Making a practice cylinder
And its not really a tut, just an idea.
The idea is to knock out the bottom plugs on a regular cylinder, and drill troughall the chambers-
I used a trioving oval cylinder...But this can obviously be done to diffrent types of cylinders
I got the idea from the trioving dp cylinder, they do almost the same as i do,, but they thread the end
Just drill a hole trough all the chambers, and use something like a nail or drillbit to keep the chambers closed
This way you can just remove the drillbit/nail, when you feel like repinning the lock
Here are some pictures:
