This means that vibration tends to creep in and slow down the process. I can turn them reasonably well by holding my hand at the back of the piece, but still, at some point, the piece will flex a bit and the chatter starts. I use the skew to shave away the chatter in most instances, which works great, but does take some care.
A couple of years back, I gave my shop made steady rest to Tim Manney for the use on the reamers that he produces. It's the one featured in my book. I wasn't doing a lot of turning that required it and up until recently, a little slow down in turning time didn't bother me compared to stopping to make another. But I happen to have some nice plywood on hand so the other day I made a new steady rest.
I covered this jig for the first time about 6 or 7 years ago, you can see the original post and plans here. I've learned a few things that I think make it worth revisiting, plus my own rediscovery of it's usefulness makes me think that you might feel the same. The plan dimensions in the original post are still good, but with this one, I made the notch in the support block 45 degrees on both sides.
One of my favorite parts of this design is that you can cut right across the front of where the steady rest supports the work. The weighted wedge simply drops, pushing the block up against the smaller diameter.
I position the rest directly behind the largest part of the vase.
To set the steady for best results, turn the part to round, about 1/16" larger than the largest diameter, then place the steady block and wedge in position. Get the round spinning again and with the steady rest in place, take a very light pass across workpiece opposite of the steady block. This allows the block to seat on the piece and ensures that it's spinning true with the pressure of the block at the back.
Then use some wax to lubricate the workpiece. I've found that there's no need for bearing guides if you just add some wax.
Turning is fun, or it should be. I know that there is a conversation around certain jigs or techniques being crutches. I get it, but I'm having more fun at the lathe and thinking more about the shapes that I am making rather than the ways of avoiding vibration, which is a way better way to spend my day.
