It's theeighties granite, Sledge 77 a bus got a lot right.

When they put it together, we can start with the five millimeter thick, hardened steel outer lock body.

Inside of that is a hardened steel sliding carriage, and that's where you put the disc brake rotor, and holding that carriage closed is a ball bearing locking mechanism.

Now, with respect to that mechanism, I do have to note a problem.

The locking ball on the back side is missing on this one.

It does stay locked because of the other ball, and I have no reason to believe it's a widespread issue.

However, given that this is a ball bearing mechanism, not putting one of the balls in is a significant QC failure and something a bus may need to look into.

Now, securing everything is a bet's X plus disc detainer core.

It has eight discs, each with false skates and a disc locking system, preventing any of those disks from rotating until a key is inserted.

It's a fairly tricky core.

So let's see what it takes to pick it open.

The first thing we need to do is rotate all of those disks as far clockwise as they will go.

And as I said, we have a disc locking system.

So I'm reaching all the way to the back where those locking tabs are putting a little bit of torque on that tool and just jiggling it around until those tabs let go.

I've now rotated all those disks to where I want them to be.

So we're gonna take out the pick that Bosnian Bill and I made a pickup disc number one and get to picking.

Okay, I'm going to start in the back.

Most of these X plus cores bind from the back.

Okay.

Nice click out of number eight.

Nothing on seven.

Six.

Little click on five.

Click on four and a fair bit of movement on the core.

I'm for three.

I think three's in a gate.

So is number two going back.

Three.

Okay, Four.

That was binding.

I moved him just a little bit of him.

A little bit more.

Harry, go for field set.

Nice.

Wide.

True gate moving on.

to 55 is binding.

Gotta click there and it's still binding.

Let's move him a little bit more.

There we go.

Five.

Feels like it's set.

Number six six feels like it's in a gate number seven.

It's a little bit of movement.

They're gonna leave him alone.

For now, Number eight is definitely binding.

There we go.

That was the last disc.

So as you saw, it's a pretty tricky little pick.

And putting aside the quality control issue this particular one has, it's a lock that I wouldn't hesitate to use myself.

In any case, that's all I have for you today.
