  • Therming. A year in the making.

    Actually I guess it's been quite a bit over a year since I was asked to make this base. I kept putting it off because I knew it was a time consuming job. Just the setup alone took a couple of hours to ensure it was perfect. I did a couple more prototypes before turning the good one and found I had to make some changes to my jig. Then I finally mounted the Babinga. I have to admit, I was a bit nervous because I didn't have another Babinga blank and I didn't want to screw it up. Also, someone mentioned Babinga probably wasn't a good choice for this project.
    Anyway, I mounted it with chunks of maple for counter balance as before and turned the first side.

    I had to sharpen my tools a lot to ensure I didn't get any tear out. Once the first side was done, I was quite impressed with this wood. Hard, yes but it sure cut nice. The picture below is side one off the tool. I used a bowl gouge to rough the shape and cleaned it up with a honed scraper (no burr).

    I started sanding with 240 for this side. I sanded each side to 400 before removing the blank from the jig. The second side didn't cut quite as nice and I started with 120 and again progressed to 400. Once I was done I wet sanded the whole thing with 400. The pictures below are the finished base still wet from wet sanding (no finish)

    The hardest part of this is getting all three sides the same. When doing the last side, you have to measure often to ensure the three sides are all the same size.

    The only way to know when you have turned enough out is to stop the lathe and check the interface between the two profiles. When you have a straight line pointing toward the center, it's right.

    That means...take a cut, stop the lathe, check it, take a cut, stop the lathe, check it.........
    All together I think I have 10 hours just in this piece. That doesn't include all the prototypes I did. Maybe 15 in all.

    Anyhow, I'm very pleased with how it turned out and I'm glad it's finally finished. I'll bring it to the CNIB for anyone who's there to see it.
    All comments and critiques are welcome as always. And questions too of coarse.
    Thanx for looking.

    I almost forgot...The blank I started with was 6" X 6" X 2". The piece is only slightly smaller then that.

      Oohh that is nice JP, you pulled it off, that is sharp looking, maybe too good looking , I'd probably have only eyes for the wood and not see the sculpture
      You still have to sign the bottom JP, don't forget
      Thanks for posting the whole story and the final outcome, I enjoyed it all .

        That is amazing. Even after you showed how it was done I could not conceive ever figuring out how. The piece looks absolutely stunning and I'd love to have a closer look at it next Wednesday.

          Has it been a year since you started that.

          Yikes! I'm a year older!

          This was a base for something, if I remember correctly. Can you show us the base with the object it is intended for, or did I miss something in regards to this?

            You didn't miss anything. I'll get some more pics tomorrow. In the mean time, This thread has some pics of the statue on the prototypes. That thread started 12/08/07 but I was aked to do it around June of 07 I think..

            and here is the "how to" thread.

              Leo. I'll date it when it's good and dry but I don't think I'm going to sign it. It's for a stature that was handed down through the family and I don't feel right having my name on it. I know I made it and that's good enough for me.

                But J.P., think of the confusion you NOT signing it could cause some future archeoligist!!!

                  Base done by JP is what it could read, and that would add to the total IMO

                    I'm confused... is this made out of one single piece, turned in three setups? It looks that way from the grain, but...
                    Whatever it is, it's pretty cool, and must have been a bugger to figure out.

                      Wow!! You did a fantastic job J.P.

                      Clearly you paid the price for a great result. Any time you make that much effort and do so many experiments you deserve a perfect result.

                      Congratulations, looking forward to seeing it.

                        Well JP I was wondering when you were finally going to get your finger out and actually finish this off I mean it's not like you had anything else to do right?
                        Bloody excellent Yes you must sign it with the wood species and date.

                          Yes. It's one piece. The process is called "Therming" The center of the blank is mounted outside the lathe center and after each side is turned, the blank is rotated 120 degrees. It's not all that complicated to figure out but I did find accuracy is paramount for good results.
                          I like a good challenge now and then and as per usual, the first practice piece was very ruff and I found out then how much accuracy was need. After that, all the practice pieces were mostly to find a profile I liked.
                          If you're interested I posted a "how too" earlier.


                          I should point out. I didn't do 15 of these. The first bunch where round. I think I did 5 or 6 of this type before settling on this shape.

                          Here's a picture of the first one I did. This one was done with no planning. I just mounted the blank and started turning.

                          The side showing is the "good" side. The side you can't see is a real mess. When faced with something like this that I have never done before, I always try one first, fast and dirty, just to see what I'm in for. Once that's done it's easier to come up with a plan of attack.

                            Thanx guys. You'll both get a chance to handle it and I look forward to getting your "hands on" impressions.

                              One piece, okay. A similar thing is done to turn crankshafts and whatnot on a metal lathe. So you could, in theory, have as many sides on this thing as you wanted. You could have a 19-sided 'therm', though as you add sides you reduce the impact, or 'obviousness' that it's not a normal thing.
