I learn from other's mistakes and hope they learn from mine.I expect I will learn less and less from your mistakes, yet more and more as you gain experience.
That's a good start, Jim! You should resize your photos to be about 800x600 so they aren't too big to download, or require scrolling on smaller screens.Simon
Hey, JimI'd better get moving on mine before you catch up.I usually find something that I forgot to do after I've finished a surface. I've made a set of aluminum soft jaws for my vise. As Bill said, clean the jaws. If the part is steel, the aluminum jaws aren't going to mark it. If it's aluminum, a piece of thin card stock (Manila file folder) seems to help. I saw someone on YouTube use copper sheet vise jaw covers for gripping brass and aluminum. Seems like a good idea.
Hi Jim, you aren't wasting any time making some progress on the #33. As to the vise issue, the most obvious thing is to make sure the jaws are clean and free of any chips which can press into the work when the vise is tightened, but you probably know that already . Aside from that, I don't find the vise marks any worse than the machine marks usually, but even so, I leave a few thousandths on the edges to carefully finish on a flat plate with 400 grit sandpaper after the machining is all done. This takes some elbow grease but eliminates both the machine marks as well as any vise marks.The same can be done with the lathe chuck, leaving just a bit of OD to clean up carefully with sandpaper or scotchbrite. if the jaws leave marks.

Sorry to hear of your accident!....Take time to let it heal, and keep the shop stuff out of it. Nasty infections from metal chips...Did the same thing with a lathe tool once...opened me up quite nicely....4 stitches on the digit....to say nothing of the beating I took from myself!.. Took 3 days for the Marcaine to wear off enough that I could actually feel my finger.....but no tendons or ligaments....thankfully!Dave
