Lofrans Tigres mainshaft bent key extraction
|
Tim Melbourne
Anybody know a clever trick to extract a bent key without trashing either the windlass mainshaft, its bearings internal to the housing, and/or the gypsy?
I've tried everything I, and various interested Seattle parties, can think of, no dice. See photos below - mine (bad1, bad2.jpg) and how it ought to look (good.jpg). And if you haven't lubed your gypsy of late... Thanks in advance. -Tim Melbourne SM2K #306 |

There comes a point where it gets really hard… and good for you on recognizing that lack of lubrication of the clutch surfaces is the cause.
A cold chisel (and hammer) set close to the base of the key is my go to solution for this. if the key way itself is damaged, you can have a new one cut on the other side of the shaft at less than the cost of a new shaft.

Hi Tim. I would try a 10mm pin punch on the side of the key and bonk it solidly with a heavy hammer
Note I said bonk not bash
Failing that I would cut or grind away the exposed portion of the key. This should then allow the 2nd half of the gypsy to come off. Then what remains of the key can be lifted out of its channel.

... and another way to skin the cat is to get a new, slightly larger key and grind or sand it down to fit correctly. I just did that with my main drive shaft where the key had gotten wobbly in the key way. Got a replacement key for a couple of bucks on-line, used my angle grinder with sandpaper to grind it to fit, and now it is snug as a bug.
