I'm working on an Ingraham half deadbeat movement from the Treasure banjo clock. I have it running fine (time train only at present) after much fiddling to find the sweet spot of the escapement, UNTIL...the spring expands enough to contact the post designed to force the spring to expand outward rather than interfere with the rest of the movement. How do I correct this? Ive tried lubricating the post to no avail. Suggestions, please!
