The Home Machinist!

Using what you have to work with... 7/8" Round bar Drill, tap, turn small diameter, and part off to rough length. Soft jaws on lathe chuck. Hold by small diameter, face to length and then cut taper. Soft jaws on mill vise properly surfaced and bored to accept small diameter of part. Run around perim...

Please post a better image, as you can tell absolutely nothing from that one!

No need to soften the socket to cut it.

Just part t off in the lathe.

I turned down the OD on a 2" socket on Monday for a friend. He was under the impression that it had to be annealed prior to doing so and was wide eyed when I just chucked it up and turned it.

I had virtually no rust issues in Miami, but here in Ocala, things rust for no reason.

Welcome to Florida!

I use both ends of the rod. Turn and bore one end to within .010" of finished size, then flip the rod and do the same on the other end. then go back to the first one. This lets the bronze cool off and relax a bit. Not as critical with leaded bronze, but aluminum bronze alloys move around quite a bit...

I knew them as Fimco Valves back when I was in High School, named after the manufacturer.

Every time the pump cycled off and back on it would change sprinkler stations.

It didn't take much to make them stick on one station...

My Camlock chucks all have an index mark on them that I put there so that they always get installed in the same position for repeatability, as there is a corresponding index mark on the spindle.

I saw in one of "Patio's" threads where someone asked about holding threaded objects. If you're too lazy to get out the soft jaws like I sometimes am, or don't have them, an aluminum sleeve to cover the threads works well for me. I make a fair amount of these, but only one at a time, so I have a ded...

AN stones have rack pins attached.

I was looking at the lapping section in my 1940s Audel's machinists manual and found a comment that taper laps were sometimes made, but they recommended against their use. They didn't say why, though. Tapered lapping isn't too good because the lap will wear with a pattern in it that matches the sur...

That's true!

Here's a quick google search. https://www.engineersedge.com/hardware/metric-external-thread-sizes1.htm The above chart shows "standard" ISO hardware class, which I would estimate to be the same as US Class 2. I use software for threading and you select the ISO number and letter designation for the d...
