SplinterGroup commented about 9 hours ago I like that application for the vac clamp! My finger tips are all about 1/2" short of "spec" from doing that sanding operation freehand.
Sharp looking box pattern, have those "cookies" ever shown tendency to get radial cracks?
It's the fingers that begged for the use of the vac... was surprised at how well it held... working on a 40-40mm diameter one... sourcing here in Aussieland is hard. The log had a few radial cracks on one end... I had to put aside 3 cookies... the 4th one split down the centre but big enough for the top (1/2 lid)... other half can be used for another box, Did a non-scientific stress test, and was surprised at how well it held out before breaking. With the glue up, I reckon it could take a drop without issues.
If your first cut is too short... Take the second cut from the longer end... LBD
