  • Reverse boring

    Built a drain pipe for the kitchen sink on my lathe, but forgot to turn down one end of the pipe to 40mm. But a tip that I found in "Machine Shop Trade Secrets" by James A. Harvey saved me from having to do the part all over again This book is excellent, worth its price just for this tip alone...

    Basically, I put the pipe into the vise, aligned it to the spindle axis and then used my boring head with quill auto feed to shave off from the outer perimeter. I was pleasantly surprised by the very nice surface finish, didn't expect that.

      Had that "discussion" with the wife long time ago. It wasn't pleasant, to say the least

        I think I see your problem -
        Your machines look too new and shiny. That always looks costly to the uninformed. You need to start getting some old beat up looking stuff in there that looks like you were paid to take it...
        Nice solution for the problem though. I'll have to try that out one day.

              Awsome idea! then when she asks how much it costs, you show her the real bill, but have the seller put a little - infront of all the prices. (And maybe add a decimal place if you paid a lot, so it looks saner. Ie $2000 becomes -$20.00

                  How many of those carbide inserts did you wear out on that job?

                  Do yourself a favor and see if your TV carrier has America One News Network (AONN). 208 on Uverse. It is good old fashion news, unlike the networks, with no hype, bias or other BS.

                    Another thing that I have used a boring head for is cutting O-ring grooves.

                    Boring heads can do more than bore holes.

                      A good tip and sometimes it's the only way if the workpiece won't fit on the lathe, but don't forget...a threaded shank can unscrew itself from the boring head if it catches or if the load is high enough to break it loose on the threads if you are using a right hand tool. Just saying as a reminder...

                        And here I thought this was about putting material back on, not taking it off.

                          You should clean your shop..totally unsafe and disgusting.

                          Seriously tho, a very nice machine in the picture, and the rest of the shop looks nice as well.

                              It's a 175x300mm vise. Here is the picture from the vendor's page:
