I was on fire today! I wish it was figurative, for if anything, I was the opposite of “on fire” in terms of my working speed today. But alas, it was literal. Its been a while since that happened. Its kinda exciting every now and then. It burnt the hose too, on the torch.
So, first thing today, I was gonna freeze fit the bushings. I did one yesterday with just normal ice, and it worked fine, I just had to use the press to push the bushing in. I figured I didn’t need to buy dry-ice, since it worked. I was wrong. I did one successfully today, using the press. The second one wouldn’t go all the way thru. I flipped the piece over and discovered horrible galling, and material displaced! After talking to the guys, I found that was because the bushing must have gone in sideways, and the press kept pushing it in , so it scraped away excess material. They said this happens to the best of em now and then, that they’ve all done it. See vids.
Seems like there’s really not any way to prevent it if you’re using a press to put them in. You can be more careful that it doesn’t get cocked, but it’s really hard to tell when you’re doing it.
My solution is simply to use dry ice. It worked really well before, and it’s relatively cheap (~$6.50 for 5lb). Best part is that it will make the bushings go in with just a hammer. Or even with your hand.
I shipped the welder to OSE today. It took up about 2.5 hours to get it shipped. Jimmy taught me how to use the packing machine. I forget what it’s called, it uses metal straps and crimpers. I also shipped the cylinder and a gas cut-off saw that Marcin bought from my uncle. See the pics in the gallery below.
I began on the cylinder mount. I did things in an odd order because it was so small. See video below. First I torched the radius, but didn’t torch it off. This is so I could have a center mark to torch from. Then I mag-drilled out the mount hole. After that, I torched it into a piece slightly bigger than the mount. This was so I would have something to clamp it to while I machined it down. Then I machined it to the proper thickness, and bored the hole to exact diameter. After that, I finally torched to proper size. See photos.
