As is, the deformation of the maple as I cut it to make the 2x2 blanks, may need a lincurve to correct the Z axis in case it warps as I cut it, but that would be almost on a per stick basis. Shudder... However that may be forced on me if this kiln dried maple does warp. A bit of warp can be tolerated by the nuts as they only engage 2" of the screw, and correcting for that would be preferable to running out of wood to make the thread. That would take a lincurve in the z, referenceing the mod[b position) plus a linurve to drive a z scale driven by the y position. At least 4 more modules in the z path to apply it all. The cpu has the cajones to do it, do I have the time and paience to calibrate it? That IS the question. :o)
This maple looks good, but I've not yet engaged it with a sawblade. Have made a couple gunstocks for a BP rifle, I know better than to expect it not to warp unless its been vacuum dried for at least a year. Under a 29 inch + vacuum. Zero moisture IOW, and this new stuff is likely no dryer than 14%. I'll find out quick enough. Like the saw kerf 6" into the first cut. Thanks Ken, you made me think outside the box, and thats always appreciated. Cheers, Gene Heskett. -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
