piece of brass. The brass was used as an end cap soldered to the end after it was machined to fit.
You want a solid brass cap so I would have to have a piece of brass rod. I did a quick search of Granger's, they have 1 1/4 dia. x 1 ft. brass for 83 bucks McMaster-Carr only have 1" dia. Stock, the cap OD is 1 1/8 and the ID is 1" and its 1 ¼” long. The length and size of the hole for the bulb hole were a guess on my part using a photo. I would need a piece of stock at least 2” long.

Seth - most if not all dash lamp covers/hoods were brass - find one that fits & polish it.

Steve that sounds like a good plan if I can put my hands on an original one. I don't have a dash light at all, so the only ones I've seen are the reproduction units the vendors sell.

I have used this shop class method a few times. Just dip the part in motor oil and burn it off with a propane torch. May have to repeat several times to get look you want.
