Yep, most things I try take a while, sometimes they don’t work either. I try to learn from the things that don’t go according to plan. A teacher I really admired had an adage “he who never made a mistake never made anything”. Though more often recently I’m thinking “you should have known that wouldn’t work”.
I used to replace worn pawls but they’re now difficult to get and expensive. When they were cheap and readily available it wasn’t worth fiddling about. I could make replacements myself but that’d take a long time. I may yet do it if these redressed pawls don’t stand up to use.
I’ve done home electroplating in the past so I could plate them to provide rust proofing. I’m working on a few things at once at the moment so any further experiments with mowers will need to wait. I do have some old tool parts that need replating so I could potentially do a batch.
