How to program a job that is higher than your Z possibility

c.f.,

Makita RT070XX with an ER16 Collet Chuck? Yup

Story TIme… A long time ago… I raised my Shapeoko XY, and Z (rails) about 1.5625" (lol) inches. This was AWESOME because I run a lot of larger parts AND this ALSO meant that the Z would clear my 4th-Axis’ 4.0" (100mm) 4-Jaw, BUT this also meant that I could no longer reach my aluminum table. [IMG_6847] When needed, I would place a 3/4" plywood on top of some 123 blocks…not great, but it worked; however, I longed for my beautiful ultra-flat aluminum table. …then a few weeks ago I saw a post…

but note the caution at:

Motor Shaft Extension ER Collet

The thought of someone putting extensions in a high speed router that was NOT designed for this scares me. In aerospace we also use industrial high speed motors for cutting Nomex honeycomb core. An employee was killed by an out of balance long cutter (tool) they went right through his chest, severing his aorta…Meaning LONG unbalanced (G2.5 and G1.0) tools can be VERY dangerous projectiles. PLEASE DON’T DO IT.
