Yesterday was my birthday. My present to myself was a Spectralight 0200 CNC Mill from eBay and an small metal casting foundry set. I picked up the mill last week and installed it Sunday night.
The Mill is based on a Sherline 5400. The one I bought has a 3/8's inch Jacob's chuck and a small milling vice. What's awesome about this one is that it didn't require any fritzing. It had a PC with the control software installed, the software, the interface card, the control box and the mill. It was literally plug and play. I was _really_ excited to get it in and set up.
The good news: It worked!
I didn't have any end mills, so I bought a HSS 1/8" Spiral cutting wood bit. I chucked it up. (Crap, it didn't include a chuck key.) and mounted a piece of pink foam in the vice. (Crap, I don't know how a machinist vice works.). Then I turned the spindle on (Wait, it isn't working. Here, let me screw that connector a little tighter) and jogged around in the foam to make a cut! (Success!)
The bad news: [It worked] ... for about 15 minutes.
The Y axis stopped moving. I can see the Y axis stepper turning, but the slide doesn't move. I pulled it apart and the leadscrew was pulling out of the thrust bearing that holds it in place. I pulled the Sherline parts manual and it looks like there is a socket head cap screw in there that must have failed
Specifically, I think that my 67115 has come out of the leadscrew or my 67105 has busted. Back at the mill there is a big rubber something that is wrapped around my 67105 coupler. I don't know if it's just a safety don't-put-your-finger-in-this thing or if it is some sort of vibration dampener. I didn't get another chance to work on it this weekend, but it's my first priority for next weekend.
I am giddily excited about this. There are so many things I want to make now!
p.s. My son's first question was "Can I try?". His second was "Can we make an AR with this?" :)
