I just got this idea in my head and it had to come out. I figure if I can't properly 'visualize whats going on' by what I feel, why can't I SEE what's going on? That alone would be great for associating What I feel 'those ever so slight clicks and pressures' with what is happening. and lo and behold, I looked at my favorite lock, and this is what happened......proof that I should never be left alone around any kind of tools when bored..
Until I can borrow a better digital camera than my crappy 10 dollar one, these pics of the modifications will have to do.


Yea, it's ugly, its even more ugly when you can see it clearly, but it lets me see inside of the lock as I pick it, which is a great help for people trying to associate what they feel from the pick with what's going on.
If I ever figure out how to do this more cleanly I may post some sort of FAQ, but for now a quick rundown of what I did'll do.
Materials used:
Lock - Its an ilco...it says 150 Ilco on the lock housing. I disassembled it and re pinned it the same way it came so I could use the key on it. I chose this one due to the fact that it was free(!) and the sides of it were actually flat with only the very front and back of the lock being round.
tools:
-flat rectangular file to smooth out the grooves cut out of pin holes
-Dremel tool with one of those big grey/black cutting & grinding disks. also used a grey grinding stone to polish it and remove burrs
-Popsicle stick. Yes a popsicle stick. I used the dremel tool on this to cut it down to the perfect size for a cover to depress the springs.
-the metal ring the lock's keys came on. I bent it into a C shape, then drilled a small indentation in the top of the wooden piece and the bottom of the lock. By putting the ends of the home made 'C' clamp in these indentations, I made a secure means of holding the wooden cover over the springs without obstructing the 'window' that I made in the side of the lock.
VERY quick run-thru of what I did:
1. disassembled the lock. put springs, pins in a safe place.
2 . use grey cutting/grinding wheel to carefully grind down the side of the lock, stopping just above where the pin holes would start.
3. Did my best to flatten out the ground down area, making it all nice and pretty like. failed miserably.
4. VERY(!) carefully cut slits down into the pin holes making sure not to cut the slits too wide, as that would cause the springs and pins to pop and fall out.
5. did my best to de-burr and clean the thing. slid one of the top pins through each hole to make sure that there were no obstructions.
6. took the lock..err..core? and carefully repeated steps 4 & 5(using bottom pin) on it.
7. Replaced core, it stuck. after looking at the inside of the lock housing, I found a burr I missed. Had to get at it with a tungsten steel grinding bit.
8. placed key in passageway, placed bottom pins in the core's pinholes, making sure they lined up right.
9 . turned key to line up pin holes in core& housing. Replaced bottom pins & springs. Attached cover.
10. removed and re inserted key to see if I had totally destroyed my favorite lock. It worked! I now have a lock that will better help me associate what I feel with what's going on, and I can re pin the lock by turning it counter clockwise!
All it lacks is a good lubing with graphite. It kinda sticks at times.
