...Undoubtedly more than you want to know about that First Series Colt Woodsman Match Target that moved in a few weeks ago, the one who didn't bring a magazine along. So sue me.
I mentioned in the second post down that I found an old High Standard HD mag for it, along with a similar empty body. I claimed I could make the follower and find some sort of workable spring.
Half done in less than 45 minutes.
The left follower is the new one. It looked correct and measured correct. Just to make sure, I installed it in the mag with the spring. Works fine.
Two complications remain. A spring could turn up in one of my "miscellaneous" boxes during my next paw-through. If not, almost any from a gun-show-junk .22LR magazine should be adaptable.
The retaining pin will give me more trouble. JMB designed it as slip-in. The groove under the head holds things together by engaging the body tin. There's no lathe here, so I'm leaning toward tapping the hole for a 6-32 machine screw. Might work. Might get a better idea.
The new follower began life as a steering arm from a junked-out Dixon ZTR42 mower. Most of it went to Ken's iron pile, but I squirreled away a few likely looking bits of steel for just such an emergency gun repair. Because I live a pure and virtuous life, the handle happened to be the exact thickness of the factory follower, saving me some tedious surface grinding.
Tools involved: Makita angle grinder. Baldor bench grinder. One-inch vertical belt sander obviously built by a Mattell subsidiary. Twelve-inch muslin polishing wheel on big old 3450 rpm Craftsman table saw motor. Chinese drill press. (Twenty minutes after you drill a hole you want to make another one.) Couple of mill bastards.
Technique: Use the factory part for a pattern. Cut your new one a few thousandths oversize. Trim to fit. (That's what the bastards are for.) Shine her up a little.
