Inspired by #MobileVise and the scrapvice in #Misc. spur-of-the-moment projects, I decided to make a simple version of the wonderful #Stickvise - low profile soldering vise by @Alex Rich.

Parts:

One 4x70mm machine screw with nut, One small spring from a printer (any spring that fits around the screw) and a scrap piece of wood.

I drilled a 4.2mm hole through both pieces of wood at the same time to keep things aligned. I used a saw to make a groove just above the hole on both sides to give the PCB somewhere to click in. The picture pretty much says it all.

This is a pretty useful kind of vice. You can play with different ideas (eg having two threaded rods or screws, one at either end, to clamp something in the middle with a bit more force). Or you could make a more conventional C clamp with a few extra pieces of wood. The spring means you can easily clip something in and out, but you can remove it if you want more brute force clamping power.
