This looks good. I have been wanting to make a fixed steady for goodness knows how long and this gives me an idea for a simple effective build.
That is one nice build. Certainly nice to see a different approach to an age old device.
I really like it; especially by leverage taking place of small diameter fine threads for accurate adjustment! Brilliant, no question. And the frame, a section of heavier wall pipe/ tubing, points out many alternatives to heavy castings.
Again, Terrific concept. In one way, not surprising, you do such good fabrication work on those sanders and grinders.
Does anyone know why the lathe tool had that texture from the toolpost to the shaped cutter? While I was watching it in use, I kept wondering what would have made those marks and are they there for some particular reason, or are they just an artifact of the manufacturing process? I thought it was a spring in the video's thumbnail, which begat many more questions. Oh, and the steady rest is very nice, too.
Hard to know what period you refer to, out of 15 minutes of video. Hover cursor at the general frames in question and the time is displayed. Closest thing I see resembling a spring occurs turning OD of the spud outboard of the steady rest; it's cutting through crests of threaded portion. Change in profile and surface finish makes helix of thread root a bit more visible.Quote:

By changing the clocking of the pivots from the 12-4-8 positions to the 1-5-9 and angling the adjustment bolt on the rear arm to about 30° from the angle it is mounted now this will bring the rollers closer to the true pressure points needed over a wider range of diameters it will still be a compromise as all steadies are to a certain point but will be much closer than what he has now
About half-way through, when he starts machining parts, I noticed the tool he is using, not the part he's making, has what looks like machining marks running around its circumference from the tool post out to where the cutter is ground. The texture is almost like the tool was 3D printed. I'm guessing it may have been cast, and those are marks from where the mold was originally carved out. It doesn't have anything to do with the piece he's making, just something odd I saw and couldn't figure out.Quote:

Ooooooh, the cutter! Little too focused on the work; typical for me.Quote:

I'll bet that's it! The bend threw me for a loop, but you're probably right. I guess I was trying to think too hard about it. I wondered why I smelled bacon burning...Quote:

Since it is a short, tapered length, he probably hand-turned it with the compound rest set at the angle. Under those conditions it is difficult to have a smooth, continuous turning motion as you stop to reposition your hand on the handle to complete another turn. Each pause will leave a "spring" mark. If he used a taper attachment then it was set up lose and backlash (or feed rate) is the cause of the rings. Since the pitch of the rings is so consistent I suspect it may have been power driven in some manner.

Now off to find a piece of thick wall large diameter pipe!!!! Or, maybe start with a smaller one. Come to think of it, I think I may have a piece of 4" schedule 40.....
