For an easy way to improve the appearance of machined surfaces, consider bead blasting. It has little impact on the dimensions of the surfaces, but large blasting cabinets consume lots of air. If you have a small compressor (5CFM or so) blasting is still possible using a bench top cabinet with some improvements. I would like to share a video the improvements that I made. I really enjoy abrasive blasting both for clearing crude off old parts and for creating a matte finish on nearly machined parts.

If you have suggestions please let me know. Best wishes, Kent
