  • 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.

What is the angle of the pins that hold the compound rest on the swivel and can they be made of brass. the angle looks to be around 30 degrees

I made a spare set out of brass, and for the angle I cut a piece of cardboard to fit the compound undercut and used that as a template.

On my Atlas 618 they are .202 - .203 in diam. and have a 27.5 degree nose angle. They are made of steel for a reason, brass is for decoration.
Also it is important to round over the long end of the angle.

I was just about to write the same thing. Brass is too soft. You didn't say which lathe you have. The compound swivel lock pins for the 6" are M6-309. For the later 10" and all 12" they are 10-309. In Downloads is a drawing of the 10-309 that I made from one of mine about six years ago. I haven't checked recently but last time that I did, they were still available from Clausing, so they won't release the Atlas drawings.

Note that on mine, I measured the angle of the bevel as 60 degrees (or 30 degrees for the included angle. And the diameter is 0.310". Note also on the sketch the radius cut on the bottom of the bevel.

I have a 10 and was going to do some milling with the attachment and the pins would not slide back to remove the compound so I drilled the pin and used a screw to remove them, I made a couple out of brass for now and cut them at 30 degrees until I make a couple out of steel. How do I access downloads?

BTW, if you drive a groove pin into the hole in the compound swivel locking pins, and then grind it off flush, you can still use the originals once you have confirmed that they will now slide freely all of the way through the holes in the Swivel.
