Here's a project I completed some time ago. It's a scissor knurler, made from bits and pieces again. I bought the two knurling wheels on ebay and made the rest myself. No mill, so made it using the lathe, linisher and files. The most difficult part was cutting the slot in the middle section of the upper and lower arms for the adjuster screw, as you can see it's a little wonky. Been using it for quite a while now, does a pretty good job - very handy!
