  • As some of you know, I have wanted to stop managing H-M for some time. It's a tremendous strain on my personal life. I want to set up my own shop. In September, September 15, to be exact, it will be 8 years that Hobby-Machinist has been in existence.

    We've seen a lot of changes. In March, 4 moderators left to start their own site. They took some of you with them. So now you have split loyalties. You know who you are. They didn't like my way of managing this place, and thought they could do better without me. They didn't. The only thing holding them together is that they hate me. Their site was down until mid July. That is why I wanted to stay involved on here until they could learn to run this place. But they wanted me to leave right away, without the training part.

    Anyway, I have been training VTCNC to run things here. Dabbler is going to learn too. I feel that they are ready to start taking over the operation. I will be here to help in case they need, but I don't think they will. Tony Wells is and will be here also to consult with. I will be doing backups, upgrades, and installing addons. Other than that, I don't want to know about this place.

    What about the 4 moderators who were disloyal? I don't care. It isn't my call anymore. I would think that, rather than fumble, they ought to come back and do good work. That's up to them. If they want to return to try to lead more members to their site, I am done caring. I suffered too much aggravation worrying about it. I don't plan to spend any more. What they do impacts on them. I have my own opinions including those of you who followed them there. No longer my problem.

    I am leaving this place in good operating condition, and financial condition.

read something about getting a ultra fine finish (in the absence of a ground finish) using a file and "paper". what am i missing about the "paper" ?? or, in my golden years did i missread something. in my older years, instead of claiming stupidity; i like to state that i am a old man, its to be expected

Yep I remember watching my father polishing ejector pins with wet & dry until they fit the bore in the die, no CNC in those days.

He always used a file to chamfer edges, never saw him use a chamfer tool.

There is a trick with "real paper".... I've used newspaper and WD 40 to put a fine cross hatch on polished barrels.

Heard the paper thing, too. Brown paper grocery bags are just abrasive enough (used dry) to polish a fine finish. I doubted it when I heard about it so I tried it on a finely turned piece of stainless steel and it worked.

One my dad would do is first polish with the fine wet dry emery paper, Then turn the paper over and use the back side of it to finely polish pieces.
