Anyone know a good Akiyama Mechanic? Or how to set delivery gripper tension?

[ScotJ]

I'm looking for a good Akiyama mechanic that I can bounce some questions off of.

I'm trying to set the grippers that run from the last unit to the delivery.

They seem to be quite weak in spots, and though each gripper is spring loaded- the entire shaft that it rides on is also spring loaded which forces all of the grippers down. I've come to the conclusion that this needs to be give more tension - but can't figure it out and don't want to screw it up to badly.

Any ideas - or people I can contact?

Hi Scot:

As I recall, if you're on a bestech or probably even a Hi Ace, (I think they're the same) "preload" the entire gripper bar with a couple of sheets of coated 60# under the overall bar stop and set each gripper evenly with only finger pressure holding it to the pad. Loosen screw holding the gripper to set pressure. Then, remove the preload and check pressure on the individual grippers as well as free "action" to double check.
Good Luck...

One more thing, we've had the pins holding tension on the springs sheare off before, so those might be another thing to check. The bar needs both springs to work well, so if one is broken... Also, the cam followers. They should be free rolling with no slop...

Agree with the above post, but I set mine with a thicker stock to give it more of a bite. Also I've had better luck setting the middle grippers and moving out.

surley if you set with a thicker stock it will have less bite?

Thicker stock under the bar stop.
