Great info. The safety razor was recommended for my LP12 . Need to find one for my Kuzma TT.
i like the concept of this DIY lifter, because it uses your existing manual lifter. But the mechanism looks big and ugly and complicated.

Just received the Tru-lift that I ordered Friday afternoon.

Merry Christmas
