  2. I'm pleased to announce that Tom Lohman, the master of high-density Painted Segment bowls has created Volume 1 of designs for Segment PRO. His volume includes 30 designs for 48, 60 and 72-segment designs - all for the low price of $15. To see sample pictures or to purchase the volume, please visit his website at segmentedturning.org.

    I'm back from wood shopping. Just need to rip out my material form two more species of wood, then I can run them thru the planner and start my new bowl. With the new jig I'm only going to bump up to a 60 segment per row bowl for starters. I'm going to use of Tom Lohman's designs but am putting it on a different bowl profile. It has a total of 2040 segments

    Hi Bob, looking forward to seeing your new design and your new jig in action. I did a little bit of tweaking to my jig this morning and was able to get under way with cutting my first round of segments, BOY THEY ARE SMALL. I also glued up the waste block and the first solid disk. I'm thinking I'm going to change out the angle aluminum as well and add a much thinner piece.

    Did get row 1 back on today. Had a little miscalculation on the first attempt and had to turn it back off. It gave me a bit of practice flattening the disc then shaping it a bit. That unfortunately did not go so good as the thin ends basically tore off. This scares me a bit for the next time. I will wait until I have three or four rows on before I try turning the inside shape.

    IF ANYONE HAS SUGGESTIONS ON TURNING THESE DELICATE LITTLE PIECES PLEASE LET ME KNOW.

    I did use a stainless steel ruler in place of the angle aluminum. It is much thinner and even allowed me to place the last segment. It also provides the measure for the outside dimension.

    They are small my first row the SEL is 0.17".

    Do like Tom Lohman, use a power sander to start with

    I saw a vid years ago from a woodturner who turns very small stacked laminated pieces (1/16th - 1/8) that was separated by small wood bars. He placed the glued up blank into a coffee can and poured in heated/melted paraffin wax. The wax filled in all the small spaces and provided support to the very thin wood. Basically the flimsy blank became a solid blank. Once cooled he would mount the piece on the lathe and turn his design. Once done, he would use a heat gun to melt the wax from the fragile shaped turning.



    I know this is not much of a description of the process and I am not sure how well it would be used in your bowl project. I could see building up the segmented piece to a logical stopping point, doing the wax thing and turn to shape. Then cleaning up the top, adding layers, and repeating. Just a thought on how to support very thin pieces for turning.

    I will admit I have not done this process yet.

    Very interesting it must work ok only drawback I can see is you would have to have a wax finish. Can't see any way to remove wax for other types of finish.

    Interesting concept Mike. He has some unique turnings.

    The method does limit the finish you can put on a turning, but it is one way to stabilize very thin pieces.

    Haven't tried it, but what about putting ca glue on them to harden them, the way you filled cracks or punky wood. Just a thought

    Thanks everyone who responded in regards to turning these delicate segments. I did re-make the first row and again after flattening I managed to damage the outside overhang. I used this as an opportunity again to try power sanding the centre to establish the profile. This did take a bit of time and was mostly successful in cutting the profile. What I didn't like was the finished profile in that it didn't have a nice crisp line to it and there were also a few segments that had chipped back a bit from the taper edge.

    I have a few family issues going on in the next few weeks so I will probably not get back to it for a while. I will have to contemplate my next move. I may go back to 60 segments or I may try doing it as a closed segment project.

    Like I had said before I have a new sense of respect for those that do these high density projects. I cannot imagine doing 144 pieces but there are folks that do it very successfully.

    I took your advice an ordered a Total Saw Solutions blade. I am very impressed. It takes almost no effort to cut through very hard wood and the cut is very smooth. For segments it works extremely well in that you don't send any more expensive dust into the vacuum than you have to. The people there are very helpful and it is an American Company with products made in America. Go to their website and view their blade in action. The blades are not cheap but they work far better than the normal blades we use. I was using a $130 Forrest woodworker II blade which was O.K. but was not as good as this blade. I consider this a significant upgrade. It will make any saw perform much better. Also to any Shopsmith owners I put a review in their Forum on the blade. You will need to make some adjustments to the lower saw guard because of the blade balancers.
