    A Twisted Form

    Thanks for the suggestions. I ran this past some club members at the meeting last night and got some other valuable ideas, as well. The degree of curvature is more than I thought, like 1/4". I did try the sand paper on the cast iron top idea, but that's going to take quite a while. By the way I suggest covering the top with craft paper otherwise the cast iron will be scratched by loose grit. And yes, there's a reason I know. Another suggestion was to bring the blank back to Make It Here and use the ShopBot to flatten the bottom. I wouldn't be able to do that before tomorrow. So based on yet other suggestions this is what I'm going to try. This is just a mock up, I will use a screw chuck, but the vacuum was on the lathe. Sand paper on a board with double sided tape. The board mounts to a face plate and spindle adapter and is restrained from rotating by the ways.

    If I can't complain about the results, then I don't care who calls it cheating.

    In between glue sessions I have been re-working the design for the last couple of days. In this version the pillars or bands rise up a little more steeply and roll into a tighter curve at the top. The basin then droops or hangs down a bit. The basin itself is the same diameter as before, but is a little fuller than the previous version. I'm not sure whether or not I will take the time for another model, but I can incorporate some subtle changes without remodeling. Do you like the earlier or later version better? Any (preferably small) changes?

    So this turns out to be an interesting problem. And I just gotta stop and say, I hate interesting problems. I mean if you're gonna have a problem couldn't it be just a boring I've solved this a hundred times problem? No, it's gotta be "interesting". So the stack has developed a rocker bottom. I don't know if this is because the tips of the stars have had some upward stress in the jig and this is a cumulative result, or if this might be that the glue layer is somehow thicker in the body of the star than the arms, but there is just enough curvature that I can't really get the next star to make good contact along all four arms regardless of the pins. Not sure how to address this issue so I'm going to let the glue up sit for a bit while I think. I wish I had a thickness planer (but I don't), assuming the top is flat I could just shave off a little from the bottom and return to flat. I could probably find a club member who could help me. I could place a thin shim under each arm, but I would probably have to abandon the alignment pins. Any thoughts?

    Well if it makes you feel better we've left that number behind. 56. Only 42 more to go. Apparently I was delusional, I thought this glue up would take a week or so, but in reality on a good day I'm getting 5 or 6 stars glued up. I am a little concerned that some of the stars may not be adequately bonded. The problem is with that tiny bit of swelling the veneer does when wet with glue. The tip of the star on one end always overrides the pins. Up til now that has not been a significant problem as the press forced the layers together. Now the growing block has become so thick as to resist the clamps and leave a significant gap. Whether or not this matters will depend on whether this section ends up being turned away or remains part of the final design, but I'm going to have to inspect for these and try to get some adhesive in there (hence the question about low viscosity epoxy in "Finishes"). I am going to start nipping the tips off with a knife to make sure the block lays flat against the next star.

    I hired a moving company today. I found a local outfit much cheaper than 2 Men and a Truck. I should have it out this Friday. As an added benefit I think they will set the thing down in the mobile base at my shop so I won't have to figure out how to lift it in. Don't get me wrong. There's nothing wrong with the suggestions, but there's a difference to what I will do in my house or a buddies house and what I can do at a stranger's house.

    Thin Epoxy Adhesive

    I have the watery CA glue, but CA tends to be brittle and may not be able to stand up to the shock of being turned. So epoxy can be diluted with acetone, but it will diminish the strength.

    Thin Epoxy Adhesive

    Thin enough to force through a 20 gauge needle, you think?

    Thin Epoxy Adhesive

    Is there such a thing as low viscosity epoxy adhesive? I would be interested in something watery.

    Or it may be a component of a larger apparatus.

    Yeah, there's no "what not" to buy in turning. It's all "what".

    Thanks for that thought. Don't give up on the stair climber entirely. It did move the drill press and the cast iron top after all. But it turns out that besides weight, the center of gravity of the load and slope of the stairs are factors.
