I recently picked up a Remington Standard 12 at a thrift shop. Instead of guessing at why it isn't advancing, I’ve spent some time digging into the mechanics and have successfully isolated the exact points of failure keeping this machine from being functional.

Here is the diagnostic breakdown of what is working versus what is completely seized:

What is Functional:

• The Carriage Rails & Bell: The carriage slides smoothly along the rails when the release is held. Manually tripping the rear trigger lever produces a loud, clear ding, proving the bell mechanism itself is in perfect shape.
• The Drawband: The backspace key successfully pulls and moves the carriage, which confirms the drawband is intact and properly connected to the carriage.
• The Key Linkages: The keys and spacebar depress smoothly. They are successfully pulling the internal linkages, which simply stretch the yield spring because the escapement wheel is locked.

The Confirmed Issues:

1. Frozen Crescent Arm (Escapement): The crescent-shaped escapement arm on the side is completely seized. It is gummed up with 90-year-old hardened grease and is refusing to pivot, acting as a permanent brake on the escapement wheel.
2. Gummed-Up Mainspring Drum: The carriage has zero passive tension and sits dead when released. Since the drawband is intact, the mainspring drum is clearly choked by oxidized, hardened grease, preventing the spring from pulling the carriage.
3. Seized Ribbon Reverse Linkage: The flat metal ribbon reverse linkage bar running front-to-back under the spool is heavily rusted and completely frozen, which has locked up the entire ribbon drive system.

I have sewing machine lubricant and a new ribbon on the way to tackle these exact spots. I just wanted to share this diagnosis with the group, but feel free to let me know if there are any secondary symptoms I should look out for once I get these three main areas freed up!

I just found a Remington Standard 12 at a thrift shop and want to repair it to the point of being functional. So far, I have sewing machine lubricant and a new ink ribbon on the way.

My main issue right now is that the carriage does not advance. Whenever I press a key, the carriage doesn't budge. It still has old ink ribbons spooled on both sides (which I'm assuming have been there since the 1930s), and the ribbon mechanism isn't moving either. The space bar also seems dis functional

I'm completely new to this and not sure how any of these mechanisms work. Any advice on how to get the carriage moving or where to start troubleshooting would be greatly appreciated!

I currently have a Ryzen 5 5500 and an RX 6600, but I want to get into 1440p gaming. My motherboard is only a B450M, and my PSU is a Thermaltake Smart BX3 Pro 650W. I'm looking to upgrade my GPU to either an RTX 5070 or an RTX 5060 Ti 16GB. My only worry is the power supply. While a 650W PSU is recommended for both the 5060 Ti and the 5070, I’d rather be safe than sorry. (I will deal with the CPU bottleneck for now.)
