Help pushing mainspring into barrel please, again

Question

Hi All

If you've read my other posts you know I'm failing miserably with mainsprings.  Most of the issue is not having a winder (I'm looking).  I'm trying to push the spring from the donut directly  into the barrel.  The first time I did this it went effortlessly.  I've since had trouble.  This is a Seiko 6119A automatic.  I've previously failed by attempting even insertion pressure across the spring.  The bridle hung up and then the spring went airborne.  I can't hand wind it.  I've learned from members that the outermost wind needs to go in first.  My question is what to use to push it in.  I've tried peg wood on another but that results in wood debris.  I've tried a screwdriver but I'm afraid to damage it.  Any suggestions?  Is this even doable or is a winder needed?

Thank you

Charlie

Press the ring down on a flat surface so the side of the spring that goes in first is sticking out at maximum. Place it in the barrel. Hold the ring down with your ring fingers, while pressing on the end of the bridle and also at the perimiter of the spring 180 degrees away. Getting the spring in the barrel, while in the ring, is 1st key, holding the ring down while pushing is second key.

That did it.  Though, I made a slight mod to the procedure.  I placed the donut over the barrel and secured both to the bench by running strips of strong packing tape of the edges of the donut.

Good old creativity at work. Kudos to you.

Yes, figuring out ways to enlist the ever-absent, always needed,  third hand comes in very handy. I found 11th-15th fingers needed to get set-spring in place on a 7 3/4L Peseux. I placed my screw-drive movement holder, with movement in place, into my bench vise and it worked like a charm. The holder had nice squared sides that made it facilitate itself nicely to this purpose. Congrat's on getting that spring in with a little ingenuity. Cheers.

    • Well, this months pick.  
    • Very good work. Happy to see all the pics and your project.
    • New to watches, I would venture a guess.  Since it was behaving as expected for a full 8 days, then started to switch the date incorrectly, would imply something broke, or became misaligned, or loose at day 8.  Obviously I haven’t a clue, but it’s fun to speculate! would appreciate and update when you figure it out.
    • A gold plated champagne dialed  "Kudu" joins the club. This 17 jewel Swiss front loader needed a service, a crown and stem to get it running. It also benefited from a complete valet, and a crystal polishing session. Finding and fitting a suitable stem was the most tricky part, since the original had broken off right at the edge of the base plate, so extracting without stripping it down was a non starter, and finding something to match the broken stub in my "pile of random stems" took a fair bit of scratching around and experimenting. It looks a whole lot nicer in real life than it does in my rather badly lit photograph. The strap was borrowed from an HMT Kohinoor which is hopefully going to be the next patient up on the healing bench.
    • Nice to be a part of the group. I lurked around awhile go. Just finished level 2 of Mark’s course. I’ve been a member of the NAWCC for many years, and taken their onsite pocket watch repair course, and repaired many since. I also restore old clocks, both the case and movement. Picture attached is of a recent restore. This clock is an 1894 Ansonia that was ready for the trash pile.  I am also in the midst of building a skeleton clock from brass stock. I use a Sherline lathe and mill to turn the wheels and cut the teeth. It has been many years in the making, but has taken its first ticks this year. looking forward to more learning and more work on watches. Mark has a great and easy style for learning.  I’m almost finished servicing my first automatic watch I ever bought, a Tissot embedded with an ETA 2824-2. The mainspring just arrived.
