- 5) Wind the crosslide back in to zero and continue feeding the tool in using the compound. When the compound gets to zero you are at depth. One simple calculation for depth and you don't have to remember your last reading on the dial. Unified Depth of thread. External =.61343/TPI Internal =.54127/TPI (Minimum).
Internal Threading Lathe
Update skype for mac. See full list on openoregon.pressbooks.pub. Threads are size according to their outside diameter and the number of turns per inch. 0.75' x 10 t.p.i. (0.75' in diameter and ten threads per inch). Or, for metric threads, on their outside diameter and the distance between the crests of the thread e.g. M10 x 1.5 would be a 10 mm diameter thread with a distance between the crests of 1.5 mm. Use a good quality thread to prevent excess lint in the machine. If your stitching is uneven, that means the tension needs an adjustment. Change the sewing machine needle regularly. Start with simple projects and focus on learning and mastering your machine's speed and settings.

Metal Lathe Threading
The 1/2 Hp motor is strong and once I converted the belt access door to thumbscrews changing speeds is not a real issue. The two BIG drawbacks are the fact that the tailstock backs off (no matter how tight you have it) and the toolrest is really inconvenient to adjust in and out as it uses a bolt with a nut below the bed. The LITTLE drawback is that the headstock does not have an MT2 taper (or MT1 for that matter) so everything has to screw on to the external threads.
I've been using it for a horizontal sander but now have one of those. I have two thoughts.
1. Shorten the bed and use it to rough turn bowls (I have a 4' plate and a talon chuck adapter. I can bring the live center on the tailstock all the way back to lock and use pressure to secure it. Shortening the bed would give me back some counter space as I'm not likely to turn 40' deep bowls.
2. Turn it into a permanent buffing and polishing station. The rub there is the lack of an MT2 so I would have to have a mandrel custom made. I talked to the machinist at work about grinding off the end of spur center and welding it to threaded rod to put washers and nuts on for holding the three wheels. He started to say it was a dumb idea then thought about it and changed to 'dangerously stupid idea'. At least he doesn't soft soap me! His issue was with the softness of threaded rod.
I am eager to hear what any of you have to say about either idea. Maybe you have one I haven't thought of.
I hate to throw it away and feel it would be dishonest to sell it to someone unaware of the problems. If you're in the local area you can come and get it for $30.00 cash or check (no PayPal)[}] and come up with your own ideas.
