I Want JACO designs lock plans

[victorfox]

Hi friends, don't know if here is the correct place or the gunsmithing subforum.

I got an itch to try my hand at a homemade muzzleloader pistol, found a nice section of free .36 steel tube, and that would make a decent smoothbore barrel. Main use would be cheap plinking in the countryside where a friend has a small, hidden place, where we can shoot without being disturbed (i'm in brazil and all things firearms here are horrible due to gun control laws).:neutral:

Did some searching and researching and found the plans for the JACO horse pistol, but I can't figure how to build the lock. :???:

Also found another forum where a member built one and roughly I can understand how the lock works, but I'm a loser at "guesstimating" dimensions. The building seems to be quite simple, but the dimensions are enerving me...

I would be more than happy and grateful if someone could provide me a link or a very cheap source of life size lock plans (best if free as in free beer). :mrgreen:

Thanks in advance.

Thanks! I think the western pistol will do! Cutting and gluing the parts on steel will probably make it. Thanks!

See if you can get a copy of Colin Stolzer's book on making a homemade lock. It's inexpensive and makes up into a nice percussion lock.

Making an underhammer "double action" with no lock at all works well also for a fun pistol. Been wanting to make a 12ga. shorty type pistol like that for some time now, super simple to stick in your pocket.

Nobade underhammers are very interesting indeed, gonna check it.
