Fireplace Pan Electric Guitar

Fireplace Pan Electric Guitar

IMG_1430

I found this old brass fireplace pan at my local antique mall and immediately saw potential. The wrought iron handle seemed like it would accommodate two strings and it was long enough to provide a reasonable scale.

IMG_1431

I based the scale and fret spacing off of my son’s 19″ Zakk Wylde Peewee Les Paul, which was about as far as I could push the space provided. I used the rim of the pan as a bridge and, even then, I only had about an 1-1/2 of usable surface behind the nut.

As usual, space was tight; therefore, traditional tuners were not a viable option. Using the rim as a bridge, I installed the tuners down the side of the pan and my simple, linear machines were perfect for the space available. These tuners are cheap, efficient, and adaptable—many of my past projects would have been impossible without the flexibility offered by these machines. I placed the 1/4′ jack in the upper right instead of the lower right, because the protruding cord would be the least obstructive and it could double as a makeshift strap button.

The head isn’t spectacular, but I do like the functional aspect of the built-in wrought iron hanger. The nut is fabricated of a brass bolt cut to length and filed down to half its diameter. I left the head on, because the bass string pulls with greater force than its counterpart. The knurled nuts are my personal favorite; if I could, I would find a place for them in every project—they just look so cool and sometimes offer excellent function.

The pickup is my own Junk Shop Audio Nd144 style, great for 1-string to 3-string applications. It has a compact design and can be installed in a number of creative ways—in some cases it can even be hidden completely for a smooth, uncut top appearance, to better preserve original cigar box artwork.

The strap nut is created from a bolt, a beveled washer, a 1/4″ aluminum sleeve, and a couple of nuts. However, its more important function is to attach the metal strip that holds the pickup in place. The strap is made completely from red and black duct tape; I feel it complements the instrument well.

Quick and Dirty Acoustic Pickup

img_1274img_1324

I needed a pickup that I could easily install and remove from guitar to guitar—this is what I created with few spare parts I had laying around.

img_1269

I grabbed a Lego crate and lid got the housing and a RCA jack for the connection. The active agent is a piezo disk that I broke out of a buzzer housing.

Drilled a hole in the bottom of the crate and installed the RCA jack.

Then, I drilled a hole in the  lid and inserted the piezo wires.

Next, I soldered the wires to the hot and ground terminals on the RCA jack and closed the crate.

To allow for easy installation and removal, I added a 3/8″ removable Glue Dot to  the back of the piezo disk and one side of the Lego Crate. Done.

It needs some more sound shaping, but it has potential and is decent in a pinch.

Jumper Wire Test Box

Hi,

I originally created this test box in preparation for building a portable guitar rig. I had found an old RCA repairman’s vacuum tube box that, if modified, could hold a small tube amplifier, a 10″ Celestion, and a few effects pedals. I’ll likely present this “road rig” as an ongoing, realtime project later this year, but for now I will show you this excellent tool for figuring out complex wiring schemes. 
The box is simple in form; the only criteria I used in choosing the donor box was that it be flat as possible and have a length and width just larger than 8.5×11, so that a sheet of computer paper can be used for a template. To create the template, I used a drawing program from an old software cluster called Apple Works, but you can likely use just about anything.
 IMG_2115 IMG_2119
I tried to make my box as versatile as possible and therefore included two rows of six 1/4″ jacks, one row of switches and one row of RCA jacks (which require the same sized hole and are interchangeable), one row on the bottom for speaker jacks and speciality items, and one row above with pilot holes drilled for expansion. You need not fill all of the holes with components, as it can get quite expensive; it’s better to get a few items to play around with initially, leaving space for project specific components.   
IMG_2116
The pictures are self-explanatory, but the easiest way that I have found to make a box like this is to print the template, tape it to the box as straight as possible using painter’s tape, drill pilot holes with a small bit, remove the template, and then drill the various sized holes for each component. If you like my template (shown below), follow the link to my Google Drive account and download the “jumper wire test box template” file: https://drive.google.com/file/d/0Bz_BJp6_LjKySVVjQTRvVXBZVzA/view?usp=sharing

The strips of painter’s tape between the components allow you to label each component when wiring for easy removal and reuse; and the jumper wires make experimental wiring a breeze. Simply wire, plug up, test, and rewire if necessary. When you are happy, set up your permanent project box and wire it based upon your tested design.

Homemade Promotional Guitar Pick Project

Homemade Guitar Picks

Hi,

Over the past few months, I’ve been
trying to get the word out about this site and recently entertained the idea of making homemade, promotional guitar picks to distribute. I believe I have stumbled upon a reasonable process and wanted to share it with you.

The process entails printing 56 pick-sized designs on a sheet of transparency film and then laminating it. After that, four laminating pouches are cut into eight separate sheets and are then laminated to the back of the primary sheet one at a time. Finally, the picks are harvested with a Pick Punch and finished with 600 grit sandpaper.

This project takes a little effort, but the final product is a very excellent, medium-gauge pick. Detailed instructions are in the works—in the meantime, have a look at the attached images.

Thanks,

December Project — 9 Volt Power Adapter Guitar Pickup

Hi,

December’s project is a high output/low noise guitar pickup, constructed of two power adapter coils, four metal picture hangers, a handful of neodymium magnets, and some electrical tape. This project comes in under $20 and can be modified to fit a number of applications— whether it’s a replacement pickup for a stock guitar or a home build like the six-string steel guitar I’m working on or even a four-string cigar box guitar.

I’m excited to release this versatile pickup design and am extremely happy with the results thus far. It’s stereo capabilities and compact design offer numerous options and I am convinced that further exploration will reveal many more useful applications.
