Laser Cut Helically Segmented Sierra Blank

[Ken Wines]

This is 5 strand, one revolution helical blank that was laser cut and fits Sierra tubes. I cut 4 segments from 5 species of wood and pieced 4 blanks together from the results. You're probably wondering why 4 total blanks and not 5. The segment's are width adjusted to compensate for laser kerf which rendered the 5th segment in each source blank smaller than the others. The first photo is a glued up blank. The second photo shows the source blanks. The third photo is the glued up blank on the left and the other three non glued blanks. The woods are osage orange, aromatic red cedar, walnut, cherry and maple.

Super job on these spirals! Glad you compensated for the kerf.
In looking at these, I realized this is left handed as in a bolt with left hand threads. How hard is it to tell the laser to do a mirror image...right hand twist?
Just curious.

Charlie, It's rather simple to change the rotation. It's just a matter of flipping the cut lines, one mouse button operation.

That workup would make a great YouTube video.
