    Any guesses?

    Turned these tonight, and cut the steel stock yesterday. I'm sure its apparent what these will end up becoming. There's one more in the works to complete a set of 4.

    I decided to take a shot at making these based on some Youtube tutorials. The wood is some poplar I bought on the cheap (from 8/4 stock 10in wide, I got a 10 ft piece for $5 because it was twisted) - it is stained with Minwax "Provincial". The steel rod is from the BORG, 3/8in square x 3ft length for ~$7. When done, the handles will be ~13 inches, and the rod will extend another ~6 inches; so I'll likely have $40 total invested for what retails for ~$400 from Rockler, Woodcraft, etc.

    Thanks for looking.

    looks like you'll have a nice set of turning chisels.

      Too easy! Looks like the handles turned out great! Are you going to harden the steel or is what you bought hard enough to hold an edge?

        It looks like they're set to mount carbide cutters.

          Right. The best kind of lathe tools. Custom made by you.

          If you have a torch (Map gas better than propane) you can anneal the ends. This makes it easy to shape the tool ends. I always wrap a wet cloth around where I don't want annealed and keep it wet.

          Grind your basic profile. Then harden and do the sharpening. My FIL used to make knives and that was his process. They would hold an edge pretty well.

          To anneal, I heat the end red hot. Then let it cool at air temp with that wet rag still in place. Then you can work it easily.

          Heat it red hot again afterward and dip in oil. Do that a couple times and you will have steel that will keep an edge awhile.

          Different processes of course for different grades of steel and what you actually want to achieve, but it isn't that hard to do.

            Yes, good guesses about these becoming lathe chisels. And Jdon is right about the carbide - I still have to drill and tap for the carbide inserts. So I won't actually be trying to shape the steel itself.

                what is the wall thickness of the 3/8" square tubing? Do the carbides fasten with set screws?

                  Gerti I may get the carbide from Capn Eddie but I'm still shopping around and appreciate any input on a good source.

                    3 of 5 Complete

                    I finally had some time to assemble 3 of the lathe tools. I finished the handles with spray shellac, and used epoxy to anchor the steel shafts and copper ferrules. I'll have five tools total when done; I have two more in work (need to finish handles). These were planned around a square cutter, a 4in radiused square cutter, a round cutter, and two diamond cutters. I may add a sixth tool if I get a round sheer-finishing cutter.

                    For the carbide, I went with AZCarbide in Chandler, Arizona. Dale Guilford is the proprietor, and provides a personal touch by contacting his customers directly to confirm their purchase. I found his prices extremely reasonable (much lower than my local woodworking supply stores), and he uses very affordable flat rate shipping ($2) with delivery tracking. The cutters arrived yesterday (see photo showing packaging) - and they appear to be very high quality. Dale provides the mounting screws as well (#8-32, but I damaged my 8-32 tap, so those shown on the mounted cutters are some #10-24 I went with instead). Here's the website: http://azcarbide.com/. Dale also has an eBay store.

                    All told, I have about $50 invested in creating these 5 tools. And I still have materials left over to make the sixth, so that tool will be a "freebie" less the cost of the cutter. So $10 a piece. Each tool is 18inches total length - 12 inch handle, and 6 inches from ferrule to cutter.

                    I received the cutters yesterday, and mounted them to my tools today. I hope to give them a try tomorrow to produce those last two handles I need, and will post my impression of the cutters.

                    Thanks for looking.

                      The tools look great! You will enjoy using something you built a lot better than store bought. 4:20 am, doesn't anyone sleep around here?.

                        Nice work !

                        Interesting philosophical question arises --- how were the first ever turning chisels made?

                          Those look great. Yes, please report back on how they work out.

                          The carbide cutters I've seen sit in a recess cut out of the bar stock--maybe so the cutter can't spin around? I can't tell from the pics if you did that or not.

                            Paul, they're working great. I just completed my last bowl entirely with these tools, loved how they performed. Another shout out for AZCarbide - the cutters are great!

                            And yes - I ground in a slight recess on the steel bars for the square and round cutters, but not the detailers, since I don't have a milling machine to cut that geometry. As it turns out, a recess isn't really necessary, as the screw used to anchor the carbide cutter provides sufficient friction between the cutter and steel so they don't rotate during use (in my experience). However, I was prepared to use the Capn Eddie method if needed - he puts a drop of CA glue between the cutter and steel if needed, which can be heated later to release the cutter for rotation/replacement.

                              Oh man, those look great. After I build my stand I might have to research this further.
