John,
Johnie has highlighted a few of the features that Albert Johnson would sometimes add to Emmons PP guitars. I borrowed these two photos below from Johnie's "for sale" post.
The photo above is a close up of a pedal cross bar crank that Albert designed and had made to take the place of the stock crank that the original part has. The 3 holes provide a choice of leverages that effect the throw of the pedal. The middle hole is close to stock and the other 2 provide a shorter or longer travel that equate to a heavier or lighter pedal feel. Also, the the holes have an advantage over the notch in the stock crank. Using a hole keeps the pedal rod hook securely in place. The notch relied on a return spring to return the crank to the pedal bar in order to retain the hook from coming out during play. Using Albert's aftermarket crank allows for more choices in leverage and if desired, removing of the return spring. Removing the return springs result in a slight decrease in the amount of tension for the pedal.
The photo above shows a pull rod guide bracket that Albert used to fabricate and install. This bracket in used to support and guide the pull rods in lieu of extra bell cranks and their swivels.
If you look closely at the Johnie's underside photo by the changer, you'll see that Albert used heat shrink tubing to stabilize the raise hooks. This also lessens a bit of noise underneath while playing. I took that idea myself and have been using it for years.

Thanks Lynn
I have thought about using shrink tube for the rods if I use smaller diam rods (currently 1/8"). Most shrink tubes I have seen in electrical shops have writing all over them. |

I like the rod guide bracket and heat shrinks. That’s 2 features I don’t currently have of the ones mentioned. What size heat shrink works best?
Thank you for any help.

| There's also a push rod guide for the lowering rods that further simplified things underneath. Clean, clever innovations. |

Marty,
I use 3/16" tubing cut to 1 1/2" segments.
Peter,
Yes, I've also seen those drop rod guides used very effectively as well.
