Q. My initials are PAW And I am trying to restore an NCR 324 candy shop automobile. The paperwork on the bottom says it went to Chicago Illinois and bought by Mr. Knox of the Woolworth family. I have been cleaning information technology with Brasso and much elbow grease with tiny tooth brushes dipped in warm h2o and then rinsed with a soft cloth.
I need to know if there is a booklet bachelor that will tell me how to take all of it autonomously every bit I take the sides and back off merely I need to get into where the keys are because there is much gunk on them. I have Dummy keys which I accept bought and would also know if they can be made into real keys instead of just the dummy key. Whatsoever help that I can receive will be virtually valuable and I would capeesh any aid.
I am non able to exercise any type of sand blasting or anything like that but I want to restore it to its rose bronze originality. Thank you for whatever assistance that you can give.

A. I am in the same boat. I bought a cheap sand blaster and used crushed walnut shells from Harbor Freight. That worked cracking on the brass. After that I used a wire brush bike on an electric polisher and then cloth pads on the same polisher with jeweler's smooth (green stick) on them. That shined it up great.
As far as taking the affair apart and trying to fix it, you can offset with a repair transmission that you can observe on ebay. Just search for it. Only, unless you are super handy, yous won't be able to do it. I had to finally pack it all upwardly and haul it to a place in Houston that does them. Its going to exist expensive, but it's for my father-in-law and he's most 90 years old. He bought it 20 years ago and had planned to restore it but he wouldn't spend the money. Well, he's going to come across it washed.
Good luck to you.

Q. I am restoring a National model 313 cash register. I need to find a booklet with pictures and instructions to help me reassemble the parts that were cleaned. The core of the machine is still intact, had sense enough not to disassemble it, but I have not had any luck getting it to work again.

Q. I'm restoring a National Greenbacks Register with a case made of very ornate red brass. Being virtually one hundred years old, the case is tarnished to the indicate where it is virtually black. Many polishes will remove the tarnish on the flat surfaces, however in the deep crevices the tarnish just tin't be reached with polish. Is there some type of chemical solution in which I tin dip the parts in club to remove the tarnish.
Thanks for your time and consideration.

A. Tom,
Get a canteen of Tarn-X [affil. link to info/production on Amazon]. This is a chemical cleaner for brass that will remove the tarnish without damaging the contumely. Just dip your parts into a basin of this solution and use a soft bristled brush to scrub the recessed areas. Unless the surface is sealed in some manner (clear lacquer or polyurethane) the contumely will tarnish again in a few months. Good Luck!

A. We appreciate Tom Southward'due south help, but this information is not entirely accurate. The Tarn-Ten site includes this FAQ:
"Is Tarn-X safe to apply on contumely?
No, Tarn-Ten is not safe to employ on brass. This is considering brass is an blend of copper and zinc, and the acids in Tarn-10 effect zinc."
However, there is a dissever product chosen Tarn-X Brass Glaze.

A. Tom D: I accept tried Tarn-ten and have had little success except with silver...you might try liquid toilet bowl cleaner (toilet bowl cleaner [affil. link to info/product on Amazon]) which contains Hydrochloric Acrid...launder off as before long equally you apply it but it will definitely remove tarnish from Brass and copper. I apply it with 0000 steel wool [affil. link to info/product at Rockler] which won't scratch the metal. Needless to say (just I'll say it anyway) wearable Rubber Gloves [affil. link to info/product on Amazon] and don't breath the fumes. After you remove the tarnish polish with a Cape Cod Metallic Polishing Material [affil. link to info/production on Amazon] and watch the polish come up out!
Good luck...

A. It is possible that the original end was a lacquer, which was thin on the flat surfaces, thicker in the textured surface. Soaking the part in a hot element of group i solution, or trisodium phosphate [affil. link to info/product on Amazon] or Sodium Metasilicate or some solvent to remove this lacquer earlier attempting to shine it might assistance.

A. In that location were several different finishes used on those registers which had the bandage brass cabinets. Some were bright brass, and some were "antiqued". I retrieve antique is what you're looking for. Here'southward a process which will work, although it might all-time be done past a metal finishing shop.
Clean the brass panels dorsum to "as-cast" new. This will require some combination of organic solvents, stiff brushes, brass polish and buffing wheels. When perfectly clean, dip in a ii% solution of Liver of Sulphur [affil. link to info/production on Amazon] until dark brownish/black all over. Rinse, dry, then buff lightly over the high spots, leaving as much/niggling nighttime in recesses as you like. Finally coat with a clear acrylic.

A. I have been restoring brass cash registers for 20+ years and find that coating lacquered parts with 'Gunk' for well-nigh an hour before washing and scrubbing with a soft bristled brush in hot soapy h2o works great.

A. I restore brass NCRs as a hobby and polishing them is not an easy and fast process. First, every piece of contumely must come off. Next you have to get all of the dirt off by putting some water on it and Comet or Lime Away and scrub it with a tooth castor. Side by side you have to become the old lacquer off the brass by putting paint stripper on it and leave it on for fifteen minutes then cascade boiling h2o on elevation of it and, instantly later on, advisedly grinding it off with a powered contumely brush. I similar to utilize a paw held grinder with a brass wire castor in place of the grinder. Do not press also deep into the brass -- all you want to practise is take the lacquer off it. Information technology volition brighten up a ton, but that's not the end. Then with a bench buffer yous demand two different types of buffing abrasives. First vitrify the contumely with tripoli then terminate it with rouge. Both on unlike cotton wheels. End information technology all of with a sparse layer of lacquer and in that location you go. Hope this helps.

Q. I restored my first NCR 20 years ago. It was lacquered and I was told to purchase a Christmas wreath plastic container and fill it with water and a lot of Powdered Tide clothes detergent. Soak the piece like the back of the machine over night. To my surprise, it removed every bit of the lacquer without any scrubbing with no impairment! Endeavour it! Information technology Works!
I tin't seem to shine information technology without leaving dark residual in the engraving lines. I would love to find out how and I am so happy to pass along my tide trick!! No damage!
Where tin can I buy parts? I need primal rings and money flags to change from British pounds and pence! Besides what gets the green verdigris off? Cheers for your help and I have five to restore plus a nickel full size and nickel processed store. I also have 20 antique telephones to restore. I also have a valuable 19th century binocular microscope to restore that needs to be re-tarnished where the lacquer was worn off. Can I do this? I didn't realize that polishing this would devaluate it!

A. I worked for NCR in the 1960s and 70s. At that time the huge (25,000,000? sq ft) Dayton manufactory was full of obsolete parts. Millions upon millions of parts.
By the late 1970s mechanical cash registers were obsolete, having been replaced by electronics. The Dayton factory continued to make some other products, but was much larger than needed, so it was gradually demolished over the next 15-xx years. The demand for replacement parts was all but non-real, so AFAIK the parts inventory was sold for fleck.
An on line search will accept you to some hobbyists who may take some spare parts all the same.

Q. I have an early, circa 1900 NCR greenbacks register that is nickel plated over cast iron. Fortunately, the nickel is in good shape, but needs to exist polished to friction match a reproduction height sign that I purchased to install on the register [the reproduction is nickel plating over brass, with a gloss articulate coat]. I had to strip gold paint off the annals when I bought it; the previous owner had spray painted the whole register gold to make information technology look like brass! Luckily, I believe this had helped preserve the nickel end - which is now stripped, just has a non-shiny, irksome silver appearance.
I have polished brass, stainless, and copper before, but have never polished nickel - I know it is plated to an unknown thickness, and do not want to over shine or ruin the plating - and then need a gloss clear coat to preserve the polished finish. Advise volition be profoundly appreciated!

A. How-do-you-do Gary.
That's a cute slice of equipment but I don't think it always looked like your sign, and don't call up information technology's possible to polish information technology to that expect. For one matter, I'chiliad non sure that sign is nickel plated & articulate coated because it seems to accept the slightly "blue-ish" tint of chrome plating rather than the slightly "yellow-ish" tint of fifty-fifty fresh nickel plating.
Before trying a more than abrasive polishing or buffing compound, I'd suggest trying something like Barkeeper's Friend. Information technology contains oxalic acrid and a very balmy abrasive. Mild acids similar oxalic acid and sulfamic acid can dissolve nickel oxides (tarnish) without essentially dissolving nickel metal.
Luck & Regards,
