    I gonna make a new video I think, there is not enough info on how to operate in its normal fashion and I'm sorry for that. If you centri speeds up there not enough tension on the needle. The side grooves are for extra small bands not your primary band location. That area is to close to the needle bar for tension support. Using that placement will let the motor spin without capturing the full centrifugal force. In a sence the weight is spinning so fast it can't pull in Etheir direction. The more tension on the bar the more the weight will react to g forces in return giving you the correct stroke. Running your centri to fast will defeat the purpose of capturing the gforce we are looking for. I'm gonna make a whole new video making this technology more understandable and stress more that this not your typical rotary...

    Use your band through the front hole down and around your Rca. So the band is farther from the armature bar

    sorry just saw video of your stroke. My cell phone couldnt display it. The longer stroke in the video is the normal stroke you want. the shorter faster stroke is caused from not enough tension or it can also happin at high voltage. The faster that weight spins with no tension on it, it will find a natural distance it can rotate back in forth. When tension is applied you dissrupt this natural zone and your capture alot of centrifugal force. Creating a beautiful hit and stroke. There is band setup that is real quick and puts your band right up to the tip of the tub for maximum support and tension. I will post that aswell as the others in the video i make tonight.

    still struggling to keep any consistency from the centri, when its running straight its cracking but then it goes out of sink, cant get any change at all from the stroke adjuster, and the armature seems to want to be in a more upright position when not on with means its starts to tap frame when running, and lastly what way do you guys have the inner plate, any pics would be good and vids of yours running close up of the stroke

    cheers all

    I had some issues like you are having. I had sprayed a bit of oil in mine. Later found out that was stopping the mechanism that allows the stroke adjuster to work. That same mechanism is what returns the armature to its neutral position. If your armature is in the up position when not running that internal piece may be worn down, broken, or slipping. Just my experience. I'm sure the guys at Centro can help ya troubleshoot. They are awesome.

    That inner plate that has the rubber wedge on it is what I'm talking about. It applies force to the motor assembly. That in turn keeps the pivoting action of the motor and armature within a certain range. It is what keeps the movement both up and down equal distances from its resting position. If it is not working right then the armature may be able to travel further in one direction (up or down) than the other. This inequality of movement is what throws of its rythem nd causes it to run inconsistently. At least that's what was causing mine to. Hope this helps.
