Today, it was raining outside, so I tried hard to tell myself to work in the garage again (the winter blue is a bit hard on me). My 3 phase rotary converter stopped working. I thought it was something to do with the capacitors. I checked every one of them with a meter, and they all looked ok (with the uf rating, not true test). So I wiggled all the connections and they seems good.
For a good measure, I went back to each connection and tighten them up good. I also happen to have a same size start capacitor, so I replaced it since it couldn't start. While I was at it, I saw the motor has 2 oil ports, so I put in some oil, and I didn't know what oil to use, so I just used way oil
After that, it started up really well and I don't know what caused it. It's likely the start capacitor.
After that, I did a boring, and I think the chips messed up the surface a bit. I used a toothbrush to clear them up, but I guess blowing air continuously on it would help. What do you when boring to clear up the chip? I am really worry about blowing air, since that push chips deep into machine area that they shouldn't be there, although I saw many people doing it.
After that, I did some interrupted cut and some chips landed on my hands, which is really hot. I ended up doing it 1 hand and cover it with a small cardboard. Works great temporarily. People must have a better solution than this, but I didn't see anything like that on youtube. Maybe they just use auto feed. I am just a bit worry about the interrupted cut, and want to back up asap if anything bad happens.
The interrupted cuts also gave me another problem. Somehow I just couldn't dial in the cut right between cuts. So I checked and the carbide insert moved. Looked closely, it was held down by a little screw. It was part of a lot I bought before. So I took it out and it turned out it was on top of another insert, which had the middle "bolted" down with a pin. The top inserts moves around because it was barely pushed down on the top. I bought the lot from a closed machine shop auction. I suppose the person doing that must knew what they were doing. Why would they stacked inserts like that? I just cut with the bottom insert only and it worked without problem.
