Andreas Preuss Posted October 1, 2020 Report Share Posted October 1, 2020 (edited) I was just cleaning my shop putting back tools in places where they are supposed to be and realized that quite a few are self made and still in useful service. Enjoy! If there are any questions, feel free to ask. Would be my delight if other MN could post their self made useful tools.

Andreas Preuss Posted October 2, 2020 Author Report Share Posted October 2, 2020 (edited) @Brad Dorsey this looks interesting. Or let's say I couldn't figure out its purpose. Edited October 2, 2020 by Andreas Preuss Add text Quote Link to post Share on other sites

Andreas Preuss Posted October 2, 2020 Author Report Share Posted October 2, 2020 @TJ Fuss Though you named all your tools, I couldn't figure this one. Does the acrylic glass part belong to the clamping(?) device above? (I wished I had a brother making me tools) Quote Link to post Share on other sites
Andreas Preuss Posted October 2, 2020 Author Report Share Posted October 2, 2020 Yesterday I didn't have time to write explanations for some of the tools: 1 this is a device to measure the distance BETWEEN strings at the bridge. (The line to mark the distance is scratched on the plastic and not visible on the picture) is sThe cutout is to measure the string crossing angles. Quote Link to post Share on other sites
Andreas Preuss Posted October 2, 2020 Author Report Share Posted October 2, 2020 Next A small self made saw to cut the insertion for the lungs into the corner blocks in Cremonese style. Maybe not absolutely necessary but I found it easier working with this saw than with a chisel. The blade has of course just the width of the linings minus alpha. (This was the reason I made it myself because saws with such a wide blade are not sold anywhere.) Quote Link to post Share on other sites

Does the acrylic glass part belong to the clamping(?) device above? (I wished I had a brother making me tools) It's a crack clamp - more typically used on guitars to cleat a crack when you're not going to open up the box. Tie a thin wire or monofilament to the clear part and thread it through a cleat and then through a very small hole in the top to the mounted guitar tuner on the ourside. Turning the tuner tightens the wire, locates and holds the cleat in position while the glue dries. My brother made the four sided sharpening paddle and the bench hook. I made him a panel gage (that turned out better than mine). We've been doing handmade Christmas gifts for many years... we still haven't run out of ideas! Quote Link to post Share on other sites

Andreas Preuss Posted October 2, 2020 Author Report Share Posted October 2, 2020 Here are 4 tools. The wooden panel is my device to hold violin and viola bridges. The blanks are stuck on the aluminum fixture at the cut in of the ears. (Don't know if this explanation can be understood) the acrylic glass template is the transparent fingerboard for drawing the fingerboard position on a neck graft to center it to the head. the small metal plate on the right with orange paper on it is my 'bend a sandpaper' for some jobs where I need a small sanoaper file have a certain shape (and eventually adjust it while using) the last is a self made arching channel gouge. It's made from an old file and is one in a set of 7 I have made so far. Quote Link to post Share on other sites
Andreas Preuss Posted October 2, 2020 Author Report Share Posted October 2, 2020 Next is one of the more sophisticated tools I made already years ago. It's a self made precision purfling cutter. It is used when top and back are assembled on the ribs. Usually a purfling cutter has only one leg as a guiding device. I made two to stabilize the cutting direction and additionally extended it long enough to reach the other plate si that it can't tilt during the cutting. The screw from the top (visible on the right cutter) serves to regulate cutting depth. The only disadvantage of this cutter is that it does not keep the same distance from the edge on the arrow curves at the corners. Somehow I abandoned this tool because the purfling was looking too clean. (In between the cutters is a sandpaper file to make strad type f hole points because I didn't want to buy the tool which is available from some suppliers) Quote Link to post Share on other sites

Andreas Preuss Posted October 2, 2020 Author Report Share Posted October 2, 2020 Two more simple devices A sandpaper file to finish a bass bar and a knife to cut the purfling channel holding the handle vertically. The later one is my first self designed tool which I made when still at Tokyo Violin Making School. Quote Link to post Share on other sites

I too have made quite a few tools and jigs when I first started but now 15 years later I hardly use them and even forget what its purpose was sometimes. Here is a example of a tool to clean out the purfling corners... that I do not use now. It was made from a fine tooth hack saw blade and has curved ends. But I do use my homemade pasta maker to squeeze the purfling from 1.2 mm to 1.0 mm which makes inserting the purfling quite easy. It has a taper so the the final thickness is controllable by using a wooden block spacer Quote Link to post Share on other sites
Jim Bress Posted October 2, 2020 Report Share Posted October 2, 2020 This is my most used jig. A basic shooting board. Quote Link to post Share on other sites
Mat Roop Posted October 4, 2020 Report Share Posted October 4, 2020 3 of my favorites... which I also sell The first two are great time savers, and the third is soooo safe to undo stuck pegs. Quote Link to post Share on other sites
Andreas Preuss Posted October 4, 2020 Author Report Share Posted October 4, 2020 @Mat Roop beautiful! The third is to undo stuck pegs? looks like glue to me. Quote Link to post Share on other sites

From Mat's website, moisture absorbing silica beads. Pretty neat idea. I can't figure out why ice cubes are needed when microwaving to remove moisture from the beads.

The problem I had was that the usual cobalt blue indicator beads are toxic if you try to dry them out either in a regular oven or microwave. This orange one turns to deep green when saturated, and contains no toxic materials so drying it out for reuse is safe. The reason to put Ice cubes in the microwave is simply out of an abundance of caution, as I would not want anyone to burn out their microwave oven if they leave it on too long ... but, without ice cubes, the moisture boils out real quick.

That makes more sense. When I worked in a lab we recharged these desiccant beads in the microwave by themselves. Of course we didn’t care if the crappy microwave broke. I’m sure your customers would not agree. Quote Link to post Share on other sites

Now I get it. Actually I got confused by the amber color. In Japan those silica beads are used in many food packs, mostly for foods which have to stay crispy in the packing, but as a matter of fact they are always white.
