Tonearm lift

Pivot or tangential, both cue up at the end. What's the diff?

What's the diff?

Maybe just the shape of the platform that support the armtube, since the arm is linear tracking it's not necessary to make it curved? 

I tried the type to automatically lift the arm at the end of play, like this:

I found out, for short arms, close to the platter, large platter surrounds like the victor tt61,71,81 .., there is not enough space to place it.

If the platter has no wide surround, perhaps it will work for curved, straight, but could a linear arm/cartridge mount trigger it?.

I expect, when I install my 12.5" arm, there will be space to fit one of these.

it arrived from Russia, I will be home late tomorrow, wed am I will know.

I just got one. Works the treat. They go fast and Brian is an aero space machinist. Most of his work is one offs for the military.  He can not make lifts real fast. If none of the stores have them call Brian directly at Expressimo Audio. If you have to wait for Brian to make one you will have to be patient. He also makes custom turntables and a tonearm with a radio controlled VTA ! 
Anyway, the design of this one is brilliant. It puts very little stress on the cantilever and there is no trigger mechanism to get stuck or wear out.
