Hydraulic cylinder question

[alanganes]

I have left my four jaw chuck in one of my lathes for a while now. I put it on there to do some sort of fussy work on something and decided to just leave...

I did convince myself it was Blackhawk. The actual nameplate was missing but you could see the rivets where it once was. There was a number I think in...

Thank you guys.

JT, this is a single acting cylinder, and it does somewhat self retract so I presume there is a spring in there. I did have...

A while back I had posted about an old Blackhawk hydraulic hand pump that I had cleaned up and repaired. I was getting about working on freeing up the...

There is a good write-up on microwave oven theory, including details on the transformer design and behavior here:

It weighs in at a bit over 250 pounds. So yeah, it's a sizeable tool....

[alanganes]

That's around 16 bucks/pound.

Your assumptions are more or less correct Bob. The stacks of small laminations you see between the coils are magnetic shunts. When the thing is not under...

I got a $100 amazon gift card from work a while back and used it to get one of those small Noga arm/base units like the one linked above. The way the...

[alanganes]

I always just assumed that it was simply much more convenient than using an open flame made by a match or whatever....

I was going to point out pretty much the same thing. My lathe uses a very similar setup minus the threaded collar. The outboard end of the spindle is...

We have a central vacuum in the house, and when I installed it I made a point to put an inlet connection in the shop. It's super handy.

As...

I'm not suggesting these are high quality. The criteria put forth was "low price and a 3" hollow shaft, possibly by drilling them out"...

[alanganes]

Dare I suggest the obvious: Harbor Freight...

They do list some of the sets as having hollow shanks, but don't specify how deep the hollow...

[alanganes]

Thanks. Interesting stuff. Where I live in Massachusetts, most anything that fun is somehow illegal.

I really like the setup on the large...

Never mind frozen viruses. Didn't you see John Carpenter's "The Thing"? You just don't know if you are thawing out a frozen alien.
Then...

One example here. Zoom in on the picture. The dial covers 0.2" per revoloution, so there is a zero at 12 o'clock and another at 6 O'Clock:

In addition to all of that, while I don't know what an off shore drilling platform weighs and I'm too lazy to Google it, I think it's a safe bet to think...

Again, thanks for posting your progress. I am really enjoying following along.

If you don't mind my asking, were do you shoot these things?...

I do recall some years back when Grizzly first purchased the SB name and rolled out a couple of models of new SB lathes, said lathes took a bashing on...
