Project description
I have inherited a manual typewriter that has been sitting in a closet for roughly thirty years, and I would like to bring it back to full working order rather than display it as a decorative piece. The machine is a desktop model with a QWERTY keyboard, and the overall frame and body appear solid, but the internal mechanism needs serious attention.
The main issues are as follows. Several typebars stick together when multiple keys are pressed in quick succession, which suggests the segment slots are gummed up with old oil and dust. The carriage does not return cleanly to the left margin — it catches partway across and needs a manual nudge to finish the movement, so I suspect the mainspring or the carriage rail needs cleaning and possibly re-tensioning. The ribbon vibrator is bent slightly out of alignment, striking the platen unevenly, and the ribbon itself is dried out and needs to be replaced with a fresh spool of the correct width. A few keys are misaligned vertically compared to the rest of the row, so the type impression is uneven on the page.
What I am hoping the specialist will do:
1. Fully disassemble the typebar segment and clean each pivot point with an appropriate solvent, then re-oil sparingly with instrument-grade oil.
2. Inspect and service the carriage return mechanism, including the mainspring drum, draw band, and escapement, so the carriage advances one letter space per keystroke and returns smoothly at the end of the line.
3. Realign the sticking and vertically offset keys so that every character strikes the platen at a consistent height and pressure.
4. Replace the ribbon and check the ribbon reverse mechanism so it automatically switches direction at each spool end.
5. Clean and lightly polish the crinkle-finish body panels and the platen rubber, without damaging the original decals or the manufacturer's badge.
Please include in your proposal: your experience with mechanical typewriters specifically (not just general small-mechanism repair), photos of at least two prior restoration projects, an estimate of how many hours the work will take, and whether you work on-site or require the machine to be shipped to a workshop. A written before/after report with photos at each stage would be appreciated so I can document the restoration process.
