Machinist Apprentice | FB Virtual Convention & Pocket NC Coolant System | Day 93

Didn't work on anything super exciting today, just continued cleaning up the rocket model and programming it. 

I also spent a good bit of time helping my boss set up for a virtual convention hosted by Facebook for small businesses that wanted to promote their company and connect with new people. I got to watch the opening presentation for it and some of the people who spoke after, and it was underwhelming, to say the least. Unfortunately, it was heavily focused on supporting minority groups and LGBT+ in detriment to other businesses. I personally don't really have a problem with companies supporting those groups. But, they are barring some companies from participating if they don't fall into the minority groups and limiting their influence. 

I also spent a bit of time playing around with the Pocket NC. I recently picked up a cheap 0.001" dial indicator off of MSC industry and hoped to build a fixture to hold it to correct any spinout the tooling may have. Unfortunately, after taking a closer look, I thought that adjustment screws on the tool holder's base were merely set screws used to lock it in place. There might be another area around the spindle area, but nothing popped out at me. I decided to check what the runout was and was pleasantly surprised to find it only about one thou from high to low. Still isn't ideal but not as bad as I was expecting. 

While poking around the spindle carriage, I noticed four threaded holes in each of the corners. I'm not sure what they are used for if anything, and may have been for some future feature Pocket NC was going to add or remove. I mention this because I've been considering adding a coolant system to my Duif Workholidng site that would activate with the spindle, and making a piece to mount over those holes would work really well for that.
