Another contracted piece finished last night.
The metal shavings in the picture scared me to death! I was thinking that I had hit some unknown piece of metal in the wood, or that the motor was grinding on something, or the v-bit was some how shaving off!
Really it was the shavings from withing the Z axis Makerslide that was tapped. The shavings had finally worked their way down the slot. Only took them about 4 years to show up!
