Hi All,
I have a 15-2 VHB and several years ago I took it apart to clean it and after
reassembly I pulled the hammer back and did a couple of dry fires. One DA and the other SA, everything was fine and I put it away.
When I came back to the table I noticed that I had found a small plunger. I
had cleaned several guns that night and really wasn't sure if it had come from the DW, but was pretty sure. At the time I didn't have the time to take it apart again so I put the part in a small medicine bottle and put it in the safe with everything else.
Flash forward 6 years and a move later and it's nowhere to be found. I took
it to the range and since I usually shoot SA I didn't notice anything odd, until
I tried a DA shot and the cylinder rotate about half way and the hammer would not cock back. I rotated the cylinder into position and cocked the hammer and the cylinder rotated to the next cylinder and fired of course.
Well for better or worse I shot it that way about ten times using SA. Here lately I noticed that the timing was off and even in SA the cylinder is stopping before it's supposed to, like it is not being pushed far enough by the little spur thing that rotates the cylinder.
I bought the small parts kit from EWK thinking that I saw this piece in the
kit, but alas it was not to be, although changing all those springs isn't a bad
idea at this point.
So here is the problem, I am missing the plunger that goes into the hammer to push that little pawl type part that allows DA to work. (feel free to correct my parts descriptions.)
Failing that does anyone have the dimensions for the plunger that goes into the hammer assembly, so I can spin one up on the lathe?
I have never taken apart the cylinder and am going to search and find outhow to take it apart, clean it and replace the parts I have for it. (I did find the info the other night just got to find it again).
Sorry for the long post, but better more info then not enough I always say when troubleshooting.
Thanks in advance,
Jeff

First 
to the 
. Sounds like what you need is the strut plunger and probably the strut spring. Check the FAQ section on the right column for where to get parts. A few bucks and UPS should fix you up. good luck and keep us informed.

I think Steve's got it, from your description. Check out THIS THREAD, Shoot has some nicely detailed pics of the 15-2's innards. You should be able to spot your missing part there & chances are that one of us may even have a spare part for you.

Which plunger is it ? Bolt plunger part #36 or strut plunger #45 ?
Here's a diagram:http://stevespages.com/ipb-dwesson-w142152.html
Either way you can get it for a couple bucks here :

It's the strut plunger #45. I made a new one this morning and here are some pics. I made it a little long, since my parts strecher is in the shop. Here are a few pics of what I did. I ended up doing it from memory, so……I am not sure how long it is supposed to be. It fits great but I don't have my pistol here at work, and I think I may need to shorten it. What do you guys think?

LB had it right (not Steve). Steve had not yet had the opportunity to offer a resounding "duh?" and a blank look, his usual contribution whenever the problem gets down to the little-bitty parts
I went to a bookstore and asked the saleswoman "Were is the Self Help Section?" She said if she told me, it would defeat the purpose.

Well it looks like I made it a little long and this keeps the trigger from resetting. I'll have to grind the end down a little. It's going to be kinda interesting since I rounded the plunger more than the stock one which changes the the point of force a little. We'll see how it goes. If anyone has a suggestion let me know, I am not a gunsmith, but I can find my way around some tools, so if I am doing something wrong please let me know.
Thanks,
Jeff

Well that worked out well, got the trigger to reset now to put it back together and see if that helped with the timing issue I was having as well.

Okso it's all back together and everything is working fine, although if I tighten down on the sideplate screws the trigger won't reset. I probably need some lube and to clean it. The machining on these things seems to be like they were done with a Harbor Freight tabletop mill using broken endmills with the stock out of balance. (I have done this before, lol).
So for now it looks like everything is working again if I pull it in DA it fires now and resets and if I i pull the hammer back quickly the cylinder times just fine. Probably need to clean the cylinder too.
I am going to go ahead and polish the internals and slick it up a bit and install the EWK spring kit I got since it seems to be working correctly.
Am I missing anything?

Sounds like you are making progress. A common problem with the side plate causing problems is the hand spring. Make sure it is in the little groove on the back of the hand and not around the hand. May not be your issue but is a common one.

D'oh! 
Crap, I was distracted by the stainless bling in the sig pic, or it was just too early in the morning...take your pic.
Sorry, LB.
Jeff, glad to see that your fix worked well. And you're right about the machining marks...the marks inside my DW's vary widely, I can compare several guns from the same approximate era & some will look nice, while others look like the tool being used was definitely getting worn out.

I haven't had a lot of time to mess with it lately, but it seems the sideplate is too tight and is causing pawl that engages the cylinder to get stuck. When I get more time I am going to clean everything up.
I did end up making a barrel nut wrench to get the barrel out. I was able to remove the barrel and chucked it in the lathe and ended up drilling the bullet out using an 8" long 1/4" bit, but the rest of the bullet is still stuck in the barrel. I had a friend say I should melt out the rest with a torch, but I am concerned that I may damage the barrel that way. It seems welded to the inside of the barrel. I have tried beating it and that's not working. Other than buying a new barrel what else can I do?
Thanks

Have you tried soaking the barrel in a 50/50 mix of ATF and acetone; a great penetrating oil , let it soak overnight and try tapping again, then repeat for another 24hr. With the core out the bullet should colapse on itself and move out, use a relatively heavy hammer, soft(brass)rod and slow firm taps. If all else fails, barrels are still available.
