Making nice practice locks for little or no money

Making nice practice locks for little or no money

Postby thertel » 10 Aug 2004 4:05

So today as I waited in line at the post office for an hour only to have to return home because I forgot logosys's mailing address. But in this hour I doodle an idea for affordable do it yourself clear practice locks. Now I have not started to make one yet, but I will start as soon as I get all the parts. So here it goes

PARTS
Lexan Cube
Drill press
Drill bits
polishing bits
very sharp pointed marking tool
lock that will be made into the practice lock
Lock Cylinder, preferrably 2 cus You might ruin one.
Pins
Springs
Good Calipers
acetone (optional)



First take the time to measure the lock and trim down the lexan so that the cylinder will fit right without sticking out and so that the area for hte pins is the correct height so that the spring will behave properly.
Okay so now you take the calipers and measure the inside of the lock cylinder. Now I cannot stress enough the need to measure three times just to be sure, also account for the fact that the front of the cylinder is wider and will need to be countersunk. Next mount a bit of the correct size to the drill press and drill the hole into the lexan. verify the cylinder fits properly and is able to turn. Now mark the pin hole into the lexan and find the center of cylinder and drill out the pin holes. now take the time to polish and smooth out all the holes you've drilled so that hte end result is pretty, if you have acetone use it on a cloth cus it will take off the top later of the lexan and help polish it up

Now you are ready to begin assemly, simply insert the cylinder and apply the c clip to the packand then load the pins into the lock followed by the springs and then cap the spring holes. To do this I would suggest filing a grove so that the standard pin cover fits.

And there you have it a homemade practice lock in no time at all. I just ordered a Mul T Lock rim cylinder so that I can try learning to pick Mul T locks.

Now as I have said already I have not tried this method yet but the principals are sound but your mileage may vary greatly depending on your tool skills.

Well everyone let me know that you think and I will try to make one this week before I start making my new picks.

well it was geared more towards a do-it-yourself project, but I guess that after I streamline the creation a little more I could look into the cost of selling these, but depeding on the particular lock used it could get costly.

So far its pretty cheap though, I got enough lexan to make about 40 locks for about 3 dollars from a lexan suppliers scrap bin.

I have a mul t lock from ebay that i paid 10 dollars for but its taking forever to get the drillings right so that everything works right. I imagine its much easier with a kwikset or a schlage and all you really need is a rim cylinder I'd be willing to bet they can be made for less than 15 dollars each perhaps less than 10. I'll probably start on a kwikset today and put the mul t lock on hold cus I'm getting frustrated.

I will post pictures on here when i get it working.

I have a SolidWorks model and full technical drawings of a Schlage SC-4 Mortise Cylinder if you need them...

I'll do it as soon as I get back to Aggieland. They're pretty accurate, but might be a little errant, seeing as I need new calipers. They'll definately do the job though.

What format do you want the drawing in? Do you have a copy of SolidWorks that you can use to read the drawings or do you need them in DWG/DXF?

I realize this is an old thread, but if you're still listening, I'd love a copy of the model as well - I'm trying to get my hands on some accurate, detailed models of locks... (I use Autodesk Inventor, personally, but solidworks is compatible)
