Only so much you can do with JB Weld.

There are all sorts of aluminum brazing rods around. Your local welding supply will probably have them in bundles of 5 (outside of a full box). Also check your local auto stores. Sometimes they carry Al brazing rods as well. Make sure you specify propane. There is one rod I see at stores that is about 1/4" square rod that melts and saturates cracks, as well as builds up and ends up stronger than the aluminum you're fixing. My dad has used the stuff on outer casings for dirt bikes and never had a failure, and since it isn't undercutting, you don't have a new possible break point at the edge of a weld. It's kind of like soldering, almost the same feel, but you have a torch that tries to blow puddles around (use to your advantage on larger areas).

Thanks for that info Dave! There may be life after JB Weld.

Take care

Forgot to mention... I was at Harbor Freight and saw they have some as well... probably enough rods to make an entire box, lol... but it was about $15.

thanks david, that is good advice.

my latest:


DBT stands for 'death by treble'

a trebly fuzz loosely based on the fy2 thread driving the modded wah.
only a bypass switch, fuzz and wah permanently married to one another, and no knobs either- what you hear is what it is.
( the FY2 is si q1/ge q2 npn with diodes to ground at end as well). lots of tweaks to make it feed the wah the way you hear it here:

That run you do at 1:09 coupled with the wah is freaking AWESOME! I totally dig Joe. 

[joegagan]

thank you ahren. i have a favorite moment, right around 3:26 to 3:30, seems right at the end i finally actually bonded with the pedal. vid was recorded within minutes of completing the pedal after 5 days of on and off tweaking and troubleshooting.

Here are a couple of odd wahs.
The first is a Tim Escobedo mix.  A Punch-In-The-Face fuzz driving a Gargletron filter.  Back about 4 years ago or so when I was building the Gargletron, jmusser was one of the only people who posted a build report.  I asked him how he liked it and he told me he wouldn't keep it if he didn't have the Punch-In-The-Face in front of it.  Since the PITF was so simple I put both in the shell.  There are DPDT bypass switches on the other side.  This way you can have wah, fuzz wah or fuzz.  Since the rocker controls the wah it has no effect when you only have fuzz on, but why not have the option for fuzz only, right?


This next one is a TychoBrahe Parapedal.  I was suprised to find a long-shaft dual 100k pot locally, but the Parapedal calls for a 10k dual pot.  While I was adding the resistors advised by Analog Alchemy, I found that by lifting one of them, I'd get a huge, amp rattling bass sweep.  The switch lifts that resistor.



Next wah on the list is the Freeper.  Built the circuit on perfboard, just need a shell and a hotpot.

[joegagan]

freeper? hey!

[joegagan]

the workshop. some of these look different now, this was a progress shot.

[John Lyons]

Damn that chevron patterned wah tread on the right looks ace!

[arawn]

yeah it does
i'm afraid i don't have the patience for it

[Güero]

I replaced all capacitors correcting some frequencies in this process and added a bass enhancer to lower frequencies.
It also has a 6 position switch to RANDE adjsutment, an ON / OFF Bass Enhancer and another key to open more the course of the Wah.

[joegagan]

guero, that is cool. i like the LEDs. did you modify the little tadpole shaped windows at the led/ldr mechanism? does the bass boost give it a different sweep?

[joegagan]

[Joe Stone]

wait, joegagan, are you using an aluminum forge for that, or did you cut it down with a dremel or something?  looks good.

[Güero]

A T-Rex Wah!  Very Cool!!

[Güero]

guero, that is cool. i like the LEDs. did you modify the little tadpole shaped windows at the led/ldr mechanism? does the bass boost give it a different sweep?

No, I don't modify that part, just electronic parts.
Capacitor changes, frequncy adjustment, etc.
The bass Boost don't affect the sweep, just brings up the low end.

[joegagan]

it is a standard dunlop top piece cut with grinder, saws on dremel, drill, flame tip on dremel, sanders, hand sanding, more dremel etc.

there will be a piece of lexan bonded up underneath to put back the structural rigidity and give some eery illumination to the cutouts.
