Removed carriage to safeguard for moving. Now putting it back onto the bed. Forgot to mark the gear for proper line up, but I’ve done this before a couple of times, resolved that issue by trial and error. The main problem, and I don’t recall how I resolved it in the past: the nylon wheel […]

MoreNo. 4 Drive Chain
I’m slowly making progress on cleaning up my No. 4 and the other day I ran into a strange issue. Hoping others can shed some light on the situation. After re-timing the carriage I noticed it wouldn’t return all the way to the feed board. It seemed like the trip wedge wasn’t being pushed out […]
