Default Re: Axis Pedal.... revealed

If your UDS is tight, it means slop is alive and well somewhere else in your Axis system. Having ruled out the key operated screws that connect the UDS to the axle rods, next step would be checking the 'Number Ones' on the pedals, the two mains and the Aux with the UDS unconnected.

Hold the pedals main post and try to move the number one(s). On the main pedal you can affect the beater for increased leverage on the shaft. If (any) side-to-side movement is detected, there's a good chance and highly probable the retaining washer is loose and not snug on the bearing. Snugging can be done with needle nose pliers slightly opened spanning the axle rod resting on washer.

Alternate pushing on the washer with pliers at 12:00 and 6:00 and 3:00 and 9:00 o'clock till its snug. You shouldn't be able to feel the washer causing friction when you rotate the shaft/bearings, it should move freely. If you make it to tight (feel friction) you can press the hex side of the axle rod against the floor with slight pressure until it frees up.


On another Axis thread I mentioned Axis' (or is it Axi) were sensitive to 'placement' in relation to squareness 'on the floor'. I called it 'proper grounding' and would like to touch on it again a little here. If the pedals aren't working smoothly between themselves, it can easily lead to the UDS and other soon to be mentioned places becoming loose or even damaged. This lack of squareness/flatness is more likely to originate on the aux-pedal and its relation to the main pedal via the UDS, though not limited to it. Always check both pedals and assure proper grounding.

When setting up your Axis double pedal (or any double) connect the drive shaft (Axis-UDS) to the main (bass drum mounted) pedal first. Make sure your UDS slides fully onto the 'axle rod' then secure it tight in the desired position. Next, connect the other end to the Aux (secondary) pedals axle rod. Lift secondary pedal in the air and set it down 'squarely/flatly' on the floor in relation to the main pedal, meaning when the secondary pedal is depressed, the main pedal is not pushed or pulled in any direction, there should be 'solid' interplay between the two with no movement.

If secondary pedal is not 'square' to the floor in relation to the main, the main pedal will be 'jacked' around from foot pressure and the workings of the UDS. This will cause multiple problems, not the least of which is going to be poor playability. Take the time to get the two 'grounded' and working smoothly together 'before' you begin to play.

OK, I mentioned 'there's a good chance' and 'highly probable' in the second paragraph as to where slop may be lurking and here's why. Side to side movement on the 'number-ones' can also be a 'misdiagnosed' as a loose retaining washer, since its somewhat hidden and not as obvious as set screws are. We'll... refer back to pic# 1 as to why another Axis mystery is virtually undetectable from the outside.

When you look at pic#1 what you're actually looking at is a 'defective' axle-rod (shaft). Remember, Axis pedals/parts are handmade. The threads which receive the hex end-nut of this axle-rod were cut too long. These threads should not extend outside the nut... and why? If you look at pic# 2 you'll see this is where the bearing sits. On this particular shaft (it came off a Aux Number-One), slop was detected but couldn't be pinpointed until the pedal was taken apart revealing the bearing sitting on thread's.

So, if your retaining washer is snug and everything else is tight, there's a (very) remote possibility this could be the problem. Remote because the pictured shaft shouldn't have made it on a pedal. Axis claims its the only one they know of and I believe them after talking with them while correcting the problem.

Start the negative comments barage? I can find screw-ups on just about any pedal run in production, things happen. I wouldn't go as far as knocking Axis for this one oversight, unless its proven to be more common than not, which I doubt..
