Lessons Learned: Waiting for replacement bits in the mail (twice) is slow progress, have spares on hand. I was a bit (pun intended) too aggressive with my tapered end mill and it snapped at the tip. I did not have a spare so ordered another set from Sienci Labs. 5 days later received and started the finishing pass again. I lost my zero since Windows decided it was time to install updates… Good timing Microsoft. Reset mu zero and ended very close to the original. Started the finishing pass again and was moving along nicely. Paused the cut to get some sleep. Started the next morning but after 30 minutes of cutting lost the USB connection to the Longmill. Not sure what happened there. In my frustration I move the Y azis instead of the Z axis and snapped my bit again (learned patience). Down to my last bit again so I immediately ordered 2 more sets from Sienci Labs just in case. Waited until Saturday morning to try again. Reset my zero, started the finishing pass and made it to the end after 21.75 hours. A few rough edges because of the re-zeroing but salvageable. Cut the peg holes, lettering and lines in about 30 minutes. Now on to finishing. I will be away for work during the next few days so not able to complete until next weekend. Planning to finish with Tung Oil. I may try to add a trap door with magnets on the bottom to hold the pegs and line that with felt. Really happy with the outcome.
