When filing in a lathe, don't hold the file rigid, but use a slight gliding motion. This will help the file clear itself and also prevent ridges. When filing metal, vary the speed according to metal. Generally use 150 surface feet per minute for cast iron; 175 for annealed tool steel; 350 for machinery steel, and 500 for soft yellow brass. Also, don't run your hand over the work. Resulting oil and moisture will make it harder for the file to take hold.
Worn-out nylons can be used to hold tools on pegboard if you run out of pegboard hooks or have something bulky to hang up. Knot up one end, then feed the nylon through the back, and then loop it through appropriate holes for the tools you want to hang. The nylons will stretch nicely to fit various tool shapes and will actually hold the larger tools more securely than the older-style pegboard hooks. This trick works best if you are able to gain access to the back of the pegboard.
