Step bit or twist bit to drill your aluminum?

I’m pretty interested in learning more about working with Aluminum specifically for enclosures, etc, but realistically, I’ll just be using more basic, powered woodworking tools and hand tools. I’ve been doing some searching online as well, does anybody have a really good link or source for good basics or entry level type tutorials? 😇🤔

Step bits are typically better suited to drilling thinner aluminum sheets, it also deburs the aluminum too. Drilling thicker aluminum stock is better suited using a twist bit. Regardless of bits used, a center punch is recommended for accuracy. Cutting lubricant increases the lifespan of your drill bits. If your drilling aluminum stock thicker than 1/2", a drill press will benefit you substancially, keeping the hole drilled accurately to your specifications.

Made all the changes today, case looks fantastic...... but it doesn't fire. Not sure if I toasted a part on the board or if the little tiny button on the front of the board actually does something as a safety measure. ¯\_(ツ)_/¯   There is power to the board, the main cap has 58v across it, but can't verify power after that and no lights or any sound. I didn't pull off the volume pot just yet, as I figured baby steps in mods. Either way, I'll do some troubleshooting to find out and worst case scenario I start over after buying another for $80.

But it looks great in there. And yes I know I accidentally drilled the board a little crooked. 





P.S. if anyone is planning to desolder anything on this board, you'll want a minimum 60w 750° iron as their lead free solder sucks to melt. I went and bought a big fat Weller 900° gun just because of this.

That looks so freaking cool!!😎 👍🤟

Lloyd,
If you need attenuator / switch extenders, here is one example available. I've personally never used them, therefore do your research to make sure they're a legitimate bussiness. https://www.audiyo.com/ext-kit.html

Using extenders, will give you more flexibility locating the PC board. If you relocate the PC board closer the rear of the enclosure, near the tube connectors and RCA terminals, your less likely to experience noise in the signal path. Simply by having shorter wire runs, will be beneficial. Longer wires have more surface area to act as an antenna, picking up electromagnetic interference (EMI) from sources like household wiring, radio signals, or for that matter any other audio associated equipment you have nearby.

Yeah my end goal is to remove the volume attenuator from the circuit rather than using an extender. If I need to keep it in there, I'll just keep it tucked inside the case with the volume up to max. I probably could scooch it back a little to limit cable lengths but wasn't super worried at the moment. Always a good tip though.

Just in case I did something legit bad, I have another on the way from Amazon. Joys of inexpensive items, trial and error is not a concern. Hoping to tear into the other one tomorrow night to figure what I did though.

It's alive! Sometimes you do a big oopsie somewhere and just need to start with a new board. Snagged a new one, mods all redone as well, and just left the DC input and wired a plug. I'll let it play for a while, before assessing difference, but right now it sounds great and looks even better. 

P.S. I still say doing these mods necessitates dual soldering irons. Also the little tiny button tab near the high pass knob is actually a ground connection. That's now hard wired to a star ground in the middle (purple wire).
