I just started trying to pick this. It's a really cool lock. Dual sidebar, 8 pins with false gates. It'll keep me occupied for awhile. lol

If you scroll down about halfway in the opening post in this thread, you can see what is going on inside the TuBar lock.

I need to get me one of those for my collection.

Don’t see them much around here!

I see them on Gas Pumps, Love a go at it. Won't do it on a pump.
Wonder if you couldn't make a Pick with 8 Allen Wrenches, Thick plastic strip in the middle, then holes in clear plastic with the 8 holes. The Allen's would also be the Tension

I've tried to make a custom pick with 8 L wires like the one you describe, but it was not easy to feel the pins like I did with the single pick. So I went on SPP.

It's a great lock to pick, don't give up!

Cheers

Know what you mean, when I first got Tubular Pick, tried SPPing with it, , easier to pick without Tubular Pick, and do 1.by 1,.
Then I learned Impressioning with the Tubular, so much better, Faster.
Did make me think an Impression Pick for the TuBar, likely won't? Work due to the sidebars, but who knows, you would have never thought to use the Tubular pick to Impression.
Anyone here try to SPP with the Tubular Pick?. And how long did it take to.discover Impressioning with one since they first came out.

Those cutaways are really beautiful! Like stratmando, I've seen these on gas pumps, but I had no idea they were anything other than a variant of the standard tubular lock. What a cool patent.

Like to see someone make a Bump Key and try.
Have see Ace II Tubular opened with a Bump Key on YouTube

They use eight one-piece tumblers with two sidebars. So the only 'bumping' that might be feasible is removing a blank key while turning pressure is maintained on the plug. Then some of the tumblers have a shallow second (or more) groove. So this would make picking more difficult than an ACE or similar. But the LockPickingLawyer can still get it open in less than 10 minutes. However the increase in security of Tubar over ACE would seem a sufficient deterrent to theft.
But compare Tubar with BiLock. They are both two-sidebar cylinders. They are different in that the tumblers in the Tubar are easily accessible for manipulation (as ACE) whereas the BiLock tumblers are in two longitudinal rows with the usual access issues for picks. So BiLock seems one-up on Tubar. But at least BiLock does not have tightly warded paracentric keyways.
