different type of security pin

[critmass235]

Has anyone ever heard of a security pin thats the opposite of spools( gets fatter in the middle not thinner ). Instead of false setting it would false bind , making it drop the other pins behind its setting order( not binding order) it would take much just a few degrees to counter rotate and drop all your previous set pins. and it would feel like a normal false set but when you try to back out and set it. i thought of this when trying to have in depth understanding of picking and after reading a little about safe manipulation ( finding high spots or low).

I think I can picture what you are saying a top pin shaped like that would want to fall from very slight counter rotation. You should make one and throw it in with some regular spools see what happens and then let me know cause now you've got me curious lol

[critmass235]

thats what i was thinking ( the spools) im later going to try to use a drill as a lathe with some zirconium welding rods i have laying around to make some. its ok for cutting in but probably not as easy for this

[GWiens2001]

You are thinking of barrel pins. The shape is like this:

...-----
./.......\
/.........\
I..........I
I..........I
I..........I
\........./
.\......./
...-----

ASSA V10 uses those, see page 18 of this pdf: http://toool.nl/images/f/f9/Cutaway1.pdf

lol the technical term is sneaky pins edit: this is actually from page 9 so wrong page but still funny

[critmass235]

i think that sneaky pin he ment the key pin that would false set on a over set overset

[Paleo123]

Yeah I know just the term sneaky pin gave me a laugh.. I also might have been self medicated last night which didn't help

[critmass235]

wouldn't a lock with multiple tapered serrated pins give both barrel and spool(and a really long setting order) effects

[GWiens2001]

Use a drill and file to make some pins like that and let us know!

For many years Yale used bottom pins that were round on the bottom and had a taper near the top. These with original mushroom top pins created a nasty sneaky pin combination.

first got to unpack and find my tools(i used a dremel and file for my first homemade sec pins) but the goal is for them to look like xmas trees

ASSA makes some interesting looking security pins some of which might be what your thinking of.

If you look in the Buy-Sell-Trade section there is an ASSA cutaway profile cylinder for sale with these pins & you can see them.
