Custom Sharpening Fixture
Customer had made a homebuilt bit sharpener jig using off the shelf abrasive disks and a Pearl rotary machine. Customer was using velcro to affix disks to the plastic plate that came with the machine, but could not get a good center. Made this arbor to true the plates and mount them to their rotary machine.
Left-Handed Wheel Fixture
Surprising how often the left hand side of polishing wheels are left unused due to losing the left handed nut. Here properly left handed nut/spacers made to put the other spindle back into service.
Sputter Target Holder
Customer bought a tabletop sputter system second hand. Previous owner had been indium soldering targets to the stud each time. Reviewed images of their machine and created this sputter target holder. Center bore threaded to mate with the machines 1/4x20 mount. Pocket in place to accept sputter magnets. Outer ring threads on to hold the sputter target in the gap via compression.
Milled Sword Fullers
Customer hand ground a 1/4in. springsteel blank into a heavy sword, but the weight made it a little too heavy. The Shoestring Machine Shop milled the fullers seen in the image to significantly reduce weight without sacrificing much integrity of the blade.

Notes:
Shoestring Machine Shop is a small garage scale business. Tight tolerances may be difficult to hit (but we'll try!). Complex geometries like curves or helixes are better serviced by full cnc machine shops. We focus on those smaller scale one off jobs that just don't make sense for the larger shops to spend the cnc tool time and setup on. Sometimes you just need a slot cut or a bushing made and are on a tight... perhaps shoestring... budget. That is what this shop is for!
