Abloy Protec Padlock (PL330N) cutaway

[mh]

I finally found some time to do another cutaway:



An Abloy PL330N.
You can see the return bar in action, as well as the little notches that block the discs when tensioned via the Zero discs:





I also cut the other side that shows the actual locking bar, but that's of course normal rotating disc tumbler stuff, nothing special...



And I put a transparent disc in place of the bottom profile disc, so you can see the control pieces that block rotation of the plug while the key is not fully inserted.



I guess I need a new signature now...



Hope you enjoyed it.

Cheers,
mh

I think an end mill is indeed the nicest way (and the easiest) to cut this lock. But there are many ways to skin a cat...

If someone want's to try it without a milling machine, a hacksaw and a rotary tool (e.g. a Dremel) and a file will also work - like the ABUS Plus cutaway in my current signature.
Just leave enough material in place so that the upper and lower part still hold together properly, maybe cut both sides but at an angle, like this (view from the bottom):

thats a nice one!

I really wish I had the spare cash to get my self a mill/lathe....

Wow, nice job on the cutaway! Pictures are also nice and sharp.

[Tuniz]

now that's a great cutaway!

are you able to actually rotate the discs and actually pick it?

guess you need a special tool for it though...

[arris]

woah that is awsome,

very very impressive, some skills you have,

[mh]

Thanks, I'm glad you like it

[greyman]

Well done mh. Those disc-blocking grooves are evil!

Lovely cutaway

Didn't realize the 330 came with the protec cylinder? always thought it was the 340. Learn something new every day

I've got 3 x 330 classic pads now....I pick them up on ebay for a tenner a time and as soon as the yare through the door the grub screw is drilled out so I can dismantle the cylinder.

I've marked mine up totally different to yours to be routed though.....Instead of a deep cut in like you did, mine skims about 3 - 4 mm from each side just enough so the locking bar can still work without falling out. Its a bit of a trial & error thing though, & i figured that cutting a bit at a time is better than going for the whole lot without knowing of any problems that may arise.

I've got 2 more here which will get the treatment in due time.....will definitely have one deep cut like yours now i've seen the result

A single-sidebar rotating disc tumbler lock such as the Abloy Classic (*)would be somewhat comparable to my current signature lock - on the ABUS Plus I did one deep cut:

BTW, there are some nice pictures all collected in this thread:

(*) I realize of the course that the Abloy Classic is THE single-sidebar rotating disc tumbler lock...

mh, I have birthday on 30th of March, so you have 15 days to pack it, ship it, and still be alive

Nice work man, very nice work! So did you use a mill or did you do milling on your lathe or did you just use Dremel on this one?

[mh]

a 10mm end mill in my mill (the one that sits next to the lathe), and if I had taken more time, the surface would be even nicer -
last week I saw a lot of the Protec cutaways Julian Hardt milled, those have near-perfect surfaces... The tool he developed together with a machining expert to hold the plug while cutting was also quite impressive...
