front of lock secured with catch?

[Jerry V Lape]

Anyone have a good photo or diagram of securing the front of the lock with a catch that slips under a screw head or pin?  I need to use that technique and have not actually ever seen one done.

Taylor or Jerry Huddleston have both illustrated that in the past. Maybe Dan Phariss, too.

This is what you are talking about.






I just happen to have just been working on my first lock with a hooked front lug but need to get some pictures of it to show. I will post them later. You must remember to mount the stud with the width of the stud retaining screw head in place.  I just thought the stud should go here on the lock with out thinking through the fact that the head has to be wide enough to be capturing the hook as well as fitting into that front mortice area. You want a stout shank to the screw.

That's quite a trick, Dave, thanks for showing that.

You only think you made a mistake by putting the hook too far forward. The farther back you put the hook, the more slop you need under it so you can unhook it. You'd have to side the lock straight back in order to unhook.

You certainly will have to monkey with the proper screw head shape.

Note the relief filed on the original lock to let the lock plate pivot out of the mortise.

Good observation, Dan.  Only now I notice the underside of the toe of the lock is filed in a radius to allow the lock to rotate out of its mortise.

A long screw on a rifle can interfear with the ramrod at times unless the rod is offset. Some European guns had a small plate that was inlaid inside of the barrel channel to the side of ramrod hole and extended down into the stock at the location of the front lock screw.  The plate was drilled and threaded from the lock side in the location of the front lock screw. Then a hook headed screw could be threaded into the plate. Also if one desired to do so he could just use a plain metal screw in the front of the lock that was screwed into this plate. This type of setup is many times stronger than a hook screw that is just screwed into the wood because there is so little wood for wood screw threads. A double shotgun is different because the ramrod sits in the groove between the barrels and does not extend down into the stock so far. Comprendo?

[Acer Saccharum]

Thanks, Jerry, those are good options.

So the rest of the story with the long screw is that I turned this screw in the lathe getting it ready to  shorten the actual length of the threaded portion. but while having it unchucked to examine it and then looking for something else I dropped the screw with out knowing it and had to start all over again to make the silly thing. After I got the new one installed guess what I found. I cut back the end of the screw by 1/4" after using the extra length to finish chasing the threads up through that shank section just below the shaft of the lathe turned section.

Thank everyone for the great response to my request.  I believe I understand how to install this, executing it may be a different issue, except for one term used.  JerryWH, I cannot find a description of a "hook head screw" which makes sense to me for this installation.  Please further describe this type screw?

 Here is a sloppy scetch.

[Jerry V Lape]

JerryWH, Thank you for the explanation and diagram.  I was envisioning the small inletted plate but with a screw from the lockplate to the small plate - with some sort of speciaize screw operated from the exterior of the lock plate.  Did not understand there were two special screw involved.

Jerrywh, it may be sloppy but it is wort about 10,000 words.  Thanks for taking the time to draw and post!

Thanks for posting the drawing, Jerry.  Even I can understand it!
