I think it's always best to avoid grinding on the lathe unless there is a very good reason. The grinding dust is hard to clean up effectively and wears everything. If you have room for it, either a

My wife was using our 4x6 earlier this week to make some small angle brackets for a customer's project and cutting up some 3" x 6" tube for another one. I did have to modify my 4x6 bandsaw so a 3x6"

Yes, I cut off a few pieces that way before I got my bandsaw. Although you can get a decent cut with an angle grinder as long as you're careful, I greatly prefer using a bandsaw. I can get just as

Be sure to protect the lathe bed from grinder wheel grit & dust... Having a 4x6 bandsaw <http://www.harborfreight.com/horizontal-vertical-metal-cutting-bandsaw-93762.html> will really change how you

Intereszting video... How long did it take to cut the slot on the (delrin?) gear? What would the cost of making the lathe spindle lock, and the broaching tool holder cost? I guess if you consider

anyone else use one of those angle grinders with a cut off wheel on it to part off pieces inthe lathe? I set the lathe to go very slowly, and use that grinder's cut off wheel and it produces a really

That's a non-standard thread, you're probably not going to find it in a common drill size table. The easy way to figure the size is by subtracting 1/TPI from the nominal thread diameter. Drill Size =

Pete, Try Paul's "Drill Sizes pdf" in the Group's Files - it's around 2/3 way down the list of files, and tapping sizes are on the third or fourth page. Abdy

According to my "Machinery's Hdbk. 17 edition" for an external thread the major diameter is 0.4989 - 0.4924 and for an internal thread the dimensions are 0.461 - 0.470. John

That tends to be expensive tooling. Lowest cost, mount a cutter in the lathe toolpost, lock the spindle and wind the saddle backwards and forwards, or make an attachment for your lathe like this, see:

I'm planning to make a thread protector for a rifle barrel. My reference material doesn't list the drill bit size for a 1/2" x 28 TPI thread. Can anyone help? Pete

That was agonizing to watch!.... My god, bolt that thing to a bench!! broaching is easy, he makes it look dangerous. Just my 2c Paul

Those would be fine for taking a short nipple out of a fitting, but I don't think they would work well for *making* nipples. To do that, you'd need a longer item with a pipe-OD section to for the die

Cool stuff! Do you happen to have the english translation of the lang.txt file for hte gears program? Any instructions? I tried the newer beta (11-08-2012 and it didn't work but the 10-24-2012 version
