First day of building

There we have it. I made it through the first day. Honestly, I had expected to work all through the night, but I’m about at tired as I’ve ever been in my entire life. Going to get something to eat now, and we’ll see if I continue a bit after that.

Anyway, to summarize this day in one word: utter apeshit. That’s right, I used two words. Fuck you.

Where do I begin? Everything went wrong. First of all, I had expected to use my old cnc to mark the locations for the holes. That took about half the day to realise that my old one was alot worse than I thought, missed steps or backlash, I don’t know. It sure couldn’t place holes accurately at least. That means I had to mark all the holes by hand, which took hours and hours. For 3 pieces. The other 20+ are still on my to-do-list.

Then to the drilling. That was a lot harder than I thought, and a lot messier. You can see that even my vacuum separator gave up on life. The drilling was a nightmare, and that was before I broke a drill almost all the way through a piece (I broke like 5 other drills, but they weren’t that much of a hassle). Took me about 2 hours and a messed up hole to get it out.

I tried to polish one of the pieces to get it to look a bit nicer. It didn’t turn out as nice as I had thought, but I only spent about an hour doing it, I guess I should expect three times as much to go through grits 180, 240, 500, 800, 1200, 1500, 2000 and then the polishing wheel.

Oh well, food now and a new try tomorrow.

    Little-known but amazingly effective trick for extracting broken drills and even better broken taps from aluminum: sodium bisulfate, available as sparex pickling compound.
    Put 100 grams or so in a crock pot full of water, get it up to above room temperature, put your aluminum in, and come back the next day. The aluminum will be grey with a very slight etch, like 0.05mm, and there will be no sign that the steel was ever there. It’ll be completely gone, dissolved away. It’s saved a lot of parts when I’ve broken off a tiny tap near the last step, if I can handle the resulting very dull finish.
