steb centers
May 17th, 2017 at 7:41am
 
good morning! I've been kickin' around the thoughts of steb centers. Being fairly new to the turning world, I'm wonderin' if the investment would be worth it. I have done some research in my limited time available, but the concensus seems to go both ways. I haven't really got into any serious turning yet because of to many other projects going, but is the steb designed for a given type of turning? Does it slip under pressure? What are they designed for? I'm not to interested in bowl turning at this point, but I've got projects in the works that are going to be hollow form types. Hope this "question" makes sense. Thank you in advance for any info & advice. Brad.

Brad,

Steb is the name of the inventor of the center bearing the name.  Sorby licensed the patent and sells drive and live centers by that name.   There are similar knockoffs on the market.  Last I looked, the knock offs are not the same diameter as those sold by Sorby.

I have used the 1/2 inch Sorby Steb brand centers for many years for small to moderate sized spindles.  These are a form of "safety centers" that will spin with a serious catch.  In teaching kids to turn, they help reduce some risk and build skew confidence.  I like the small size for preparing spindles for small projects using irregular wood.

I have tried a couple of knockoff versions.  They are larger, but find I come back to the Sorby version.

These are not an essential tool.  But I find them handy for spindles up to 1 1/2 inch or so.  Really small stuff like knitting needles they apply too much compression.  Bigger than 2 inch is too much for the small sized one I have and I use a large drive center and live center

As usual, the answer depends on what you are doing.   

Safety centers are a good approach, and can come in several forms.

Yes
Yes
spindles

Like Ken mentioned, Steb has sort of become the generic name for this type of tool. They are primarily designed for spindle turning. The multi-tooth design is to engage the wood at multiple points (more surface area, points of contact) making it more secure. While at the same time not splitting the spindle if there is a catch but operating like a clutch slip. If/when a slip does occur, the center can simply be re-seated, with no significant damage done to the spindle, other than a small circle where the teeth were engaged.
Once I started using a steb "style" center I don't use the standard 4 prong drive center anymore (hardly ever).

Just my experiences.  They can/do slip with a catch.  What I use mine for is small dry spindles under 2" diameter and small dry face work under about 7".  For the face work I mean like a small platter, saucer, or other thin item where you may have a limited about of wood to be removed; this could also include small winged bowls (Clewes style).
I can't see where they would be any/much use with hollow forms that a 4 spur will not handle just as well or better.

For most spindles you can use your 4 prong but the steb really comes in handy where a spur would be hard to seat such as on a platter.

Thank you for your input. That pretty well satisfies my curiosity. I'm thinkin' I'll just stick with my four prong that came with the lathe, & put the $$$ towards a chuck. I just have a faceplate at the moment. Thank you again..brad.

That's the point, they are supposed to slip. No damage to the wood (splitting) or the turner.

I understand putting the cash towards a chuck but I will mention that the Sorby brand centers cost 3 times as much as a comparable Woodcraft brand. (and that's on sale)


A little off topic
It may just be me but why would you use a drive center of any kind on faceplate work?

i don't. I just mentioned the fact that I have a faceplate for now, & instead putting money towards the steb, I would keep saving for a chuck. my apologies for offending you, Ed. I don't use the faceplate, either. I haven't gotten deep enough into the "vortex" yet to learn all the vocabulary yet, nor done enough turning to even consider myself a turner. Most of what I have done to this point I've learned on my own, & figure things out by reading & research. Less the humiliation of asking questions about the things I've never used or been around. I just had the crazy idea I might get some information here from you turners that do know. From here on, I'll be more cautious of how I word my posts. Thank you for your time, & allowing me to be on this site. brad.

Brad, Nothing wrong with your posts at all. Just ask - and you will receive. Throw caution (about posting) to the wind. No such thing as a dumb question - the questioner is usually answered by a smart and experienced questionee (maybe the other way around  Shocked ).  I'm dumber than a blade of grass, but I still get answers to my stupid questions! I think some of the answers are dumber than I am though (!) Not.

Brad, you have me a bit confused.

I think you may has misinterpreted my response.
1. I was simply saying that it isn't necessary to spend the higher price for one particular brand, there are less expensive alternatives.
2. The question about using a steb center on faceplate work was directed toward Mike Mills, who indicated that, that was his method of work.

Please feel free to ask anything you want, we all had to learn this information somehow.

ok. well, like i said, i'm new enough to this that I'm still makin' more firewood than presentable projects. Lately, family obligations & my health have kept me away from the shop. After nearly 4 months, I was finally released from pt this week, so hopefully shop time will pick up. And, like i said, i've got a few ideas for projects, but have several scroll projects to get caught up first. I appreciate your explanation, Ed. I've learned alot here & didn't want any enemies.

Brad

Like Ed, I've been confused by the various posts in this discussion.  And with several thousand hours on a lathe, I'm sometimes still feeling like a rookie when I try to go in a new direction.

A spindle could be a chair rung, a table leg, a rolling pin, a walking cane, . . .  Spindles usually are engaged at each end, and if the tailstock is backed off the spindle falls onto the lathe bed.

The spindle is turned by some sort of drive center in the headstock - a four spur drive center, a two spur drive center, or a cone or steb center.  The latter two are sometimes called safety centers, as the spindle can stop turning if there is a catch.  The drive centers almost always have a morse taper that slips into the spindle.

A faceplate is used for larger diameter "stuff."  They can be used for turning bowls and "face work" like the base of a table or floor lamp.  Screws secure the wood to the faceplate.  If the work is out of balance, many people will bring up the tailstock until the work is balanced, then the tailstock usually is not engaged.

Like a faceplate, a chuck secures the work at one end (although the tailstock may be used initially for additional safety) but does not leave screw holes in the end of the work.  Some attach a waste block to a faceplate, then adhere the work to the waste block and part off the work from the waste block when done.

With proper screws in proper number, a faceplate might be a more secure holding than a chuck.

Everyone has their own preferred leaning methods.  I started with book/video pairs by Richard Raffan, and still find them valuable reference material.   There are a number of quality videos on this forum.  A friend or neighbor can be helpful, but a turning group can be even more beneficial as one is exposed to different approaches and favored techniques.

Different types of projects - spindle,  bowl, faceplate, inside-out, . . . - involve different mounting approaches, different tools, different techniques, and so on.  It can be difficult to stay on one path initially, but you might find it helpful to focus on spindles for a while, even if just making fancy pieces of kindling, to develop confidence with some of the tools and terminology.

that's my thoughts, Mr. Stephen. I've made a few chair rungs, a few s & p shakers, a couple drinkin' cups, but nothin' fancy. I'm tryin' to fit the lathe into some of my scroll projects, but It seems I don't have much time to get on the lathe:(. I keep workin' towards the goal of spending more time on the lathe. And thank you Ed for the health encouragement. I appreciate it.

Brad,  the folks at Gwinnett Woodworkers on Youtube have a few scroll saw lathe combinations.

I guess I used the wrong verbiage.
As Don stated, "spindle" can be lots of things from the namesake to pens, pepper mills,...anything with the grain running parallel with the bed.
I was not referring to "faceplate" but what I was taught as "face work" meaning the grain running perpendicular to the bed of the lathe.  "Face work" can be held by a faceplate...or drive center, woodworm screw, pin chuck, scroll chuck and other methods.

It may well be that steb centers were designed to slip.  My impression is they were made to provide a tenacious grip with minimal damage to the wood.

Just for slippage I would suggest a safety drive ($) compared to a steb center ($$$$).  My safety drive was $4 new; they are just a simple cup & point dead center for the tailstock which greatly increases in value when moved to the headstock. Grin
