split shaft pots (again, for use with push-on knobs) and when you tighten a set screw onto knob onto them, it pushes the shaft together creating a conical shape, rather than a cylindrical shape, and that causes an odd rotation as well.

I put something in the split, a small piece of wood, plastic or metal, to prevent the screw from pushing, bending and possible breaking one of the two pieces of the split shaft.

Are there pots with a d shaft?

Yes, they are almost as common as solid or split.

And as you said: it's a cosmetic issue and one that you only notice while turning the knobs, at least with the chicken head knobs.

On my Surfy Trem I have the same 'problem' but since I used round Fender (cup cake) knobs instead of chickenheads, at some positions it might look like I didn't drill the holes for the pots on a nice straight line.
I guess that's mostly your issue?

If it's indeed pots and knobs - heat shrink wrap tubes, works for me.
If it's inaccurate drilling, maybe some big washers.

SpankyPants, great enclosure idea! Keep posting.

For putting set screw knobs on split shaft pots, you can get brass sleeves made just for that purpose. They're pretty cheap. Here's an example:

So I got a set of these from this website, and it helped quite a bit. I wish I'd known about these from the beginning, because all my pot shafts are kind of bend out of shape and wobbly, but these really helped straighten them up as much as possible an reinforce the split shaft. I think they'll add durability to the pot. Thanks to everyone who offered suggestions on this issue.

My buddy Bill aka remora1 picked this kit up for me last year at the so cal convention, and I finally got it built and Incorporated into my board!

I'm considering a similar configuration for a future build. I am curious - do you get a spring pan crash when you step on any of the other pedals?

So I finally got to pick up my guitar a bit the other day and test things a little more. With the Surfy Bear on and switching any of the analog pedals will cause a VERY slight spring pop, except for the tube screamer mini, it is a much more noticeable pop. But really, still not that bad. No noise issues when switching the digital pedals. And no physical crash happening from regular use.
If I really want a crash I can pick up the board with my toe and drop it, that gets a good crash!

Very frustrated...several days building and double checking. All the wires shielded and properly connected. Power polarity correct. Ins and outs in the right jacks. All I get is HUM. Loud, obnoxious HUMMMMMMM....nothing but HUM. Tired...must drink more whiskey to diminish ever increasing desire to smash all to bits. When I was aboard my sailing vessel such things were simply thrown overboard into the infinite, endless depths of the sea. I know, I know...it must be me. Human error but I cannot see it.

Try another power supply. It's often the power adapter. If you have any battery with 12V, try this. If the humm is gone it's the power adapter.

I had some bad problems with hum when first putting it all together, and it ended up being loose connections with line in/out or reverb in/out - more things worth double checking to make sure the wiring is right.

Thanks...I will go back through it and check everything, again. I must have missed something.

Thanks...My power supply was giving me 15.4 volts instead of 12v so I added a dc to dc buck converter and knocked it down to 12 still got the hum. I'll keep looking...I have to be missing something.

If the power supply says 12V but you measure 15,4 volts with a digital multimeter that means it is an unregulated power supply.
That power supply was 'designed' for a specific device and should only be used with that device. That device will draw a certain amount of current which will make the supplied voltage drop to 12 volts.

Your multimeter does not draw enough current so it shows 15,4 volts.
Another device (Surfy Bear for example) might also not draw enough current and you'll supply too much volts or it might draw too much current and then you'll get less than 12 volts.

That converter is not going to help and might make it even worse.

Use a regulated power supply, one that always supplies 12 volts, regardless of the current drawn. Make sure it can withstand the current drawn by Surfy Bear, which is 1Ampere (probably less, but beter to be too high than too low)

So: buy/find a REGULATED 12V, 1A DC power supply.
