Hofner Colorama II restoration project part 4 stripping and scraping the paint off the body

In the continuing sage of our vintage Hofner Colorama II restoration project, today we will be stripping and scraping the paint off the guitar body itself. If you’re already following the project, you’ll be well aware that we’ve already removed the neck. This is what we’re left with: Stripping a vintage Hofner Colorama (by which I mean stripping it of its components, not the paint, though we’ll be doing that too) is extremely easy. First we take out all the scratchplate/pickguard screws, allowing us to lift the whole thing out, including the output jack, in one go. Next we remove the front vibrato/tremolo cover as follows (you should unscrew the tremolo arm before doing this – in this particular project, removing the arm was a bit of an adventure in itself and will be documented later, but usually you simply unscrew the little thumbwheel and the arm comes off easily): Now the back vibrato cover: The vibrato itself is secured with four screws in its corners, so we remove these too. Once...

Touch Switch II Circuit Diagram

This circuit uses a 555 timer as the bases of the touch switch. You can learn more about 555 timers in the Learning section on my site. When the plate is touched the 555 timer is triggered and the output on pin 3 goes high turning on the LED and the buzzer for a certain period of time. The time that the LED and the buzzer is on is based on the values of the capacitor and resistor connected to pin 6 & 7. The 10M resistor on pin 2 causes the the circuit to be very sensitive to the touch.

Hofner Colorama II restoration project part 5 filling and sanding the guitar body

In the last post (http://diystrat.blogspot.com/2011/11/hofner-colorama-ii-restoration-project.html), we stripped down and scraped the paint off the body of our vintage Hofner Colorama II guitar. Before we even consider repainting it, there are quite a few issues that need our attention. These are mentioned in the previous post, so if you haven’t already read it, please feel free to do so now. First of all, one of the screws holding the front tremolo/vibrato cover on was not gripping very well. This turned to be a result of the screw hole being too close to an edge, causing the hole to fall through that edge and making it impossible for the screw to get any sort of grip. We can’t just fill this hole, but rather, need to rebuild the surrounding wood so that it doesn’t happen again. Additionally, the lack of wooden support is the most likely explanation for the split in the tremolo cover, which was discussed here: http://diystrat.blogspot.com/2011/09/hofner-colorama-ii-restoration-project...
